This crusher is widely used in metallurgical industry, highway, building, railway, chemical industry, water conservancy project, communications, mining and quarry and road paving etc. It is a machine designed to break large rocks into a more manageable size. Usually, two types can be sorted—stationary and mobile one and they can be used with any rock found in nature, or with man-made materials like reclaimed concrete. It can be used to create gravel or rock dust, or simply to smash large rocks into smaller ones. The product created this equipment can be used for a variety of functions such as construction aggregates, landscaping, erosion control and more. Currently, usage of crusher in significant application areas such as cement industry, building, paving and mining approximately accounts for 60% or so across the industry. Next, I will analyse the use of for most significant applications.

Housing as we all know is the basic need of the society. Hence, it is receiving increased focus. All the building constructions whether it is housing or industrial construction activities all require crushed stone. Therefore, with the growth of its housing industry, the demand for crushed stone will continue to grow sharply.

Annually, 10 thousands sqm of old construction would produce 7000~12000 tons of building waste every time when they are demolished in the line with the rough statistics on construction spillage of material, that is to say, reformation of the cities and towns would generate mountains of building waste. Once the range of application of jaw crusher can be extended effectively, the building resource will be saved effectively as well. Disposal of multitudes of building wastes brings about directly improvement of the living environment of citizens.

No matter highway construction or rapid transit construction, the use of vast gravel aggregate is increasingly demanded. And as the ascendant of urbanization, highway construction industry and rapid transit construction industry are in badly need of jaw crusher. With the development of national infrastructure, demands for this equipment in cement industry provide large development opportunities for merchants, at the same time, stimulate enterprises engaging in this industry to improve their core competitiveness.

Impact crusher which drives economic development to a great extent has become an indispensable machine in many application files and in socialist modernization development. After years of development, crusher industry has developed to a certain high extent with increasing capacity to manufacture. As long as possessing of innovative spirit, we believe crusher industry will have a brighter future and enjoy large market.

Using the correct installation technology knowledge and tools, we can ensure that the bearing of screen machine is not damaged. However, not all the machines are equipped with advanced instruments. In this case, the operator or maintenance engineers must keep alert on the bearing fault signal, such as noise, temperature and vibration. Listening, touching and watching are the common and simple three methods. The equipment is a new kind of high efficiency screen equipment. It is manufactured with long material screen rifling, multiple layers and various specifications. It is featured with clear screening and high screening efficiency. It has been widely used for screening in the mining and sandstone industries. It can also be used for product grading in the industries of coal dressing, beneficiation, building materials, electric power, chemical engineering, etc. So we can provide the methods of listening as your reference. It is especially designed for screening stones and features reliable structure, strong vibration force, high screening efficiency, low vibrating noise, excellent durability, convenient maintenance, safe use, etc.

We can ensure the highest bearing life through the proper lubrication and protection plan, and bearing state detection. It is a very common method by using hearing to identify irregular operation, such as experienced operator can use an electronic stethoscope to look up abnormal noise of a part. If the equipment is in good operation condition, it will have a low voice; if it is sharp sound, so bearing usually is in an abnormal operation condition. Sharp creak may be caused due to the inappropriate lubrication. The dentin the bearing outer track can cause smooth clear voice.

If we install the bearing to make percussive wound, it will also produce noise, the noise will be different with the speed of bearing; if there are intermittent noise, it means that the rolling may be damaged; After the damaged surface is rolled, if there is pollutant in the bearing, it often causes hissing sound and the serious bearing will produce irregular and great noise.

Although we can check vibrating screen by hearing, bearing must be replaced immediately at that time. So, it is a better method to use electronic testing instrument, this can diagnose ahead of the workings of the bearing. Compared with the old method, it is a more accurate method to use advanced instruments. Hongxing is a professional vibrating screen manufacturer in China, which was established in 1986. We mainly supply stone crushing machine, sand makers, powder-grinding machine and ore dressing machines and we also can accept product line or turnkey project.

As the important part of the production process of HPC220 hydraulic cone type crusher manufactured by Hongxing Machinery, quality supervision is also the significant content of quality management. This machine is widely applied in cement making industry, building, sand making, metallurgical industry, etc. It is suitable for both metallic minerals and non-metallic minerals, such as iron ore, nonferrous metal ore, granite, limestone, quartzite, sandstone, pebble, etc. Illustration of How CS Series Crusher crush through a horizontal axle and a pair of bevel gear, the motor drives the eccentric sleeve to revolve. The revolution of the eccentric sleeve makes the mantle move towards to the bowl liner from time to time. In this way, the ores and rocks will be pressed and finally crushed. At present, the quality supervisors has taken part in the whole monitor of the production process, containing machine processing, assembly, welding and other aspects.They can summarize and feedback the problems timely to ensure to meet the customers" demands faster and better.

When referring to the significance of the job, our quality supervisor has his own attitude: creating perfect quality is always our unremitting pursuit, and the arrangement of the quality supervisor is aimed at prompting the process. "To tell the truth, the pressure is really great when you are in this position. Although I have engaged in related work for many years, the supervisor is required to control the whole process, and be good at discovering problems so as to summarize and improvement. So constant learning is a must." Reportedly, in addition to the selection by the internal layers, the quality supervisor has got systematic training about law, producing procedure, and relative rules. Fortunately there is good documentation of financial outcomes at healthcare sites which use various quality improvement approaches.

According to the introduction, each test data will be collected and sorted, and recorded in the corresponding database of HPC220 cone crusher.

Time has quietly come to the year of 2012. As for the domestic industry, the infrastructure construction has lifted a new upsurge again; and what is happening in the international market? Many third world countries such as Africa and other countries has shown new dawn in the reconstruction efforts again; many such good news will promote the mining machinery industry to welcome a new year with unlimited business opportunities.

(1) Domestic infrastructure construction lifts a new upsurge.

2012 is a year when the twelfth five year plan of our nation has a strong development. The new rural construction, security housing construction, highway, and railway and water conservancy facilities construction become a top priority. The tendency that our country has a strong support for buildings will certainly increase the demand for raw materials such as cement, sand and concrete and will provide mining machinery industry with new development opportunities.

In addition, as the policy of development of western regions is promoting continuously, the rich coal and rock resources in the western region will inject new and fresh blood for the industrial development of our country. For this reason, the research and development of highly efficient, energy saving and environmentally friendly crushing equipment, coal mining and manufacturing equipment has become the magic weapon of the mining machinery manufacturing companies for taking up the western market.

(2) Third world countries show new dawn in reconstruction efforts.

In recent years, the third world countries have had remarkable period of development, especially Egypt, Libya, Iraq, Tunisia and other countries, their national reconstruction will become the first priority for the new government to win over popular support and lay the dominant position after coming to power, and road and houses construction are inseparable from the support mining machinery.

In its development course of twenty years, as the tycoon of the domestic mining equipment industry, Hongxing Machinery dominates exclusively the domestic and foreign market with mature products equipment like jaw crusher and Raymond mill and perfect service systems. Advanced technology content, high reliability, low operation and maintenance cost have enabled our products to take the leading position in the field. Our products have been exported to more than 130 countries and are widely used in global mining and construction industry. Being innovative and perfect is our incessant pursuit, and also our vigor source of energy and harmony. We will continuously create better products and better services, and always bring more value for our customers.

As the concept of energy conservation and emissions reduction gradually enjoy popular support, many enterprises and companies begin to pay attention to the research and development of high efficient and energy saving products. In architecture industry, bulk cement gradually becomes the favor object of contractors. The facts that the generalization amount of such material in Xuzhou exceeds over ten million tons and Hubei determines bulk cement as the twelfth five years development planning goal show that it enjoys good development tendency.

What is on earth bulk cement? It is said relative to the bag one. It refers to that directly transported from the factory to the freight station or end users through special equipment or containers without any small packing after it is manufactured in the factory. This industry in our country began in the 1950s and promoted to a peak in this century and has become an important part of the energy saving cause. Its development is not only the reform of the traditional flow way which will be beneficial to high efficiency and modernization of construction technology, but also has obvious economic benefits. It will make great contributions to saving resources and improving the economic benefit; improving the quality of the project; reducing the noise pollution and improving the construction environment, improving work efficiency; reducing dust and improving the atmospheric environment quality and sulfur dioxide emissions so that it has significant ecological benefits.

Hongxing ball mill is used exclusively for its production and is widely used in building material industry. This machine is the best choice for the bulk cement production machines products manufactured by which has been in wide application in all parts of the country. Demand is growing so fast and continues to grow, and you can’t cap that. The main work process is that the material evenly goes into the first mill storehouse through the material feeding device, and the storehouse has liners or corrugated linings inside, and there are steel balls with different specifications. The cylinder turns and produces centrifugal force to bring the steel ball to a certain height and then drop down to produce thumping and abrasive effects to the material. The powder material screened through the vibrating screen and is discharged through the discharging board and in the end the powder grinding work is done and the material that conforms to the demand of construction industry will be manufactured. Because the ball mill is highly efficient and energy saving and has little pollution and high processing capacity in the production process so that it enjoys high praise among the manufacturing companies.

Conventional hindered-bed separators are used extensively for classification and gravity concentration of minerals such as ore, coal, and titanium-bearing beach sands. The process can be inefficient due to wide variations in the solids content and size distribution of the feed. The poor efficiency has an adverse impact on plant performance (product recovery, concentrate quality and throughput capacity), and on operating costs (power consumption, water usage and reagent consumption).

Design improvements are needed to correct inefficiencies associated with conventional hydraulic separators. Compared with a conventional classifying machine, the CrossFlow design combines the use of an improved feed injection system and simplified water distribution system. This makes it possible to increase both the separation efficiency and throughput capacity, while eliminating mechanical problems associated with existing designs.

Operating demands, including power, water and maintenance, are expected to be significantly lower for the CrossFlow design when reporting on a per ton of concentrate basis because of higher throughput capacity. The HydroFloat separator , a novel air-assisted hydraulic concentrator , is an innovative process that combines the flexibility of a flotation process with the high capacity of a density separator. The machine"s unique design features will make it ideal for recovering very coarse particles that are too large to be upgraded by existing froth flotation processes.

Fine particle classification is practiced at essentially all mineral and coal processing operations. Therefore, the entire industry is expected to benefit from the industrial research work outlined in this project. The proposed work will initially focus on only phosphate, mineral sands, and coal-related applications. However, the technological improvements will positively impact many other mining related applications.

These goals will be achieved through two phases. In Phase I, these new technologies will be further developed through systematic pilot-scale testing of key design and operating variables at three industrial sites. In Phase II, the technologies will demonstrate improved performance capabilities in field trials conducted at one of the industrial sites, using a production-scale prototype. Data from the pilot-scale and prototype tests will be used to develop simulation programs for process scale-up and to develop optimized high-efficient flowsheet.

Upon successful completion of Phase I, the industrial team members will evaluate the feasibility of upgrading existing processing circuits and/or installing new processing circuits based on the projected benefits. Virginia Tech and the University of Kentucky will assist with flowsheet design and projected processing performance, utilizing the simulator developed during Phase I of this project. The sand maker manufacturer will provide the design and engineering functions to scale up the unit for commercial production and will also manufacture the production-scale unit. As such, we will take a leading role in the long-term commercialization efforts for these new hammer crusher technologies.

By way of Analyzing and exploring the domestic and international advanced technology and combining the common problems occurring in the production process, RedStar Machinery researched and developed new type of ancillary equipment such as energy-saving Raymond grinders, crushers and vibrating sieves and many of such machines are applied into chemical industry, building materials, metallurgy, mining and other industries, and they form a special characteristic in the country"s mining machinery products market and commit to the development of overseas market.

Material crushing is an indispensable link in the chemical industry, mining and cement and other industrial production, and generally speaking, the granularity and processing capacity of the mill is a contradiction that is difficult to coordinate because high fineness will certainly have an influence on the production capacity of the mill. In order to solve this problem, Hongxing mining machinery regard the research on mill fineness and high yield as an important object of studying. At the same time, analyze and study the high-end technology that is introduced from other countries. In addition, according to the industrial environment and market development, develop hanging Raymond mill with competitive advantages, and this kind of product not only has fine degree but the production was subsequently heightened which successfully solves the uncoordinated problems exiting in the ordinary grinding machine.

We adhere to strict scientific ideas, not only make great breakthroughs in technology, but strive for perfection in the manufacturing process. We set checkpoints in every link from raw materials to finished products in order to maker sure the stability reliability of the product quality. In the raw material aspect, all adopt high quality steel products, forgings select famous high-tech forging plant products, which adds quality insurance for the products from the source; as for the technology, we actively absorb domestic and foreign advanced technology and use it for ourselves, work to make professional model in this industry with science and technology so that the product quality and content of science and technology can be continuously improved, with the high-tech science and technology content we add a second quality insurance for the ore beneficiation products; Quality control, the company has a set of strict quality testing procedures equipment, each set of products is inspected over and over again before they leave the factory so as to add the third quality insurance. The three quality insurances effectively ensure the product quality, making the vulnerable parts not easy to be damaged and fundamentally extending the life of the equipment, thus we set a good public praise for the company with rigorous attitude of scientific research and sincere service attitude.
