The European Machine Tool industry, represented by CECIMO, has launched a European initiative focused on sustainability: the Blue Competence Machine Tools initiative. The Blue Competence initiative (BluECOmpetence) is led by Germany"s mechanical engineering association, VDMA, with activities up to now centred on that country. The machine tool industry is the first mechanical engineering sector to embark on a broad-based campaign on sustainability at European level. Under the initiative, companies agree to meet pre-determined ecological, economic and social values and principles, while implementing sustainable production solutions in their production plants, products and business services, with the aim of achieving greener manufacturing. The initiative is in line with EU policy developments and priorities.

Martin Kapp, president of CECIMO, said: "This landmark initiative underlines the willingness of European machine tool builders to make a leap forward towards a better and greener manufacturing perspective. Production technology and equipment supplied by the machine tool industry is the key enabler of resource efficient processes in all other manufacturing industries. Now, our manufacturers are taking on a firm commitment to align, in a holistic approach, their products, processes and business models with sustainability principles." Filip Geerts, director general of CECIMO, added: "Blue Competence Machine Tools is about "competitiveness", "environment" and "quality of life". It highlights the contribution that the machine tool and other manufacturing industries are making to economic and social life as well as to the protection of environment. CECIMO expects the initiative to profoundly influence business and manufacturing practices in the sector; to stimulate technical innovation; and to raise awareness about the role of manufacturing in driving sustainability.

"Blue Competence Machine Tools is an excellent example of partnership in which industries work together to tackle the common challenges we face in Europe." To meet the trend of modernization development and the needs of international markets competition, our company has been introducing senior management personnel, scientific and research talents, and advanced graduates continually. And we are taking advantages of advanced technology from United States, Germany, Japan and other countries to achieve self-innovation and effective development.

Our company has been adhering to the concept of "people-oriented, customer supremacy, development and innovation". We are able to provide our customers not only the highest quality products at the most favorable price, but also the most reasonable suggestion of equipments, optimum process configuration, and a full range of technical support. In pursuit of bringing customers the most benefits with minimal investment, we have been trying our best to help customers in any case! As a leading global manufacturer of crushing and milling equipment, we offer advanced, rational solutions for any size-reduction requirements, including quarry, aggregate, grinding production and complete stone crushing station. We also supply individual cone crusher and dryer machine as well as spare parts of them.

The base component of the ore mill not only supports the whole weight of the machine, but bears the dynamic load resulted from the impact and vibration produced by the operation of the equipment. The loading capacity and the stability of the base are the most important factors that relate to normal work of the devices and at the same time, we should make sure that the base will be submerge or crack in the operational process of the mill, for this reason, the base of the equipment should be installed onto the solid foundation, and is has high and strict requirement to the weight of the steel concrete which must be two point five to three times of the grinder. The base cannot be linked together with the footing of the wall or the pillars of the plant and under normal circumstances, the distances between them should be kept 1 meter and at the same at least 40 to 50 mm. If the distance is too small, the workers should fill with the slab stone in order to prevent the vibration of the building during the operation of the ore mill.

Before the installment of the ball mill, the workers should examine and check carefully the relative position relations between the base and the adjacent buildings and structures and the adjacent machine sets and make sure the their distances are conformed to the stipulations on the design drawing. There are many methods in the examination process, for example, measure with the measuring apparatus from a certain fiducial point or measure using bracing wire. All these methods are used in order to find out exactly the mutual position relations between them and figure out precisely their main sizes, for example, make sure the horizontal distance, depth of parallelism and verticality, levelness and relative altitude difference of the axis of the ball mill, the gear axis of the reduction box and the axis of the motor and what is more, in order to make sure whether the position and dimension of the obligate hole of the foundation bolt are conformed to the requirement of the design paper and the actual production conditions and whether the actual size of the screw hole on the bottom of the ball mill are all the same. After the check and examination work is confirmed and the workers can maker sure that various kinds of parameters are exact without error, then they can proceed to the installment work after figuring out the positions and sizes.

In addition, before the installment of the ball mill, the technicians should examine uniformly and completely all the ore beneficiation equipment in order to make sure whether the equipment are all in readiness and whether there is any defects and whether they are conformed to the installment and working requirement and in the meantime cleanse the main parts of the machines and inject oil into them.

Executives at manufacturing companies across state are grappling with a perplexing dilemma: Despite unemployment remaining at a traditionally high level, manufacturing is being crippled by a lack of skilled workers. This problem is not new. Manpower Inc. reported in its “2009 Talent Shortage Survey” that manufacturing-related occupations — skilled trades, technicians, engineers, et al — rank among the top five positions that employers were having the most trouble filling. Fast forward three years later, and the problem is not getting any better. An October 2011 survey from Deloitte and The Manufacturing Institute showed American manufacturers cannot fill as many as 600,000 skilled positions.

More disturbing is that the survey results show that while 67 percent of manufacturers say they have a moderate to severe shortage of available and qualified workers, 56 percent expect the problem to increase in the next three to five years. Demand for skilled workers is at a peak, a crescendo that threatens to drown out any possibility of a recovery in the sector. Sixty-four percent of respondents to the Deloitte survey say this lack of talent is having “a significant impact” on their ability to expand operations or improve productivity. Many West Michigan manufacturers are tired of the search for talent. They are finding they have to grow their own.

"People are just starting to realize that they need to grow these skilled workers from within or with internships they can use to train them in the most beneficial way,” said William C. Small, VP of technical services at The Right Place Inc. and west regional director of the Michigan Manufacturing Technology Center. “That can be quite an undertaking.” The trend of companies developing internal avenues for talent development is in its infancy, Small said, noting that many seasoned people on the manufacturing shop floor are being asked to step up to management. While Small said many people believe candidates have a great opportunity to pursue CNC machining, for example, he believes the need among local manufacturers is a little more general than that.

Now, they don’t feel so blessed. Sources say that not only are the veteran skilled workers gone from the industry, but also the younger generations — those at ages when people historically went into manufacturing — want nothing to do with factory life. They’ve been tempered by a negative image many people associate with manufacturingof vibrating screen and other mining machines such as Raymond mill. They — and their parents, in many cases — believe it is dirty and dangerous, even though advanced manufacturing is none of the above, experts say. That has been a problem for manufacturing since the mid-1970s. But now the sector faces a new dilemma. It was counted out for so many years, and its rebirth has been totally underreported.

Sand is one of the key components of concrete and sand pulp, and it is also the fundamental raw material of civil construction and engineering. It can be divided into natural sand and artificial sand. Natural one is formed in nature condition (mainly from rock weathering). Generally, we call it natural for the rock grain size is below 5mm. Artificial one is manufactured sand, which refers to the rock grain size less than 4.75mm which has been processed and screened by crusher machines. The standard one is divided into three kinds of coarse, medium and fine according the modulus of fineness.

Coarse: the modulus of fineness is 3.7-3.1, the average size is above 0.5mm

Medium: the modulus of fineness is 3.0-2.3; the average grain size is 0.5-0.35mm

Fine: the modulus of fineness is 2.2-1.6; the average grain size is below 0.25 mm.

The modulus of fineness is finer, the sand is coarser. The range of modulus of fineness for regular concrete sand is 3.7-1.6. The medium size sand is better. Or you can mix little fine sand to coarse sand, and the mixing proportion is 4:1.

The grain composition of sand refers to proportion. The space cavity of two same-sized is large, and it will be small under the condition of the proportion of two different grainsizes; it will be smaller if there are three kinds. So, the rate of space cavity depends on the proportion of different grainsize. It can save cement consumption, and increase the density and strength of concrete and sand pulp if the proportion is well.

Hongxing Machinery produces a wide range sand maker or we can also call it vertical shaft impact crusher, with the advantage of low consumption, cost effective, the final product size is shaped well and low iron and dust pollution. Its fineness size can be adjusted, so the sand and gravel proportion is well, which is suitable for providing aggregate to highway, railway, civil engineering, dam construction and concrete batching plant.

This machine is a high-efficiency rock crushing equipment with home and international leading level; the machine is developed by introducing the crushing theory and technology from Barmac Company of America and combining the actual situation of sand making. It is widely used for crushing of hard and brittle materials, such as rock, grinding material, refractory material, cement clinker, quartzite, iron ore and concrete aggregate; and it is especially suitable for the sand and sandstone making for construction and road paving.
