Methods of Fine Screening Machine Selection Two
The easy lift station includes a waist height table to open the bag a course griddle to prevent the sack damaging the sieve mesh, a slim line sieving machine and connection to the next part of the process. Conveying systems can also be included, if necessary, screw elevators/conveyors, pneumatic, vacuum or blowing systems, lighted elevators/conveyors - almost any arrangement. For those requiring a more versatile machine, the stand alone units are an ideal arrangement, providing users with a mobile sieve that can be positioned wherever the need is. More suitable for the batch user these machines are available from 300 diameter up through 450, 600, 700,800, 900, 1000, 1200 and 1500 diameter, each available with an array of accessories to make sieving simple and effective. Where large quantities of material need check sieving a Rotary or Centrifugal type sieve may be the better option. This type of unit can be located inline within the process and will provide high volume, dust free, continuous sieving.
When product separation is necessary there is now the consideration of multi screen machines, the requirement to provide particle sized materials means the need to consider the largest and smallest sizes required within the separation. Multi screen machines are available from the smaller 600 diameter through to 800, 1000, 1200, 1500 diameters. The mesh sizes are chosen to provide a band of material, say every particle below one mesh and everything above the second mesh other meshes being added below or above according to other band ranges required. Normally up to four mesh screens will be provided thus providing an oversize product, the first band of product, a second band of product, a third band of product and an under sized product. These and other units can be fitted with an ultrasonic declining system for difficult powders that may blind the mesh aperture. Rubber can also be fitted under the screen as a more economical method.
As the name suggests this arrangement moves the product along or down a sloping mesh. Usually rectangular in shape, the product is not restricted upon the mesh and it uses gravity as an aid to movement. This type of machine is ideally suited to those products which have a high proportion of oversize material, where it requires de-dusting or de-watering. Especially useful in those areas in the food industry where spices, vegetables, biscuits need separating from broken or small unwanted sized product. The linear vibrating screeners are specifically designed to carry out this task. With variable slope facility, and a special lateral suspension system to ensure linear vibration transfer to the screen, the product travels in a controlled bounce along the screen i.e. in a forward straight motion lifting from the screen thus re-presenting each particle as it travels down. Specially designed parallel screen systems can also aid throughput and separate the most difficult of wet and dry products.
Not all companies require large size sieves, those wishing to separate high cost low volume products very often require small table top sieves. The ZY 200 series model can provide the ideal solution. Based upon the need to check sieve and retain oversize product. This machine is available with enclosed top screen systems which allow the screen and pan to be removed in one. By changing between differing mesh pan sizes the product can be easily sieved to differing sizes, efficiently and simply. Hongxing Machinery now in its 25th year of supplying vibrating screen machinery, offer one of the largest ranges available anywhere. We have long been preferred suppliers to major blue chip and to smaller companies, we are proud to supply other mining machines such as jaw crusher and try to help all our clients.
