Gravity screen
HVD-AS-G series gravity arc screen is a new type of efficient static screening equipment. The screen surface is made of stainless steel wedge with a certain arc shape. It can be used in a large
amount of wet material screening occasions, for the separation, screening, dehydration, washing, extraction of various materials, solids and impurities removal, etc. The separation of coarse and
fine residues (fibers), such as corn dehydration, germ dehydration, and washing is widely used in the starch industry, which is the most ideal and important equipment in the starch industry.
The equipment has the characteristics of large production capacity, good screening effect, safe and reliable use, the screen surface is not easy to caulk, long service life, reasonable structure,
and so on.
Pressure screen
HVD-AS-P series pressure arc screen is a kind of high-efficiency screen that depends on pressure to screen wet materials. It is composed of the screen surface, screen box, feeding device, and
discharge port, etc. The screen surface is the key part of the pressure arc screen, which is assembled by the stainless steel-shaped screening bar. When working, the wet material with 0.2-0.4 MPa
pressure from the nozzle, the tangential force generated by the high feed injection speed, the triangular shape is woven into the edge, so that the thin layer material wipe scrape into, which make
water and fine material evenly dispersed. The so-called "scrape" role, is to make the material easy to classify, and the entire screen surface gets the indispensable self-cleaning. Oversize
material discharge from the pot of the oversize material. And the screen underflow goes into the pulp out of the mouth.
