Classifying Screen
Product Overview
Patented Technology
Being committed to the research and development of classifying screening innovation, Haiwang is one of the largest classifying screening equipment production centers in China; the business spreads throughout the domestic and foreign nonferrous mines, non-metal mines, coal, sand aggregate, civil construction and other engineering industries. The products have features of large processing capacity, high classifying efficiency, convenient operation and stable production, which earned good reputation and trust from clients home and abroad.

Haiwang ZKJ-D multi-layer high frequency vibrating fine screen is a wet fine-particle material screening equipment developed by Haiwang Company with the adoption of the overseas advanced multi-layer design, which can realize the five-way paralleling feeding maximally with small occupation area and large processing capacity. The equipment adopts the originally imported vibration motor, internationally advanced linear motion track, 15-25 degree screen deck inclination and re-slurry technology with fast transferring speed of screening materials and high screening efficiency. The screen body adopts the originally imported float mounted spring, with low noise, low power consumption, small equipment dynamic load and long service life. The originally imported flexible polyurethane anti-blocking screen mesh (aperture can reach to 0.1mm) has features of high efficiency, high aperture ratio, anti-blocking, wear resistant and long lifespan.


• With the imported Martin vibration motor, the excited force can reach 7G (acceleration of gravity).

• With flexible hard wearing PU screen mesh, which has high aperture ratio and long lifespan;

• The screen body adopts imported shear resistant float mounted spring, which makes the screen body support almost do not vibrate;

• All the flow passing parts of the fine screen are treated with abrasion resistance, such as the slurry distributor is lined with hard wearing ceramic, the oversize and undersize collection tank is lined with hard wearing rubber and the distributor is lined with abrasion resistant polyurethane;

• The multi-layer screen distributor with patented design makes the materials are distributed evenly on each screening layer.


       The classifying screen can be used in closed-circuit grinding and classification process of iron ore, lead-zinc ore, tin ore, tungsten ore and other ferrous and non-ferrous metal ore concentration plants.

       It can be also used in coal preparation plant to separate coarse coal slime by combining with cyclone, FBSTM coarse slime compound fluidizing separator or LXA spiral separator for coal mining.

       In addition, the equipment can be applied in classification and desliming of feldspar, quartz, kaolin clay and other non-metallic mining.
