The double roller granulator is designed by Henan Zhengzhou Mining Machinery Co., Ltd., and is an efficient granulation equipment specially designed for granulating powder and small particle materials.

After more than four years of development, the counter-roll granulator produced by Henan Zhengzhou Mining Machinery Co., Ltd. has undergone several generations of changes and is now very mature. Widely used in granulation of bauxite, coal powder, limestone, coal gangue, shale, clay, etc.

This type of counter-roll granulator has the remarkable advantages of uniform discharge, high yield, large output, compact structure, reasonable layout and small footprint. At present, it is mainly used in the ceramsite industry, which can fully meet the requirements for the granulation process of sludge ceramsite, shale ceramsite, and fly ash ceramsite.

The equipment is mainly composed of frame, fixed roller device, movable roller device, transmission device and so on. The structure is simple, stable and reliable, easy to clean and maintain, low energy consumption and long service life. It is an ideal granulating equipment in the ceramsite industry. At the site of each ceramsite project in ZK Corp, the equipment has been well received by customers.

The pair of roller granulator is driven by the motor using the belt to drive the reducer, and then drives the fixed roller and the movable roller to rotate synchronously through the chain. out. At the same time of extrusion, it can also discharge the air between the material particles and increase the density and strength of the particles.

The use of this pair of roller granulator has certain requirements on the properties of the material. For better granulation effect and higher granulation efficiency, the moisture content of the material should preferably be controlled at about 25%. In addition, due to the limitation of its granulation principle, the pair of roller granulator requires that the quality of the raw materials should be relatively uniform, and cannot contain impurities with high hardness, such as iron blocks, otherwise it is easy to damage the roller skin.

The roller skin is a consumable part. After a period of use, the diameter of the through hole on the roller skin will become larger and larger, and it needs to be replaced to a certain extent. Considering this point, this pair of roller granulator adopts the design of separating the hub and the roller skin. When replacing the roller skin, it is only necessary to remove the roller skin covering the outside of the wheel hub, and then put on a new roller skin and tighten the piece.
