The double roller granulator is designed by Henan Zheng Mining Machinery Co., Ltd. It is an efficient granulating equipment for granulating powder and small particles.

After more than four years of development, the roller granulator produced by Henan Zheng Mining Machinery Co., Ltd. has undergone several generations of changes and is now very mature. It is widely used in bauxite, coal powder, limestone, coal gangue, shale, Granulation of clay, etc.

This type of roller granulator has significant advantages such as 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 of sludge ceramsite, shale ceramsite, and fly ash ceramsite for granulation technology.

The equipment is mainly composed of a frame, a fixed roller device, a movable roller device, and a transmission device. Simple structure, stable and reliable, convenient cleaning and maintenance, low energy consumption, long life, it is a very ideal granulating equipment in the ceramsite industry. At the site of each ceramsite project of Zheng Mine, the equipment has been well received by customers.

The pair of roller granulator is a motor that uses a belt to drive the reducer, and then drives the fixed roller and the movable roller to rotate synchronously through a chain. The material is squeezed between the two rollers from above and is squeezed by the double shaft. The material is squeezed from the round hole on the roller. Out. At the same time of squeezing, it can also discharge the air between the material particles, increasing the density and strength of the particles.

The use of this pair of roller granulators has certain requirements on the properties of the materials. For better granulation effect and higher granulation efficiency, the moisture content of the materials should be controlled at about 25%. In addition, due to the limitation of the granulation principle of the pair of roller granulators, the quality of the raw materials is required to 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 wear out and become larger, and it will need to be replaced to a certain extent. Taking this into consideration, the pair of roller granulator adopts the design of separating the hub and the roller skin. When replacing the roller skin, only the roller skin that is outside the hub needs to be removed, and then the new roller skin is put on and tightened. Tighten the pieces.
