The material is forced by the mechanical pressure of the dry
Granulator and the mechanical pressure is used for compression molding. No humectant can be added and the purity of the product is guaranteed. The dry powder is pelletized directly without subsequent drying process, which is more conducive to the convergence and transformation of existing production processes. Various dry powder materials are added from the top of the equipment. After degassing and spiral preloading, two equal rollers are pressed. The rollers are rotated relative to each other and the material is forcibly fed between the two rollers. The rollers nip the material into the nip for compression. The material passes through the compression zone. Afterwards, the material's surface tension and gravity cause it to escape naturally. The finger sticks after being taken out enter the smashing machine and are broken by the rotating knife row. The broken material enters into the whole slicing machine and the granules and part of the powdery materials enter the vortex sieve to be sieved through the rolling knife row. The qualified product is sent to the finished product warehouse through the conveyor. Unqualified materials are fed back to the raw material bin for secondary rolling by the conveyor. The size of the pressing force can be adjusted by the pressure of the hydraulic cylinder according to the needs of the granulation operation. By changing the groove shape of the roller surface, sheet, strip, and flat ball materials can be obtained. The high particle strength and the increase in bulk density are more pronounced than other methods of granulation. Particularly suitable for occasions that increase the product's bulk density. The dry granulator special pigment has compact structure, easy maintenance, simple operation, short process flow, low energy consumption, high efficiency, low failure rate, suitable for a wide range of raw materials, and roller pressure can be freely adjusted according to different materials. The feeding and feeding device adopts variable frequency stepless speed control and has a high degree of automation. It can realize the control of one person and multiple machines, low labor intensity and long-term continuous operation. The main driving parts of the pigment for the dry granulator are made of high-quality alloy materials, stainless steel, titanium, chromium and other surface alloys, which greatly improve the wear resistance, corrosion resistance, high temperature resistance and pressure resistance, and make the pigment dry Granulator has a long service life. It can control environmental pollution, reduce powder waste and packaging costs, and improve product transportation capabilities.
