Dry Granulator

working principle

The raw materials are evenly fed into the feeding hopper through a quantitative feeder, and the granulator passes through pressure rollers with different patterns, leaving a certain gap between them. The two rotate in opposite directions at the same speed. One set of roller bearing seats remains stationary inside the frame, while the other set of roller bearing seats moves on the frame guide rails and are pressed tightly against each other by hydraulic cylinders. There are many holes of the same shape and size arranged regularly on the surface of the rolling mill, and the valleys are aligned with the valleys. At this time, the dry powder material continuously and uniformly enters between the two rollers by its own weight and forced feeding from above. The material first flows freely and enters the biting zone before being gradually bitten into the valley by the rollers. As the rolling mill rotates continuously, the space occupied by the material gradually decreases and is gradually compressed, reaching the maximum forming pressure. Subsequently, the pressure gradually decreases, and the compressed block falls off the holes due to elastic recovery and its own weight, entering the crushing and screening device. The resulting product is a qualified granular product, which is weighed and packaged. The fine powder and unqualified oversized particles coming out of the powder outlet are re entered into the feeding port of the elevator by the return screw, mixed with fresh materials and added to the pre feeding hopper before entering the next round of process flow

Product Features

No need for any additives, the dry powder is directly granulated;

The particle strength can be adjusted by adjusting the pressure of the rolling mill to control the strength of the finished product;

Loop operation, achieving continuous production and high finished product output;

The material is mechanically compressed into shape without the need for any additives, ensuring the purity of the product.

Direct granulation of dry powder without subsequent drying process is more conducive to the connection and transformation of existing production processes.

The particle strength is high, and the increase in packing density is more significant than other granulation methods, especially suitable for increasing the packing density of products.

Suitable for a wide range of raw materials, the particle strength can be freely adjusted according to different materials.

Compact structure, easy maintenance, simple operation, short process flow, low energy consumption, high efficiency, and low failure rate.

It can control environmental pollution, reduce powder waste and packaging costs, and improve product transportation capacity.

The feeding and feeding device adopts variable frequency stepless adjustment control, with a high degree of automation and the ability to control multiple machines by one person. It has the characteristics of low labor intensity and long-term continuous operation.

The main transmission components are made of high-quality alloy materials. The production of stainless steel materials, titanium materials, chromium and other surface alloys greatly improves the wear resistance, corrosion resistance, high temperature resistance and pressure resistance, making the machine have a longer service life.
