The dry granulation machine adopts the dry rolling process technology to compress powdered materials with a moisture content of ≤ 5% into pieces or blocks, and then through crushing and screening processes, the pieces and blocks are transformed into granular materials that meet the requirements for use.

Dry granulation is a production process in which powder raw materials are compacted by pressure roller and crushed into granules that meet user requirements - it can improve the physical characteristics of raw material powder and solve the problems of different particle size, uneven density, poor fluidity, and easy to form layers. The processed powder has better particle size uniformity, significant increase in bulk density, improved fluidity, and its solubility, porosity and specific surface area can be controlled, and the requirements for the auxiliary material itself are not as demanding as the powder direct pressing, which helps to improve the production efficiency of the subsequent mixing or tableting proces.

Product principle:

1. The raw materials are evenly fed into the feeding hopper through a quantitative feeder;

2. The dry powder material is fed from the two rollers by spiral feeding, and the material is evenly pushed into the pressure roller;

3. The material is forcibly compressed into shape; 4. The formed sheet/strip material enters the high-speed granulator to obtain the desired particles.

Product Advantages：

1. No additives required: No water or binder needs to be added, so it will not affect the chemical properties of the material.

2. High product purity: Due to the absence of any additives, the material is directly compressed and formed by mechanical pressure, ensuring the purity of the product.
3. Adjustable particle strength: By adjusting the pressure of the rolling mill, the strength of the finished particles can be controlled.
4. Strong corrosion resistance: Reasonably utilizing titanium materials in equipment to improve corrosion resistance performance.
5. Low mechanical energy consumption: It saves energy while improving the economic benefits of production.
6. High granulation efficiency: Suitable for high production demand and efficient completion of production tasks.
7. Easy to operate and maintain. 8. High density of output products.
