Carbon powder extrusion granulator

Main technical parameters

Product Introduction: The carbon powder extrusion granulator is a specially customized granulator for the diamond, metallurgical and chemical industries. Reasonable design, simple and practical, low energy consumption, one-time roll forming. We can customize the size and particle size according to customer needs. The process principle of roller extrusion granulation is that dry materials aggregate into dense and hard large blocks (cakes) under pressure, which is called the extrusion process; The process of crushing and sieving the cake into granules is called granulation. The function of squeezing is to expel the air between particles, and to bring the distance between particles close enough to generate attractive forces such as van der Waals forces, adsorption forces, crystal bridges, and embedded connections. The strength of extruded granules is mainly formed by the intermolecular forces between molecules. Small. The particles currently produced are elliptical and spherical in shape

The advantages of extrusion granulation:

1) Energy saving and consumption reducing extrusion granulation is the process of granulating materials at room temperature, which does not require drying measures such as fuel and gas compared to other methods.

2) The commonly used method for producing compound fertilizers in China without the need for additional adhesive is steam granulation. After condensation and crystallization between material molecules, water vapor acts as a binder during the manufacturing process. But during the drying process, it is necessary to remove the water inside and on the surface of the particles, otherwise the fertilizer is prone to sticking and clumping during storage. Dry granulation does not require additional additives and only utilizes the intermolecular forces of the material itself, simplifying the process and reducing energy consumption.

3) 3) Low investment due to the elimination of the drying process and low return ratio (about 15% of the total feed amount of the extruder), simple process flow, and low investment.

4) The raw material composition for flexible extrusion granulation production has a wide range of raw material routes, and more than 20 types of materials have been successfully used for extrusion granulation, including ammonium nitrate, urea, ammonium chloride, calcium nitrate, potassium chloride, potassium sulfate, etc. In addition, the use of extrusion granulation technology can flexibly change product formulas in a very short period of time, and one set of equipment can produce more than 30 types of products with different formulas.

5) Green and environmentally friendly, with no discharge of three wastes and the ability to squeeze granulation consumption, only for electricity. Environmental protection, with no discharge of three wastes, is in line with the basic national policy of environmental protection and the development strategy of enterprise environmental protection.
