The ammonium chloride extrusion granulator is also called the roller press granulator. The working principle of the right-roll extrusion granulator is that various dry powder materials are added from the top of the fertilizer granulator machine
, and then degassed and screwed into the right roller. Under the action of the great pressure on the roll granulator, the material is plastically deformed and compressed into a sheet. The sheet material is crushed, granulated, and sieved to obtain granular products.
By changing the grooved form of the roller surface, flake, strip and flat ball materials can be obtained. The size of the extrusion force of the roll granulator can be adjusted by the pressure of the hydraulic cylinder according to the needs of the granulation operation.
The extrusion granulator has many advantages over the traditional fertilizer granulator machine, and the more obvious advantage is that it is extruded at one time. The granulation rate of the granulator is high. Even on rainy days it can work as usual. The roller granulator is a national patent product pioneered by fertilizer granulation machinery. The principle of the extrusion granulator is to extrude the powdery material through the roller to form particles of various shapes. It’s commonly used in the NPK fertilizer production line
It makes it easy to transport and use, no dust flying during the secondary operation, reducing material loss and environmental pollution. Roller granulator, suitable for dry granulation of various powder raw materials, can be according to needs production of granule products of different specifications and shapes. At present, the roll granulator has been widely used in the granulation of powder raw materials in industrial sectors such as fertilizers, building materials, medicine, chemicals, smelting, and coal.
Notes on the use of double-roller granulators: The double-roller granulator should be started under no load, and it is strictly prohibited to open with tape. It is forbidden to enter with materials in the material to avoid breaking the roller shaft.
Yellow dry oil should be applied to the front gear of the extruder granulator. Yellow oil should be applied to the chain and sprocket of the roll granulator every 7 days. The bearing seat of the extruder granulator should be used every three months or replaced with yellow dry oil. Gear oil must be added once before the roll granulator is used for production use, and the gear oil is changed every four months.
