The double roll extrusion granulator is mainly used for the granulation of organic fertilizer and compound fertilizer. The opposite roller extrusion production line is not used for drying and cooling process for the granulation of inorganic fertilizer, which saves a certain amount of cost. In the rapid development of fertilizer industry, the non drying production line is welcomed by customers due to the impact of environment.
How to distinguish single shaft and double shaft roll extrusion granulator?
The single shaft double roll extrusion granulator, the motor drives the belt and pulley, which are transmitted to the driving shaft through the reducer, and synchronized with the passive shaft through the split gear, working in opposite direction.
The belt and pulley are driven by the motor and transmitted to the two output shafts of the reducer through the reducer, and each output shaft drives the two grinding rollers to do opposite work through the coupling.
The double axis extrusion granulator is divided into uniaxial and biaxial. The density of biaxial extrusion material is 1-1.5 times higher than that of uniaxial extrusion material, that is to say, the particle strength produced by the double shaft twin roll extruder is significantly higher than that of the uniaxial extruder. In addition, the output is also increased by 0.5 times, and the granulation rate reaches more than 95%, and the particles are nearly round. After being shaped by the drum throwing round machine, it can be used as compound fertilizer The roundness of the particles is comparable.
The shape and size of the ball and socket on the roller skin of the double shaft double roller extrusion granulator can be selected in a wide range according to the user’s needs. The ball pressure shapes include pillow shape, semi-circular shape, shape, walnut shape, flat ball shape and square bar shape. At present, the shape of flat ball is adopted.
The whole machine is divided into four parts: frame part: transmission connection part, head working part and crushing and separating part.
This series of double roller granulation belongs to extrusion sliding model. Its working principle is that the belt and pulley are driven by the motor, transmitted to the driving shaft through the reducer, and work in opposite direction with the driven shaft through the split gear. The materials are added from the feeding hopper, extruded by rollers, demoulded and pelletized, and transported to the crushing Screen Studio through a pair of chains. The finished products (balls) are screened and separated, and then the returned materials are mixed with the new materials, and then granulated. With the continuous rotation of the motor and the continuous entry of materials, mass production can be realized.
For ammonium chloride extrusion granulation, the double roll extrusion granulator is selected. The roll skin of double shaft twin roll extrusion granulator is made of high-quality anti-corrosion and wear-resistant materials. It has the advantages of beautiful appearance, simple operation, low energy consumption, long service life and high granulation rate. The roller skin of this series of twin roll extrusion granulator is widely used in compound fertilizer manufacturing process.
