Double roller granulator developed by our factory is specially used to produce special fertilizer, granular phosphate fertilizer, large granular ammonium carbonate and other products. Double roller granulator is not only a fertilizer pellet machine, but also can process feed and other products. It has the advantages of low energy consumption and simple operation.
WORKING PRINCIPLE
The belt is driven by the electric motor making the transmission belt to transmit a pair of two high pressure rollers and the sliding housing to do the relative work through the reducer.The two rollers of the DZJ--I series double roller machine with the relative work of the open gear begain to working,and the two rollers of the DZJ-II were directly outputed by the two output axes on a special reducer,so that it can get the purpose of extrusion molding.
When the raw material is produced, the raw material enters into the hopper, and is extruded and molded through the high-pressure roller body, and then flows to the broken molding workshop of the lower part of the roller body after demolishing. The driving force of the crushing molding is that the chain wheel of the active roller shaft is driven by the chain to a pair of broken rollers to carry out relative motion, and the broken roller is sieved in the workroom, and the finished particles are out of the machine through the screen to the discharge slot.
The quality of particles produced by the double roller fertilizer granulator has the following two indicators:
1. Hardness
Generally speaking, manufacturers usually want the particles to be harder. But whether from the point of view of use effect or manufacturing cost, it can not be said that the harder the better. The particle hardness produced by the double roller fertilizer granulator can be measured by the particle hardness meter and expressed by the pressure. According to the variety of materials, it is generally 0.06-0-12 MPa.
2. Powdered rate
The method of determining the pulverization rate is to put a certain number of finished granules in a special pulverization rate measuring instrument, and turn them over at a prescribed speed in a prescribed time, and then determine the proportion of the powder transformed from granules in all materials. Generally, the powdered rate should not exceed 10% and the quality product should not exceed 5%.
