Is the Double-Roll Extrusion Granulator Easy to Use for Fertilizer Pellets Production?
The twin-roll extrusion granulator is a granulating equipment. It is produced by a non-drying room temperature process, one-time molding, and the output is 1-1.5 tons/hour and 1.5-3 tons/hour. The equipment has low investment, quick results and good economic benefits. The complete set of equipment has many advantages, such as a compact layout, advanced technology, energy saving, consumption reduction, no three wastes , stable operation, reliable operation and convenient maintenance. The double-roller granulation machines have wide adaptability, suitable for the granulation of various raw materials such as compound fertilizer, medicine, chemical industry, feed, etc., and the product granulation rate is high.
Using characteristics of the roller extrusion granulator:
-
The double-roller extrusion granulator has a particularly good granulation effect on ammonium bicarbonate, ammonium chloride, monoammonium phosphate, etc. The pelletizing rate can reach 85%, without drying, less investment and quick return.
-
The double-roller extrusion granulator has no drying process, granulating at room temperature, one-time molding, low investment, quick results, and good economic benefits.
-
Small power, reliable operation, no three wastes, stable operation, convenient maintenance, reasonable process layout, advanced technology, and low production cost.
-
The roller extrusion granulator has a wide adaptability of raw materials. It can be used for the granulation of various raw materials such as compound fertilizer, medicine, chemical industry, feed, coal, metallurgy, etc., and can produce various concentrations and types (including organic fertilizer, inorganic fertilizer, biological fertilizer, magnetic fertilizer, etc.) compound fertilizer.
The working principle of the roller extrusion granulator:
This series of roller extrusion granulation is an 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 synchronized with the driven shaft through the split gear, and work in opposite directions. The materials are added from the hopper, formed by rollers, demoulded and pelletized, and passed through a pair of chains to be conveyed to the crushing screen studio, where the finished product particles (balls) are screened and separated, and then the returned materials are mixed with the new materials. Perform granulation. With the continuous rotation of the motor and the continuous entry of materials, mass production can be realized.
Common problems of roller extrusion granulator:
When producing fertilizers with roller extrusion granulator equipment, it is necessary to pay attention to the requirements for the production of granules. Irregularities are also acceptable. There is also the problem of granule hardness. If it is too soft, there is no way to transport it over long distances. In the production of fertilizers, it is necessary to produce according to the crushing condition of the material and the water content. If the material cannot meet the production requirements, the production cannot be carried out, because this will cause the pelleting rate of the particles to decrease, and it will not be able to come for sieving.
