Dry Type Granulation Method Double Roller Press Granulating Machine

Introduction to roller press granulating machine

Roller press granulator is the key equipment of compound fertilizer granulation, It is a kind of extrusion machine, adopts physical strength to condense and granulate the dry materials. The double roller extrusion granulator can work under normal temperature, but yields high granulation ratio.

Specifications of roller press granulating machine

Working principle of roller press granulating machine

1.Firstly, you need put the mixed fertilizer materials on the belt conveyor, then the powdery raw material will enter the double roller press granulator.

2.The material is forced between the two rollers below for extrusion, and the two rollers rotate relative to each other.

3.Under the strong extrusion pressure, the delivered materials become a cake shape with a stick mold, and the cake shape bar enters the crushing workshop.

4.The crushed materials are broken by the broken axis, and are screened through the screen below the crushing chamber.

5.Qualified particles are sent to the outside through the air. And the sifted powder material will be sent back to the raw material warehouse for the second roll.

Features of roller press granulating machine

1. The roller press granulator is without drying process, room temperature granulation, a molding, less investment, quick effect, and good economic returns.

2. Compound fertilizer on roller extruding and granulating machine power of small reliable operation, no waste discharge, stable operation, convenient maintenance, process layout is reasonable, advanced technology, low production cost.

Advantages of roller press granulating machine

1. Wide application to all kinds of raw materials. You can not only use double roller process machine in fertilizer pellets producing. But it is perfectly used to make pellets in medicine, chemical, metallurgy, coal and fodder.

2. Less investment. Extrusion granulator machine making fertilizer pellets in room temperature. Thus, you do not buy fertilizer dryer and cooler machine.

3. No waste pollution discharging. Our roller press granulating machine adopts electricity as the main power. Therefore, there will be less pollution to the environment.

Applications of roller press granulating machine

Double roller press granulating machine can be widely used in many businesses. It can granulate pellets with a number of different kinds of raw materials. Here are some of the applications for you to refer to.

1. Compound fertilizer granulation.

2. Solid chemicals granulation.

3. Pharmaceutical granulation.
