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.

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.
