The roller squeezing granulator is an efficient granulation equipment, mainly composed of the following key components:

Pressure roller: The main component of a roll extrusion granulator, usually composed of two relatively rotating pressure rollers, with specific groove designs on the surface of the pressure rollers, used for extrusion molding of materials.

Feeding device: responsible for evenly feeding raw materials between pressure rollers to ensure continuous and stable feeding.

Transmission system: including motor, reducer, coupling, etc., used to drive the rotation of the pressure roller.

Adjustment mechanism: used to adjust the gap between the pressure rollers to control the size and shape of particles.

Cutting device: located behind the pressure roller, used to cut the extruded strip material into particles of the required length. It can be a fixed blade or a rotating blade.

Drying system: Newly formed wet particles need to be reduced in moisture content through the drying system, usually including a dryer and heat source equipment.

Screening and grading device: used to separate particles that meet the standards and unqualified particles that require rework.

Cooling system: The dried particles need to be cooled to ensure their stability during storage and transportation.

Packaging system: including automatic weighing and packaging equipment, used to package finished granular fertilizers.

Control system: Modern roller extrusion granulators are usually equipped with PLC or microcomputer control systems to achieve automatic control of the entire granulation process.

Support and framework: The supporting structure of the entire machine ensures its stability and durability.

Dust removal system: Dust may be generated during the granulation process, and the dust removal system is used to collect dust and reduce environmental pollution.

Lubrication system: Ensure lubrication of pressure rollers and other moving parts, reduce wear, and extend equipment life.

Safety protection devices, such as emergency stop buttons, protective covers, etc., ensure the safety of operators.

The collaborative work of these components of the roller extrusion granulator ensures the efficiency and stability of the granulation process. According to different production needs, the specific configuration of roller extrusion granulators may vary, but the above listed are the basic components common to most roller extrusion granulators.
