Crusher Features
Grinding Structure
A high-speed rotating impeller blade works in conjunction with a fixed blade to crush materials through impact and shear grinding. The relative motion of the movable and fixed toothed discs combines the impact, friction, and self-impact between the teeth and the material to enhance grinding fineness.
Cooling System
A strong airflow is generated inside the grinding chamber during operation, carrying away heat together with the finished product through the screen. This prevents the impact of high temperatures on heat-sensitive materials and helps extend the service life of the equipment.
Automatic Discharge
The crushed material is automatically discharged into a collection bag by centrifugal force, eliminating the need for manual discharge, reducing labor costs and preventing secondary contamination.
Dimensions
Overall dimensions (650 x 550 x 1200 mm), weight: 250 kg. It occupies a small footprint and can be integrated into various production line layouts.

Advantages of Coffee Bean Crushers
Energy Saving and Cost Reduction
A high spindle speed of 3800 rpm and an optimized grinding structure improve grinding efficiency. This also increases material utilization, reduces waste, and lowers production costs.
Adjustable Fineness
The grinding fineness can be adjusted from 20 to 120 mesh by replacing the screen. Whether for coarse or fine grinding, it can meet the diverse grinding needs of various industries, including chemicals, pharmaceuticals, and food.
Compliant with Standards
The entire machine is designed according to GMP standards and constructed entirely of stainless steel. This ensures dust-free production and ensures material cleanliness. It is particularly suitable for industries with stringent hygiene requirements, such as pharmaceuticals and food.
Reliable Performance
The equipment’s core technology and processes have reached internationally advanced levels. It offers stable and durable operation, minimizing production downtime caused by equipment failures.


Working Principle of a Coffee Bean Grinder
Grinding Stage
The high-speed rotating blades of the impeller and the fixed blades move rapidly relative to each other, impacting, shearing, and grinding the material. The relative rotation of the movable and fixed toothed discs further pulverizes the material through the impact and friction of the toothed discs, as well as the impact between the materials themselves. This dual action ensures effective pulverization.
Heat Dissipation and Discharge Stage
During the pulverization process, airflow is generated within the machine chamber, carrying the heat generated by the pulverization along with the material through the screen. The finished product is driven by centrifugal force during the rotation process. Finally, the finished product is automatically collected in a collection bag.
