HM Series Hammer mill

Excellent in industrial and laboratory applications

Hammer Mill

The hammer mill is suitable for milling and sizing products.

HM-300 has new design and technics which improve the efficiency and easy to clean and maintenance. Also support the inline/offline sterilization.

HM Series milling process

Hammer Mill


Ø Bigger active sieve surface lead to higher throughput and low temperature rise.

Ø The good design reduce the number of the moving parts. The connection of the tri-clamps assure an easy way to assemble and dismantle the milling chamber which assure the offline sterilization;

Ø This means: Quick and easy cleaning and maintenance and high operational availability at lower operating costs.

Hammer Mill

A. All tri-clamp assembled feeding device;

B. AT rotating cylinder;

C. The high speed rotor with both knife and hammer side;

D. The rotor and the sieve do not have mechanical contact;

E. High active opening sieve;

F. The milling head can be easily dismantled.


The product goes through the feeding valve which ensures a consistent product flow to the milling chamber. Then the product is impacted by the high speed rotor and then becomes smaller particles which goes down through a screen mounting below the rotor. Customer can adjust the rotor speed and screen size to achieve required particle size distribution.

HM Series hammer mill performance

Better performance

Ø HM-300 has bigger active screen opening, about 30% larger than the competitors;

Ø Higher throughput;

Ø The height of the machine is adjustable;

Ø The dead surface of the sieve is very small and there is therefore no danger of the product overheating
