PMS Hammer Mill


PMS Hammer Mill® is a machine that primarily uses impact forces to break down and reduce the particle size of dry materials. It is a popular choice for the fine grinding of materials and is capable of processing both wet and dry granulations and dispersing powder mixtures.

The particle size and throughput of the ground material are determined by several factors, including the rotor speed and the size of the screen used in the machine. The hammers are the primary impactors that strike the material, while the rotor speed determines the frequency and intensity of these impacts. The size of the screen used in the machine determines the size of the final product, as smaller screens produce finer particles while larger screens produce coarser particles.

Overall, this machine is a versatile machine that can be used in a variety of applications, including food processing, mineral processing, and chemical industries, among others, to break down and reduce the size of dry materials.



The feed material is presented into PMS HAMMER MILL® through adjustable-angle feeding tray or through feeding chute. Swinging blades are affixed to a high-speed rotor mounted in a chamber. The chamber is bounded on the bottom by an interchangeable screen through which the milled material must pass. The rapidly rotating hammers strike against the feed material, breaking it into smaller fragments, which are swept against the screen. Particles, that are small enough to pass through the screen, drop through the discharge chute into a collection container.


Type of hammer, rotor speed and size of the screen openings are important factors governing the particle size of the product. Flat-edge hammers are generally used for pulverizing and tend to create a large number of fines. Knife-edge hammers are generally used for chopping and sizing when fines are undesirable or when fibers and tissues must be severed. 


Product particle size varies for a given screen according to the rotor speed. The discharge product is actually smaller than the nominal dimensions of the screen opening. Finer particles are produced with a given grid at higher speeds.  


The driving is through belts and pulleys. The bearing and seal design in such a way that no contamination from driving unit would enter the processing chamber. The motor and mill assembly are mounted on a common baseplate which carries the ground product discharge chute and a rigid support frame, resulting a compact design configuration.
