Hammer Mill Crusher
A hammer mill crusher consists of a rotor, hammers, liner plates, and a screen plate. Materials are crushed by the high-speed impact of the hammers and the rebound from the liner plates. The final output size is controlled by the screen plate at the bottom.
- Applicable materials
Effective for materials of medium to low hardness, such as limestone, coal, gypsum, and various ores.
- High crushing ratio
Can achieve a crushing ratio of 10-25mm, allowing for a single pass to a finer particle size.
- Easy maintenance
Features a simple structure that's easy to maintain. However, wear parts like the alloy hammers and screen plates require regular replacement.
- Adjustable output
The final particle size can be adjusted by changing the gap of the screen plate.
Hammer mills are used in compound fertilizer production for crushing materials like ammonium phosphate. They are suitable for both coarse and fine particle operations.

The standard shell material is Q235 steel, with customizable options for stainless steel or stainless steel liners for contact surfaces. Hammers are made from alloy steel.
