Fertilizer Crushing Equipment
-
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.
Effective for materials of medium to low hardness, such as limestone, coal, gypsum, and various ores.
Can achieve a crushing ratio of 10-25mm, allowing for a single pass to a finer particle size.
Features a simple structure that's easy to maintain. However, wear parts like the alloy hammers and screen plates require regular replacement.
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.

The various raw materials of fertilizers go through the entire process of feeding, crushing, mixing, conveying, granulation, drying, cooling, screening, coating, and packaging.
When dealing with materials that are harder and more difficult to crush, a hammer mill is an excellent choice. It’s particularly effective for jobs that require a large crushing ratio in a single pass.
The cage mill crusher is an excellent choice for crushing limestone. It features multiple layers of concentrically arranged steel cage bars. Material is repeatedly impacted and crushed through friction as it moves between these high-speed rotating bars. This makes it ideal for medium to low-hardness, brittle materials, producing a uniform particle size with minimal over-grinding.
Our lump breaker is perfectly suited for this. It features high wear-resistant alloy components and a heavy-duty welded frame, paired with hydraulic overload protection for superior impact resistance and anti-deformation. Its vibration-damping design reduces loss from vibration, ensuring stability and long life even in harsh working conditions. This crushing machine is highly tolerant of incoming material, capable of directly handling large blocks of 1-1.5 meters without pre-crushing, meeting the demands of large-scale production.
