Hammer mill

The hammer mills are ideal for coal and soft mineral crushing applications. They are high capacity hammer mills with high reduction rate. Since the grinding walls are arranged on both sides of the crusher, the direction of the rotor can be reversed for optimal usage of the beater heads and longer service life.

Hammer mill is for fine and medium crushing (Product size up to<5mm,Hard coal and lignite in coal processing and power plants (circulating fluidized bed),Limestone and gypsum rock,Other related soft to medium-hard minerals, as well as various types of salt and fertilizer.

Hammer Mill Application:

  • 1)Hammer mill is suitable for mid-hard and light erosive materials, whose pressure resistance strength is no more than 100Mpa and humidity lower than 15%, such as coal, salt, chalk, gypsum, blocks, limestone, etc.
  • 2)Hammer mill also used in crushing fiber structure, strong flexibility and tenacity of broken wood, paper or the waste of broken asbestos and cement to recycle asbestos fibres and so on.
  • 3)In addition, hammer crusher can be used not only in crushing production line, sand production line, but also can instead to be used in mineral processing production line.

Hammer mill advantages:

  • 1. It can once moldings, don't need a second fracture process. So it can cut the cost.
  • 2. It also can crush the wet stone. You can add water to reduce the dust pollution during crushing ,this way could protect workers health and keep a good environment.
  • 3. We adopt durable parts, especially the PCZ series heavy hammer crusher, which is more durable than the jaw crusher and impact crusher. We use the alloy hammer ,the cast steel parts to guarantee the function and its life.
  • 4. We have many types whose capacity ranges are form 50t/h to 800t/h to meet the clients’ requirement.
  • 5. The outlook design and the strengthened intrinsic quality make the performance to be more superior.

Operating principle of Hammer Mill:

In the hammer mill machine, the motor drives the rotor rotate at a high speed through the belt, and on the rotor there are series hammers. When the materials get into the working area of hammers, the rotating hammers with high rotation speed are crushing them, the products which are crushed to meet the required size can be discharged by the outlet and become the final products, the large size products are brought back to the crushing area by the hammers for being re-crushed until they reached the required size.
