    Hammer mill crusher is a kind of crusher is widely used in all walks of life, it can be used to sinter shale, coal gangue and broken process, mining, chemical, coal, and so on. Hammer crusher efficiency factors mainly include the following:

    (1) the material physical properties into hammer mill crusher

    The crushing principle of hammer crusher is a high speed impact crushing.Impact strength of brittle and hard material more than 10 times lower than the compressive strength, the characteristics of the hammer crusher is available material, increase efficiency of the broken.Crusher for soft materials such as soft shale crushing efficiency is low.

    (2) the moisture content of materials

    In the crusher in the process of high-speed rotation, the moisture in the material will become water vapor, make the fine powder adhesive on both sides of grate plate mesh, lining board, it will reduce the crushing cavity volume, the impact crushing effect is reduced, thereby reducing efficiency.

    (3) metal wear of hammer crusher machine

    The working efficiency of the hammer crusher is proportional to the rotor hammer linear velocity.Metal wear degree and the rotary speed of the secondary direct ratio.When wear without compensation or correction, turning diameter of hammer head is reduced, the linear velocity to drop, affect work efficiency.Metal wear also will cause the hammer head and back plate, screen plate, plate gap between increase, this will reduce the speed of the powder through the screen mesh, larger influence on crushing efficiency.

    (4) the partical of feeding materials into hammer mill crusher

    Large piece of material into the crusher, will extend the broken time, increase the proportion of coarse material, thereby reducing crushing efficiency.In production, when large materials ratio is higher, should consider to add the jaw crusher in the production line.

    In addition, they are professional cone crusher manufactures and ball mill suppliers, and stone crusher plant for sale, etc,. If you have any other question or have an interest on our product ,you can write to us:
