The sealed hammer crushing and splitting machine is mainly used for medium and fine crushing of raw materials. Such as coal, coke, limestone, pyrite, phosphate rock, coal gangue, and various other materials that need to be crushed. Its crushing method is chopping. The maximum particle size of the crushed material should be less than 10-60 mm of the feed opening size of the selected machine model.

The machine is reasonably designed and has a simple structure. It is widely used in metallurgy, building materials, laboratory testing, and other industries. The fully sealed design ensures no pollution, making it the preferred crushing machine for the laboratory testing industry. The product meets national standards.

‌Operating Principle and Structural Characteristics‌:

The fully sealed hammer crusher mainly consists of a machine body, rotor system, hammer heads, screening grate, transmission device, and power part. The machine body adopts two structural forms, one is an integral casting, and the other is welded with high-quality steel plates. It mainly gathers the material inside the body for the hammer heads to strike, achieving the purpose of crushing.

The rotor is assembled from a spindle, disk, hammer heads, etc. When the motor drives the rotor through the pulley, the hammer heads rotate at high speed, generating strong impact force. The material enters the striking zone of the rotor hammer heads and is crushed. When the crushed material reaches the required particle size, it falls into the material bin. The particle size is controlled by the size of the screening grate. The output volume is also directly proportional to the size of the grate holes.

The small-sized sealed hammer crusher is also equipped with a manually controlled feed gate on the material inlet hopper to avoid dust generated by high-speed rotation. To enhance the impacting force, large and medium-sized hammer crushers are also equipped with flywheels for energy storage.
