HT-SMP series wet coal crusher is mainly used for coarse, medium, and fine crushing of brittle materials with a moisture content of around 30%, such as coal, coal gangue, coke, limestone, etc. The crushing method is impact-splitting, and the compressive strength of the materials to be crushed ranges between 800–1500 kg/cm².
The machine features a rational design and compact structure, making it widely used in industries such as coal, metallurgy, building materials, and mining. It complies with national standards.
Working Principle and Structural Features:
The SMP Series Wet Coal Crusher mainly consists of the body, rotor system, swing hammers, movable screen grate system, transmission device, and discharge section. Key components are mounted on the body. During operation, materials are gathered in the crushing chamber and continuously impacted by high-speed hammers to achieve crushing.
The rotor system, composed of the main shaft, discs, and hammers, serves as the primary crushing mechanism. When the motor drives the rotor to rotate at high speed via a belt pulley, the hammers generate intense splitting force. Materials entering the crushing chamber through the feed inlet are shattered by the hammers to meet the crushing requirements.
For materials with certain moisture content, they first pass through the movable screen grate system for preliminary screening before entering the crushing chamber. Wet fine particles and small granules are directly discharged into the collection bin after screening, while larger particles are crushed and then fall into the collection bin through the grate plate. Productivity is proportional to the discharge particle size.
