Mobile Hammer Crusher

The mobile hammer crusher station utilizes a crawler carrier, with a vibrating feeder, hammer crusher, power system, control system, and belt conveyor mounted on the frame. Also known as an integrated mobile hammer crusher, it eliminates the need for foundation and steel frame construction required by traditional fixed aggregate production lines. It features a compact footprint, flexible relocation capabilities, adaptability to diverse terrain conditions, and low daily maintenance costs. The main unit employs a one-step hammer crusher with high hourly output and adjustable discharge particle size, meeting diverse user requirements.

Technical Specifications

Working Principle

The core of the mobile hammer crusher lies in high-speed impact crushing. The rotor drives the hammers to repeatedly strike, impact, and grind the material, producing finished products that meet the required particle size. The entire process consists of four steps:

1. Material Feeding: Upon startup, the vibrating feeder uniformly conveys material into the crushing chamber. Adjustable feed rates prevent material buildup at the inlet and avoid overload due to excessive feeding speed.

2. High-Speed Impact Crushing: Upon entering the crushing chamber, materials immediately interact with the rapidly rotating rotor. The rotor-mounted hammers generate immense impact force through high-speed rotation, directly acting on material surfaces to achieve primary fragmentation. Crushed particles then strike the impact liner on the chamber wall at high velocity, undergoing secondary impact for further reduction.

3. Grinding and Particle Size Control: Material smaller than the preset screen plate gaps passes directly through to become compliant finished product, transported by the integrated conveyor belt to designated locations. Material larger than the screen gaps is intercepted on the screen surface and cannot be directly discharged. This undersized material continues to undergo repeated hammer impact and grinding until its particle size reduces to meet the screen aperture requirements, at which point it passes through the screen for discharge.

4. Finished Product Conveyance and Environmental Treatment: Qualified finished materials meeting particle size standards are precisely conveyed via the equipment's integrated conveyor belt to predetermined target locations for subsequent transfer or direct use. Higher-end models additionally incorporate specialized dust collection systems to efficiently capture and process dust generated during crushing operations. This effectively minimizes dust dispersion impacts on the surrounding environment while enhancing workplace cleanliness.
