Product Overview
The PCD Hammer Crusher is designed to crush various medium-hard materials with weak corrosion resistance. The compressive strength of the materials should not exceed 100MPa, and the moisture content should be less than 15%. It is suitable for processing coal gangue, slag, waste board scraps, and materials with fibrous structures, high elasticity, and toughness, such as wood scraps, paper, or asbestos cement waste for asbestos fiber recovery. Additionally, the hammer crusher can be utilized not only in crushing and sand-making production lines but also as a replacement for cone crushers in mineral processing lines. It is an essential supporting equipment in precast concrete production lines such as the precast concrete wall panel extrusion line.
Working Principle
The core component of the hammer crusher is a rotor equipped with hammers (also called hammerheads). The rotor consists of a main shaft, discs, pin shafts, and hammers. The motor drives the rotor to rotate at high speed within the crushing chamber. Materials are fed into the machine through the upper feed inlet and are crushed by the impact, collision, shearing, and grinding forces of the high-speed rotating hammers. A sieve plate is installed at the lower part of the rotor. Particles smaller than the sieve aperture pass through the sieve plate, while larger particles are retained for further crushing and grinding until they meet the required size and are discharged.
Product Features
- Large feed inlet and high crushing chamber—ideal for hard, bulky materials with minimal stone powder output.
- Adjustable gap between the counterattack plate and hammer—enables precise control over discharge particle size and ensures excellent particle shape.
- Compact structure, robust rigidity, and high rotational inertia of the rotor—enhances operational stability and efficiency.
- High-chromium steel hammers—offer superior impact resistance, wear resistance, and powerful crushing force.
- Easy maintenance—cost-effective and reliable performance.
- Low wear on crushing components—extends service life and reduces downtime.
Applications
With advantages such as a high crushing ratio (10–40), uniform discharge particle size, minimal over-crushing, cost-effective design, and easy maintenance, the hammer crusher is widely applied in industries including building materials, precast factory,coal, chemical engineering, and metallurgy.
