Details

A claw crusher is a size reduction machine that uses high-speed rotating claw-shaped blades. The rotor drives multiple claws or blades intermeshing with fixed stationary parts, creating a powerful crushing action on materials entering the chamber. This design is particularly effective for processing medium-hardness, brittle, fibrous, or elastic materials. The equipment typically features adjustable screen meshes to control output particle size. Its robust construction ensures stable operation, low failure rate, and long service life across various industrial applications.

Core Advantages

High crushing efficiency with impact, shearing, and grinding composite action

Adjustable output particle size for flexible process matching

Simple structure with reliable operation and easy maintenance

Anti-clogging design prevents material wrapping on the rotor

Durable claw blades made from high-performance alloy steel with extended wear life

Self-cleaning action reduces unplanned downtime for jam clearing

Product Features

This claw crusher features high-speed rotating claw blades or toothed discs for composite crushing action, adjustable screen mesh for particle size control from 20 to 200 mesh, robust Q345B structural steel construction, surface-hardened key transmission components, IE3 energy-efficient motor as standard, and a self-cleaning rotor design that prevents material wrapping and residue buildup.

Product Applications

Widely used for medium to fine grinding of premixes, chemical fillers, plastics, rubber, fiber, paper, and low hardness materials in feed processing, pharmaceutical, chemical, food, recycling, mining, cement, and building materials industries.

Precautions

Install the crusher on a stable, vibration-damped foundation with proper alignment . Run idling for 2-3 minutes before feeding material. Maintain uniform feed rate to prevent choking and avoid prolonged overload operation . Inspect claws and rotor for wear regularly; check belt tension and bearing lubrication frequently. Shut down immediately upon detecting abnormal vibration, noise, or excessive temperature.

FAQ

Q: What types of materials can a claw crusher process?

A: Claw crushers can process a wide range of materials including grains, maize, straw, wood, traditional Chinese medicine, chemical fillers, plastics (rigid and flexible), rubber, fiber, paper, and low to medium hardness brittle materials .

Q: How do I control the output particle size?

A: Output particle size is controlled by changing the screen mesh installed at the discharge end. The adjustable range is typically from 20 to 200 mesh, allowing flexible matching to different process requirements .

Q: What maintenance does a claw crusher require?

A: Regular maintenance includes inspecting claw blades for wear, checking bearing lubrication, verifying belt tension, cleaning the crushing chamber, and replacing worn screens or blades as needed. The durable alloy steel blades typically last 1,200-1,800 hours of continuous use.
