01 / Equipment overview
High-speed impact crushing for secondary and fine reduction
A hammer crusher is used where prepared feed requires further impact crushing and size reduction before screening, classification or downstream separation.
The BREM Hammer Crusher is an impact-type crushing machine built around a housing, rotor, wear-resistant hammer heads, impact liners and a screen plate. Material enters from the upper feed opening and is repeatedly impacted, sheared and ground by the high-speed rotor until particles are small enough to pass through the screen. The grate or screen opening can be adjusted or customized to meet different output-size requirements. It is mainly used for medium and fine crushing of suitable lithium battery, printed circuit board, can, aluminum residue and other brittle or crushable recycling feedstock.
Feed material should be evaluated for composition, maximum size, required capacity, target output, moisture, contamination and downstream separation requirements. Feed and output dimensions are customized according to project requirements.
02 / Operating Principle
How the Hammer Crusher Works
Material enters through the upper feed hopper and falls into the crushing chamber. The high-speed rotor drives the hammers to strike and break the material repeatedly. Oversized particles remain in the chamber for further impact, while sufficiently reduced material passes through the lower grate and exits through the discharge opening.
02
Impact Crushing
The high-speed rotor drives the hammers to strike and throw the material against the chamber liners, producing repeated impact breakage.
03
Screening & Size Control
Material small enough to pass through the grate openings moves downward, while oversized particles remain inside for further crushing.
04
Discharge
Crushed material passing through the grate falls into the lower discharge section and exits for collection or downstream processing.
High-Speed Impact
Grate-Controlled Sizing
Continuous Discharge

Engineering proof
The high-speed rotor carries wear-resistant hammer heads that repeatedly impact and shear the feed. The lower screen controls discharge, while coarse particles remain in the chamber for further impact and grinding. A sealed housing helps reduce dust leakage from the crushing area.

09 / Equipment FAQ
Common selection questions
How is the correct hammer crusher model selected?
Model selection should consider material type, feed size, required throughput, target output size, operating hours and downstream process. The supplied models cover approximately 300–1300 kg/h with 30–55 kW motor power.
Can the discharge size be adjusted?
Yes. The source states that the grate or screen gap can be adjusted according to customer requirements, allowing the discharge size to be changed for different crushing duties.
What happens to particles that are larger than the screen opening?
Oversize particles are retained on the screen plate and continue to receive hammer impact and grinding until they are small enough to pass through the screen.
How does the machine reduce dust leakage?
The crusher housing uses a sealed design intended to reduce dust pollution in the crushing area and minimize ash or dust leakage from the machine body.
What materials are typically suitable?
The supplied application information includes lithium battery materials, printed circuit boards, cans and aluminum residues, plus other compatible medium-hard or brittle recycling materials.
What routine maintenance should be checked?
Routine checks should include hammer wear, rotor condition, screen wear or blockage, liner condition, fasteners, bearings, lubrication, dust seals and abnormal vibration or noise.
