rolling stone hammer crusher

A Rolling Stone Hammer Crusher is a type of impact crusher that uses rotating hammers to break down materials through impact and shear forces. It is commonly used in mining, cement, coal, metallurgy, and construction industries for crushing medium-hard to brittle materials like limestone, coal, gypsum, and ore.

rolling stone hammer crusher Key Features:
1. Rotating Hammers – The crusher has a rotor with swinging or fixed hammers that strike the material as it enters the crushing chamber.
2. High-Speed Impact – The hammers rotate at high speed (typically 500–3000 RPM), delivering strong impact forces to shatter the material.
3. Adjustable Discharge Grate – Allows control over the final product size by adjusting the gap between the hammers and the grate.
4. Robust Construction – Made of wear-resistant materials (e.g., high manganese steel) to withstand abrasive materials.
5. Versatility – Can handle wet or sticky materials better than some other crushers.

rolling stone hammer crusher Working Principle:
1. Feeding – Material is fed into the crusher through a hopper.
2. Crushing – The rotating hammers strike the material, breaking it into smaller pieces against impact plates or grates.
3. Discharge – Crushed material exits through adjustable grates at the bottom.

Applications:
– Mining & Quarrying (coal, limestone, phosphate)
– Cement production
– Recycling (glass, construction waste)
– Chemical & Fertilizer industries

Advantages:
– High reduction ratio
– Simple structure & easy maintenance
– Good for both dry and slightly wet materials

Disadvantages:
– Higher wear on hammers & liners (requires frequent replacement)
– Generates more fines than compression crushers
– Not ideal for very hard or abrasive rocks (e.g., granite)
