Overview
Breaking Lumps by Chain Impact
In a chain crusher, chains attached to one or more rotors spinning inside the housing strike the material fed from above and break up lumps and friable pieces. The material is reduced as it passes through the chain zone and leaves at the bottom.
The flexible chains spread the impact, making it possible to crush caked or semi-moist products. Chain crushers are therefore used in fertilizer and compost lines for lump breaking and size reduction of friable products.
Product size depends on rotor speed, number and length of chains, internal clearance and material behaviour. For very hard minerals, jaw or impact crushers may be more suitable.
01Process Flow
Chain Crusher Material Flow
The diagram shows the typical flow in which the chain crusher takes lumpy material from above, breaks it by chain impact and discharges it at the bottom.
Scroll horizontally to view the full diagram.
Material line
- 1
Material feeding: Lumpy or friable material enters through the top inlet.
- 2
Chain impact: Rotating chains strike and break the lumps.
- 3
Passage through the housing: Material is reduced as it passes the chain zone.
- 4
Bottom discharge: Crushed product goes to screening or the next process.
A chain crusher usually works with screening; oversize product can be returned to the crusher after screening.

05FAQ
Chain Crusher FAQ
How does a chain crusher work?
Chains on a rotor spinning inside the housing strike material fed from above and break up lumps and friable pieces; product leaves at the bottom.
Which products suit a chain crusher?
Lumpy, friable and semi-moist products such as fertilizer and compost. For very hard minerals, jaw or impact crushers are assessed.
Do moist products cause problems?
Moist and sticky products can build up in the housing. Housing design and cleaning access are chosen according to moisture behaviour.
Which parts wear?
Chains and internal housing liners; the chains are replaceable.
What information is needed for a quotation?
Product type, moisture and stickiness, lump size, target size and hourly capacity.
