A 원뿔형 크러셔 ~의 일종입니다. secondary or tertiary crushing equipment used in mining, quarrying, and aggregate production to reduce large rocks into smaller, more uniform-sized pieces.
It is called a 원뿔형 크러셔 because the crushing mechanism consists of a moving cone-shaped mantle inside a fixed concave bowl liner. The rock is crushed by compression between these two cone-shaped surfaces.
Cone crushers are widely used for crushing:
They are especially suitable for producing fine and medium-sized crushed stone with good shape.
A typical cone crusher consists of the following parts:
그 mantle is the wear-resistant liner mounted on the moving cone.
기능:
The mantle gradually wears out and must be replaced.
그 concave is the stationary wear liner surrounding the mantle.
기능:
The gap between mantle and concave controls the discharge size.
The main shaft supports the moving cone.
기능:
The eccentric mechanism is the heart of the cone crusher.
It creates an off-center rotation of the main shaft, causing the mantle to move in a circular path.
Includes:
It provides power to rotate the eccentric assembly.
Modern cone crushers use hydraulic systems for:
The crushing process happens through compression crushing.
The working steps are:
Large rocks enter through the top opening of the crusher.
예시:
The material falls into the crushing chamber.
모터가 편심축을 회전시킵니다.
The eccentric movement causes the mantle to:
The mantle does not rotate like a normal wheel; it moves in a gyratory circular motion.
When the mantle approaches the concave:
The rock is crushed mainly by:
When the mantle moves away:
The discharge opening size controls the final product size.
