Commonly used crushing machinery classifications are: Jaw Crusher, impact crusher, hammer crusher, compound crusher, cone crusher, roller crusher, etc.

1. THE ADVANTAGES OF VARIOUS
TYPES OF CRUSHERS
Commonly used crushing machinery classifications are: Jaw Crusher, impact crusher,
hammer crusher, compound crusher, cone crusher, roller crusher, etc. They have different
advantages and are common crushing equipment in coarse aggregate production lines. So,
do you know the characteristics and differences of these crushers? The editor of Zhongyuan
summarized the comparison of various types of crushers for everyone, let’s take a look at it
together.
1. Jaw Crusher
Jaw Crusher is a widely used crushing equipment and one of the most primitive crushing
machinery and equipment. There are many types of Jaw Crusher, among which the
compound pendulum jaw crusher and its improved type are the most used, supporting the
coarse crushing operation of the mine.
①
Structure: It is composed of frame, eccentric shaft, large pulley, flywheel, movable jaw, side
guard plate, toggle plate, toggle plate rear seat, clearance adjustment screw, return spring,
fixed jaw plate and movable jaw plate, etc. The toggle plate also plays a role in insurance.
②
Principle: The motor drives the belt and pulley, and the movable jaw moves up and down
through the eccentric shaft. When the movable jaw rises, the angle between the toggle plate
and the movable jaw becomes larger, thereby pushing the movable jaw plate to approach
the fixed jaw plate, and the material is squeezed Multiple crushing such as, rubbing, and
grinding; when the moving jaw moves downward, the angle between the toggle plate and
the moving jaw becomes smaller, and the moving jaw plate leaves the fixed jaw plate under

2. the action of the pull rod and spring, and the crushed material exits the lower mouth of the
crushing cavity. Discharge, as the motor continuously rotates and breaks the mobile jaw for
periodic crushing and discharging, realizing mass production.
③
Advantages: The crushing cavity is deep and there is no dead zone, which improves the
feeding capacity and output; the crushing ratio is large, suitable for coarse crushing; the
gasket-type discharge opening adjustment device is stable and convenient, and the
adjustment range is large, which increases the flexibility of the equipment; The lubrication
system is safe and stable, the parts are easy to replace and replace, the maintenance workload
workload is small; the structure is simple, the work is stable, and the investment cost is
extremely low.......
