Secondary Impact Crusher

In general, this type of crusher is preferred to obtain aggregates in the dimensions needed for asphalt and concrete production. For these purposes, cubic aggregate is preferred because the angular and rough surface has high bonding properties. Impact crushers have the ability to obtain cubic aggregates without weak or crack points.

High size reduction ratio

Secondary impact crushers are among the most economical choices for soft and medium hard materials such as limestone, limestone and dolomite, as they are in a design that can be preferred for crushing hard materials such as stream material and basalt.

They take place in the secondary stage in crushing and screening processes. It is responsible for bringing the material brought to a certain size in the primary crusher to the desired product size by subjecting it to the size reduction process for the second time. After this stage comes the classification stage.

Generally, the secondary impact crusher is placed after the jaw crusher as it can shrink the feed material up to 0-25 mm dimensions. The feed material breaks down at weak points, and then only a solid piece of stone remains. For this reason, they are the most suitable stone types with medium hardness such as limestone.

ADVANTAGES

- Continuous production of cubic material even in the event of wear of parts;
- High size reduction capacity;
- Robust body;
- High efficiency with low energy consumption;
- Easy maintenance and operation;
- Low operating cost.

HOW DOES THE SECONDARY IMPACT CRUSHER WORK?

The crushing chamber of the secondary impact crusher is designed as three separate zones.

With the hammers on the rotor rotating at high speed, it transfers the kinetic energy it has to the fed material by impact. With this impact, the material is thrown into the pendulums in the first zone of the crushing chamber. In this area, pendulums absorb the kinetic energy of the materials. While the kinetic energy is transferred to the pendulums, the material is crumbled thanks to the high pressure formed on the inner walls. This movement between the rotor and the pendulum is repeated until the broken material passes through the gap between the pendulum liner and the rotor paddle.

When a stone reaches the desired dimensions, it passes to the second zone and undergoes crushing. Thus, it is reduced to smaller sizes. In the third zone, the final crushing takes place, which allows the material to be reduced to the smallest possible dimensions.
