Pebble Stone Crushing Equipment Horizontal Shaft Impact Crusher Wear Resistant

PF1214 Rock Stone Impact Crusher With 3 Impacts Cavities For Limestone Plant Introduction:

PF series impact crusher are designed for crushing ores and rocks with particle sizes less than 350mm and compression strength no more than 350MPa. It has a feature of big crushing ratio, high-efficiency crushing, cubic shape, selectable crushing and etc. It is suitable for crushing different compression strength of rocks in mining, cement and concrete industries. And it is widely used to produce fine stones for constructions of highway, airport, building, etc.

PF Series Impact Crusher Parameters:

PF1214 Rock Stone Impact Crusher With 3 Impacts Cavities For Limestone Plant Working Principle:

PF series impact crusher machine crushes materials with impact force. When the materials enter the blow bar area, they are crushed due to the high speed impact of the blow bar and are thrown to the impact plates on the rotor for secondary crush. Then the materials will be shot back to the blow bar again for the third crush. This process repeats until the materials are crushed to the required size and discharged from the lower part of the machine.

The size and shape of the finished powder can be changed by adjusting the gap between the impact rack and rotor support. The machine employs self weigh security device in its back frame.

When other objects enter the impact cavity, they will be forced out of the mace by the impact rack in the front and back of the machine.

Stone Rock Breaker Impact Crusher with Blow Bar Main Structures:

The impact crusher includes a single rotor impact crusher and a double rotor impact crusher. The structure of the single-rotor impact crusher is relatively simple, and the material block is fed from the feed port. In order to prevent the material block from flying out during the crushing, a chain curtain is arranged in the feeding direction of the feed port. The feed block falls on the top of the stringer, and the small block falls through the quilting to the lower part of the casing, and the bulk material slides along the screen surface onto the rotor. A plate hammer having a certain height is fixedly mounted on the circumference of the rotor, and the rotor is rotated by the motor through the V-belt belt at a high speed. The block falling on the rotor is impacted by a high-speed rotating plate hammer. After obtaining kinetic energy, it hits the counter-attack plate at a high speed, and then bounces back from the counter-attack plate, and collides with the material thrown by the rotor in the crushing zone. The space formed by the strip screen, the rotor, the counterattack plate and the chain curtain is called the first impact zone; the space formed between the counterattack plate and the rotor is the second impact zone. After the material is crushed by mutual impact in the first impact zone, it then enters the second impact zone and is subjected to impact pulverization again. The broken material is discharged through the discharge port at the lower part of the casing.

One end of the counterattack is suspended from the casing by a live chain, and the other end is fixed by an adjusting bolt. When a large piece of material or a difficult-to-break object is caught between the rotor and the counter-attack plate, the counter-attack plate is subjected to a large pressure to cause a counterattack to move backward.
