Impact Crusher

The impact crusher is used for the secondary crusher in the crushing plan.Due to the advantages of high capacity, energy saving, well-shaped and high comprehensive efficiency, it is widely used in mining.

Compared with the jaw crusher, impact crusher is used as the secondary crusher. It can crush all kinds of coarse, medium and fine materials whose feed particle size doesn’t exceed 500mm and compressive strength doesn’t exceed 350MPa. The impact crusher designed by the FTM machinery company can shape particle better.

Brief Introduction to Impact Crusher

Impact crusher is the machine of using the impact not the pressure to reduce the size of the raw material. FTM company introduced foreign advantaged technology to produce a kind of new impact crusher with no tension and cracks,special structure, little dust and cube finished products. It is equipped with the motor whose power is 6P 132KW and can meet the demands of many customers.

Features of the impact crusher

1.Large crushing ratio and high productivity. The materials can be fully crushed in the deep cavity, which has enlarged the crushing ratio and improved the productivity.

2. Wear-resistant and long service life. fragile parts is made of high strength wear resistant material. The gap between counterattack and hammer can be adjusted to reduce the wearing on the hammer. Besides, it is also equipped with safety devices to improve the life of the impact crusher overall.

3.Strong adaptability to materials. Various of rocks can be well shaped through the impact crusher. It can also provide the fine material for the grinding equipment. Therefor, the impact crusher is popular with the mining industry.

4.Well-shaped products. The impact crusher can shape fro its raw material, which is the unique feature that the cone crusher doesn’t have. It can also be used as the sand maker for some plan with low requirement on the size of sand.

5.Flexible configuration and wide application. The impact crusher can be used on the fixed sandstone production line or a mobile crusher unit. It’s suitable for some factories that has small scale or operates flexibly.

Factors that affect productivity

1.Quality of the equipment. The quality of machine itself is a key factor affecting the production capacity. Its quality directly affects the working capacity of the machine. A machine with good performance is stable in the process of operation and will not go wrong.

2.Performance of material. The performance of material also has a great influence on the capacity of products.

Impact crusher can break the stone below 350MPa, is suitable for crushing medium hardness stones, so impact crusher is is not recommended to crush the stones with higher hardness. Otherwise, the crusher will be damaged and the capacity of product will be reduced.

3.Operating procedures. In addition to external factors such as equipment and materials, human factors are also important.

Avoid the Abnormal phenomenon that bearing is hot or damaged, and impact crusher vibrates abnormally , workers should operate the machine according to the specification and inspect and maintain from time to time.

Working principle of the impact crusher

The rotor rotates at high speed under the driving of the motor. Then, the material collides with the plate hammer on the rotor, and is broken by high-speed impact from the plate hammer.

The broken material is rebounded to the liner and broken again. At last the broken material is discharged. Adjusting the gap between the counter frame and rotor can change the size and shape of the material.

Applied material

Because of wearable parts for the impact crusher, there are some limitation on the material with high hardness. It can process the coarse, medium and materials such as limestone, feldspar, calcite, talc, barite, rare earth, clay, kaolin, dolomite, kaolin, gypsum, graphite, etc.

Application of the impact crusher

Capacity: 160t/h. Sand making line for the limestone(Highway stone production base), 160t/h

The project was built by a company in Indonesia for limestone processing, and the finished aggregate is used for local highways. This production line is the classic configuration of our company: jaw crusher, impact crusher, sand maker. Its high production capacity, large output, well-shaped products, providing high quality stone for the construction of highway.

Capacity: 300t/h. We use the jaw crusher and impact crusher to process the calcite. The customer is very for its productivity and had plan to purchase another one to expand production scale. Capacity: 300t/h
