The impact crusher mainly deals with materials with compressive strength below 350Mpa, such as limestone, gypsum, concrete, etc. Different types of impact crushers can be selected according to different materials. Taking the impact crushers of SMMVIK Machinery with a finished product output of 90-400T/H as a reference, how to select the appropriate models in the crusher market can be determined.
The PF impact crusher of SMMVIK Machinery uses high wear-resistant materials and a better crushing chamber, which makes the crusher excellent in performance. It is very suitable for crushing various soft and medium hard ores and for coarse crushing, medium crushing and fine crushing of materials. However, there are also the following requirements for material selection:
1. Fineness of materials after crushing. The fineness requirement is high, that is, the finer the crushed material is, the smaller the crushing capacity of the impact crusher is.
2. The humidity of the material. That is, when the water content in the material is large, the material is easy to adhere in the impact crusher, and also easy to block in the feeding process, resulting in reduced crushing capacity.
3. The viscosity of the material. That is, the greater the viscosity of the material, the easier it is to adhere.
4. The composition of the material. Before crushing, the more fine powder contained in the material, the more impact it will have on crushing, because these fine powders are easy to adhere and affect transportation, and those with a large amount of fine powder should be screened in advance.
The production capacity of this impact crusher is 90-400T/H, which is mainly used in metallurgy, mining, cement, chemical industry, refractory materials, ceramics and other industrial sectors. It is widely used in highway construction, water conservancy projects, construction crushed stone, machine-made sand processing and other fields. The impact crusher with 90-400T/H finished product output certainly has its unique characteristics and product advantages:
1. The world's manufacturing process is adopted, and better materials are selected. The product has strong universality. On the basis of not replacing other parts, the two chamber crushing equipment increases the grinding frame and reduces the secondary investment of users.
2. The bearing pedestal adopts an integral cast steel structure and a unique plate hammer locking device. The tightening torque is greater and safer, and the replacement of the plate hammer is simpler, more convenient and faster.
3. The improved adjustment device reduces the time of shutdown and maintenance. The lining plate is designed in a standardized way and has strong interchangeability. The type and inventory of spare parts for users are reduced, and the replacement is easier.
4. The rotor is analyzed to ensure stability and reliability. For heavy rotors, the finite element stress analysis and optimization design are carried out to obtain greater crushing ratio, crushing capacity and wear resistance.
5. The simple and practical locking device can tightly lock the back breaking shell I and shell II together. The device is simple and convenient to operate and saves the locking time.
6. Solid plates and wear-resistant parts reduce wear and improve production efficiency under various working conditions. Advanced processing technology and process are the basis of equipment performance.
SMMVIK Machinery PF impact crusher is a new type of crusher with small volume, large crushing ratio, low energy consumption and large production capacity. It is a very promising machine.
