In many fields or industries, crusher machines are necessary for dealing with the big size materials. In china, there are many manufacturers and suppliers of crusher machines, such as shanghai SBM company, a professional manufacturer and supplier of mining machines. There are many crusher machines in stone crushing plant for sale in China.
Crusher machines have many different types, such as jaw crushers, impact crushers, cone crushers and so on.All these different types have their characteristics in practice. Taken the jaw crusher as an example, jaw crusher is often used in breaking all kinds of ores in medium granularity, especially for large size materials. It is widely used in mining, smelting, building material, highway, railway, water conservancy and chemical industry, etc. Being broken material maximum compressive strength is 320 MPa.
Cone crusher is a kind of hydraulic crusher with advanced power, large crushing ratio, and high productivity. In the process of cone crusher work, motor through the driving device drives the eccentric set for rotating. Moving cone under the forced motion of eccentric shaft sleeve does rotary oscillation. Dynamic cone forms a crushing cavity with static cone section.The material are extruded, impacted and broken for many timesunder the force of dynamic and static cone plates. When dynamic cone leaves that section, the materials have been broken to the required size and they are discharged from the bottom of the cone cavity. To be broken material is sent into the cone crusherfrom the inlet.
Impact crusher is a new type of high efficiency crushing equipment. Its features are: small volume, simple structure, big crushing ratio, less energy consumption, large production capacity, uniform final product size, and selective crushing effect. It is a very promising device.Impact crusher plate hammer and impact plate is the chief drawback, which are particularly easy to wear and tear. When impact crusher breaks hard ores, the abrasion of plate and hammer is more serious. The plate and hammer often need to be changed regularly. At present due to the emergence of some wear-resisting material, has been applied in some metal concentrator.
In stone crushing plant, jaw crusher is usually used as the first stage crushing machines for the big materials crushing. The impact crusher or the cone crusher is used as the second stage crushing machines for the medium size materials. Clients can choose the crushing machines flexibly according to the stone crushing plant’s needs.
The material in crushermust meet the requirements ofbreakability. The material strength must be within the maximum intensity that crusher can handle. In addition, in the process of crushing, crushing cavity should prevent iron and other things that cannotbe broken into it. When mixed together after feeding material broken, there are all kinds of material with unevenstrength.Materialswith large strength will protect materials with small strength, reducing the broken probability of material with small strengthand improve the product granularity. And due to the intensity of the crushing cavity plate stress is not uniform;it can eventually lead to uneven worn plate, which can affect the normal work of the crusher. Therefore, in order to improve the working efficiency of the crusher, it should improve situation of spare parts of the equipment, and give full play to the function in the process of laminating crushing in broken.In the process of production, operator should try to ensure the requirements of uniformity of feeding material strength.
