Capacity: 3-500 m/ h. Input Size: 120-1020mm. Output Size: 10-300mm. 1. Introduction The Jaw Crusher is widely used in mining, building materials, chemical industry, metallurgy and so on. The Jaw Crusher is suitable for primary and secondary crushing all kinds of minerals and rocks with compressive strength less than 320 MPa. 2. Processed Materials Iron ore, copper ore, gold ore, manganese ore, river stone, gravel, granite, basalt, minerals, quartz, diabase, etc. Applications Mining, metallurgy, construction, highway, railroad, and water conservancy 3. Working principle The motor transmits through belt, drives the moving jaw to do periodic motion towards the fixed jaw by the eccentric shaft. The angle between toggle plate and moving jaw plate increases when mobile jaw moving. So the mobile jaw moves towards the fixed jaw. The stuff will be crushed in this process. The angle between toggle plate and moving jaw decreases when moving jaw moves down, the moving jaw moves leaves fixed jaw by pulling rod and spring, the final crushed stuff will be discharged from the outlet. 4. Advantages (1). Simple structure, easy maintenance; (2). High crushing ratio, even output granularity; (3). High reliability, low investment; (4). Low noise, less dust. All equipments are produced by the professional technicians of our own factory, with best price and high quality. We look forward to cooperating with you.
