Jaw crusher commonly known as jaw broken, also known as the tiger mouth. The moving jaw and the static jaw two jaws form a crushing chamber, simulating the movement of two jaws of an animal to complete the material crushing operation of the crusher. Widely used in mine smelting, building materials, roads, railways, water conservancy and chemical industries in a variety of ore and bulk materials crushing. The highest crushing material is 320Mpa
Common jaw crushers are available with double toggle and single toggle. The former moves jaw only for simple arc swing at work, so it is also called simple swing jaw crusher; the latter also makes up and down movement while swinging arc.
Domestic jaw crusher manufacturers vary greatly in technical level, a small number of manufacturers of products close to the advanced world level, while most manufacturers of products with the world advanced level gap. Jaw crusher rack a large proportion of the quality of the whole machine (casting rack accounted for 50%, welding rack accounted for 30%). Foreign jaw crusher is welding rack, and even moving jaw also uses welded structure. Jaw crusher welding rack is the development direction. Domestic jaw crusher rack structure design examples of many unreasonable, the reason is not according to the actual force of the crusher to place the stiffener
In recent years, with the increase in the proportion of open-pit mines and the adoption of large power shovels (excavators) and large-scale mining vehicles, the ore blocks transported to the crushing workshops in open-pit mines have reached 1.5-2.0 m. At the same time, The grade of ore is decreasing day by day. If it is necessary to maintain the original production capacity of ore dressing plant, the amount of ore ore to be mined and the amount of ore to be mined must be greatly increased. Therefore, the jaw crusher is being developed in a large scale. At present, the largest jaw crusher manufactured in foreign countries is: 3000 × 2100 mm (simplified figure), 1800 mm for lump ore, 1100 tons / hour, 2100 × 1670 mm (compound pendulum) When the discharge port is 355 mm, its production capacity is 3,000 tons / hour.
