THis article's copyright of Jaw crushers for stone crushing is belong to Suming.
General descriptionThis series have many advantages, such as big reduction ratio, even granularity, simple structure, reliable working condition, convenient repair and economic operation, which are widely used for mine, smelting, building material, road, railway, irrigation works, chemical and materials with compression strength no more than 320 Mpa.
The crusher machine is available as single toggle jaw crusher and double toggle jaw crusher. These variants are fabricated from heavy duty plate frames with reinforcing ribs on the surface. All the crusher parts are manufactured from special alloy that can withstand heavy draw. Manganese steel is the preferred material for both fixed and moving jaws. Heavy fly wheels facilitate smooth crushing of the mineral feed. Some double toggle jaw crushers may also feature hydraulic toggle adjusting mechanisms.
According to structural features, it can be divided into reciprocating Jaw crusher (orSingle toggle jaw crusher) and simple jaw crusher (or Stone crusher). And also PE Series Reciprocating jaw crusher, Mobile jaw crusher that are with reasonably made structure, reliable performance, and very firm and can be used consistently for long years.
In the jaw crusher, shown in Figure below, the moving jaw is pivoted at the bottom. The minimum movement is thus at the bottom and a more uniform product is obtained, although the crusher is less widely used because of its tendency to choke. The large opening at the top enables it to take very large feed and to effect a large size reduction. This crusher is usually made in smaller sizes than the Stag crusher, because of the high fluctuating stresses that are produced in the members of the machine.
Types of jaw crusherDouble jaw toggle crusher, the eccentric shaft for the counter-clockwise rotation, therefore, the block of material into a pushing and holding downs the role. Moving from the swing jaw throughout the process, the Ministry of items about the level of the lower swing spout 1.5 times, while the lower part of the vertical swing is slightly larger. The whole jaw, the vertical oscillation amplitude of the horizontal swing of 2-3 times. Level swings on big small, it is beneficial for the upper part of the material for crushing, the crushing chamber and make the material more evenly by the crushing force. Great swings vertically on the small, will help make a complex piece of jaw movement, therefore, not only on the material block squeeze play, splitting, bending effect, but also from the grind twist effect, it can break some of the slightly sticky materials.
