Jaw Crusher is mainly used to crush various medium particle size of ores or large materials. According to the feed inlet width, it can be divided into three types: large, medium and small. Large machines are those with a feeding width over 600mm; medium machines are those with a feeding width of 300-600mm; small machines are those with a feeding width smaller than 300mm. Jaw Crusher (abbreviated as J Crusher) is widely used in mine, metallurgy, building, material, highway, rail way, hydraulic engineering and chemical industry, etc. The maximum compressive resistance of the crushed materials is 320Mpa.
技術優勢和特點/ TECHNICAL ADVANTAGES AND CHARACTERISTICS
The crushing ratio is big with a uniform product granularity; the crushing cavity is deep with no dead zone, thus improving the feeding capacity and output;
The adjusting device of gasket-type outlet orifice is reliable and convenient, with a large adjusting range, which increases the flexibility of the machine;
The adjustment range of outlet orifice is large, which can meet the requirements of different users; energy-saving equipment: The energy saving of a single machine is 15%-30%, and the system's energy saving is more than double of that; low noise and little dust.
The lubrication system is safe and reliable, with convenient part replacement and little maintenance work; the structure is simple with a reliable performance low operating cost.
工作原理/ OPERATING PRINCIPLE
The working parts of the Jaw Crusher consist of two jaw plates. The fixed jaw plate (fixed jaw) is fixed on the front wall of the machine body vertically (or the top tip slightly outward). The other is rotating jaw plate (rotating jaw), which is inclined in its position. And the two jaw plates form a crushing cavity (working cavity) with large top and small bottom. The rotating jaw plate is reciprocating periodically against the fixed jaw plate, sometimes separately and sometimes closely. When they are separated, the materials enter the crushing cavity, and the finished products are unloaded from the lower part; when they are approaching, the material loaded between the two jaw plates is crushed by the effects of extrusion, bending and splitting.
