subject: Relationship Between Material Block And Specification [print this page] Relationship between material block and specification
The specifications of the jaw crusher is expressed by width B and length L. For example, 900 x1200 mm jaw crusher means the mine mouth width is 900 mm, length is1200 mm.
the width can be divided into large, medium and small three types according to jaw crusher discharge port. Greater than 600 mm to the width of the discharge port for large-scale, feed mouth width of 300 to 600 mm for medium-sized to the width of the discharge port is less than 300 mm for small. Given into the jaw crusher to mine production than to the width B of the discharge port 15 to 20 percent, that is, to the expected maximum degree D = 0.85 ~ 0.8B.
There are two common jaw crusher (jaw crusher):
On the acting and the next move of type. Dynamic type jaw crusher Pai mine mouth width unchanged, the work often blocked, affecting the normal work. So it has been eliminated.
The jaw crusher is composed of the following main components:
Fixed jaw plate and the anterior wall of the rack, movable jaw plate hanging in the shaft, eccentric shaft, the vertical rod, bracket, transmission flywheel, two jaw-board the liner, with a spring lever bracket seat, adjust the block.
The working principle of jaw crusher (jaw crusher):
Motor through the belt so that the eccentric shaft rotation, the vertical rod up and down movement, when the vertical rod upward, driven by two brackets gradually stretched flat bracket to force the movable jaw plate to the fixed jaw plate forward, crushing chamber(ie ore being squeezed by the fixed jaw plate and the moving amount of space), the cleavage, the folding flexor role and broken. The downward movement of the vertical rod, toggle plate and movable jaw plate by the force of the spring and rod to the back port of discharge increases, the broken ore is thus discharged. The eccentric shaft of a turn each only a half cycle is used for crushing, followed by half a cycle for a row of ore. With other continuous broken machinery compared to larger power consumption, mechanical efficiency is low.
