Gravel Crushing Equipment,stone crushing,mineral processing
Rock crusher: is mainly used for processing crushed rock crushing equipment. Common rock crusher including: jaw crusher, impact crusher, cone crusher and so on. Rock crusher is widely used in water and electricity, highway, artificial aggregate, crushing and other industries.
Gravel Crushing Equipment
Work when the motor -driven belt and pulley , through the eccentric shaft to move up and down movement of the jaw , jaw rises when moving between toggle plate and moving jaw angle becomes larger, thus promoting the movable jaw plate close to the fixed jaw plate ,
while the material is squeezed pressure , rubbing , grinding , such as multiple broken ; when moving jaw down, between toggle plate and moving jaw angle smaller, movable jaw plate leaves the fixed jaw plate under the action rod, spring , has been crushed material in gravity Next , after the lower part of the jaw cavity free unloading spout . Thus the work of jaw crusher is intermittent, crushing and unloading process in the jaw cavity alternately. With the mobile jaw crusher motor for continuous rotation of the crushing and nesting periodicity , to achieve mass production .
When working , the motor drive pulley or coupling rotation, so by the horizontal axis , eccentric, moving cone hanging along the vertical axis to force the inner surface of the cone for Swing movement. In moving closer to the fixed cone cone section , moving cone material by extrusion , impact and bending and crushing , crushing cavity formation ; deviation in dynamic cone fixed cone where the material has been crushed under its own weight from the conical bottom unloading. Crusher for crushing stone to achieve sustained through continuous work .
Work , driven by the electric motor , the high-speed rotation of the rotor , while the material into the plate hammer area , and the impact on the rotor plate hammer crusher , then was thrown back again broken device was back plate and then bounced back with ore other ores or behind the rotor plate hammer throw collide , so the first crushing chamber by repeated shocks ore was crushed . Some of the ore in the first crushing chamber crushing to a certain size ,
the back plate and through the gap between the rotor and crushing chamber to the second row , continue to be hit repeatedly , until the desired particle size after the discharge port of discharge from the bottom of the crusher .
At work, believed to have heavy hammer crusher is directly 600-1800 mm maximum particle size of the material crushed to a period of 25 or 25 mm below the crusher crusher . Hammer crusher for cement , chemical, electric power, metallurgy and other industrial sectors crushing medium hardness materials , such as limestone , slag , coke , coal and other materials in the debris , crushing operations .
Rock crusher can process a variety of particle size is not more than 120-500 mm and not more than 320 MPa compressive strength of coarse, medium and fine material ores, rocks (granite, limestone, concrete, etc.)
