Iron Ore Crushing Machine
Iron Ore Crushing Machine Introduction:
Iron ore crushing machine is mainly used to crush kinds of mining stones primarily, and the largest compression resistance of the material to be crushed is 320MPa. The iron ore crushing machine is widely used in mining, metall-urgical industry, building material, highway, railway, and stone industry.
Iron Ore Crushing Machine Application:
Iron ore crushing machine for cement, coal preparation, power generation and building materials, to adapt to the crushing of medium hardness and brittle materials, such as limestone, coal. The maximum compressive strength of not more than 1500kg/cm2.
Iron Ore Crushing Machine Common Sense:
The iron ore crushing machine is often due to improper use caused the crash phenomenon crusher to be crushed when the material, we must pay attention to pay attention to the uniformity of the material under, there is the hardness of the material was suitable, if perfect, canplus one step.
The main factors that generally affect the iron ore crushing machine nip angle and the number of revolutions. Nip angle is moving Hubei and the angle between the fixed jaw. According to the calculation of the maximum nip angle up to 32 degrees. The actual use are less than 25 degrees, typically about 18-20 degrees. Nip angle is too large, make up the ore crushing cavity extrusion, resulting in injuries or damage to other equipment, at the same time as the nip angle increases (broken than increase) decrease in productivity. Adjust the size of the port of discharge, and also change the size of the nip angle. In real life, according to the row of ore particle size to adjust the size of the discharge mouth. Therefore, to ensure that the product size requirements, try to Pai mine mouth amplification is reasonable. Pai mine mouth size can be adjusted by adjusting the block to adjust the size of the port of discharge, pay attention to the broken relationship between the ratio and productivity.
Within a certain range, an increase of the number of revolutions of the eccentric shaft, the production capacity of the crusher can be improved, but also increases the power consumption of the crusher unit weight of ore. The speed is too large, the time to discharge causes the crushing chamber has been crushed ore to produce clogging, but the production capacity to reduce, increase in power consumption, therefore, iron ore crushing machine should be an optimum number of revolutions.
Iron ore crushing machine eccentric shafts, connecting rods, movable jaw plate, shaft and liner wear parts, lubrication and replacement needs constant attention.
Performance Characteristics:
1, Crushing chamber depth and no dead zone, increased capacity and output feed.
2, Its crushing ratio, uniform particle size.
3, Gasket discharge opening adjustment device, reliable and convenient adjustment range, and increase the flexibility of the device.
4, The lubrication system is safe and reliable, easy to replace parts, maintenance workload is small.
5, Simple structure, reliable operation, low operating costs.
6, Energy-saving equipment: stand-alone energy-saving 15% to 30%, saving more than doubled.
7, The nesting population adjustment range, to meet the requirements of different users.
8, Low noise, less dust.
Iron Ore Crushing Machine Working Principle:
The main structure of the iron ore crushing machine frame, eccentric shaft, big pulley, flywheel, side guard plate, toggle plate, toggle plate back seat, adjust gap screw, reset spring, fixed jaw plate and movable jaw plate.
Work when the motor drive belt and pulley, through the eccentric shaft to make the movable jaw up and down movement, when the movable jaw rises larger angle between toggle plate and moving jaw, thus promoting the movable jaw plate close to the fixed jaw plate at the same time the material pushed pressure, rubbing, grinding, such as multiple broken; when the movable jaw down, the angle between toggle plate and moving jaw smaller, movable jaw plate lever spring to leave the fixed jaw plate material has been crushed in the gravity next, after the spout of the lower portion of the jaw cavity free unloading. The iron ore crushing machine is thus intermittent, crushing and unloading process in the jaw cavity alternately. With the motor continuously rotating crusher mobile jaw crushing and nesting periodicity, and mass production.
