Project Report for Stone Crushing Plant S.A
Stone Crushing Plant Introduction:
This series of stone crushing plant is mainly used for a variety of materials, not more than 320 MPa compressive strength broken, crushing operations, with a crushing ratio, high yield, uniform particle size, simple structure, reliable operation, easy maintenance,operating costs and economic characteristics. The crusher has been widely used in mining, metallurgy, building materials, road, railway, water conservancy and other departments.
Stone Crushing Plant Performance Characteristics:
The performance characteristics: large crushing ratio, uniform particle size, simple structure, reliable operation, easy maintenance, low operating costs.
Stone Crushing Plant Working Principle:
The belt drives eccentric shaft rotating by motor. The vetical links will move up and down accordingly. The two pieces toggle plates are extended gradually when the vertical links goes up. The toggle plates will put movable jaw plate towards fixed jaw plate, the mineral stone in the crushing chamber( between movable jaw plate and fixed jaw plate) will be squashed, cleaved, and flexed and then be crushed. As the vertical links and movable jaw plate are backed by the power of spring and links, the discharge opening will increase, and the crushed mineral stone will be discharged. So we can say stone crushing plant discharges stone indrectly. The eccentric shaft goes a circle, there is half circle time will be used for crushing, the remaining time will be used for discharging.
Stone Crushing Plant Common Sense:
The stone crushing plant 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 stone crushing plant 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, stone crushing plant should be an optimum number of revolutions.
Stone crushing plant eccentric shafts, connecting rods, movable jaw plate, shaft and liner wear parts, lubrication and replacement needs constant attention.
