Stone Crushing Machines
Stone Crushing Machines Introduction:
Stone crushing machines was invented in 1858 by the United States, Black appeared earlier broken equipment, suitable for compressive strength at 147 ~ 320MPa various ores and rocks of coarse, medium, fine crushing. Its structure is simple, rugged, reliable operation, convenient repair and maintenance, and the production and construction costs are relatively low, therefore, widely used in mining, metallurgy, stone industry, building materials, electricity, water conservancy, transportation and other industrial sectors.
Stone Crushing Machines Common Sense:
The stone crushing machines 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 machines 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 machines should be an optimum number of revolutions.
Stone crushing machines eccentric shafts, connecting rods, movable jaw plate, shaft and liner wear parts, lubrication and replacement needs constant attention.
Stone Crushing Machines Advantage:
1, The crushing chamber is deep and smooth, enhancing the feeding capacity and production.
2, High crushing ratio, homogeneous final product.
3, Adjusting the discharge opening through gasket , the adjusting range is wide to meet the customer's different requirement..
4, Safety and reliable Lubricate system, easy maintenance and replacement.
5, Single machine can save energy to 15%-30% , a set of machine can save energy doubly.
6, Low noise and little dust.
Operating Environment:
In the process of huge stones are broken into small stones, the first crusher is usually referred to as a "master" crusher. The longest history, but also the most solid crusher stone crushing machines. stone crushing machines feeding the material from the top of the entrance into the crushing chamber containing jaw teeth. Jaw teeth with great force the material to the top of the wall will be broken into smaller stones. Support the jaw movement is an eccentric shaft, this axis throughout the body architecture. The eccentric motion is usually generated by a flywheel fixed on the shaft ends. Flywheel and often eccentric support bearing spherical roller bearings, bearing extremely harsh working environment. The bearings must withstand tremendous impact load, abrasive sewage and high temperature. Although this work is extremely harsh environment, stone crushing machines still need to work very reliably.
