Silica Sand Processing Plant Equipment
Silica Sand Processing Plant Equipment Introduction:
Silica sand processing plant equipment, also known as PCI impact crusher combined in the development of mining machinery and equipment for many years on the basis of the actual situation of the domestic system of sand production, learn from American liming famous "stone at stone crusher principle and technology research and developmentgravel of efficient production equipment with domestic and international leading level. Sand performance plays an irreplaceable role in a variety of ore fine crushing equipment. It can be a variety of hard rocks (rocks, granite, basalt, limestone, river gravel, etc.) metal and nonmetal ore broken into compliance with various size of the construction sand and gravel material, sandy uniform particle size, high compressive strength, than natural sand, sand hammer breaking production more in line with the requirements of a high standard of construction sand, that can enhance the quality of construction.
Silica Sand Processing Plant Equipment Maintenance:
1, Regularly observed inside the crusher wear, the center of the feeding tube, cone hat, impeller, indecent Road liner circumferential shield, wear block wear, timely replacement or repair. The wear blocks should be replaced at the same time, wear blocks of the same weight. Observed non-crusher process open door to observe the inner workings of the case, in order to avoid danger.
2, Impact crusher each work 400 hours should be added to the amount of grease, 2,000 hours of work to open the spindle assembly bearing cleaning generally work 7200 hours, the replacement of a new bearing.
3, Transmission triangle belt tensioning force size should be adjusted appropriately, to ensure uniform Triangle tape by force. Dual motor drive, on both sides of the triangular tape should be grouped matching, we each group its length as consistent as possible. Should ensure that the difference between the two motor current does not exceed 15A.
Silica Sand Processing Plant Equipment Working Principle:
Silica sand processing plant equipment into the hopper, sub-feeders, eddy crushing chamber, impeller body, spindle assembly, the base transmission and motor consists of seven parts, stone rock principle, more materials for their own collision broken.
Material from the feed hopper into the silica sand processing plant equipment, the material is divided into two parts by the sub-feeder, and in part by the middle of the sub-feeder into the high-speed rotation of the impeller, the impeller being rapidly accelerated acceleration of up to several hundred times the acceleration of gravity , then the speed of 60-70 m / s from the impeller three runner uniform projectile out, first of all with broken by the impact of the part of the sub-feeder four weeks since the closing falling materials, and with the impact of the whirl cavity lining materials on the material lining rebound, oblique impact to the top of the whirl chamber, reflection, deflection downward movement of the collision with emitted from the impeller material again, such a material eddy the crushing cavity by twice as well as several chances to impact, friction and grinding crushing effect, finally lost the energy of the material discharged from the crushing cavity. Throughout the crushing process, the materials of mutual self-impact crusher, not in direct contact with the metal components, but with the material lining shock, friction and crushing, thus greatly reducing the wear and tear of equipment, extend the life of the machinery. The same time, the whirl chamber clever internal airflow self-circulation, but also to maximize the elimination of dust pollution.
Silica Sand Processing Plant Equipment Application:
Silica sand processing plant equipment is suitable for soft or medium hard and extremely hard materials crushing, plastic, widely used in a variety of ores, cement, refractories, aluminum where the soil clinker, emery, glass raw materials, mechanism building sand, stone and a variety ofmetallurgical slag, especially for silicon carbide, carborundum, sintered bauxite, US-sand contour hard, special hard and corrosion-resistant materials is higher than other types of crushers yield efficacy. Engineering mechanisms sand, cushion material, asphalt concrete and cement concrete aggregate ideal production equipment. In the mining industry, widely used in grinding the preceding process, it can produce large amounts of iron ore fines, reducing the high cost of grinding load.
