In addition to their traditional roles in mining and construction, environmental concerns that have spurred the search for more sustainable materials and technologies have found a new role for these machines in the recycling industry.The demolition that is necessary to pave the way for new developments results in huge quantities of used building materials, among them concrete.Sufficiently ground up, the old material becomes suitable for re-purposing.What then could possibly be a better means to tackle this requirement than with one of the bell range of impact crushers?.
Cylinder stone wash machine is used in the application of less than 80 mm) of the aggregate mud off work.Has the feeding large particle size, rinse aggregate can be lower than 0.5% hydraulic,mineral impact crusher water content below 2% advantages.
The impact crusher , using the theory of mass and velocity, works to break the feed material along its natural fracture lines with a secondary breakage perpendicular to the first.The initial breakage occurs as the falling feed material is "impacted" (whacked) by the rotating bars of the rotor.The secondary breakage, the one most people associate with, follows as the material is then accelerated into the breaker plates or bars.Proper speed of the rotor together with entry level speed of the feed material must work together to provide initial breakage without unwanted and unnecessary rotor wear.Due to the severe action of the impact crusher in nigeria , reduction ratios of 10:1 to 20:1 can be achieved.
Impact crusher, which is ideal for the primary and secondary crushing, is widely used in mining, quarry, metallurgy, building, highway, railway, construction waste plant, water conservancy and chemical industry, etc.It features high reduction ratio, easy operation, simple construction, repeatable performance, easy maintenance, and low consumption.
Impact crusher can crush each kind of coarse, medium, fine cubic material (granite, limestone and concrete etc) with feeding size not more than 500mm and crushing strength not more than 350mpa.Thus impact crusher is widely applied to secondary and tertiary crushing of various ores and medium-hard materials in railway, highway, energy, cement, chemical industry construction etc.There are many factors affecting the production capacity of the impact crusher, generally speaking, there are five factors, in the following we will described these five factors and propose appropriate solutions.
In order to achieve the goal of high efficiency, more and more mines are beginning to use mechanized operations to increase the mining rate and eliminate potential safety hazards, such as jaw crushers, impact crushers and cone crushers which are efficient and environmentally friendly crushing equipment.This not only ensures the personal safety of the mining workers, but also achieves efficient operation of the mine production.Therefore, in order to ensure efficient and safe mining activities to gain the support of the public, it is imperative to encourage the philippines mining companies to achieve mechanization.
These machines are invaluable in the mining industry where crushing is the first step in the processing of ore.Both impact crushers and alternative devices may be used sequentially in a number of steps until the resulting particles are of the required final diameter.Impaction may be applied by either a vertical or horizontal shaft with the latter limited to softer and less-abrasive materials such as limestone.
The accessories are the important part of impact crusher, which needs regular replacement.The accessories are also known as wearing parts if vertical shaft impact crusher, which mainly include plate hammer, side protecting plate, back plate, square steel and pressing block, which is made of high chromium and high manganese wear resistant materials.1.Plate hammer: plate hammer adopts high chromium alloy materials and the latest manufacturing technology, which has unique structure and design.The finished product is in cubic shape with no tension and fracture.It is the high wear resistance casting component.When the plate hammer wears to a certain degree, it should be timely adjusted or changed, so as to avoid the injury of fasteners and other parts.2.Side protecting plate: side protecting plate is an important vulnerable component of impact crusher.It will be worn after long term using, and its resisting ability will decline, thus often causing the accident and the decline of its sealing performance.Therefore, much dust will be generated.3.Impact plate: impact plate is generally welded with the steel plate.The back surface is provided with a wear-resistant lining board, which also can use the counter roller or grate board with a slot of the back surface.The fine content of the product is less, at the same time; the production capacity can be increased.It is energy saving, but it also has other defects, for example, the structure is complex, the back surface is hard to replace after being worn, fast abrasion, etc.4.Square steel: square steel is in square shape, which can be divided into welded and seamless types.Seamed steel is welded by steel plates to make square steel tube.Seamless steel pipe is formed by seamless steel, and its compressive capacity is far greater than the seamed steel.5.The pressing block: it is widely used in all kinds of mining machinery, which has high quality and stable performance.It can be produced according to the different production requirements of customers.After the load running test, the necessary adjustments must be made on the pressing blocks.Fote pressing block has excellent characteristics of stable chemical composition, reasonable heat treatment process, good wear resistance, high strength, etc.
Common limestone crushing line equipment includes fixed jaw crushers, impact crushers, belt conveyors and vibrating screens.This is in terms of overall device configuration.However, differenttypes of rock crushers will be configured according to customersactual needs.Thefixed jaw crusheris generally selected as primary crushing.If the second-stage crushing needs to be configured according tocustomersactual demands.
Sand production line usually consists of vibrating feeder, jaw crusher, sand making machine (vertical shaft impact crusher), vibrating screen, sand washing machine, belt conveyor, centralized electric control box and other equipment.The designed capacity is generally 50-500 t/h.After years of development and research, our company has designed a complete sand production line, which is popular with users.
