Vertical shaft impact crusher sand manufacturing process suit for limestone crushing, it has the advantages of low unit energy consumption, good grain shape and low wear.Shortages the stone of 5~2.5mm is repeatedly squeezed and broke, has a poor crushing effect, higher power consumption.The finished sand has a large range of particle diameter and more in fine diameter, and the intermediate particle diameter (2.5 to 1.25 mm, 1.25 to 0.63 mm particle diameter) has a small content.The control of the particle size modulus of the finished sand is difficult (controlled by human).
As an impact crushing machine adopts an impact crushing method, the aggregate has been crushed by 2-3 crushing cavities, and multiple surfaces have been crushed by hitting impact plate.Whats more, the material is struck along the texture of the stone, so the product shape is almost all cubes.Even if crushing produces andesite with many needles, the needle content of the finished product is less than 12%.Flaky stones are not good for the strength of concrete, and it is not easy to form a solid skeleton.Cubes and spheres of stones have little effect on the fluidity of concrete and can ensure the strength of concrete.Therefore, at this point, the impact crusher meets the requirements of the ideal aggregate.The traditional crusher produces a large amount of finished products in the shape of needleswith unevengranularity, morepowder, andlow yield.in addition, because the particle size is not uniform or does not meet the specifications of the finished product, there will bereturning charges andwaste.the formerneedsto be processed twice or more, and the waste will be directly discarded.
Impact crushers (recycle) rcp capacity chart product gradation (output gradation based on virgin aggregate with controlled feed size).
This keestrack r3 impact crusher is the top compact crusher in the industry.It provides optimal results and product shape with one of the lowest equipment costs.Combined with its easy transport dimensions, superior fuel efficiency and high capacity, its ideal for primary and secondary crushing, construction and demolition, and concrete or landfill recycling.
Impact crushers create material reduction by providing a sudden impact force that causes the material to shatter along all the weakest fissures in the stone.Controlling the flow of the material through the impact crusher requires features that vary from one style of impactor to another, and this is what separates mclanahan from the other manufacturers.Essentially, the material enters the crushing chamber along a controlled feed angle.A spinning rotor assembly strikes the stone with a predetermined force sufficient to cause fragmentation.The trajectory of the material is then controlled to divert the flow back into the rotor circle, where the hammers (blowbars) continue to impact the material.Adjustable curtains or similar means are used to adjust the retention of the material flow for optimum output material characteristics.The impacted material flow then exits the crusher through the base frame.
Mclanahan offers a wide selection of impact crushers for quarried limestone and semi-abrasive minerals.Mclanahan draws from the 75 years of field experience with the universal line of impactors, which includes impact breakers and andreas-style impactors.At present, we offer the new holland-style primary impact breaker and the maxcap x-series primary, providing a means to reduce quarry shot and rom materials at rates exceeding 2,000 tph.We also offer versacap p-series impactors for heightened portability as a primary crusher.The versacap r-series is also designed to accept large top size in highly friable materials, and will allow for single crusher reduction to 1-1/2 minus product.In the case of limestone and similar materials, we offer the ngs impact crusher as a secondary impactor, which is capable of producing construction grade aggregates or minerals of like size.These five lines of horizontal shaft impactors are available in multiple sizes to provide us the ability to offer the most appropriate crusher for your specific application.
Jaw crusher is often used as the coarse crushing equipment of aggregate production line, followed by impact crusher or cone crusher, and then added sand making machine (shaping machine) for shaping.
Summarythis company is devoted to machine-made sand development and export to abroad sand the manager of this company succesful purchases two suits of vsi5x9532 centrifugal impact crusher and a suit of vsi1140 centrifugal impact crusher from our company.
(1) this combination process possesses the advantages of vertical shaft breaker and rod grinder, and overcomes their respective shortcomings, such as the problem of medium diameter content, excessive loss of stone powder, which improves the sanding rate.(2) vertical shaft impact crusher + rod mill, which can flexibly adjust the fineness and stone powder content of the finished product according to the change of raw materials, ensure the quality of finished sand, and effectively control the cost of sand making.(3) more complicated and need higher equipment costs.
3.Strong adaptability to materials.Various of rocks can be well shaped through the impact crusher.It can also provide a fine material for the grinding equipment.Therefore, the impact crusher is popular with the mining industry.
