subject: Impact Crusher And Stone Crusher Make Construction Easy [print this page] The machine uses high-speed rotation of the rotor on the material impact of the hammer under the action of plate material was not only broken, but also for a larger speed and kinetic energy in the crushing chamber to the rack on the impact of the impact plate, or block of material shocks occur between each other to achieve the material crushed. Back in 1965, designed by the Institute of Anshan and do experiment of impact crusher. And compare with the cage mill and hammer mill for productivity, energy consumption, repair and maintenance, etc. Through the test, impact crushers are superior to cage mill and hammer crusher, simple in structure, power consumption, crushing ratio, uniform particle size. Therefore, it has been widely used in metallurgy, coking, chemical, building materials, refractories and other industrial sectors.
Impact Crusher crushing ratio is 40 or so, up to 150. Coarse Crushing with the crusher feed size can be up to 2m3, particle size less than 25mm, directly into the mill; Fine crushing with the crusher product size less than 3mm. Selection of a suitable crusher can be replaced in the past two or three of the broken, to reduce the number of broken segments, to simplify the production process, but also can improve mill output.
About 80 years ago, mainly from the development of concrete river gravel aggregate deposits, particularly in hydraulic concrete aggregate, in line with the principle of local materials, is the most important river gravel aggregate resources; some big cities such as Beijing , Nanjing and other aggregate supply are basically similar. But with the water conservancy and hydropower project was gradually transferred to the upper reaches of the river, river gravel deposits in small and scattered, less work required to take after the excavation of the rock crushing machinery manufacturing artificial stone aggregate particles become necessary. The aggregate supply of large cities, but also because of river deposits excavation and exhausted, to a centralized production of artificial aggregate crushing, so that an increasing proportion of artificial aggregate. For example, Hankou District, Wuhan City in the dwarf town and the quarry in the Wuchang district is located. With the development of economic construction, China's aggregate will become a huge industry, estimated annual demand for concrete aggregate about 40 billion Tons; others such as road engineering, railway engineering, airport pavement projects with an estimated annual demand volume of 60 billion Tons. In other words, the aggregate annual demand is about 100Tons.
Modern rock machine functions, hard rock machine complete with a variety of aggregate grain size needed for the production, you need the first stage, second stage ... ... followed bycrushing, step by step, to reduce the mineral aggregate particle size.
