Hammer impact crusher is mainly made of electric motor crate, rotor, impact plate and actuating device, suitable for medium hard and light erosive materials. It integrates the advantages of hammer crusher and jaw crusher, which has the advanced design concepts, top-ranking design technology, such as higher ratio of reduction, more evenly crushing size and lower power consumption.The hammer impact crusher is applicable crushing brittle minerals, such as: limestone, basalt, granite, cobble, feldspar, fluoride, and concrete, with compression strength no more than 300Mpa and humidity no more than 15%, is widely used in the industry of mining, cement, building materials, water conservancy, metallurgy and chemicals. It can secondly and fine crush materials.Working principle: When materials enter the working area, they'll be struck by the hammers on the rotor and be thrown onto the impact plate. The materials which spring back from the impact plate will be struck by the hammers again until they reach the desired size, after which the materials will fall through the mesh under the rotor. The distance between the impact plate and the rotor can be adjusted to meet shape and size requirements.Performance and structure of hammer crusherThere are many types of hammer crushers, according to the structure characteristics they may be classified as follows:1. According to the number of the rotor, there are the single rotor hammer crusher and double rotor hammer crusher;2. According to the rotary direction, they are reversible (rotor into two directions) hammer crusher and not reversible hammer crusher;3. According to the row number of the hammer, they can be divided into single type hammer crusher (the hammer are installed in the same rotary level) and many platoon type hammer crusher (the hammer distributes in several rotary levels) ;4. According to the connection of the hammer with the rotor, they can be divided into fixed hammer crusher and flexible hammer crusher. Fixed hammer crusher is mainly used for finely grinding the soft materials. We'll introduce these content in the following sections.Hammer crusher is widely used in cement, chemical, metallurgic industry and so on for crushing medium-hard stuffs, such as limestone, slag, pet coke, coal, etc. The final product can be adjusted according to customers demand through equipping different gratings. Jaw Crusher is one of main equipment of stone crushing, is ideally suitable for crushing all kinds of ores and crushing the big size materials, the highest anti-pressure strength of crushed material is 320 Mpa,having two types: primary crushing and secondary crushing.jaw crusher has been sold to 75 countries, the price and quality of jaw crusher is widely recognized, we always stick to be your satisfying partner.
