Mainly used for mine hammer apparatus of mining technology, processes the stone crusher medium ore for gravel or broken stone mountain, generally refers to the raw ore after blasting, processed into demand of finished product size. Along with the development of mining hammer apparatus, certain degree understand the overall process to improve mining in large mining processing, hammer apparatus listed in the core equipment. According to the ore incoming gravel size and the grain-size size, hammer apparatus used for ore crushing, crushing and finely fields. Gravel is the development of the application of increased in hammer apparatus, finished product based on performance also in the continuous improvement, to a greater extent meet the requirements.
In the 1980s, hammer apparatus of material using two hubei wants to squeeze and bending effect, the various hardness material crushing and crushing processing; If work only for simple dynamic hubei, the industry called simple circular swing swinging jaw crusher; If work do the also be swinging circular arc, says that complex movement up and down the hubei type hammer apparatus. The hubei type hammer apparatus, widely used in mining, metallurgy, building material, highway, railway, water conservancy and chemical industries multitudinous departments, the hubei type hammer apparatus crushing compressive strength not more than 320 mpa various materials. Due to the requirements development, in order to avoid replacement parts and broken loss affect production, also can adopt hydraulic device to achieve meat machine insurance and adjust. Some the hubei type hammer apparatus adopts hydraulic transmission directly to drive to accomplish the dynamic hubei board, crushing action material. These two types of adopts hydraulic transmission device jaw type hammer apparatus, often referred to as hydraulic the hubei type hammer apparatus.
In the early 1970s, spinning back type hammer apparatus, use hammer in casing cone cavity of spinning back sports, to material produce extrusion, fracturing and bending role, crushing various hardness of large rocks and ores stave machinery. Equipped with broken cone in the top of the beam axis in support of bushing, the bottom is placed within the eccentricity of the collar hole. Bearing turns, broken lines around the cone do eccentric choose good exercise its crusher when the movement of continuous, so work efficiency than jaw crusher. The row in homework and the smaller the uniformity of partical usually better than crushing operational requirements of the high, therefore, in the bottom of the crushing cavity must be set for a parallel, and at the same time, still must area of crushing cone accelerated speed, spinning back to material by more than once in parallel zone of extrusion. The discharging port conical hammer apparatus, interfuse feeding less of a more jaw concrete crusher likely to cause an accident broken things, and because of finely homework, discharging particle size.
