Mainly used for mining 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, a certain degree of overall improve mining process, hammer apparatus in the large mining processing as 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. Hammer apparatus in the development is the foundation of ascension continually application hammer apparatus, product performance also in the continuous improvement, to a greater extent to meet demand.
In the 1980s, hammer apparatus using two jaw wants the extrusion and bending role material of various hardness, raw material crushing or crushing processing; If work only for simple dynamic jaw, the industry says simple circular swing swinging jaw type hammer apparatus; If working when make arc wobble also make fluctuation movement, says complex swinging jaw type hammer apparatus. To in the early '70s, 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 ore or rock large packaging machine. Equipped with broken cone in the top of the bearing spindle central crossbar, within bushing is placed in the bottom hole. The eccentric 101 Collar turns, broken lines around the machine for cone eccentric spinning back sports its broken movement is continuously, so work efficiency higher than the jaws type hammer apparatus.
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 broken objects are more likely to result in accidents, and because of finely homework, discharging granularity, must be in strict lining board to adjust discharging after wearing mouth, thus cone adjustment device of insurance and hammer apparatus more necessary than crushing assignments. Tapered type hammer apparatus and spinning back hammer apparatus identical, but only applicable to the broken or finely homework in stave machinery. Cone crusher unceasing development, a spring cone crusher, cone crusher simmons single cylinder hydraulic cone crusher and hydraulic cone crusher and multi-cylinder such hammer apparatus equipment.
Meanwhile, of hammer type hammer apparatus and fight the unceasing development, especially in hammer apparatus back more crushing ratio of hammer apparatus, and can make better use of the rotor high-speed impact energy. But due to wear, it easily plate hammer in the application of hard material breakage also restricted on, usually to crushing, crushing or finely limestone, coal, calcium carbide, quartz, dolomite, vulcanization iron ore, gypsum and chemical raw materials and other hard brittle materials below.
Hammer apparatus is widely used in mining, metallurgical industry, building material, highway, railway, water conservancy and chemical industries multitudinous departments. Gravel currently used mechanical have hubei, impactor, impact crusher, concrete crusher, compound crusher etc for building materials, bricks, coal, metallurgy, mining, power, light industry and industry departments, used in crushing coal, shale, cinders, carbon, lime, cement ShuLiao, peng bentonite and hard to brittle material crushing, crushing and finely.
