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.

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.

It is reported, the 2011 quarter, heihe river port to Russian exports of shovel soil of transportation, gravel, the sand gravel mechanical 517 sets of stone, value of goods 2143.37 million us dollars, 237.91%, 149.03% year-on-year rise respectively. Stone gravel printing machine has become the heihe port exports goods mechanical equipment led. From the outlet types see, jaw type hammer apparatus and the share of the largest, more than half of gravel conveying rate, followed by cone and counterattack type hammer apparatus, products with the dawn and famous brand hammer apparatus dhi technology to give priority to.
The heihe port to Russian export stone materials are mainly gravel mechanical sharply three reasons. A gravel rotary packaging machine and buildings is Russia, Russian market demand of mechanical construction the burgeoning period, along with international oil prices continue to rise, Russia, rapid economic recovery on the oil and gas, mineral development demand greater gravel machinery industry has developed rapidly, and while Russia native gravel mechanical product cant satisfy the domestic market demand, this gives China gravel machinery enterprises exports Russia created a huge opportunity.
2 it is China's gravel mechanical product cost-effective. In recent years, the rapid rise of China's gravel screen printing machine manufacturing, products cheap, deeply Russia customers.
Three is the unique geographical advantage heihe port. The heihe port and corresponding Russia blah GeWeiShen scottie city port closer, specification high, in product export transportation, customs declaration and logistics sales in Russia as the relative to other port superiority. Especially in export transportation aspects, freeze-up carrying export without transport equipment, but since drove way through customs exports.
From another Angle, since 2000, Russia to become one of the world's fastest growing architecture field, the construction market 10% ~ 15% growth per year. 2011, rapid economic recovery since the Russian market demand also gravel machinery, increasing. Rising property prices in Russia, investment under the influence of pouring into stimulating the vigorous development of the construction industry, which give Russia gravel meat machine and construction machinery market growth enormous business opportunities.
Meanwhile, Russia building and gravel machine depreciation rate has reached a 45% ~ 75%, local enterprises difficult to financing in technology and management backward, to meet the market demand of equipment. At present, the country is in the use of mechanical equipment, which accounts for 50% from import to 30% of the total imports. With China's gravel mechanical product matures, the numerous well-known brands also with high sexual price won the Russian customer extensive approbate, dhi technology is already and dawn Russian related industries have a few years close cooperation.
