This company makes the Mclanahan revolving coal breaker, which is loaded with the drill hole lamina crib Rosa, using in the stave apple coal hungry medium degree of hardness the coal, and the productivity is extremely big. This machine characteristic is the driving gear and the tube bodies have the extremely precise concentricity. Tube in vivo is loaded with the wear-resisting backing, and the tube body both sides give the material reason and the ex-dinning reason for the non resistance. This function simultaneously completes breaks and sieves two parts in a revolution work.
American Mcnally Pittsburg Corporation makes the stave lump coal specially the coal breaker —— “Geomantic” the double rolls breaker, the heavy double rolls breaker, the revolving breaker, two sections of four roller Geomantic breaker and the single roll breaker. The Geomantic breaker unique feature is: Using tensile strength very high gear which Mcnally Corporation develops, for dustproof has used the good packing assembly. When the breaker moves, can change the position of the action roller to adjust the product the granularity. This company makes two sections of four rollers breaker is made by two double rolls breaker assembly.
Luxembourg Mecan-Arbed Corporation makes the large-scale Abed pin roll breaker, used in thick garrulous or the garrulous work, stave brittleness or hard material (also moisture content big and coherent high material).This company makes the pin roll breaker together with 13 kinds of specifications. The smallest pin roll breaker, of which actuation power is 237 , and its productivity is 150~200 , the product granularity is 50 . The actuation power of the largest-scale pin roll breaker is 2600 , and productivity is 2400~3000 , and the product granularity is 300~400 .
The Mammoth breaker made by the West German QK Corporation is one kind of single rotor hammer type breaker, and is suitable in the single roll thick garrulous hardly to the hard limestone and cement raw material. This kind of breaker altogether has 12 kinds of specifications: For the material granularity is 0～25 , the actuation power is 100～3500 . The Titan breaker made by this company, can break the material is similar to the Mammoth breaker, but gives the material granularity is 1200～2300 , and productivity is 220～1200 , and the actuation power is 2170～2900 .
This company makes impact type breaker has 18 kinds of specifications. Giving the material granularity is most greatly 400～1600 , and productivity is 20～1800 , and the stave product granularity is 0～150 , and the actuation power is 22～2000 .
The HBK hammer type breaker made by this company mainly is used in the crushed stone which the stave road building project needs (hardly to hard).
QK Corporation makes the garrulous hammer type breaker have 10 kinds of specifications, using in stave as the hard material or thick garrulous cement raw material, and the electric motor power are 30～400 , and the stave productivity is 20～280 .
Czechoslovakian Pragoinvest Corporation making 8 kinds of specifications the OKD impact type hammer type breakers, is used in the stave productivity being high, the reduction ratio is also big. The OKD breaker structure characteristic is, having the giant stave cavity above the large-scale rotor. Through stave hammer revolving, project the material to the stave cavity wall on, and cause it to attack stave. The bulk material which has not been broken falls down the discharge hole place riddle, attacking stave once more.
This kind of breaker been used the hydraulic control system, is loaded with the riddle in the breaker behind dump mouth place and used in disassembling with installing the stave hammer the hydraulic unit.
West German PHB-Weserhutte(PWH) Corporation makes the single roll and the double rolls breaker, and its crushing roller may be the smooth roll, perhaps on the garrulous roller the chamfer, and is loaded with the stave tooth. This kind of breaker is used in stave hard or the soft material.
