Counterattack crusher is a new type of high efficiency crushing equipment, made up of many parts, back cavity of multilevel counterattack crusher, there is enough space, broken is suitable for large pieces of material of broken. Counterattack crusher plays an important role in every parts, rack is no exception, many manufacturers and users to frame or a great emphasis on the importance of, let’s frame to conduct a comprehensive analysis of the counterattack crusher, respectively from the structure, function, strength and welding technology and so on four aspects to elaborate.
1. The frame structure: the counterattack crusher frame by frame and the frame of two departments, with bolt connection each other. On the surface of the rotor axis line for the frame, it is equipped with a side door and back door for inspection, installation. For the next frame for rotor axis line, and by using the bolts should be fixed on the ground, mainly bear the quality of the whole machine. Rack inside all contact with the part of the ore are equipped with a replaceable wear resistant lining board.
2. The role of the frame: strong counterattack crusher parts interchangeability, vulnerability of small variety, is advantageous for the spare parts purchasing and management. Counterattack crusher frame to the triad structure, open the counterattack crusher at the back of the chassis, can be replaced plate hammer and counterattack plate, plate and so on maintenance operation.
3. The strength of the frame analysis: the strength of the rack for equipment is very important, because the counterattack crusher at work, its frame under the impact of the very large, so when the design should give enough compressive strength, four heavy industry to alert users to the strength of the frame to seriously, not only consider cost, installation, etc.
4. The frame welding analysis: counterattack crusher frame welding preparation with gas cutting or carbon arc air gouging processing groove, should guarantee the machining quality, preventing its surface uneven, not qualified to be grinding, groove surface must not have defects such as cracks, slag, stratification, otherwise the removal or repair.
