Crusher machine known as back-breaking [1], mainly used in metallurgy, chemicals, building materials, utilities and other materials often need to move processing operations Crusher 1214 type, especially for highways, railways, water and electricity projects flow of stone work, depending on the type of large-scale processing of raw materials crusher, size and finished material requirements using a variety of configurations. China's current mobile crushing station and more used in the construction of urban demolition waste engineering, construction waste recycled aggregate crushing and screening become several different sizes and rules is to achieve recycling construction waste recycling project of the foundation. Advantages editing (1) back plate and the board hammer gap can be easily adjusted, effective control of a material particle size, particle shape is good; (2) the ore along the joint plane broken, so less power consumption, high efficiency; (3) no linkage, repair convenient, economical and reliable; (4) broken-function, high productivity, little mechanical wear, high overall efficiency; (5) high chrome plate hammer, impact resistance, abrasion resistance, impact force; (6) simple structure, small size , light weight, large capacity, low production costs. Feed opening, high crushing chamber to meet the high material hardness; (7) crushing ratio, up to 40 crusher manufacturers, crushing process can be simplified, can break into two or three sections of a broken, reduce Concentrator equipment costs
