Also known as jaw crusher, which consists of two jaws of the stationary jaw and movable jaw, simulation animal in the two jaw movement digest food and ore crushing. Widely used in mining, building materials, roads, railways and other industries, together with the unique advantages of medium-grained broken in a variety of ores and bulk materials known.
In general, the judge jaw crusher equipment performance parameters the two processing capacity and the maximum allowable size of the feed. Of course, even the same specifications jaw crusher design, the maximum allowable size of the feed are not the same. Many companies in the international distance between the fixed tooth plate and activities tooth plate, and the resulting products marked with the same specifications, and domestic mainly with reference to the former Soviet Union standard feed opening width fixed tooth plate of sharp teeth (tooth bottom) activities tooth plate tooth bottom tooth tip distance for the calculation of standard products, domestic and foreign enterprises in fact often small teeth deep distance, large-sized crusher teeth deep for the 60-100mm, thus domestic product allows feed often small in size 50-80mm.

    Affect jaw crusher processing capabilities in addition to the feed inlet size, the degree of adjustment of the port of discharge also have a certain impact on the processing power of the jaw crusher equipment as well as the scope of application. And in this regard, do abroad often than domestic better feed inlet adjustment. Example, Nordberg C100 jaw crusher, closed side port of discharge setting (C, S, S) 125mm, processing capacity of 265t / h, the corresponding PE750X1060 products; processing The capacity of 195t / h, approximately 25% lower. Thus, in 250X300t / h scale gravel pits production line, the C100 type used as primary crushing equipment to meet the requirements and PE750X1060 type reluctance.
Of course, jaw crusher gap at home and abroad must not only reflected in the crusher and crusher price gap is also reflected in the management and development of the concept of the crusher manufacturers and other aspects of the gap, if domestic the lithotripsy machine manufacturers own crusher equipment crusher in the international competition in order to gain an advantage, to the international learning leading manufacturers of crusher crusher equipment is an inevitable trend.
