The reason of cracking refeed phenomenon and SolutionsSeptember 20, 2016 • By bjyuan1026
With the development of economy, the construction of infrastructure, the country’s heavy industry production steadily, the demand of the development of mining, smelting, building materials, highway, railway, water conservancy, XZM Ultrafine Mill industry and the rapid growth of. In the trend of development, various crushing equipment market demand is bigger and bigger, the crushing equipment demand is suitable for crushing all kinds of hard, abrasion resistance of stone is also more and more big. Jaw crusher is introduced to the market in this environment, the highest compressive strength of 320Mpa jaw crusher is composed of a movable jaw and quiet jaw two jaw plate, simulation animal two jaw movement and complete crushing material crushing equipment.At present, the market price of the upper jaw crusher are falling, hand equipment put into production over a long period of time, the market competition is intense, on the other hand, is also due to cracking itself also has certain shortcomings of the system, in the use of the process there will be refeed phenomenon. This phenomenon is in fact the material being extruded feed port phenomenon, no material is crushed both the fixed and movable jaw extrusion, but by the two jaw plate extrusion, fly out from the feed port phenomenon. This includes a variety of reasons, from the analysis of equipment: first, parts and drawing size does not match, the machining and assembly of parts of equipment in the jaw plate, if the length, thickness, elbow plate length, frame cavity size, inconsistent with the design drawings size, it is easy to produce the material return.
