In recent years,gravel aggregate has become a very important and essential raw material in construction projects such as bridges, water conservancy, and roads.However, due to factors such as the market, raw materials, and the level of the design unit, many sand and gravel production lines have encountered some problems in the process of production and operation and cannot achieve the expected results.
1. Selection of basic equipment
The success of the sand and gravel aggregate line mainly depends on the reasonable selection of some equipment, which is generally determined by the shelf, soil content and stop index. Production line investors have not found a formal production design unit, or just copy the equipment selection of other companies, which does not conform to their own production reality, which will cause problems such as unreasonable selection. Based on the most important stocks of basalt, granite, diabase, and other support indexes and structures, in order to pursue better product granularity, the production line mostly uses hammer crushers or impact crushers. quantity. Frequent replacement of hammer heads, impact plates and other wearing parts will result in corresponding production costs, which is not conducive to market competition. Even if the process is adjusted, it is difficult to completely solve this problem. The stable operation and sustainable development of the production line can only be guaranteed by replacing a crusher and other extrusion methods.
2. Material chute abrasion
Sand and stone aggregate products have the characteristics of multi-angles, some materials have certain abrasiveness, and the large drop in the process of material transportation, etc., makes the material chute service life shortened, and the degree of wear and impact is serious.So,for the chute with low impact force, the material steel plate shoud be as thicker as possible. This design needs to be avoided for materials that are easily clogged.
