How to solve problems in stone crusher plant

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 sandstone aggregate production line mainly depends on reasonable equipment selection, which is generally determined by material hardness, soil content and corrosivity index. Some of the production line investors did not find the formal design units, or just copied the equipment selection of other enterprises, which did not conform to their own production reality, which would cause problems such as irrational selection.Taking basalt, granite, diabase, and other materials with high corrosive index and hardness as examples, in order to pursue better product size, the production line mostly uses hammer or impact crushers, but such crushers have large losses. Frequent replacement of wearing parts such as hammer heads or impact plates makes the correspondingly higher production costs, which is not conducive to market competition.It is difficult to completely solve this problem even if the process is adjusted. Only by replacing extrusion type such as cone crusher, can we ensure the stable operation and continuous development of the production line.

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.

3.Environmental issues

The environmental protection quality of formal design production lines must meet international requirements, but there are still some production lines located near the finished product in bulk and in the vicinity of the second-break impact crusher with large dust.To solve this problem, you can calculate according to the position and number of dust collection points first, and place a dust collectors with sufficient air volume in front of and behind the crusher discharge point to reduce dust.If the dust is near the bulk of the finished product garage, in addition to the dust collector, a centrifugal fan can be placed between the top of the warehouse and the bulk machine, and water spray is placed at the material outlet of the bulk machine to reduce dust.When the materials are piled up, externally discharged fugitive dust is generated. The height and capacity of the piled materials can be calculated to add a water spray dust removal device.
