We all know that the application fields of crushers are very wide, in addition to metallurgy, mining industry, they also play a vital role in the construction industry.
For example, recently, we have a lot of concrete batching plant customers have begun to consult want to lay out their own sand and gravel production line, in the self-sufficient at the same time can also sell a portion of the sand and gravel to increase profits, not only to save their own production costs, but also to open up new markets, but also increase the profit of the batching plant, which can be said to be a one-two punch.
Aggregate stones used in commercial concrete batching plant are made of limestone, granite, basalt and other stones. The quality of these raw materials is relatively high, and the quality of the finished products produced is also good. In recent years, with the market price of sand and gravel aggregate constantly high, investing in a sand and gravel production line is a very wise choice.
So let’s look specifically at the specific process of investing in a sand and gravel production line. First of all, choosing the right crusher is the first step.
About the commercial batching plant stone processing production line, which crusher is appropriate to use?
How to choose a right crusher specializing in producing gravel for concrete batching plants
1. According to the type of stone
Medium hardness stone:
The source of sand and gravel aggregate in the commercial batching plant is mostly limestone, granite, basalt, cobblestone and other stones, generally for limestone and other medium hardness stone crushing operations, you can choose impact crusher, hammer crusher, fine crusher, composite crusher, etc., the output of good particle size, stone quality, particle size is more uniform, less acicular flake content, and so on;
Hard stone:
If for granite, basalt, cobblestone and other hard stone crushing operations, you can choose cone crusher, impact crusher, roller crusher, etc., these equipment wear parts are made of high quality wear-resistant and durable materials, long service life, high operating efficiency, low production costs.
2. According to the specifications of the finished product of the batching plant
- To produce crushed stone, choose cone crusher;
- To produce sand, choose impact crusher;
- To crush sand, impact crusher, hammer crusher, compound crusher, fine crusher, roller crusher can be.
The commercial concrete batching plant is generally required for the stone grade matching, the first level of matching is the use of a stone, the second level of matching is the use of two kinds of stone, the third level of matching is the use of three kinds of stone.
Grade matching needs to pay attention to the particle size:
- First-class formula: stone type 1.0cm-2.0cm
- Secondary formula: stone type 1.0cm-2.0cm grain size stone and 2.0cm-4.0cm grain size stone each accounted for 50%;
- Tertiary formula: stone type 1.0cm-2.0cm particle size stone and 2.0cm-4.0cm particle size stone each accounted for 30%, and the remaining 40% use 4.0cm – size 8.0cm stone.
3. According to the production scale of the batching plant to choose
- Large batching plant generally need a large amount of sand and gravel, so you need to use a large crusher processing, this time you can choose from the cone crusher, impact crusher, hammer crusher;
- Small and medium-sized batching plant with an hourly output of 300 tons or less, which requires a small amount of sand and gravel, can be selected from the fine crusher, composite crusher, roller crusher.
In summary, whether it is a concrete batching plant, or other specialized gravel processing plant, in the choice of stone crusher, should be considered from a number of aspects, the nature of raw materials, in and out of the size of the material, the size of the production capacity, the environment site, etc., are constraints on the selection of gravel production line equipment. If you have the need to build a plant, but there is no way to start to begin, may wish to contact us first from the beginning of the inspection equipment, to ensure that you design in place, service to the home!
