Marble is a metamorphic rock, a medium-hard stone, mainly composed of calcite, limestone, serpentine and dolomite. Therefore, a lot of marble can be used as limestone for building gravel products. Although the hardness of marble is higher than that of limestone, it is not as hard as granite. Therefore, the configuration of many marble crushing production lines on the market is very similar to that of limestone production lines.

 

 

Marble crushing production line equipment configuration

Commonly used equipment include feeders, jaw crushers, impact crushers, sand making machines, vibrating screens and belt conveyors. The belt conveyor is configured according to the actual conditions of the production site. According to different process requirements, various types of equipment are combined to meet the different process requirements of customers.

Marble crushing production line process flow

First, the marble is preliminarily crushed by the jaw crusher. Then, the coarse material is transported by the belt conveyor to the impact crusher for further crushing. The finely crushed stone is sent to the vibrating screen to screen out two kinds of stones, which meet the needs of marble production. The sand machine feeds the granular marble into the sand making machine, and the other part of the returned material goes into the impact crusher for fine crushing. Part of the stones fed into the sand making machine is made into sand, which is cleaned by a sand washing machine (optional) and made into finished sand. The other part is fed into the sand making machine and crushed again.

On the one hand, this process solves the problem of serious wear of wearing parts. On the other hand, the two-stage crushing process and the high productivity advantage of the sand making machine also greatly reduce operating costs. This is also the most cost-effective marble crushing production line selection solution at present.

 

Advantages of marble crushing production line

1. Multi-stage laminated crushing equipment can minimize the wear cost of wear-resistant parts, while also reducing the reverse material after screening and increasing the production capacity of the production line.

2. Marble is a hard material, so we are very cautious in configuring wear-resistant parts. Such as jaw plate, tooth plate, rolling mortar wall, etc. If these wear-resistant parts are made of advanced wear-resistant materials and high-quality casting technology, their service life can be guaranteed.

3. The degree of production automation is high, and each shift has less than 3 production personnel, which reduces labor costs.

4. The machine-made sand produced complies with the national construction sand standards. The product has uniform particle size, good particle shape and reasonable gradation.

5. The equipment configuration is centralized and reasonable, covering a small area and easy to maintain.

 

Marble crushing production line selection and configuration requirements

1. Consider the hardness of the material and configure reasonable crushing equipment according to the hardness of the marble. The same model of crusher will have relatively low output when the hardness of the material is high.

2. Consider the size of the raw materials. On the one hand, the size of the raw materials will affect the output. On the other hand, it will affect the selection of the primary crusher. Avoid choosing a crusher that is too small and the aniseed material cannot enter, or choose a crusher that is too large, resulting in increased investment costs and reduced efficiency.

3. Consider the actual operating environment.
