What Equipment Should be Selected for Marble Processing?

Marble, a kind of metamorphic rock, has a high content of calcium carbonate, and it is also a widely existing rock mine in nature. It has the characteristics of high hardness, hard texture and strong plasticity, which mainly used inindustries such as building materials, chemical industry, and construction. So what kind of equipment should be used to process marble? Generally speaking, the following types of equipment are used for processing marble from lump to powder:
1. Coarse crushing equipment: jaw crusher
Jaw crusher is a commonly used rough crushing equipment, which is used in various production lines. The movable jaw plate is used for extrusion crushing with simple structure, large crushing ratio and no dead zone in deep cavity crushing. Therefore, the marble crushing will not cause blockage, the production efficiency is high and the size of the discharge opening can be adjusted flexibly to process marble products with different particle sizes.

2. Medium and fine crushing equipment: impact crusher
The discharge port can be adjusted, and usually the stone can be crushed to less than 50mm, which is very suitable for processing marble. The structure design is reasonable, the operation is stable, the quality of the equipment is stable, and it is not easy to break down. The discharging particle size can be controlled by adjusting the distance between the impact board and the hammer, and the crushed finished product has good and uniform particle shape. The combination of high strength and wear-resistant hammer head can save materials and reduce waste.

3. Sand making equipment
Sand making machine is also called impact crusher, vertical sand making machine, etc. The discharge particle size can reach the standard of fine sand, which is a more commonly used fine crushing equipment. If the user needs marble sand, the marble sand making machine is an indispensable equipment. It can be processed into fine finished aggregate of machine-made marble with three-dimensional grain shape and reasonable gradation, which has very high application value.

4. Milling equipment
The marble mill can process 80-2500 mesh marble powder, and the finished mesh can be controlled by powder selector and analyzer. Marble pulverizer has a very high level of automation, which can achieve unmanned operation, high efficiency, and environmental protection.

Marble processing process
The first stage: crushing and sand making
The coarse crushed marble materials are sent into the screening equipment for classification. The materials below 40mm can enter the sand making machine directly, and the materials above 40mm need to enter the medium crushing equipment again for crushing. Medium crushing equipment can choose to impact crusher or cone crusher.

The second stage: grinding
After coarse crushing and fine crushing, the massive marble materials are sent to the storage bin by bucket elevator. Then through the electromagnetic vibrating feeder, the material is evenly, quantitatively and continuously sent to the grinding cavity for grinding. The ground powder is blown to the separator for separation under the action of the blower, and the unqualified powder after separation falls back to continue grinding. The qualified fine powder is sent to the storage bin by the pipeline, and finally the finished powder is output through the discharge valve.

The above is the process of marble crushing, sand making and grinding production line. The marble processing plant produced by Nile Machinery not only has a wide variety and complete models, has good quality and performance, and more importantly, the price is very cheap. For those customers who have just joined the marble industry, who do not have sufficient funds but want to buy good equipment, the marble processing machine produced by Nile Machinery can completely solve the problems and bring considerable benefits to users.
