Concrete gravel production has a wide range of raw materials, simple process, low cost, high market demand and other characteristics, so more and more investors pay attention to it. This article will introduce in detail what kind of rock is suitable for the production of concrete gravel? What kind of gravel crusher machine does a concrete gravel production line need?
What kind of rock is suitable for the production of concrete crushed stone?
- High hardness. The hardness of concrete gravel on raw materials is higher, limestone, dolomite, and marble this soft material is not suitable for the production of concrete gravel, commonly used concrete gravel raw materials are granite, basalt, quartz stone and so on.
- The surface is coarse and dry. Rough surface of the raw stone is more beneficial to the bonding of concrete. For example, the black bluestone as a high hardness stone, the section of the stone is smooth, not easy to bond with cement, so it is not a better raw material of concrete gravel.
- Wash the stones. The better raw material of concrete gravel needs to be cleaned by the sand washing machine. It is necessary to ensure that the surface of the stone is clean and pollution-free, for example, soil and oil on the surface of the stone are not allowed. The high quality concrete gravel selection of raw materials is very important.
What kind of gravel equipment does a concrete gravel production line need?
It roughly includes coarse crushing equipment, medium and fine crushing equipment, sand washing equipment, feeding equipment, screening equipment, conveyor belt and other auxiliary facilities. Reasonable configuration between the equipment, effective operation, the production of high standard of concrete gravel is achieved.
But such a concrete gravel production line is not fixed, the specific way to choose and build depends on the actual needs of users. Common equipment of concrete gravel production line are:
● Concrete gravel coarse crushing equipment: jaw crusher
It is often used for rough stone crushing processing, with incomparable feed size of other crushing equipment, is very good at processing large diameter materials, crushing ratio is large, can quickly break the stone into small stone particle size, so as to enter the next crushing process.
● Concrete gravel fine crushing equipment: cone crusher
Due to the production of concrete gravel raw material hardness is high, in the selection of fine crushing equipment, it is recommended that you use cone crusher, a specially crusher machine for hard rock. High crushing efficiency, small wear, a variety of crushing chamber, the stone coarse, medium and fine crushing can be finished in one step.
● Concrete gravel cleaning equipment: sand washing machine
Cleaning of stone is also an essential step in the concrete gravel production line. The commonly used cleaning equipment is divided into wheel sand washing machine and spiral sand washing machine. The former is slightly lower in price, smaller in capacity and more energy saving; The latter has a slightly higher price, higher production capacity and higher cleanliness, but with a little waste water, the two sand washing equipment can realize the recycling of water resources.
In addition, concrete gravel production line can also choose mobile equipment, no infrastructure, free transfer, fast production nearby, more energy saving and environmental protection. The mobile crusher also has great flexibility, which can be freely matched with jaw crusher, cone crusher, impact crusher, hammer crusher and other types of equipment. It has multiple functions of feeding, crushing, screening and so on. It can be operated independently or produced jointly by multiple equipment, which is convenient, fast and high yield.
The above is a simple introduction of the rock and equipment configuration for the concrete gravel production line.
