What are the sand making equipment?
1、The market background of sand making equipment
What are the sand making machine equipment? Sand and gravel aggregates are the most demanded materials in sand making. my country is now vigorously promoting urbanization and infrastructure production, and a lot of sand and gravel aggregates are urgently needed.
2、Sand making equipment mainly includes the following equipment
The most important part of a set of sand making production line is the sand making machine. The main effect of the sand making machine is literally sand making. . The semi-finished machine-made sand produced by the sand making machine fundamentally determines the quality of the finished machine-made sand. The particle size, particle shape, gradation, and fineness modulus of machine-made sand are basically affected by the sand making machine. Moreover, the materials of the machine-made sand are different, and the accessories of the sand making machine that need to be used are also different. For example, materials of different hardness need to use different crushing chambers, and different particle sizes need to use different rotors. Only by selecting suitable accessories can achieve the best sand making effect.
The semi-finished manufactured sand crushed by the sand making machine will be mixed with some large particle size materials. This particle size specification does not meet the requirements of the manufactured sand, and some projects have strict requirements on the size of the manufactured sand particle size. , so I used the equipment to be introduced next, the screening equipment.
There are many kinds of screening equipment on the market now: rod screen, cylindrical screen, circular vibrating screen, linear vibrating screen, high-frequency screen, probability screen, air screen, etc. The screening effect is the best, and the most widely used is the air screen. The air screen is not a simple screening equipment, but a screening system composed of five parts: vibrating feeder, horizontal distributor, air screening chamber, vibrating screen and blower. The use of the air screen system can improve the screening capacity and efficiency, and at the same time, combined with the negative pressure dust removal system, the remaining stone powder in the product sand can be eliminated, and the particle size adjustment technology can be used to realize the automatic adjustment of the product sand fineness modulus.
The particle size of the screened manufactured sand can now meet the relevant national standards, but some materials will generate a lot of dust during the sand making process. If the dust content is too high, the usefulness of the manufactured sand will be severely limited, so there is still a need for Treat the dust contained in the manufactured sand.
At present, there are two main methods for the treatment of machine-made sand dust in China, one is dry treatment (that is, dry sand making); the other is wet treatment (that is, wet sand making). Wet sand making mainly uses a sand washing machine to wash the dust with water. There are strict requirements on the equipment site of the equipment, that is, the sand making production line must have abundant water resources. For dry sand making, powder separator, coarse and fine powder separation machine are used, combined with bag filter and other equipment and air separation technology is used to recycle the dust contained in the sand making machine. Unlike wet sand making, dry sand making does not require water for washing.
