With the sharp decrease of natural sand and stone, the supply of sand and stone in the market has exceeded the demand. Faced with such opportunities, recycled aggregate from construction waste has become a best-selling product, in construction projects, recycled aggregate from construction waste has gradually become the main engineering material in the market due to the policy restrictions on the exploitation of sand and stone. With the successive development of infrastructure projects, the demand for stone materials and building sand will naturally increase. These building materials need the support of crushers, sand making machines and other mechanical equipment, which provides huge development space and many opportunities for crushing and sand making plants all over the country.
The reason why sand aggregate is popular in the construction market is that there is a strict set of production standards. Limestone and cobble are generally used as raw materials for building sand and gravel, the sand and gravel aggregate production equipment produced by SMMVIK Machinery has great advantages for processing such materials. The supported building sand has uniform particles and high compressive strength, which meets the standard of building sand, and can greatly improve the quality of the building.
The sand aggregate production equipment is commonly known as sand making machine and shaping machine. Our company introduces the new development achievements of foreign authorities and improves the design in combination with the domestic mine conditions, it is the fourth generation of high-performance sand making equipment with world level at present. SMMVIK Machinery has been engaged in the manufacture of sand and gravel equipment for many years, and can determine whether the sand and gravel meet the new standards from many aspects:
The shape of particles, the stone crushed by the crusher shall be cube, the content of needle and flake particles of coarse aggregate shall not exceed 15%, and the angular particles have greater mechanical stability than the circular particles. The size and distribution of particles have a direct impact on the concrete. High distribution accuracy can ensure that the stability and flow value of the concrete are in a better design condition, otherwise the service life of the pavement will be reduced. The consistency of particle composition is very important to maintain the consistency of mineral mixture composition and each technical index. If the particle composition of the mixture changes greatly, it will significantly affect the quality and service life of the pavement. Keep the particles clean, the existence of excessive dust and other harmful substances formed by the crushing operation on the aggregate particles will cause the asphalt mixture to peel off and loosen, thus affecting the durability of the asphalt pavement.
The sand and gravel aggregates produced by SMMVIK Machinery meet the standardization requirements, meet the production conditions of highly standardized sand and gravel aggregates in the market, and can provide high-quality sand and gravel aggregates for various large-scale construction projects. According to the quality requirements of sand and gravel aggregate for construction, the existing processing equipment shall be transformed. The materials produced by the mobile impact crushing station can pass the strict sand and gravel aggregate review procedures.
