How many standards can smmvik fine aggregate meet? What are the shape, size and grading of fine aggregate?
Vu system can use cheap and easily available tailings, wastes, construction waste, "stone chips" and "guami stone" as raw materials, and adopt environmental friendly dry process to produce excellent manufactured sand comparable to natural sand. Vu sand meets the sand standard for concrete. It can be used in the matching sand production of mixing plants, dry mixed mortar, cement product plants, aggregate mines, large construction projects, etc. it can meet the huge demand of the market for fine sand. It has excellent value and has won praise from many parties and recognition from the market.
Particle shape: the stone crushed by the crusher shall be cube, the content of needle and flake particles in coarse aggregate shall not exceed 15%, and the ratio of small thickness to large length of needle and flake particles shall be less than 1:3. Angular particles have greater mechanical stability than circular particles.
Particle size and grading: grading is an important characteristic of aggregate, which directly affects almost all the important characteristics of the mixture. Especially for concrete, high grading accuracy can ensure that the stability and flow value of the concrete are in good design conditions, otherwise the service life of the pavement will be reduced.
Consistency of particle composition: it is very important to ensure the consistency of particle composition to maintain the consistency of mineral aggregate grading composition of mixture and the consistency of various technical indicators. 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 and loosen, thus affecting the durability of the asphalt pavement.
Control the particle content of 0.075mm: the particle content of 0.075mm in the water stabilized base course mixture shall not exceed 5% to 7% to improve its anti scouring ability. Coarse aggregate for asphalt surface course shall be less than 0.075mm by water washing method, and the particle content shall not be more than 1% mainly to control the mud content soluble in water.
Smmvik's Vu sand and gravel aggregate system is a global dry-type sand making system. It has been updated and upgraded on the basis of the original dry-type sand making system. It adopts a highly intensive tower type fully enclosed layout and integrates sand making, particle size optimization, stone powder control, grading adjustment, moisture content control and environmental protection. It not only significantly improves the production efficiency, but also realizes the improvement of various indicators such as machine-made sand particle size, grading and powder content, Make the performance of manufactured sand comparable to that of natural sand, and create new opportunities and values for the development of sand, cement and concrete industry chain.
