ADVANTAGES OF MACHINE-MADE SAND

                ADVANTAGE

01/Abundant Sources of Raw Materials for Machine-made Sand

Machine-made aggregates are suitable for processing all kinds of material sources suitable for building materials, and are less affected and restricted by the material source. Machine-made sand processing materials include limestone, river pebble, granite, basalt, diabase, sandstone, shale, bluestone, quartz stone, various tailings, etc. There are a large number of metallic and non-metallic ores in my country. About 20% of the tailings are produced in the process of mining and beneficiation. A large number of tailings have not been reasonably utilized. About 10 billion tons of tailings have been accumulated in large quantities, which occupies land and causes environmental pollution, and if properly sorted and processed, many tailings can be made into artificial sand. The technical content of the crushing and screening machine used in production is also improving, which provides a technical guarantee for the production of high-quality concrete aggregates that can meet various requirements.

02/Mature Technology and Stable Quality finished machine-made sand

In recent years, with the rapid development of aggregate production technology, the processing technology of machine-made aggregate has become more and more mature, especially the technology of machine-made sand. There are various process combinations to produce finished sand with different requirements. The crushing, screening, and shaping processes of machine-made aggregates are becoming more and more mature, laying a good foundation for the stable quality and reasonable gradation of aggregates. Compared with natural sand, machine-made sand has better particle shape and reasonable gradation. It plays an irreplaceable role in high-rise buildings and other key engineering fields where natural sand cannot be used.

03/Considerable Scale and Controllable Management sand making system

                            The machine-made aggregate processing plant relies on the mines developed in the medium and long term, which builds large-scale, standardized and green processing workshops, realizing the production mode of centralized management and solidification mode, and bringing huge economic and social benefits.

                        Machine-made sand can be widely used in concrete and dry-mixed mortar products. Sand (yellow sand, quartz sand, limestone, dolomite, etc.), stones, cement, and industrial waste (fly ash, furnace slag, slag, etc.) are the basic components of concrete and dry-mixed mortar. Concrete and dry-mixed mortar prepared from machine-made sand is far superior to natural sand products in terms of anti-permeability, frost resistance, durability, and corrosion resistance. The application of machine-made sand in construction aggregate mainly includes highways, railways, bridges, high-rise buildings, water conservancy and hydropower, airport construction, and other projects.

PRODUCTION PROCESS

                PROCESS

  • The raw materials are transported by the vibrating feeder to the jaw crusher for preliminary crushing, also known as primary crushing.

  • The large stones are crushed to medium size at one time, and then the impact crusher or cone crusher is used for secondary crushing. The materials crushed by the impact crusher or cone crusher are screened on the vibrating screen, and the materials that do not meet the particle size requirements are returned to the impact crusher or cone crusher for re-crushing, forming a closed loop, and the materials that meet the particle size requirements enter Impact sand making machine for shaping and crushing.

  • The materials coming out of the impact sand-making machine are screened by the vibrating screen, the materials larger than the set particle size are returned to the impact sand-making machine for cyclic crushing, and the materials that meet the set particle size are transported to each finished product pile by the belt conveyor.
