Re upgrading of environmental protection: how can tailings be processed into machine-made sand? What crusher is used for tailings crushing?
How can tailings be processed into machine-made sand? What crusher is used for tailings crushing? With the continuous development of domestic economy, the demand for sand and mineral resources is also increasing; Due to the continuous expansion of the mineral processing industry, the number of tailings is also increasing; Usually we say that tailings are one of the products of mineral processing and separation; At present, many people still focus on mining and filling, covering soil to make farmland for the utilization of tailings. In fact, the treatment method of tailings is to make sand from tailings, which has environmental and economic benefits; So, how should we choose tailings crusher and tailings sand machine? How to configure the process flow of tailings crushing sand production? SMMVIK answers:
Introduction to tailings crushing sand machine:
VSI6X series vertical shaft impact crusher (sand making machine): it is a high-performance crushing sand making equipment developed and produced by our engineers after absorbing years of research and development experience and technical concept, and adopting the new four port impeller design structure and special sealing structure to prevent oil leakage of bearing barrel; 6X series sand making machine stone has a number of new sand making and crushing equipment with national patent technology, which has the characteristics of energy saving, long service life, wide application, etc., helping the large sand field gradually move towards large-scale and centralized production, so as to meet the national requirements for environmental protection and production capacity; The equipment is widely used for fine crushing and coarse grinding of metal and non-metallic ores, cement, refractories, abrasives, glass raw materials, building aggregates, artificial sand and various metallurgical slags, especially for medium hard, extra hard and abrasive materials such as silicon carbide, carborundum, sintered bauxite, magnesia, etc., which is superior to other types of crushers.
Process flow of tailings crushing sand production:
The stone is uniformly sent to the jaw crusher by the vibrating feeder for coarse crushing, and the material after coarse crushing is sent to the sand machine by the belt conveyor for further crushing. The finely crushed material is sent to the vibrating screen for screening. The material meeting the requirements of finished product particle size is sent to the sand washer for cleaning, and the finished product is output by the finished product conveyor belt after cleaning; The materials that do not meet the grain size requirements of finished products are returned from the vibrating screen to the sand making machine for reprocessing, forming a closed circuit multiple cycles. The granularity of finished products can be combined and graded according to the needs of users. If dry production process is selected, coarse and fine powder separator and dedusting equipment can be equipped.
Performance characteristics of tailings crushing sand machine:
1. Unique rotor and cavity design, large handling capacity, high sand forming rate, good grain shape, low needle and flake content, and high extrusion density.
2. The self impact and self lining mechanism between materials reduces the contact between materials and metals, prolongs the life of vulnerable parts, and reduces the iron pollution of finished materials.
3. The unique wear-resistant structure and material extend the service life and reduce the operating cost.
4. The special rotating structure makes the equipment run smoothly at high speed. Automatic control system, electric lifting, hydraulic headstock device, anti vibration sensing device and cumulative startup timing device can be selected to ensure the safe operation of the equipment.
5. The ingenious internal air circulation design eliminates the dispersion of dust.
6. With simple structure and convenient operation and maintenance, it is the full embodiment of new technology and new process.
