At present, infrastructure construction is in the ascendant, and the amount of sand and gravel aggregates is very large. At the same time, environmental protection efforts are intensified, natural sand and gravel are prohibited from mining, and more are turned to mechanical sand and gravel. So at the same time, many friends asked: "Sandstone can be used to process sand and gravel. Is it?" Here comes the answer to the puzzle.
What is sandstone? It is a sedimentary clastic rock composed of quartz and feldspar. Most of sandstone is composed of quartz or feldspar. It is accumulated in many hilly areas through weathering, corrosion, and transportation. Judging from its components, it is composed of debris and interstitial materials. After processing, the particle diameter is 0.05-2mm. Extracting sandstone from nature is particularly environmentally friendly and meets the requirements of use, so sandstone can be used to process sand and gravel.
According to the diameter of sand grains, it is divided into: giant grain sandstone (1-2mm), coarse grain sandstone (0.5-1mm), medium grain sandstone (0.25-0.5mm), fine grain sandstone (0.125-0.25mm), fine grain sandstone (0.0625-0.125 mm), among the above sandstones, the corresponding particle size content should be above 50%.
Sandstone can be used to process sand and gravel, and is widely used in interior and exterior curtain wall decoration, specification panels, floors; sculpture artwork, pavement and garden construction materials, and special-shaped processing such as relief panels, door covers, window covers, vases, and Roman columns.
Sandstone is processed into sand and gravel. Generally speaking, it needs to carry out technological processes such as crushing, sand making, and sand washing. However, there are many types of sandstone with different hardness. It is also necessary to consider the particle size of raw materials, production requirements, budget, finished products, and sites. Consider designing treatment options.
In addition, before processing sandstone, enterprises must first go through relevant legal procedures, including business license, safety approval, tax registration, etc., choose a suitable factory site, and at the same time meet the convenient transportation and water and electricity conditions, build basic facilities, cement platforms, Workers' dormitories, etc., followed by equipment configuration and sandstone processing process.
Raw material mining: down-the-hole drills, excavators, transport vehicles;
Equipment configuration: jaw crusher + impact / cone + sand making machine + sand washing machine;
Environmental protection device: dust collector, sealing cover, sealing conveyor belt;
Layout and installation: use the height difference of the site floor, configure the equipment of each link, and arrange the belt conveyor, and consider it from a large angle as much as possible, which not only saves investment and operating costs, but also saves space;
Aggregate storage: storage in concrete silo, steel plate silo, and shed storage;
Masterbatch stockpiling→uniform conveying by vibrating feeder→primary crushing by jaw crusher→belt conveyor→intermediate crushing impact/cone crusher (12, 13 stones)→belt conveyor→impact sand making machine for fine crushing (0.05 -5mm sand)→belt conveyor→vibrating screen screening→qualified material→belt conveyor→silo storage.
The price of sandstone processing equipment is uneven in the market, because there are many sandstone processing schemes, and the applicable schemes and processes are different for different production needs, and the prices are not equal, and the production line that is more suitable for the actual situation of the user can save the user Investment and operating costs, but also continuous production, to achieve high returns for users, it is recommended to shop around, but also pay attention to after-sales, if the after-sales is not timely, it will cause an increase in subsequent production costs.
