The sand made from river pebble requires a series of treatments such as crushing, sand making, sand washing, and screening to obtain high-quality sand and gravel. It is mainly divided into the crushing stage and the sand making and shaping stage. If you want to obtain higher quality finished sand, you need to wash the sand. This must be based on the actual production situation to determine the type and model of the equipment.
Crushing equipment: The crushing is divided into coarse and fine crushing stages. The material is transported by the vibrating feeder to the jaw crusher for coarse crushing, and then the cone crusher performs secondary crushing to remove the large river pebbles. Processing to a particle size below 50mm is convenient for sand making machine processing.
Sand making machine: After coarse and fine crushed river pebbles, the river pebbles that meet the requirements are produced under the action of the sand making machine, and processed into various specifications such as 0-2mm, 2-5mm, 5-10mm, etc., which do not meet the requirements requested to return to the superior level to be broken again. Fine crushing and shaping: Impact crusher (sand making machine) is a key link in the pebble sand making process of the whole river. As mentioned earlier, the impact crusher is not suitable for processing materials with higher hardness, and the cone crusher is not suitable for processing materials with higher hardness. The material has a large amount of needle flakes, so an impact-type sand making machine is required for an optimized shaping treatment. The impact sand making machine adopts the working principle of impact crushing. After the material enters the crushing cavity from the feed port, it will be quickly impacted on the crushing cavity for impact crushing. At the same time, the material and the material will continue to collide with each other in the crushing cavity. The impact crusher, which combines the working principle of "stone beat iron" and "stone beat stone", has high working efficiency and good grain shape of the finished product.
How do I want to invest in a river pebble machine-made sand production line?
1. Choose the right site: When choosing the site of the sand and gravel plant, consider the location of the sand and gravel production, traffic, water source and power supply, and try to choose a sloped place, so that you can take advantage of the terrain and improve the efficiency of sand and gravel production.
2. Go through legal procedures: To open sand and gravel yard, you need to go through legal procedures and documents. The main procedures and documents include the name verification by the industrial and commercial department, the approval of the safety administration, the business license issued by the industrial and commercial department, the mining license issued by the land and resources bureau, and the environmental protection bureau for environmental protection the assessment and taxation department handles the tax registration certificate.
3. The purchase of equipment should be cautious: the purchase of sand making equipment is the focus of investment, which also relates to whether the sand and gravel plant is profitable. Only by choosing the right sand making equipment can the later production be efficient and effortless. The processing flow of the sand and gravel production line includes feeding, crushing, sand making, screening, sand washing, conveying, etc. The equipment that needs to be used includes feeders, crushers, sand making machines, vibrating screens, sand washing machines, and conveyors. The specific equipment can be equipped according to the actual production situation of the sand and gravel plant.
4. Accurately inspect the sales of finished sand: When investing in a sand and gravel plant, there is another important task to investigate the sales of finished sand. If the sale of finished sand is not good, the later sand and gravel plant may not get high profits. The market of the finished product depends on the quality of the finished sand, and only high-quality sand has a better market.
