First of all, the quality of manufactured sand compared with the natural formation of river sand, the gradation, particle size, powder content and other process indicators of manufactured sand are controllable. We can achieve this through the power of modern mechanical technology, and the quality is completely comparable to that of natural sand. Many friends asked whether the hardness of machine-made sand is not enough, you can choose pebbles, river pebbles, granite and other high hardness stones, the hardness of raw materials is enough, and the hardness and strength of the sand will not be poor.
But not all machine-made sands on the market are of good quality, the traditional machine-made sand equipment has problems such as simple crushing and single screening, resulting in high needle-like particles of coarse aggregates, large porosity, and significant quality fluctuations. Therefore, the choice of machine-made sand equipment is also very important, so how do we choose sand-making equipment?
1. According to the actual production situation, the equipment shall be reasonably selected, at present, 5X series sand making machine and VSI series sand making machine, which are widely used in the industry, have a good reputation. At present, due to strict environmental protection control, VU floor type sand making system is also concerned by customers. This system is fully sealed production, which is more environmentally friendly, but the investment capital is also larger, which can be weighed according to its own situation.
2. Many investigations were conducted to select manufacturers with good reputation and strength. Many customers considered the price of equipment in the early stage. In fact, equipment operation and after-sales service are more important in the later stage. The quality of equipment must pass the test, if normal production is delayed due to equipment problems, the loss is also great.
Therefore, if you choose an equipment type in the early stage, you must do a good job of inspection. You can go to the factory and production site for on-site inspections to see the strength of the manufacturer and the operation of the equipment with your own eyes.
