In recent years, as an irreplaceable material, sand and gravel aggregates have been in short supply, and machine-made sand has gradually replaced natural sand. With the promulgation of national policies, under the new situation, the quality requirements of machine-made sand continue to increase, and high-quality stone materials, machine-made sand equipment and sand-making technology are more important to sand users. So which stone is better for sand making? What should I pay attention to when choosing a sand making machine?
Which type of stone has better sand making effect?
At present, there are many types of stones that can be used to make sand in the sand and gravel industry. For example, cobblestone, granite, basalt, limestone, dolomite, calcite, tailings, construction waste, etc. can be used to make machine-made sand, and different stones are produced. The quality of machine-made sand is uneven. The quality of machine-made sand produced from some hard stones such as pebbles, river pebbles, basalt and granite is relatively better, and it is more in line with the requirements of national construction materials.
Pay attention to the following four points when purchasing a sand making machine:
1. Environmental protection of sand making machine equipment
The country has become more and more strict with environmental protection requirements, has issued a series of environmental protection policies, and shut down a large number of sand and gravel plants that did not meet environmental protection requirements. Therefore, when selecting sand making machine equipment, it must comply with the national green environmental protection concept, and strictly control the pollution of dust and noise. The ecological red line is the bottom line of the sand and gravel industry. Every piece of sand making equipment should be based on green and environmental protection, with the purpose of energy saving and high efficiency, to create a green, environmentally friendly, legal and sustainable machine-made sand production line.
2. Equipment quality of sand making machine
The quality of sand making machine equipment on the market is uneven. The materials of the sand making machine equipment largely determine the quality of the sand making machine and whether the machine-made sand project can run stably for a long time. If the quality of the purchased sand making machine is poor, it may fail frequently during use, which will affect the production efficiency of machine-made sand and delay the construction period of the production line.
3. The reputation of sand making machine
The reputation of the sand making machine manufacturer reflects the quality and reputation of the sand making machine. The reputation and reputation of the sand making machine can help users understand the sand making manufacturer in the early stage. The well-reputed sand making machine manufacturer will know the quality of the equipment. Guaranteed, the production technology is more professional. Therefore, when purchasing sand making machine equipment, users can consult the manufacturer, visit the sand making machine or production line site, visit the site, and judge the quality of the sand making machine.
4. After-sales service of sand making machine
The after-sales service of the sand making machine is the guarantee for the quality of machine-made sand in the future. After-sales service is a very important point. Generally, the formal sand making equipment manufacturers have established a professional team of installation technical engineers. The after-sales service is also easily overlooked by many users. One point, if the after-sales service is not in place, it will be very troublesome if there is a problem with the sand making machine, causing production difficulties for the user.
