Is the quality of finished cobblestone machine-made sand reliable?
For the development of my country's infrastructure, the amount of sand used is very large. However, the natural sand and gravel are in short supply, and natural resources are gradually depleted. As a result, the popularization and use of sand making machine equipment and the investment in machine-made sand production lines have made up for the sand and gravel gap. The raw materials of machine-made sand are also very rich, such as our common pebbles, river pebbles, limestone, etc., among which pebbles are used more. Cobblestone machine-made sand is of good quality and can be widely used in water conservancy, highway, railway and other fields.
Cobblestone is rich in reserves in my country. It is a kind of natural stone, which has been honed by the impact of mountain torrents and the continuous scouring of running water. High hardness and strong compression resistance. The cobblestone aggregate prepared by the sand making machine has the advantages of wear resistance, corrosion resistance, good particle shape, reasonable succession, and adjustable fineness.
The advantages of cobblestone for preparing sand and gravel aggregate are: first, in terms of material characteristics, cobblestone is not only high in hardness, but also non-toxic and tasteless, and has good wear resistance, which is a good construction sand material; in addition, cobblestone does not need blasting, and the mining difficulty is low , rich in resources, low price of raw materials, and generally speaking, the operating cost is low; then, the sand made of pebbles is cleaner, the grain shape is good, and the selling price is relatively high.
The combined production line of the crusher and the sand making machine processes pebbles with excellent quality. It is a good raw material for machine-made sand. Whether it is crushed into stones or sand, the finished product is hard and compressive, and can basically meet the sand standards for the construction industry. The ideal green sand making raw material can be selected.
1. The cobblestone has high hardness, and the sand produced has high hardness, compression resistance, wear resistance, corrosion resistance, and is comparable to natural sand.
2. The discharge particle shape is good, the sand making machine has its own shaping effect, the gradation is well-proportioned, and the sand output specifications are adjustable, and the fineness modulus control is convenient.
3. The finished particles are of good quality, without cracks and fine lines, and conform to the industry standard for construction sand.
