Who would have thought that sand everywhere would also "famine". The seemingly inconspicuous sand and gravel is the most indispensable and irreplaceable material for infrastructure construction, including construction, roads, bridges, water conservancy and hydropower, and other major constructions that are closely related to human survival and development. Gravel. It is understood that the annual consumption of sand and gravel in China is more than 20 billion tons, accounting for about 50% of the world. One side is lack of production capacity, and the other is strong demand. It is not surprising that there is money to buy sand and gravel, waiting for a few kilometers in line to pull cargo, and prohibiting the transportation of sand and gravel. The shortage of sand and gravel has unearthed a major opportunity, that is, machine-made sand, whether large or small sand factories "rise up". Therefore, some investors once asked, "Can I use an impact crusher to process pebbles?" Senior editor of Longjian Group shares his views with you.

The market for cobblestone sand is large

According to statistics, there are currently more than 200 kinds of ore materials in the mining industry that can be used to produce machine-made sand, including common pebbles, river pebbles, bluestone, granite, etc. Regarding which kind of machine-made sand raw material is better, in general, the proportion of river pebbles and cobblestones is relatively high. Other granites, limestones, bluestones, quartz stones, waste concrete, construction waste, etc. can be used for sand making.

Cobblestone is regarded as a high-quality raw material for producing aggregates of sand and gravel. It is a kind of pure natural stone, due to the relatively hard material. It has also become the main source of machine-made sand, and is widely used in public buildings, villas, courtyard buildings, paved roads, park rockery, bonsai filling materials, garden buildings and other high-level superstructures. Because the pebbles are relatively hard, the choice of crusher is very important. The correct choice of crusher can reduce the wear of wearing parts, extend the life of the machine, and ensure the efficiency of the work. In this regard, Longjian Group recommends that you can choose a vertical impact crusher to crush the pebbles according to the actual situation.

What are the advantages of impact crusher for processing pebbles?

1. Reduce the wear of wearing parts and extend the life of the machine. As we all know, the main chemical composition of cobblestone is silicon dioxide, the hardness of the material, if you are using a hammer crusher, not only for the wearing of counterattack plates and other wearing parts, the output is very low. Relying on the crushing mechanism of the vertical impact crusher and hard materials such as pebbles, it greatly improves the crushing ratio and production, and also reduces the wearing parts to a low loss, extending the life of the machine.

2. High-quality aggregates. In addition to crushing pebbles, vertical impact crusher crushing, rough grinding function, the produced material not only completes a good split cube material more than 90%, the particle size is uniform, with a reasonable level.

3. The crushing force of vertical impact crusher, pebbles, and breaking in the same machine can provide greater capacity. The modular design of the vertical impact crusher can realize the flexible crushing by adjusting the cavity size, and has a wide range of applications.

In summary, Longjian Group has focused on mining machinery for nearly 30 years, and has launched PL vertical shaft impact crusher series products with output of 200-650t / h, high efficiency and energy saving, and stable operation.
