7 Application Fields You Need to Know about Sand Making Machine

Author: Xiaomo Lin

Sand making machine is a kind of production equipment, widely used for fine crushing of various ores. Sand making machinehas replaced hammer crusher, roller crusher, rod mill and other traditional equipment and become the mainstream equipment in the sand making industry.

Sand making machine is widely used in the medium and fine crushing fields of various ores, cements, refractories, bauxite clinker, emery, glass raw materials and other hard and extra hard materials. It is widely used in the crushing of machine-made construction sand, stone and various metallurgical slags, and has high output efficiency compared with other types of crushers.

  1. Artificial sand made from river pebbles, rocks (limestone, granite, basalt, diabase, andesite, etc.), ore tailings, corundum, talc, olivine, feldspar, fluorite, and stone chips.
  2. Production of construction aggregate, highway pavement fabric, cushion material, asphalt concrete and cement concrete aggregate.
  3. The fine crushing process in the front grinding stage of the mining industry, and the crushing of materials in building materials, metallurgy, chemical industry, mining, refractory, ceramics, cement, abrasives and other industries.
  4. High abrasiveness, secondary disintegration and crushing, desulfurization, steel slag, construction waste crushing and other environmental protection projects in thermal power and metallurgical industries.
  5. Production of glass raw materials, quartz sand and other high-purity materials.
  6. Water conservancy and hydropower, high-grade highways, expressways, high-speed railways, passenger dedicated lines, bridges, airport runways, municipal engineering, machine-made sand production and stone shaping of high-rise buildings in the engineering field.
  7. Fine crushing and coarse grinding of iron ore, copper ore, gold ore, wood ore, lead zinc ore, tungsten ore, manganese ore and other kinds of very hard, medium hard and abrasive materials.

Working principle of sand making machine

The materials vertically fall into the high-speed rotating impeller from the upper part of the machine. Under the action of high-speed centrifugal force, the materials distributed around the impeller in the form of an umbrella with the other part produce high-speed impact and crushing. After the materials collide with each other, the materials will form eddy currents between the impeller and the casing for multiple times of mutual impact, friction and crushing. The materials will be discharged directly from the lower part, forming a closed circuit for multiple cycles, It is controlled by screening equipment to reach the required particle size of finished products.

Based on the principle of stone beating, it features small wear, high crushing rate, energy saving, fine crushing and coarse grinding, less affected by the moisture content of the material, up to 8% of the moisture content, less working noise than 75 decibels (db level), less dust pollution, and is suitable for crushing medium hard and extra hard materials. The product is cubic, with large bulk density, low iron pollution, small impeller self lining wear and convenient maintenance.

Performance characteristics

  1. The structure layout is reasonable, and there are two inspection ports on both sides of the crushing chamber, which is convenient for inspection and maintenance;
  2. Stable operation, low working noise, high efficiency and energy saving, high crushing efficiency;
  3. Dry and wet materials can be ground and finely crushed without blockage;
  4. The impact liner and impact block are made of wear-resistant materials with long service life;
  5. The airflow inside the vortex chamber is self circulating, and the dust pollution is small;
  6. Various installation methods, movable installation;
  7. The finished product has small particle size, good particle size and low iron pollution

Future development trend of sand making machine

With the development and progress of science and technology, the requirements of economic construction on industrial automation are getting higher and higher, and new requirements are put forward for operation technology and sand machine equipment, which play an increasingly important role in the field of national economy. The competition of sand machine is becoming increasingly fierce, and the mining equipment with high automation, intelligence, multi-function, high efficiency and low consumption is increasingly favored by the industry.

In recent years, compared with the traditional sand making machine, the new sand making machine produced by the company has the characteristics of simplicity, high productivity, better supporting and more automation in terms of performance. The future sand machine will coordinate with the trend of industrial automation to improve the overall level of mining equipment. New intelligent equipment, such as high intelligent numerical control system, encoder and digital control components, power load control, etc., have been widely applied to the sand machine equipment, making the equipment users more independent, flexible, correct, efficient and compatible in the operation process.
