In the sand production line, it is widely used in the fine crushing and coarse grinding operations of metal and non-metallic ores, cement, refractory materials, abrasives, glass raw materials, building aggregates, artificial sand making and various metallurgical slags, especially in the crushing of medium-hard, extra-hard and abrasive materials such as silicon carbide, emery, sintered baux-vanadium, magnesia, etc., which has more advantages than other types of crushers. The production capacity range of 10-500t h can meet almost any production requirements, and it is an ideal equipment for the production of manufactured sand, bedding material, asphalt concrete, cement concrete aggregate for engineering and crushing in the early stage of mine grinding.

The main alloying elements of alloy steel are silicon, manganese, chromium, nickel, molybdenum, tungsten, vanadium, titanium, niobium, zirconium, cobalt, aluminum, copper, boron, rare earth, etc. Among them, vanadium, titanium, niobium, zirconium, etc. are strong carbide forming elements in steel, as long as there is enough carbon, under appropriate conditions, they can form their respective carbides, and when carbon is deficient or under high temperature conditions, they enter the solid solution in an atomic state; Manganese, chromium, tungsten and molybdenum are carbide forming elements, some of which enter the solid solution in an atomic state, and the other part forms a displacement alloy cementite; Aluminum, copper, nickel, cobalt, silicon, etc. are non-carbide elements and generally exist in solid solutions in an atomic state.

Impact sand making machine is a kind of sand making equipment developed and designed in combination with the needs of China's crushing industry while introducing foreign advanced technology, which is the full embodiment of new technologies, new processes and new breakthroughs in the sand making industry.

Impact sand making machine is suitable for a variety of ores and rocks with different hardness and other high hardness materials. Today, the equipment has become the core machine of the machine-made sand industry and stone forming projects, which is widely used in metal ore crushing, quartz sand production, steel slag treatment and other industries, and its performance plays an irreplaceable role in the sand production of various ores.

During work, the material is sent to the crushing chamber of the WLSA impact sand making machine equipment through the feeder, and collides with another part of the material distributed around the impeller in an umbrella shape under the centrifugal force generated by high-speed rotation, and then collides, rubs and crushes with each other again or many times in the strong vortex formed between the impeller and the shell. After that, it is discharged from the discharge port at the lower part of the sand making machine to complete the fine crushing of the material.

1. Long service life

The core wear-resistant material of the impact sand making machine is made of high wear-resistant and high-temperature resistant materials, which is small in size, light in weight, easy to replace accessories, and has a long service life.

2. High crushing efficiency

The optimized design of the deep cavity rotor of the impact sand making machine increases the output of the sand making material by 30%, and has the function of molding, the product is cubic and the bulk density is high.

3. Easy to operate and maintain

The top cover of the impact sand making machine is lifted by hydraulic system, which is simple to operate, convenient for daily maintenance and inspection, and is conducive to improving the sand production efficiency of the equipment.

4. Thin oil lubrication protection

The spindle bearing of the impact sand making machine is circulated and lubricated by the thin oil station, which can ensure the continuous oil supply of the main engine. During the production process, the stone can form a protective bottom layer, and the body is not easy to wear and tear.

The impact sand making machine has the advantages of small discharge particle size, uniform particle shape, large production capacity, long hammer life, low supporting power, simple structure, stable operation, convenient maintenance and saving investment costs.

The working principle of the impact sand making machine is, to put it simply, the principle of stone on-stone. Let the stones collide with the stones thrown out by the impeller acceleration in the process of natural falling, so as to achieve the purpose of crushing! When the accelerated stones collide with the naturally falling stones, a vortex is formed, and it is broken twice during the return process, so the wear and tear of the machine's impact plate during operation is very small!

Simple structure, low cost, stable operation, high efficiency and energy saving, the material in the impeller and vortex crushing cavity is lined with a large search and concealment amplitude to reduce the cost of wear parts and maintenance workload, effectively solve the problem of "iron pollution" in the crushing process of the original materials such as glass and the problem of "stuck steel" in the process of steel slag crushing, and the ingenious internal air flow self-circulation eliminates the dust dispersion.

Impact sand making machine is also called impact crusher, referred to as impact crusher. It is composed of seven parts: feeding, distributor, vortex crushing chamber, impeller experience, spindle assembly, base transmission device and motor.

Working characteristics of impact sand making machine: simple and reasonable structure, low operating cost. Using the principle of stone onto stone, the wear is small; High crushing rate and energy saving; It has the function of fine crushing and coarse grinding; It is less affected by the moisture content of the material, and the moisture content can reach about 8%; The working noise is less than 75 decibels, and the dust pollution is less; Suitable for crushing medium-hard and extra-hard materials; The product is a cube, with high bulk density and minimal iron pollution.

Brief description of the working principle of impact sand making machine:

The material enters the crusher by the feed hopper, and the material is divided into two parts by the distributor, and one part enters the high-speed rotating impeller by the middle of the distributor, and is rapidly accelerated in the impeller, and its acceleration can reach hundreds of times the gravitational acceleration, and then at a speed of 60-70 meters per second, it is projected out from the three evenly distributed runners of the impeller, and first a part of the material that falls from the self-collection around the distributor is impacted and crushed, and then impacts the material lining layer in the vortex chamber together, and is hit by the material lining layer **, obliquely impacting to the top of the vortex chamber. It also changes its direction of motion, deflects to downward motion, and the material emitted from the impeller channel forms a continuous material curtain. Such a piece of material is subjected to two or more chance of impact, friction and grinding in the vortex crushing chamber. The crushed material is discharged from the lower discharge port.

It forms a closed circuit with the circulating screening system, and the material can be crushed into less than 20 mesh after three cycles. In the whole crushing process, the materials are crushed by impacting each other, not in direct contact with the metal components, but by impact, friction and crushing with the material lining, which reduces corner pollution and prolongs the mechanical wear time. The ingenious self-circulation of the air flow inside the vortex chamber eliminates dust pollution.

The advantages of sand making machine and impact sand making machine are mainly reflected in its characteristics, such as simple and reasonable structure and low operating cost. Using the principle of stone onto stone, the wear is small; High crushing rate and energy saving; It has the function of fine crushing and coarse grinding; It is less affected by the moisture content of the material, and the moisture content can reach about 8%; The working noise is less than 75 decibels (dB level), and the dust pollution is less; Suitable for crushing medium-hard and extra-hard materials; The product is a cube, with high bulk density and minimal iron pollution. The disadvantages of the impact sand making machine are very insignificant compared with its advantages, and the main disadvantage is that some equipment is relatively noisy when working, or because it is not well maintained, its work efficiency will be significantly reduced and other bad characteristics.
