PCL direct impact crusher, commonly known as the Sand. Is the crystallization of company experts for many years to develop the mining machinery and equipment wisdom and the right decisions, is an internationally advanced level of high-energy low-power devices, and plays an irreplaceable role in the performance of thin broken equipment in a variety of ores, is the most line effective, practical and reliable gravel machine. Company since the 2001 production of Sand in the national market has achieved excellent market share, to perfect product performance, the trust our customers to win domestic and foreign customers to its shores. This product is widely used in the ore, cement, refractories, aluminum where the soil clinker, emery, glass raw materials, mechanisms, building sand, stone and various metallurgical slag and other industry. 
 Note: the call for vertical impact crusher, China Building Materials Industry Association China authorized by China Association of gravel led the development of the industry standard of Sand is also scheduled for the vertical impact break. The vertical impact crusher is a new type of device it works American Paman Le, in Europe and the United States has a variety of products, product names vary, often referred to as vertical impact crusher in China such equipment has been There are 30 years of history originally used for crushing hard ore in the mines. 1988 German Martin Stan Kou off the company for the first time the DAVID vertical impact crusher to the cement plant to cover mosaic and original cement mill combination is better. 
 Sand Uses: 
 Sand in this series applies to soft or medium hard and extremely hard materials broken, plastic, widely used in ore, cement, refractories, aluminum where the soil clinker, emery, glass raw materials, mechanisms, building sand, stone and kinds of metallurgy slag, especially for silicon carbide, carborundum, sintered bauxite, Misa high-hard, extra hard, and a higher efficacy of the production of corrosion-resistant material than other types of crushers. 
 In the engineering field, the mechanism of sand, cushion material, asphalt concrete and cement concrete aggregates an ideal production equipment. 
 In the mining industry, widely used in grinding the preceding process, it can produce large amounts of iron ore fines to reduce the high cost of grinding load. 
 This series Sand excellent low wear characteristics, the device used in high abrasive and secondary disintegration broken production. In addition, the product of zero pollution, impact crusher function well adapted to the range of production capacity in the production of quartz sand in the glass and other high-purity materials, 10-500t / h impact crusher to fit almost Any production requirements. 
 Sand work principle: 
 Material from the hopper into the sand making machine, the material is divided into two parts by the sub-feeder, in part by the middle of the feeder into the high-speed rotation of the impeller, the impeller being rapidly accelerated, the acceleration of up to several hundred times the acceleration due to gravity, and then 60-70 m / sec from the impeller three uniform flow within the projectile out, first with self-closing down around the feeder part of the material impact crushing, and then with the impact to support vortex cavity lining materials, material lining rebound in oblique impact on the top of the eddy chamber, but also to change its direction of motion, deflected downward movement of material emitted from the impeller to form a continuous material curtain. Such a material whirl crushing chamber by two and even repeatedly crushing effect on the probability of impact, friction and grinding. The broken material is discharged from the lower part of the discharge opening. The whole under the crushing process, the material of mutual self-impact crusher, not in direct contact with the metal components, but the material lining the impact, friction and grinding, which reduces the angle of pollution, to extend the time of mechanical wear. Ingenious airflow inside the whirl chamber circulation, eliminate the dust pollution. 
 Sand performance characteristics: 
 A simple structure, the use of low cost since the strike crusher; 
 2 unique bearing installation and advanced spindle design, this machine has the characteristics of heavy-duty and high-speed rotation. 
 With crushing, coarse features; 
 (4) high reliability, tight security device to ensure that equipment and personal safety; 
 Smooth operation, work noise, energy efficient, high crushing efficiency; 
 Material moisture content, moisture content up to about 8%; 
 Wearing parts, low loss, all wearing parts are made of high quality wear-resistant materials, long life. A small amount of wear parts for extra hard wear-resistant material made of small size, light weight, ease of replacement parts. 
 8 vortex chamber internal air circulation, dust pollution. 
 Impeller and whirl crushing chamber materials lining significantly reduce the wear and tear costs and maintenance workload. The production process, the stone can be formed to protect the bottom, the body no wear and durability. 
 10 Installation is diverse, mobile installation. 
 11 cubic shape, packing density, the iron pollution. Can be used for stone shaping machine.
