Sand Making Machinery, Sand Making Machines

Brief Introduction to Sand Making Plant: The sand making machinery can also be called sand making plant, and it is one of the most important crushing and sand making equipment. The series sand making machines manufactured by SBM Machinery has superior performance in the sand making production line and it is a highly efficient sand making machine leading the domestic and foreign mining machinery industry. Structure and Application Range of Sand Making Machinery: The SBM series sand making plant is mainly composed by material feeding, material separating, whirling motion crushing chamber, impeller, principle axis, foundation driving device and the motor. With its unique structure, the sand making machines are widely used for medium and fine crushing all kinds of hard and crisp materials such as concrete aggregate in the mining, metallurgy, cement, power station, water conservancy, coal and building materials and other industrial departments. Main Equipment Used in the Sand Making Production Line: In the sand making production line, several equipment will be used such as sand dryer, sand screening machine and sand vibrating screen. Operation Principle of Sand Making Plant: 1. Center Feeding: Raw material falls down into feed hopper, and then enters impellor through central entrance hole. It is accelerated in high-speed impellor, and then is thrown out at speed of 60-75m/s. When hitting impact plate, it is crushed. Final products come downwards though outlet. 2. Ring Feeding: Raw material falls down into feed hopper, and then through ring, it is divided into two parts by material-dividing plate. One enters into impellor through the center of material-dividing plate. The other falls down from outside of material-dividing plate. Material thrown out by impellor at speed of 60-75m/s hits material coming down from outside of material-dividing plate. In this way, material is crushed.

Artificial aggregate production process and advantages and disadvantages

Wool sand making machine by crushing, screening, grinding, washing the resulting sand and gravel. In the absence of natural sand areas, often using artificial aggregate pouring concrete. Artificial aggregate production process are: wool mining, processing coarse aggregate, fine aggregate processing, screening, after washing reserves and transportation. Advantages of artificial aggregate are: ① wool stope nearest arrangements, reduce storage, loading and transport links, saving investment; ② to adjust production mix than the aggregate of all levels make full use of wool, save mining cost; ③ artificial aggregate particle size distribution is good, save cement, fresh surface roughness to increase bond strength, good mechanical properties. The disadvantage is the need to increase drilling blasting, crushing, sieving, washing, sand and other processes, the process is cumbersome, install more equipment and a greater direct costs of the system. Wool sand by crushing, screening, grinding, wa...

Raymond Mill grinding system new advantages

Raymond Mill is a kind of grinding equipment that we commonly use in industrial ultrafine mill . It is suitable for limestone, calcite, marble, talc, gypsum, barite, fluorite, zeolite, manganese ore, ilmenite, phosphorus Minerals, bentonite, starch, kaolin and other stones with a hardness of less than Mohs 7 are ground and used in a wide range of applications, all of which are inextricably linked to its new grinding system. So what technology is applied to the grinding system used by Raymond Mill? 1. The new technology adopts a new vertical roll device. The grinding roller and the grinding ring are always in balance during the grinding process to form a uniform line contact grinding zone. The height of the grinding roller and grinding ring is increased from the original 160 mm to 200 mm, which increases the grinding contact area to a greater extent. 2. The classifier adopts a forced turbine classifier to extend the granularity of the finished product from the original 80-325 mesh range...

New sand maker consolidates infrastructure construction

Since the 18th National Party Congress, our country has been inclined tocontinue to invest heavily in infrastructure to promote economicbooming, which will further expand the market demand for vsi sand making machine and gravelaggregate. In the face of the huge gravel aggregate demand, it isnecessary for gravel equipment R D manufacturer to activelyprepare for high-tech sand making machine to help the rapid development of economy. Sand making equipment is the key to the production of high-quality sandand gravel aggregate, the quality of sand and gravel aggregates directlyaffects the quality of infrastructure works. For a long time, theoverall technical level of sand making is low; facing increasinglystringent technical and quality requirements in the market, China sandmaking machine manufactures require to take active innovation, furtherincrease R D investment on technological application to meet thehigh standards and high demand of the market. Hongxing machine deeply understands...
