Measures of Energy Conservation and Emission Reduction of Sand Maker

The vertical shaft impact crusher can also be called sand making machine, which is researched, developed and manufactured with the stone impacting stone principle and technology. This machine mainly uses the impacting principle to crush the large stone into small one and even into sand. There are mainly three methods that can be used for conserving energy and reducing emission for the sand maker. 1. The tension force of the driving triangle rubber belt should be adjusted to be proper in order to make sure that the load force of the triangle rubber is equal. When the machine is driven by double motors, the triangle rubber on both sides should be grouped and selected in order to try to make the length of every group is the same. 2. The vertical shaft impact crusher adopts mobile car used lubricating grease, and after four hundred hours of work, the workers should add proper amount of lubricating oil and after two thousand hours of work, the workers should open the main axis spindle mechanism and cleanse the bearing. The workers should change new bearings after 7,200 hours of work. The upper bearing of the principal axis is the movable part and the lower bearing is the fixed part and after the installation, the workers should pull the belt conveyor to see if it is able to move flexibly. 3. Regularly stop the machine and open the observation door in order to observe the abrasion condition inside the sand maker. The workers should pay attention to the abrasion degree of the central material feeding pipe, cone cap, the upper and lower lining board of the impeller, the surrounding baseboard and if they are abraded, they should be timely changed or repaired. It is forbidden to open the observation door during the working process of the crusher in order to avoid danger.

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
