From the early 1960s, China had a traditional dry method of sand making process. Due to simple equipment, low production capacity and serious pollution, it was soon replaced by the wet sand process that mainly used the rod mill. Because of the high consumption of steel, large consumption of water, high energy consumption, high investment cost and use, and do not solve the problem of environmental pollution, a lot of sand making manufacturers began to introduce advanced sand making equipment from foreign. Hongxing machine continuously increases the technological transformation and investment of research to upgrade the earliest vertical shaft Impact crusher(PCL series sand making machine). The high efficiency sand making equipment with the world s advanced level was designed by the experts from Germany and combined with the working conditions of Chinese.
The equipment consists of a spindle, crushing chamber, engine, transmission, rotor, automatic control system, lubrication system and steel structure part. The easier wear parts such as: rotor matrix, throwing hopper, dividing trays, etc. are using the wear resistant and impact resistant alloy material. It has the advantages of long service life and easily be replaced. The new type of sand maker is used for half dry method of sand making process; It also thoroughly changes the traditional sand making process which has the disadvantages of high energy consumption, high water consumption and dust pollution. The new kind of sand making process solves the problem that the finished sand has the stable quality. The content of flakiness in the gravel aggregate is very less; the grain shape is plump with good level. The technical index, fineness module, powder content and moisture content of the finished sand all meet the requirements of the concrete aggregate system; It will bring some major change to aggregate production. As a result of adopting the advanced lubrication and control system and the scientific concept of design, the equipment has the following advantages, such as: high reliability, the big broken ratio, high processing capacity, and the even gradation. From the perspective of production capacity and the effect of finished sand, it can completely replace the rod mill to meet the requirement of hydropower project construction.As the professional manufacturer of complete sets of mining machinery, such as rotary dryer, Henan Hongxing is always doing the best in products and service. In recent years, along with the construction of high speed railway, highway, municipal construction, water and electricity engineering, artificial aggregate becomes the main material of concrete aggregate system, the production equipment is constantly updating, and the sand making process is more advanced.
