Does dry sand making need a sand washing machine?
Dry sand making is developed on the basis of wet sand making technology. Compared with wet sand making, dry sand making is not limited by water source and environment, which is more convenient for production and operation and lower in sand making cost.
Dry sand making process: vibrating feeder-- jaw crusher-- cone crusher/ impact crusher--sand making machine--vibrating screen--sand washing machine--finished material pile.
Among them, the jaw crusher is used for the coarse crushing of raw stone to break large materials to medium particle size; Cone breaking and impact breaking are used for medium and fine crushing links. Cone breaking is suitable for the crushing of hard stones such as basalt, granite and river pebble. Impact breaking is used for the crushing of medium and low hardness stones such as limestone and bluestone; The finely crushed stone is directly processed into a sand machine for further fine crushing and shaping to produce machine-made sand that meets the particle size requirements; After being cleaned and dehydrated by the sand washer, it is sent to the finished product pile.
In the application of machine-made sand, three main indicators have attracted much attention: powder content, crushing index and fineness modulus. In the production process of machine-made sand, a small amount of stone powder with a particle size of less than 0.08mm will inevitably be attached. According to the quality standard of natural sand, particles smaller than 0.08mm are defined as mud, and the content limit of mud is very strict.
Therefore, sand washing is a necessary step in dry sand production. Sand washing machine is specially used to clean and separate stone powder, soil and other impurities from sand and stone, so as to improve the quality of finished sand and stone. It is the equipment matching with sand making machine
SMMVIK XSD series sand making machine is developed by using domestic and foreign technology and combined with the actual situation of the sand and gravel industry. It is a wheel-bucket sand washing equipment used in conjunction with the sand making machine. It is widely used in the washing, grading and impurity removal of fine-grained and coarse-grained materials in metallurgy, building materials, hydropower and other industries. It is suitable for construction sand and road construction sand. The general dry sand production line is equipped with such sand washing machine equipment, and the application effect is good.
