The screening system can use a single stage linear vibrating screen or a grading screen, and some manufacturers have added a vibration crushing device to crush the screened coarse sand and recycle it. The key points for selecting the screening system are: based on the actual sand selection, if ordinary river sand is used and there is no crushing device, then a regular linear vibrating screen is sufficient. If stone powder needs to be used, it is best to use a drum screen.

The drying system is a core of the entire mortar station and a key point in determining overall production efficiency. At present, single drum dryers have been gradually phased out because they not only occupy a large area but also have high coal consumption, and the only benefit is convenient maintenance. With the maturity of three tube dryer technology, the mainstream is using three tube dryers. The main manufacturers of three tube dryers include Xuzhou Tiandi Heavy Industry, Shanghai Shanshui, and others. The overall production efficiency of the three tube dryer is divided into series 20, 30, 40, 50, 60, etc. It refers to the dry sand production per hour. Generally, a production capacity of 25-28 tons can be achieved by mixing 30 tons, which can produce 35-40 tons of mortar.
