Automatic Rotary Silica Sand Drum Dryer Dry Mortar Machines

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.
