The Best 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.

The choice of heat source for drying equipment can be hot air furnace, fluidized bed furnace, etc. The cost of a hot air stove is lower, but it needs to burn coal well and will not produce slag; Fluidized bed furnaces have a relatively high cost and can burn coal. The selection of drying equipment is mainly based on the local actual situation. If it is in a coal production area and the environmental requirements are not strict, a fluidized bed furnace can be used.
