technical field

The utility model belongs to the field of construction machinery, in particular to a sand screening machine, in particular to a drum type sand screening machine.

Background technique

The drum type sand screening machine imitates the working principle of artificially using the inclined screen to screen sand. It adopts a flat roller screen drum and ensures that the sand is fully dispersed and separated by repeated rolling and sliding in it. However, some concrete sand will be mixed with Some iron filings and other debris cannot be separated by the sand screening machine, which seriously affects the purity of the clean sand after separation. In the past, when some concrete was directly put into the sand screening machine, the spiral stirring device inside could not separate the concrete sand. The large sand inside is crushed, which greatly reduces the sand screening efficiency of the sand screening machine; therefore, it is very important to provide a drum type sand screening machine with a simple structure, easy to use, and capable of pulverizing sand and separating iron filings. necessary.
