High efficiency Rotary Drum Thickener

It is widely used for dealing with slime, wastewater, waste residue in metallurgy, mine, coal, petrochemical industry, building materials, environmental protection department etc.

The structure of rotary drum thickener :
1.Deaeration cell is provided to avoid solid particles attaching to bubbles and settling as parachute phenomena
2.The mineral-feeding pipe is beneath the liquid level lest air to be brought in while feeding.
3.The feeding casing is moved to a lower position and a receiving plate is equipped. Therefore, the fed slurry fall evenly and steadily, preventing rolling phenomena because of the residual pressure from feeding.
4.Inner overflow weir is equipped to have the pulp flow on pre-designed route, avoiding short circuit, enlarging the sediment area.
5.The pattern of the overflow weir is made into indented shape, eliminating part suction phenomena induced by unleveled overflow weir.
6.The rabble blade is changed from oblique lines to curves. So the discharging underflow has higher density, and treatment capacity is enhanced

working principle of rotary drum thickener :

This thickener consists of round thickener and harrow scrapping machine, the solid particles suspend in thickener settling by gravity, the pulp in the upper turn into clean water, so that the separation can be realized. Slime that sediment in the bottom of the thickener is discharged by the harrow scrapping continuously, and clean overflow from the upside.
