20t/h (dry ore) stacked high-frequency screening;
the material is Coal tailings, the maximum feed size is 0.5mm; the screening material needs to be recycled: 0-0.1mm (this part of the particles needs to be recycled, which accounts for about the total material 20-30% of the raw material does not contain mud; -0.1mm is classified and transported to the thickener and then finely processed with a shaking table or other gravity machine as well as flotation ; 0.1-0.5mm is classified and sent to the filter press for tailings to be drained; the specific gravity is less than -1
Manufacturing Process: Screen frame main engine: Q345R boiler container plate is used for the vibration part, and the whole steel plate of CNC plasma cutting machine is cut and bent, and tempered after welding to remove internal stress. The connection between the screen box and the funnel, and the screen box and the main vibrating beam adopts HUCK ring groove rivets and imported lock nuts to prevent the possibility of loosening of standard parts. The entire screen is sprayed on the outside, and the internal flow area is treated with natural wear-resistant rubber. There is no ore pulp and steel plate.
20t/h (dry ore) stacked high-frequency screening for Coal tailings with maximum feed size 0.5mm and recycled is 0-0.1mm
tomine's has solved many a issues on steel ball and rod's historical problem of easy brokage, quick wearing and short service life
TOMINE Rubber lined Steel Pipe can be used for a long time under an environment between -50℃ and +120℃,
Copper ore prioritized flotation refers to sorting out minerals gradually according to minerals hydrophobicity difference
