Mining Dewatering Screen

The mining dewatering screen is a dewatering unit designed for washed minerals. It reduces the moisture content of the material to 10%~25% through vibratory separation, producing semi-dry material that lightens the load on the subsequent drying process. The pre-dewatered material is then dried by a dryer to ensure its moisture content meets the Raymond mill's feed requirement (<6%).

Features and Advantages of Mining Dewatering Screen

Efficient Dewatering: Achieves rapid solid-liquid separation of washed minerals through high-frequency vibration and screen plate filtration, reducing material moisture content to 10%–25% to form semi-dry feedstock.

Energy Saving and Consumption Reduction: Efficiently removes most free water through pretreatment, significantly lowering the energy consumption and duration of subsequent drying processes.

Prevention of Adhesion: Works in coordination with the dryer to ensure the moisture content of materials entering the mill is below 6%, effectively preventing adhesion and clogging issues in the Raymond mill caused by wet materials.

Stable Operation: Prevents highly moist materials from directly entering downstream equipment, avoiding caking and wall adhesion inside the dryer, thereby ensuring the stable operation of the Raymond mill system.

Working Principle of Mining Dewatering Screen

Uniform Distribution: The washed mineral slurry is evenly distributed on the screen plate via the feed box, ensuring uniform material distribution across the screen width and preventing local accumulation.

Solid-Liquid Separation: Vibration motors drive the screen box in high-frequency reciprocating motion, rapidly separating and discharging free water from the slurry to achieve solid-liquid separation.

Dewatering and Discharge: Solid particles undergo vibration dewatering along the inclined screen surface, with semi-dry materials of 10%–25% final moisture content discharged from the outlet, while the separated wastewater is collected for potential reuse.
