APPLICATION TECHNICAL MANUAL OF XINHAI MINING MACHINERY PRODUCTS ■ THICKENING Updated High-efficiency Thickener Principle The thickener is mainly composed of two major parts including circular thickening tank and rake-type mud scraper: The solid particles suspended in the pulp in the thickening tank is settled by the gravity effect, after that, the clear water is on top, which makes the solid-liquid separation. The slurry deposited at the bottom of the thickening tank is continuously scraped to the center of the tank bottom by rake-type mud scraper and discharged by the outlet, and the clean water overflows from the top edge of the thickening tank. Features 团 集 海 The deaerating tank is added to avoid solid particles attaching to bubbles and settling as parachute phenomena The feeding pipe is installed under the liquid level in order to bring the air when feeding. The feeding sleeve is moved to a lower position and equipped with a receiving plate in order to make the pulp fed fall evenly and steadily and effectively prevent the rolling phenomena caused by the overbottom pressure from feeding. The inner overflow weir is equipped to make the materials flow along the designed route and prevent short circuit phenomenon, by which the depression area is enlarged. The overflow weir in sawtooth shape can reduce part suction phenomena caused by out of level of overflow weir. The linear of rabble blade is changed from slash to curve, which makes the rise of discharging underflow concentration and the improvement of the treatment capacity. 鑫 Application It can be widely used for the treatment of slime, waste water, and waste residue in metallurgy, mining, coal, chemical industry, building materials, and environmental protection departments.

If adding flocculant, the capacity can be improved by 3-6 times. The concrete structure can be adopted if the thickening diameter is greater than φ7m. - 66 -
