Paste Thickener

LDHB high-efficiency paste thickener is based on the traditional vertical flow sedimentation equipment. The structure of the internal feed cylinder is improved, and the efficiency of sedimentation is greatly improved. The plane of the tank body is circular and suspended. It settles into the conical sludge tank at the bottom of the tank under the action of gravity, and the clarified water is discharged from the overflow weir around the upper end of the tank. The overflow port is provided with a scum filter device and a baffle to ensure the effluent water quality, the underflow concentration is up to 70%, and the treatment capacity is 3-8 times higher than that of the conventional concentrator.

How LDHB paste thickener work?

LDHB paste thickener is a solid-liquid separation equipment based on gravity sedimentation. When working, the solid particles suspended in the pulp in the centrum of thickener settle under gravity, and the upper part becomes clarified water, so that the solid-liquid can be separated.

The slurry wastewater with solid content of 2%-15% can be raised to 60%-70% slurry by gravity sedimentation. The upper part of the tank can realize clear water overflow, so as to achieve the purpose of slurry purification and solid-liquid separation.


1. The high-efficiency paste thickener has a slender body, and a flocculant is added during the concentration process to accelerate the concentration process of material settling and overflow water clarification.
2. Using suspension filtration, medium adsorption, precipitation working principle, no purification film, no wearing parts.
3. The tank body is made of high quality carbon steel (or stainless steel, epoxy glass reinforced plastic, etc.) material, which has good strength and corrosion resistance.
4. The cost of the medicament is low, the treatment volume is large, the treatment efficiency is high, and the performance is stable.
5. Small size, small footprint, easy to install.
6. The service life of the whole machine is 10-15 years, with less one-time investment and significant economic benefits.
7. The processing capacity is higher than that of the traditional thickening machine, and the quality of the overflow water can reach the national emission standard.
