Deep Cone Thickener

Thickener mining, High rate thickeners

LZZG thickener promoted the structure of internal feed tube on the basis of traditional vertical flow sedimentation tank, which greatly increases settling efficiency. The tank is circular, suspended solids settle down into bottom conical sludge tank by gravity, and then clear water flows away from overflow port around the upper tank. The overflow port is equipped with scum filter and baffle to ensure the water quality.

Working principle

Deep cone thickener is a machine that based on gravity and sedimentation which makes solid-liquid separate from each other.The concentration of pulp waste water could be enhanced from 2%~ 15% to 60% ~ 70% by the machine, the clear water is overflow from the upper part of the thickener , so as to achieve the purpose of sewage purification and solid-liquid separation.


1. Automatic cleaning, automatic discharge slurry, solve manual operation;
2. Adopting the working principle of suspension filtration, media adsorption and settling, no purification membrane, no wearing parts;
3. Made of qualified carbon steel (or stainless steel, epoxy glass fiber reinforced plastic, etc.), with good strength and corrosion resistance;
4. Low flocculant using cost, big capacity, high efficiency, stable performance;
5. Small volume, small floor space, easy installation;
6. Service life is 10-15 years, low investment, remarkable economic benefit.
7. The purified water can totally reach to national standard of discharge and can be recycled.
