Thickener

Mineral Separation Equipment

Thickener

The thickener is a continuous working equipment for thickening and clarification.
Which is mainly used for thickening of concentrate and tailings slurry in wet mineral processing operations; it can also be used for thickening and purification of all solid-containing slurries in industries such as coal, chemical, building materials, water sources, and wastewater treatment.
The solid particles of the processed slurry settle down to the bottom of the tank under the influence of gravity. They are scraped by a continuously rotating mud scraper and collected in a sediment pit at the center of the tank, from which they are transported by a sand pump. The clarified water flows over the overflow weir around the tank and is pumped to a high-level circulating water tank, thus completing the concentration process.

Note 1: NZS-6 is printed with an additional S; every other model carries the NZ- prefix — reproduced as printed in the catalogue.

Note 2: Capacity is expressed in t/d (tonnes per day), not t/h, for every model in this table.

Note 3: A lifting height of "/" indicates that the model has no lifting mechanism, as printed in the catalogue.

Note 4: Drive motors of 2.2×2 kW (NZ-30G and NZ-40) and 4×2 kW (NZ-45A) are multi-motor arrangements, as printed in the catalogue.

Note 5: Total weight is not progressive across the range (for example NZ-18 at 16 t, NZ-20 at 82.6 t, NZ-30Q at 78.2 t against NZ-30G at 31.8 t); the models marked Metal Tank are heavier — reproduced as printed in the catalogue.
