How to Calculate the Capacity of the Thickener - Xinhai

Xinhai Company produces various kinds of thickeners. So Xinhai can provide you with the suitable model for your choice. The capacity of the thickener is calculated according to the solid quality concentrated per day. Generally, it can be showed with the unit of t/d. Some new mining plants add more settling device due to the large capacity.

where D is the diameter of the particle and η is the absolute viscosity of the surrounding fluid. Δρ is the density difference between that of the particle and its surrounding fluid: if Δρ is positive the particle will settle (see Thickeners), or if it is negative the particle will float (see Flotation).. In practice, the concentration of particles in industrial suspensions is usually ...

Feed Solid Concentration - an overview | ScienceDirect Topics

Synthetic flocculants have an optimum feed-solids concentration for maximising settling flux – or thickener throughput – which is often lower than the solids concentration at which the process upstream of the thickener operates. In these circumstances, dilution of the feed stream will increase the settling rate and reduce the thickener area required for a given duty (Fig. 16.2).

High Rate Thickeners - Solid Liquid Separation

Description. The High-Rate thickeners became popular in the mid 1980's and are relatively newcomers to the sedimentation line of equipment.

Furthermore, they are normally positioned far away from the center of the plant so to allow ...
