How to Calculate the Capacity of the Thickener
Widely used in the factory of metallurgic, mining, coal and so on. Thickener can increase the concentration of solid particles, and after the settling work, the overflow can meet the requirements to be discharged directly. 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. For example, flocculant, whose capacity can be showed like t/h.
The capacity of the thickener is closely relate to its own specific parameters, which includes the diameter (generally put the innermost edge of the work area as the standard), the depth, and size of the settlement. These three factors have a series realationship with thecapacity of the thickener. The bigger the diameter is, the more solid particles they settled. So the bigger the diameter is, the large the capacity it has. Such as the peripheral transmission thickener.While the depth does a little effect on the process capacity, and the concentration of the overflow becomes lower as the depth becomes higher, and the stratification becomes more obviously. So the depth only affect the turbidity of the overflow. The settling area refers to the size of the surface in which the material settled down on. This parameter depends on the inner diameter and the taper. The larger the size is, the more the particles settled and the greater the capacity is. With the settled solid particles accumulated in the bottom of the tank, the rake-type scraper contributes to pushing them into the end of the discharging device, and complete the separating work of solid and liquid. Attentions must be paid to the parameters of the scraper, for example, if the speed is fast, the settling work would be unstable, if slow, it would cause that the mineral deposition is too thick, and could not be scraped out timely.
