The basic application principle of thickener and thickener is introduced

Thickener (also called thickener) is widely applied in the cyanide cyanide plant medicine and leaching pulp washing equipment.According to the different way of transmission, thickener can be divided into the center transmission and peripheral transmission type two kinds.Center drive type for structural reasons, shoulds not be too large in diameter, is generally less than 15 meters.If the subsidence area is larger, it must be with large diameter periphery drive type thickener, its diameter 15 meters or more.

The specifications of the thickener, the center drive type is generally expressed in the inner diameter of thick pool, peripheral transmission type represented by the diameter of the circular orbit.

The working principle of thickener:

By means of solid particles and the role of its own gravity, and make the clarification and high consistency pulp into density of sediment two parts, this process is called enrichment.

In the process of enrichment, suspended particles in the pulp settling down due to its own gravity.At the moment to precipitation, ore grain sinks in under the action of gravity acceleration, then because water resistance due to the increased rate of ore grain sinks increases, the acceleration decreases gradually, until the water resistance increases to the ore grain weight equal, ore grain sinks acceleration is reduced to zero, so the precipitation particles with a constant speed, the constant speed is called at the end of the sedimentation velocity.

Is concentrated pulp, if the concentration is lesser, particles in the settling chamber can ignore the mutual collision and interference, the settlement of such called free settlement;If the concentration is lesser, interfere with each other when particles sedimentation due to collision and friction between each other and the mechanical resistance is bigger, called interference subsidence at this time.Because in addition to the water resistance, and a mine mechanical resistance between each other, so to intervene subsidence ratio at the end of the settlement is smaller.Because this is what the concentration of middlings was smaller pulp settling quickly, in the concentration of middlings was larger pulp particles precipitate slowly.
