Related knowledge about slurry pump 1- Slurry and its characteristics
Introduction
About slurry pump, we must know what's slurry, and its characteristics. Slurry actually refers to a mixture of liquid and some solids that are insoluble in the liquid. Factors such as the type, size, shape and content of solid matter comprehensively determine the physical properties and flow characteristics of the slurry.

Definition of slurry:
Slurry actually refers to a mixture of liquid and some solids that are insoluble in the liquid. Factors such as the type, size, shape and content of solid matter comprehensively determine the physical properties and flow characteristics of the slurry.



The main characteristic parameters of slurry that need to be described in slurry pump selection:
Type of solid matter True specific gravity of solid matter----S
Solid particle size distribution----such as median particle size d50
Solid content----weight concentration Cw; volume concentration Cv
Liquid type Liquid specific gravity----Sw viscosity of slurry
Slurry temperature
The PH of the slurry - PH value and what kind of acid or alkali.



In engineering applications, slurries are usually divided into two categories based on their different characteristics: homogeneous slurries and non-homogeneous slurries.

Homogeneous slurry: refers to those solids in the slurry whose particle size is so fine that these solids will not settle even in a static state. This type of slurry is very small abrasive, but with concentration changes in viscosity will show large changes in macroscopic viscosity, so be very careful in selection.

Heterogeneous slurry: Solid particles are relatively coarse and will precipitate in a static state. Coarse particles increase the abrasiveness of the slurry. Usually, most of the slurries we encounter are non-homogeneous slurries.
