Detailed Overview of Coarse Material Washing Machine

Coal washer also named coal washing machine, coal washing equipment is actually a crucial equipment employed in coal processing plants.

Coal Washing Description

Coal with particle size larger than 1mm is ordinarily separated from waste material utilizing a dense medium separation method. This process takes benefit in the density differences in between the coal (generally RD 1.30 – 1.50) as well as the gangue supplies (RD1.75). metso crusher

A stable medium of a known Relative Density is made up, and in the beneficiation procedure the coal floats on top in the medium whilst the gangue sinks to the bottom. This gravity procedure is often sped up by utilising Dense Medium Cyclones.

Magnetite (Fe3O4) is the preferred ferromagnetic mineral made use of to create the suspension required in the beneficiation process. There are a number of reasons for this:

1. Magnetite has a RD 4.9, and can be applied to create stable suspensions from RD1.30 – 1.80 which is the preferred operating range for the majority of Coal Beneficiation Plants.

2. Magnetite is magnetic and hence can be recovered by Magnetic Separators and re-used in the process

3. Magnetite is relatively inexpensive when compared to other high density supplies such as Ferro Silicon (FeSi)

Coal washer overview

Coal washer is an important washing machine in coal washing method. We know, when the raw coals are mined from underground, they need to pass some coal working procedure so that coal can be made use of in our modern life.

Coal washing is an essential pre-process of coal cooking. Coal can divide into raw coal and clean coal. Raw coal is generally utilized as fuel for energy, clean coal or fine coal is employed for coal cooking. marble crusher

Clean coal should be washed with water to sulfur, to impurities and other industrial processes, in order to achieve the criteria used coke. So, coal washer also called coal washing machine plays an important role in this coal processing.
