Our Quality Coal Products
Backed by vast years of experience and state of the art technology our final product is an output of a rigorious production flow with high standard jigging, filtering and washing technology . we are proud to say you can trust us for clean reliable quality of coal. Choose us for graded subbituminous coal. We produce high-quality coal products for sale and distribution in the over-the-road or OTR trucks to industrial sites.
We process raw coal from our main DAWRO COAL WASHING PLANT (dcwp), located in Dowro Zone, a region known for its rich coal resource mainly lignite and some Sub bituminous.
The plant has a reliable supply of washed coal with a capacity of producing 450,000-500,000 tons of washed coal per year, that replaces the imported coal.
The Washing Plant Technology
The plant uses a Heavy Media Cyclone coal washing Technology. The crushed coal is sent to a mixing box where the coal gets mixed with the magnetite medium of required specific gravity. The coal plus magnetite from the mixing box will be pumped to the Heavy Media Cyclone by a centrifugal pump. The Heavy Media Cyclones will separate washed/clean coal and rejects by density.
After careful analysis of the raw coal, the washing plant which for ETMDSC is designed to integrates two cleaning circuits that cleans the two size fractions and runs on two-unit operations which are categorized as:
“coarse” (– 18 + 1 mm): Heavy Medium Cyclone (HMC) and
fine (– 1.0 + 0.1 mm): Spiral. The calorific values (CV), ash content and suitability of the three product categories obtained from the processing of raw coal:
| Category | CV (kCal/kg) | Ash (%) | Designation | Suitable for |
| 1 | > 5,500 | < 18 | “Clean” Coal | Cement plants |
| 2 | 2500 – 3000 | 40 – 42 | Meddling | Power plants, furnace industry, … |
| 3 | 800 or less | > 70 | Refuse | Tailing Dam |
Our Specification of Washed Coal: The washed Coal can have a calorific values ranging from 4,500 – 7,000 Kcal based on clients requirement.
