Coal processing industry
CH.E-Industry Group specializes in engineering and technological solutions for enterprises in the coal mining and coal preparation industries.
Our core activities include the design, manufacturing, modernization, and supply of equipment for coal preparation plants, as well as technical support of enterprises at all stages of technological processes — from raw material preparation to dewatering and waste processing.
We carry out process audits of coal preparation plants, analyze existing process flowsheets, and propose solutions aimed at improving production efficiency, upgrading equipment, optimizing technological processes, and reducing operating costs.
Our engineers have practical experience in implementing projects for modernization and technical re-equipment of coal preparation plants, development of new process lines, as well as processing of beneficiation waste and technogenic deposits.
An important area of our activity is the mechanical dewatering of beneficiation products and fine-dispersed waste, including the use of sedimentation and sedimentation-filtering centrifuges. Such solutions allow increasing the yield of marketable product, reducing losses of valuable components, and optimizing waste treatment costs.
We also provide supply, service maintenance, modernization, and overhaul of centrifuges, including equipment from various manufacturers operating at coal preparation plants.
In addition to centrifuges, our company designs and manufactures a wide range of equipment for beneficiation processes, including classification, dewatering, separation, and material handling.
Our solutions can be applied both for modernization of existing plants and for the construction of new coal preparation facilities or technological modules.

Economic and positive effect of implementing our flotation concentrate dehydration solution
Sediment–filtering centrifuges effectively retain even the finest particles of mineral ores, thereby reducing losses
The use of centrifuges allows for the extraction of a greater amount of valuable components from each batch of raw material
Centrifuges ensure high-purity separation and product classification, enhancing quality parameters
Centrifuges are highly energy efficient and easy to maintain
