Our company has the ability to design and manufacture, at the request of the customer, a drying drum for drying ores with a capacity of 1 ton per hour to 35 tons per hour. If higher productivity is required, our company is ready to offer modular ore drying complexes with a capacity of 70 tons per hour to 500 tons per hour.


Our drying drums for drying ores can be aggregated with heat generators operating both on gaseous fuel (natural gas, propane-butane mixture), liquid (diesel fuel, fuel oil, various synthetic boiler / furnace fuels, coal-water fuel), solid (wood-burning furnaces, coal furnaces , multi-fuel (operating both on pellets, briquettes from wood raw materials, agricultural raw materials, and on wood chips, firewood, coal - brown, anthracite, coals of grades D and G), pulverized coal injection installations).

Heat generators operating on natural gas are the easiest to maintain and technologically advanced. They are fully automated and do not require constant monitoring. The only drawback is the cost of natural gas in Ukraine. The cost of drying is 1.5-3 times higher than when working on solid fuels or liquid (synthetic furnace fuels, pyrolysis products of tires, oils). The most significant savings can be achieved using solid fuel heat generators. Among them, the best price / cost ratio * technological effectiveness is possessed by a pulverized coal-fired heat generator. And the most economical will be a heat generator operating on briquettes from sunflower husk and also on brown coal (pieces of 20-100mm). However, they have significant disadvantages.


  1. 1. So, for example, all heat generators require a stoker for timely fuel supply and ash removal. When using a wood-fired heat generator, it is necessary to constantly monitor the moisture content of the incoming firewood, otherwise it will be impossible to achieve the required heat output for the drying process. It also requires a permanent large warehouse for firewood and a firewood preparation area (unloading, sawing, sorting). For example, for a heat generator with a capacity of 1-1.5 MW, the required amount of firewood is 25-37 cubic meters. per day, which is equivalent to 1 truck. Thus, it turns out that, depending on the wishes and needs of the customer, the type of heat generator used is not always obvious. Sometimes it is more expedient to install a heat generator that runs on diesel fuel, or on natural gas and not have unnecessary trouble.

  2. 2. Also, in addition to the heat generator, for the operation of the drying drum, a smoke exhauster is needed, which ensures the suction of the necessary air for combustion, its passage through the drying drum, cyclone and the evacuation of moisture evaporated from the ores. For each capacity in tons per hour, taking into account humidity at the inlet and outlet of the drying drum, rheological properties of ores, porosity, etc., a smoke exhauster is specially calculated, designed and manufactured with the required parameters.

  3. 3. The third necessary element for the correct conduct of the ore drying process is the presence of a dust-precipitating cyclone. Dry ore, especially ore concentrates, is a highly dusty material and therefore requires a dust deposition system. The cyclone parameters depend on the performance of the drying drum, the amount of moisture removed from the material, the type of heat generator. Therefore, in each individual case, depending on the configuration, we select the cyclones individually ..

When purchasing equipment from our company, we provide all the necessary documents - a data sheet, an operation manual, installation and aggregation schemes with feeding and unloading material. We also provide any feasible advisory assistance in the preparation of project documentation for coordination with government agencies.
