JSC "Uralelectromed" has installed a new drying unit


the Top Pyshma (Sverdlovsk oblast)



In the vitriol plant of JSC "Uralelectromed" (metallurgical complex UMMC) commissioned a new drying setting. Its fundamental difference from the outdated unit that drying of sulphate is suspended in "boiling" layer (the layer of particles, which is passed through the air injection from the bottom).
According to head of the copper sulphate production JSC "Uralelektromed" Vladimir Ivonin, under the action heated up to a temperature of 70-80 ° C air supplied from below the sulfate layer, he quickly relieved of moisture and does not stick together in agglomerates, as so often happened when using the old technology.
- advanced heat and mass transfer are achieved as a result of intensive contact between the supplied air and the product. Cooling and the crystals on the last stage of drying reduces the risk of caking of the product, he said.
Drying of copper sulphate is an integral part of the entire process. Without this operation it is impossible to obtain a finished product of high quality that meets international standards.
the Drying unit consists of an exhaust fan, heat exchanger, dryer, cooler and the most overall part of the bag filter. It is important that the new installation is controlled by an automated system that precisely regulates heating of the air flow in the drying chamber that provides a high quality finished product. All parameters – the operation of fans, air flow and air temperature, the temperature of the sulfate at the exit of drying unit – is displayed on the monitor screen.
