Product Description of Ore Powder Dryer
The mining dryer is a high-efficiency, energy-saving drying equipment developed by our company based on the successful experience of similar products at home and abroad and multi-party investigation of potential
Among them, mining dryers are one of our company's main
flagship products. In terms of designing and producing large-scale dryers, we are already at the absolute leading level in China. It is mainly used for drying materials with a certain humidity or particle size such as iron ore, titanium ore, quartz sand and other minerals. The rotary dryer has strong adaptability to materials. It is generally suitable for granular and block materials. It can also be used to dry sticky paste materials or materials with higher moisture content by partially adding materials. materials.
Especially for drying slag, the advantages of mining dryers are large production capacity, wide application range, small flow resistance, large allowable fluctuation range in operation, and convenient operation.
Working principle of mining dryer
The slag is sent to the hopper by a belt conveyor or bucket elevator, and then enters the feeding end through the feeder of the hopper and the
feeding pipe. The inclination of the feeding pipe should be greater than the natural inclination of the materials so that the materials can flow into the mining dryer smoothly. The dryer cylinder is a rotating cylinder, which is slightly inclined with the horizontal line. Materials are fed in through the higher end, and heat carrier enters through the lower end, and contacts with materials in counter-flow. Sometimes heat carrier and materials enter into the cylinder in parallel flow. As the cylinder rotates, the materials move to the lower end due to gravity. When the wet materials move forward in the cylinder, they receive the heat carrier directly or indirectly, so that the wet materials dry. Then, the wet materials are discharged through the belt conveyor or screw conveyor at the discharge end. Send. There is a lifting plate on the inner wall of the barrel of the mining dryer (yellow sand dryer). Its function is to lift the material up and spread it down, so that the contact surface between the material and the airflow is increased. , to increase the drying rate and promote material advancement. Heat carriers are generally divided into hot air, flue gas, etc. After the heat carrier passes through the dryer, a cyclone dust collector is generally required to collect the materials in the gas. If you need to further reduce the dust content of the exhaust gas, it should be discharged after passing through a bag dust collector or wet
dust collector.
The mining dryer has made many technical innovations in the lifting device system and adopted a new multi
combined lifting device, which overcomes the wind tunnel phenomenon of traditional dryers and has high thermal efficiency. , coal consumption
is reduced by about 10%. It is suitable for a variety of combustion furnaces, including high-temperature boiling furnaces, coal-grinding powder-spraying furnaces and
artificial coal-adding furnaces. The large and small transmission gears use pin-replaceable gears, which replace the traditional cast steel gears
, saving cost investment and greatly reducing maintenance costs and time.
