Product details
Product Introduction
The microwave mineral dryer is suitable for rapid drying of various minerals such as iron ore, copper ore, manganese ore, lead antimony ore, aluminum ore, etc. The equipment can directly dry the metal oxides in the ore without the need for secondary conduction, with extremely high heating efficiency, energy saving, and no environmental pollution. It is an advanced technologyMicrowave drying equipment.
Generally divided into poor ore, ordinary ore, and rich ore. Sometimes it is only divided into poor ore and rich ore, and there is no unified standard for this classification. The phenomenon of ore impoverishment, where the grade of the extracted ore decreases due to the mixing of waste rock or the loss of high-grade ore, is observed using a portable microscope during the mining process. Ore impoverishment will increase transportation and processing costs, reduce the production capacity and recovery rate of the ore processing department. If the waste rock contains harmful impurities, it will also reduce the quality of the final product. Ore impoverishment is mainly expressed in terms of ore impoverishment rate (the ratio of the difference between industrial ore grade and extracted ore grade to industrial grade, expressed as a percentage).
Characteristics of microwave mineral powder drying equipment:
(1) The drying process of the mineral powder dryer is advanced, using high-temperature rapid drying technology, with high heat transfer coefficient, high thermal efficiency, and high drying intensity.
(2) The combination of high-speed stirring drying and airflow drying can fully disperse viscous materials, greatly increasing the contact area between materials and heat media, which is beneficial for the drying process.
(3) The mineral powder dryer adopts a special scraping device to avoid the phenomenon of material sticking to the wall.
(4) Wide adaptability, simple operation, low maintenance volume, and stable product quality.
(5) The mineral powder dryer is specially designed for drying mineral powder, with adjustable rotating blade angles and shaft speeds.
(6) The upper part of the mineral powder dryer body is equipped with a relatively wet material reflux layer, and the airflow dryer is equipped with special agitators and other features.
The microwave drying equipment adopts non-contact heating, where the microwave directly penetrates the ore and synchronously heats up the material surface and interior without the need for thermal conduction or heat loss. The heating is uniform and rapid; The traditional process uses heat conduction to raise the temperature of the material, which not only takes a long time to work, but also causes temperature differences, affecting the quality of the product. In this process, heat loss also occurs. Therefore, many mining enterprises in China use microwave drying instead of traditional hot air or infrared drying methods, which saves 30% of energy consumption.
The overall appearance of the microwave mineral product dryer is compact, beautiful, smooth, and occupies a small area; It is mainly made of stainless steel plate, which has strong thermal insulation performance, sturdy and strong, and strong corrosion resistance; The application of PLC system and assembly line work only requires 2-3 people to complete the task, greatly reducing labor intensity and saving human resources.
