Microwave dryer makes refractory production safe and environmentally friendly

< P > In industry, refractories refer to a class of inorganic non-metallic materials whose refractoriness is not less than 1580 C. They are mainly used in steel, non-ferrous metals, glass, cement, ceramics, petrochemical, machinery, boilers, light industry, electric power, military industry and other fields of national economy. They are essential basic materials to ensure the production, operation and technological development of the above-mentioned industries. The exhibition plays an irreplaceable important role. With the development of industry, more and more refractories are used. In 2011, China's refractory output accounted for about 65% of the world's total refractory output and sales ranked first in the world. For the drying of refractory materials, how to choose the dryer?

Industrial production is usually accompanied by pollution, our living environment has been fatally destroyed, "energy saving, environmental protection" has become the advocacy of the new era industry, microwave dryer electricity, more environmentally friendly than traditional coal burning. Traditional drying equipment, whether it is hot air drying equipment, steam drying equipment, infrared drying equipment or other heating and drying equipment, because the heating depends on heat sources, through radiation, conduction, convection and other ways, by raising the ambient temperature around the material, first increase the surface temperature of the object, and then through heat conduction, make the internal temperature gradient gradually from the surface to the inside. Rise. Because of the poor thermal conductivity of fire-proof materials and the slow heat transfer speed in the object, it takes a long time to achieve the overall drying of the object. At the same time, it is easy to cause the non-uniformity of drying and affect the drying quality of materials. The microwave drying equipment for refractories produced by

Microwave Equipment Co., Ltd. has solved this problem well, and greatly increased the drying speed and reduced the cost. The microwave drying equipment uses microwave to heat the material on the conveyor belt penetratively. There is no heat conduction process during heating. It directly heates the material as a whole. It can raise the temperature of the material to Shangbai within 5 minutes and quickly force out the water pressure inside the anti-inflammatory material to achieve the purpose of rapid drying.

Microwave fireproof material drying equipment generally refers to a new type of non-metallic material drying equipment with good fireproof, thermal shock resistance and chemical erosion resistance, which is used to dry fireproof material at temperatures not less than 500 C. Fireproof materials must have the characteristics of high resistance, poor thermal conductivity and low expansion coefficient. Therefore, the drying of refractories in the production process has always been a major difficulty. The microwave refractory drying equipment

is customized. The size of the equipment is customized according to the volume and quantity of the material to be heated by the user. The power is customized according to the heating speed of the user, ranging from 15 kW to 200 kW. With temperature monitoring control, transmission speed control, lighting, power regulation and other functions, PLC automatic control is an optional function. There are two types of drying equipment, cabinet type and tunnel type.

Tunnel fireproof board drying equipment has the advantages of uniform energy distribution, high field density, fast processing speed, high efficiency and energy saving. Compared with conventional drying equipment, the machine can obtain satisfactory drying effect in a few minutes without any pollution. The treatment temperature is lower than that of conventional process, which has significant effect on improving product quality and has obvious economic benefits. The machine can set heating temperature, heat preservation temperature and microwave power respectively, which can be adjusted linearly.

cabinet equipment has lower relative cost and can be widely used in refractories, metallurgy, powder materials, chemical industry, ceramics and other high energy consumption, heavy pollution industrial fields and fine processing of new materials, as well as light industry, electronics, food, pharmaceuticals, rubber, environmental protection and many other industries.
