Mica powder is a kind of nonmetallic mineral with good elasticity and toughness. Mica powder has the characteristics of insulation, high temperature resistance, acid and alkali resistance, corrosion resistance, strong adhesion, etc. It is an excellent additive. So it has many usage, widely used in electrical appliances, welding rods, rubber, plastic, paint, pigment, ceramics, cosmetics, new building materials and other industries.
Microwave Drying Equipment for Mica Powder
Microwave drying equipment for mica powder
Advantages of microwave drying equipment for mica powder：
1.Microwave drying equipment for mica powder has fast heating speed. Microwave heating is the process of making the heated object itself become a heating body without heat conduction. Microwave drying machine for mica powder can simultaneously heat and dry the inside and outside of mica powder. In practical microwave drying applications, when the surface water evaporates, the object will have a temperature gradient from the inside out, making the direction of water migration and heat transfer consistent, which can greatly improve the drying rate.
For example, using high temperature electric heating of 140℃ requires 9060s, which is 10.8 times of 750W microwave drying time and 26.6 times of 1500W microwave drying time.
2.Microwave drying equipment for mica powder has high energy utilization. In the microwave drying system, the microwave drying device is completely closed, each component basically does not absorb microwave, energy loss is small. In addition, microwaves enter the interior of wet mica powder at the speed of light and instantly transform into heat energy. Microwaves directly heat mica powder. The energy saving of microwave drying technology is realized. With the same load, the energy consumption of microwave drying is less than 10% of that of electric heating drying, and 30% of electricity saving compared with far-infrared heating.
3.Microwave drying machine for mica powder has the characteristics of selective heating. Microwaves will be concentrated in areas with low temperatures and high moisture content, mainly moisture is heated. Moreover, the substrate material only has certain temperature rise through heat conduction in the process of moisture emission, with uniform drying effect and good product quality.
4.Microwave drying equipment for mica powder can be instantly use after open. Compared with the conventional method, it needs no preheating, no waste heat, saves energy effectively and improves the production environment.
5.The operation of microwave drying system for mica powder is flexible and convenient. Microwave power is adjustable, transmission speed is adjustable, can meet various production needs of different producers, one machine is multi-purpose, high cost performance, save production cost.
6.Microwave drying equipment for mica powder is an advanced production equipment of environmental protection. In the drying process, it will not produce waste water, waste gas and other substances that pollute the environment. Manufacturers have no waste disposal pressure, and it is easier to be recognized by the society.
application of mica powder
Mica powder microwave drying equipment composition：
The continuous mica powder microwave drying equipment is mainly composed of feeding system, microwave heating system, mica powder conveying mechanism and discharging system. The wet mica powder is transported from the feeding system to the transport belt and enters into the microwave cavity through the mica powder transport system. Under the action of microwave, quickly dry into powder, exhaust gas from the natural air out of the machine.

Drying principle of microwave drying equipment for mica powder：
Principle of microwave heating: when a dielectric is placed in an alternating electromagnetic field, molecules with asymmetric charges are excited by the alternating electromagnetic field to generate rotation. Due to the irregular thermal motion of the original molecules within the substance and the interaction between adjacent molecules, the rotation of molecules is disturbed and restricted, resulting in friction effect. As a result, some of the energy is converted into molecular thermal motion, that is, in the form of heat, and the mica powder is heated.That is, the electric field can be converted into potential energy, and then into heat energy.
