Mica is the collective name for mica minerals and is one of the main rock-forming minerals. The crystal form has glassy luster and the flakes are elastic. Its types mainly include biotite, phlogopite, muscovite, lepidolite, sericite, etc. The most commonly used in industry is muscovite, which is widely used in the building materials industry, fire protection industry, fire extinguishing agents, welding rods, plastics, and electrical insulation, papermaking, asphalt paper, rubber, pearlescent pigments and other chemical industries.
Synthetic mica, also known as fluorphlogopite, is produced by melting and crystallizing chemical raw materials at high temperatures. Many of its properties are superior to natural mica, such as temperature resistance up to 1200°C, good electrical insulation, acid and alkali resistance, transparency, peelability and elasticity. It is an important non-metallic insulating material for modern industries and high-tech industries such as motors, electrical appliances, electronics and aviation.
Project overview：
Recently, news came from the customer site that the mica production line built by FIGHTER was officially put into operation.This project is to process synthetic mica with excellent performance and apply it to diaphragm materials for solar photovoltaic panels and lithium batteries.
The entire production line is designed by FIGHTER, using MW micro-powder mill, fully combined with the user’s site conditions, reasonable process design, compact layout, low-carbon and environmentally friendly production, and high operating efficiency.
Processing materials: synthetic mica
End product use: solar photovoltaic panels, lithium battery separator materials
Equipment used: MW micro powder mill
Technical advantages:
1. High efficiency, low energy consumption and low investment cost
The output of MW micro-powder mill is more than double that of airflow mill, while the energy consumption is 30% lower. At the same fineness, the cost is low and the recovery cycle is short.
2. Low loss of wearing parts
The roller ring is made of special materials and forged with a forging process, which increases its durability several times.
3. Safe and reliable operation in the grinding chamber
There are no rolling bearings or screws in the grinding chamber, and it has been balanced to avoid the problem of screws being easily loosened and damaging the machine, and the operation is smooth and vibration-free.
4. Transmission is more stable
It adopts reducer transmission device, which is more stable and efficient than traditional belt transmission.
5. High powder selection efficiency and precise particle size controlIt adopts a high-efficiency vertical turbine powder separator, which has high efficiency, precise cutting particle size, and no coarse powder leakage. It has variable frequency control and convenient and quick adjustment control. The fineness of the finished product can reach D97≤5μm.
6. Intelligent and environmentally friendly
Automatic feedback and intelligent control directly save labor costs; it uses a high-efficiency pulse powder collector to achieve high dust collection efficiency and no dust spillage; the system is equipped with a soundproof room and silencer to effectively control the spread of equipment noise and meet the latest national environmental protection standards.
