Component	Characteristic	Parameter
E-2000 Powder feeder	1. The powder feeder is a high-precision powder feeding mechanism based on the principle of toothed dial with vibration structure and gravity falling, with uniform powder output and wide particle size range. 2. After the top cover is sealed, the powder condition in the powder cylinder can be clearly seen through the visual transparent observation window on the powder cylinder. 3. Nitrogen or argon with small flow is used as powder gas. The powder is rotated to the powder outlet along with the powder tray at the bottom and enters into the spray gun together with the powder gas. 4. Adopting the latest international turnover structure, it is convenient to clean the powder, which can be discharged from the lower mouth, or can be poured from the barrel body.	1. Powder feeding: toothed dial 2. Cleaning method: barrel body flip 3. Volume of powder storage tube :2L 4. Powder feed gas: nitrogen 5. Powder feeding air pressure: 0.15-1.2mpa 6. Powder feeding speed :0~500g/min 7. Powder feeding accuracy :±1% 8. Powder size :1~150 m

High wear resistance: the roller is subjected to abrasive wear, adhesion wear, fretting wear in the process of work, the wear resistance is not enough, not only affect the precision of the roller surface and the quality of the pole piece, but also reduce the production efficiency;
High density: dense structure, low porosity, high corrosion resistance, also conducive to prevent pole coating and other foreign matter into the roller surface;
High precision: the straightness, ellipticity and coaxiality of the roller are required to be high, otherwise it will cause uneven thickness of the battery electrode and poor binding force.
The company uses HVOF thermal spraying technology to prepare multi-component cermet composite coating on the surface of high precision roller of lithium battery, which has the following characteristics:
1, High coating hardness, microhardness up to 1100-1400HV0.3, with very high wear resistance;
2. The coating structure is uniform and dense, with low porosity, (<0.6%), and does not stick to materials, and does not react with battery electrode material;
3, the coating bonding strength is high, using FM1000 adhesive test, can reach more than 90MPa.
4. Subsequent grinding by high precision CNC grinder to ensure the straightness, ellipticity and coaxiality of high precision roller, which is less than 0.002mm
