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

HA-2000 has many functions and features, and its advantages are mainly reflected in the following aspects:
1) Touch screen operation, the design structure of the equipment adopts full closed-loop automatic control structure, the gas is all controlled by pressure sensors imported from the United States and pressure regulating valves imported from Japan, the pressure can be monitored in real time and automatically reach the set value of the process.
2) The fuel is propane and the combustion-supporting agent is air, which is the safest combustion mode among the gas models in the market at present;
3) The structure of the spray gun is designed according to the principle of the rocket generator. The flame flow speed reaches over 2000m/s, with large output power and stepless adjustment;
4) The spray gun adopts axial center powder feeding. This new injection method makes the powder dissolve well and distribute evenly in the whole flame, which improves the coverage efficiency and coating quality;
5) It has the function of process recipe storage and invocation. Parameters can be added, modified and saved.
6) The system fuel adopts full closed-loop design, modular design, high-performance PLC control, safe and simple operation;
7) The coating produced has excellent performance with low porosity less than 1% (average porosity less than 0.5%) and high spray efficiency (up to 30KG powder per hour).

Dryer is an important part of a paper-making machinery and equipment, drying internal needs through 120 ºC steam, direct contact with the outside surface corrosive medium in the pulp can lead to serious corrosion on the surface of the cylinder, and the surface of the cylinder is in contact with the scraper, prone to wear and tear problems, drying cylinder surface corrosion and wear, will directly cause quality problems such as paper, fracture, not smooth.
Using supersonic arc spraying to spray metal coating on its surface, the coating formed under thermal spraying has many significant advantages: the bonding strength of coating and substrate is relatively high; Significant corrosion and wear resistance; High energy efficiency, low spraying cost; The cost of the equipment is relatively low, easy to use and maintain, and convenient for on-site construction.
For better surface quality, a supersonic flame sprayed tungsten carbide coating can be used, which will last longer than arc sprayed.
Because the diameter of the drying cylinder is large and the weight is large, the maintenance and transportation of the drying cylinder are very inconvenient. Our company not only has the mature drying cylinder spraying experience, but also can realize in the customer use site, without leaving home, online spraying and grinding polishing.
