overflow method, Advance and retreat supplies method
based on discharge control, certain amount of filler is kept in the mixer tank during the continuous mixing process, and this certain amount of filler is mixed with new filler, alternating and superimposing activity make this part of the material maintain the condition of discharge, material coming out with overflowing.
Advance and retreat supplies method:
based on the mixing agitator, agitator can achieve force of synchronous or alternating of feeding and retreat. Three methods: more feeding less retreat, less feeding more retreat, equal between feeding and retreat can be chosen based on the mixing process and nature of the materials.
Working conditions of the continuous mixer
1. The material should be supplied steadily and continuously by the feeding system
2. The feeding speed of different materials should be subject to the formula proportion
3. The materlals after mixing should be timely and efficiently processed by the next equipment, any block is forbidden
4. Little additives like below 5% content proportion should be mixed with bulk material beforehand.
5. The feeding speed decides the output of continuous mixer, the output, uniformity and properties of material decide the type and size of mixer.
1. Continuous mixer has single shaft and two shafts structure according to different material and different output.
2. the paddle blades can change into removable ones, which decrease the replacement costs after the blades worn out.
3. To realize the technical of drying, cooling and keeping warm, the mixer can be added a jacket structure out of the tank. Hot water or steam or industrial oil can circulate in the jacket. Liquid filling system can be installed at the top cover. The different material of the atomized spray nozzle can realize the injecting of acid or alkali liquid.
4. The tank and the agitator can be coated with other material like PE, PTFE, carbide, etc. to realize the resistance of wear-out, acid/alkali, or explosion
Powder dome valve originated from Shanghai ShengLi for powder mixing equipment in its feeding, discharging system and process technology, combined with more than ten years of use and verification, it can close the material flow effectively, quickly, reliably and long lifetime. it provides as a unique product to the powder production industry users.
The core of the dome valve is a cambered surface. The sealing ring is close to the specially designed core. When the valve is in the open position, the material passes through from the arc surface and the sealing ring of the sphere chamber, which not only reduces the friction and extrusion between the valve core and the material, but also does not cause the blockage and obstruction of the material. The sealing ring fixed on the valve body can also remove the material adhered to the arc surface and ensure the reliability of the valve seal.
The advantages of the dome valve are:
1. Compact structure and light weight.
2. No seal stuck or pressed when open.
3. Powder material will not crush and break when closed.
4, The inner space of the dome valve is large, and the material flow is not hindered.
5. Vacuum can be produced in the production process, and the vacuum level can reach 0.8MPa
6. Good applicability of oily materials and viscous materials.
7. The clamp type of dome valve can be cleaned frequently in the production process.
8. Bigger than DN250 valve can be installed with observation glass.
9. Easy to load and unload
10. Pressure sustainable: 0.2MPa.
11.Temperature range: -20 ℃ +200 ℃.
12. Surface treatment meets GMP requirements.
13. long service life.
14. Drive selection: manual, pneumatic, electric.
15. sealing materials: silicone rubber and fluorine rubber
Applicable special materials:
1. materials will be fermented,or corrosive.
2. the material is damp and will lump and harden.
3. materials are adhesive.
4. material will react and creat exhaust air.
