What kind of valve is suitable for feeding granular silicon, as metering is required. It can control the amount of material fed.
Thread Content
The materials are fed downward from above and below the horizontal plane, so gravity is the main force driving the feeding process. But it will release flammable gases. Therefore, the valve must be airtight. The particles sometimes clump together. It has a relatively high hardness. Therefore, the valve should not get stuck frequently, and its inner diameter should not be too small, as this could lead to blockages due to the formation of deposits. Material feeding pipeline DN80--DN150. Which valves meet the requirements, or what type of valves are suitable?
This can be discussed with valve manufacturers; there should be such valves available
Airtightness prevents external leakage. No requirements for internal leakage. For measurement, the material discharge rate per minute should not be too high nor too low. There are floor scales to help with measurement. Therefore, pneumatic or electric valves are mainly used to prevent the material from flowing downward. And it will not get stuck by clogged valves when switched on and off.
I’m not sure what to say; I’ve only been working for a short time. I want to submit a suggestion for improvement. The angle valve being used now gets clogged very easily. It gets taken apart often. There’s no need to worry about the rotating discharge valve getting stuck and not moving.
Only gate valves can be used as a makeshift solution~~~
I suggest trying a disc valve; once it is opened, it functions like a pipe, with no flow resistance or reduction in diameter, so there’s no need to worry about blockages. All the internal components are made of tungsten carbide, which is wear-resistant, so there is no need to worry about wear issues. The most important aspect is the use of a switching mode that combines revolution and rotation; it not only offers self-grinding and self-adjustment functions, but also features the ability to clean the materials and prevent their accumulation.
The lift-type isolation ball valves produced by our company can meet your usage requirements
I’m not too sure about the others, but near the silos, gate valves are generally used more often.
Would a full-bore ceramic ball valve or a star-type feeding valve work? Also, what is the approximate temperature at which the silicon powder is fed?
