Densifying Clay
Excess air in the voids of fine powders can be difficult to extract quickly, and easily replaced if then handled in an agitated condition. Ajax equipment utilise an internally vibrated, resonant grid system to accelerate de-aeration and then address the feed arrangement to minimise re-entrainment. Each installation has to be considered individually, to take account of existing plant and the degree of freedom to make advantageous changes. Improvements can be secured by converting flow regimes, employing correctly designed feeders and other techniques, but some expertise is required for the best results. ■
Re: Powder Densification
I think that you are looking for a densification system for the material when it is actually inside the bag aren't you?
If so there are a number of manufacturers of bagging machines which have add ons which can help this process, they may slow down your machine capacity though.
I would suggest contacting the manufacturer of your machine or he doesn't have anything, an alternative supplier to see what is available for your type of machine.
Capacity, valve sacks or open mouth, machine type, etc will influence what is practical. ■
Powder densification
We are the largest producer of processed china clay (Kaolin) in India.
One of our product is a powder, having bulk density less than 0.3 and as a result we find it difficult to pack and stuff.
Material after packing if allowed to stay for a day will become 75% by volume and an empty space is formed inside the bag.
We are looking for a suitable densifying system.
Our silos are medium capacity having 25-30 MT with bin actuator.
It is also understood that passing air through the material can densify but on clay we dont lnow.
Can someone throw some light.
