Lf Pumping - Ultimate Dryer Of A Growing Range Of Materials
You could could use air to dry rather than heat. We a lot of experience drying trona, & chalk for a vast array of market sectors.
The LamiFlo System
The key Points associated with this unique environmental system, compared to any known rotary, ventura, vibrating fluid bed, or static fluid bed drying systems for materials are:-
•Guaranteed energy savings, as there is no requirement for any gas, gas/oil or diesel fuels, to generate heat source to dry materials.
•Reduced carbon footprint.
•Operational advantages throughout the transportation, drying, and delivery process.
•Compact size.
•Guaranteed Low maintenance costs.
•Minimal disruption of integrating system in to current process line.
•Liquids, sludges, and aggregates up to 75mm.
•Bespoke systems can dry sand from 60% moisture content down to 0.3%.
•Bespoke systems can handle up to 500 tonnes per hour.
What materials can be dry, pump, or material handle? http://lfpumping.com/material-handling.php
We are confident that this system offers to you the very latest cutting edge technology, packed with financial and delivery savings. We look forward to discussing all your transporting, drying, crushing, and grading applications. ■
Surface Finish and Powder Drying Rate?
Anyone have experience with trading off dryer wall smoothness for heat transfer to paste/powder systems?
I have a paste that drys into a free flowing powder, if low enough in moisture. Too much moisture and the organic salt tends to coheasive/ adheasive. At higher temperature differentials and rates, the agitated LIST Discotherm dryer loses some heat transfer.
The fouling is periodic. Lowering the inventory restores the lost heat treansfer. That the fouling clears so easily makes me think that a packed solids layer forms against the cylindrical wall. Lowering the inventory allows material to be dislodged by the impeller and gravity.
So, to reduce adheasion/friction/surface energy of the wall, I was thinking of adding a diamond like coating. It's low friction, and has high thermal conductivity.
What are the heat transfer ramifications of doing this? Should heat transfer should go up because of less "fouling" rather than down because of a coating? ■
