The Basics of Powder Coating Coverage

ACR = 192 3/1 5 (specific gravity)/2 (mil thickness) x 50 (transfer efficiency) ACR = 32 05 square feet per pound of Powder A Next take your cost per pound and divide it by your ACR Cost per square foot = $5 00 (cost of one pound of powder)/32 05(ACR) = cost is $0 16 per square foot of coverage by Powder A

Ball Mill

The ball mill is a tumbling mill that uses steel balls as the grinding media The length of the cylindrical shell is usually 1–1 5 times the shell diameter (Figure 8 11) The feed can be dry with less than 3% moisture to minimize ball coating or slurry containing 20–40% water by weight
