Size Reduction Q&A
-
I need to jet mill chemicals with high freezing points (say 200°F and above) from 55 gal drums, where the product freezes such that it forms a 55 gal block. As the materials are generally somewhat brittle (will breakup without extreme energy input), what equipment exists to initially breakup such a large block while in the drum?Answered November 23rd, 2009 by Expert:Thank you very much for your processing question. It is common for materials to agglomerate or fuse together over time from exposure to heat, moisture, or compaction forces. Some customers will request that we use a flow agent or partitioning agent to prevent material from forming agglomerates after milling. These agents can be co-milled with the feed stock or blended in after milling.
Your dilemma requires a device that will accommodate the 55 gal block and bring it down to a particle size that can be fed into your jet mill. We did some web surfing looking for coarse crushers and shredders. We found Komar Industries (www.komarindustries.com). They have a lot of shredder options. We liked the “Tiger Electro Shear”
(www.komarindustries.com/files/tiger-electro.pdf). We do not have any working knowledge or pricing on this equipment, but it appears it may be a viable option for you.
