UNION PROCESS: Larger Combination Laboratory Mill
Union Process, Inc. has built a combination mill comprised of an S1 batch mill and an SDM-05 mill designed to operate as a bead mill. Much like the company’s HD-01/HDDM-01 combination mill, this laboratory mill is reportedly a larger version of the same principle. The S1/SDM-05 combination lab mill provides the option to run at slower speeds (approximately 100-500 rpm) and uses media ranging from 1/8-3/8 in. for customers who want the versatility of being able to process both fine and coarse material without purchasing two complete mills.
The SDM option runs at higher speeds (300-2,000 rpm) and utilizes grinding media as small as 0.25-2 mm. The SDM option features a side discharge with screen and a shaft with specially designed agitator disks, which are available in tool steel, stainless steel, plastic, or zirconium oxide.
Customers may choose from two drive systems: the electronic variable frequency drive (explosion-proof or non-explosion-proof) or the mechanical variable speed drive (explosion-proof). Either system is reportedly available in a metal-free configuration.
