Laboratory Disc Mills

Hand-Cranked or Motorized Laboratory Disc Mills provide effective performance for limited dry or wet grinding to moderate fineness. Mills are useful for coal, chemicals, ores, pharmaceuticals, nuts, grains, and other friable materials.

Both the Hand-Crank and Motorized Disc Mill process materials between a set of iron alloy fixed and rotating 4in (102mm) diameter grinding discs for reduction. Feed hoppers have 50in³ (0.8L) volume, and final fineness is easily set by thumbscrew adjustment of grinding disc clearance. No. 80—No. 100 (180—150μm) is a typical fineness limit. Mills disassemble quickly without tools for cleaning.

Disc mills are supplied with tooth-type feed augers for dry materials and a set of fine-grinding discs. For wet or oily materials, optional Wet-Feed Auger sets are available and include a worm-type feeder and fine-grinding discs. LCA-171 Coarse Grinding Disc Set fits either mill and allows higher throughput of coarse product. LCA-171 is purchased separately.

• Hand-Crank Disk Mill is a bench-mountable unit that attaches by screw clamp to a surface thickness of up to 1.5in (38.1mm). Throughput varies with material type, but 10lb (4.5kg) per hour is typical.
• Motorized Disc Mill is available in 115V (60Hz) and 230V (50 or 60Hz) capacity. These mills have a 1/3hp single phase Gearmotor mounted on a rigid cast aluminum base, with a plated cast iron body. Throughput varies with the type of material, but 40lb (18kg) per hour is typical.
