Low Ash Rubber Lined Steel Grinding Jar, 2 Size, 2.3 Gal/8.7 L

US Stoneware J6122CWR, Low Ash Rubber Lined Carbon Steel Grinding Jar w/ Cover, 2 Size, 2.3 Gal/8.7 L

Lined Carbon Steel grinding jars have "quick change" snap in liners which are especially useful when cross contamination of varied materials must be avoided. The standard liner is neoprene, but polyurethane, low ash rubber, EPDM or Nitrile (BUNA-N) is also available.

All grinding jars are equipped with a positive lid locking bar for quick, easy operation. All units come with precision fit covers having a neoprene gasket. Optional gaskets of other materials are available. All jar sizes (except 000) accept an optional discharge cover which has a grate allowing the grinding media to be retained when the ground material is poured from the jar.

US Stoneware J6122CWR, Low Ash Rubber Lined Carbon Steel Grinding Jar w/ Cover, 2 Size, 2.3 Gal/8.7 L Features:

• All sizes have quick-change snap-in liners This feature is especially significant when varied materials are milled and cross contamination must be avoided

• Using a separate liner for each material protects the product, saves clean-up time, reduces number of jars required.
• Note: Cover liners are not snap-in; a different cover is needed for use with each liner
• Jars are carbon steel
• Recommended where silica contamination must be held to an absolute minimum
• Buna-N, EPDM , Low-Ash rubber, Neoprene, and Polyurethane liners are available

Bench or floor model Jar Mills have one to six jar capacities. Rollers have simple adjustment to use jars from 2—9in (51—229mm) diameter. Mills are used for wet or dry grinding, mixing, and blending of ores, chemicals, ceramics, glass, etc. Special 2in (50.8mm) diameter neoprene rollers keep jars centered during operation. Adjustable speed settings from 0—300rpm. Welded steel frames, roller chain drives, and sealed ball bearings assure long service life. Mills operate on 115V, 50/60Hz electrical supply. Grinding jars and media are ordered separately.

Grinding Jars are Roalox porcelain or premium High Alumina ceramic. Roalox has four times the wear life of ordinary porcelain. High Alumina fired ceramic has higher service life, negligible silica contamination, and polyurethane coated body to minimize breakage. Both have wide mouths for fast loading/ cleaning and neoprene gasketed lids with positive-locking bar and hand wheel. Jar capacities range from 0.3—5.6L, and diameters from 3.4—9.5in (86—241mm). Specimen capacity is approximately 25% of total jar volume. G rinding media required is approximately 50% of jar volume. Largest Jars have Est. Ship Wt.: 28lb (13kg).

Grinding Media is cylindrical with length equal to diameter for maximum surface area. Ultra high fired Burundum alumina with 3.42 specific gravity is ideal for most milling. Burundum is supplied in 10lb (5kg) packages. Premium high-density 5.55 specific gravity Zirconia mills twice as fast as alumina with less wear of grinding jars and media. Zirconia is sold in 5lb (2kg) packages.
