The Preiser Model 500 Tumbler is designed and manufactured to comply with ASTM D-3402 Standard Test Method for Tumbler Test for Coke, and ASTM E-279 Standard Test Method for Determination of Abrasion Resistance of Iron Ore Pellets and Sinter by the Tumbler Test.

The drum is made of ¼” thick A-36 steel plate with welded seams.  It is 36” ID, 41-½” long and has two pieces of stainless steel angle iron inside, as called for in the standard.  The access doors, one on either side of the drum to access the separate chambers, slide in a track to prevent the operator from having to lift the door off the drum.  These access doors will be locked using quick lockdown cams.

The tumbler is controlled with a programmable logic controller (PLC) and a 3” monochrome touch screen and pushbuttons for start, stop, jog and e-stop.  Lock-out/tag-out is accomplished by way of a rotary disconnect and individual motor circuit breakers.
