Tumbler-index-apparatus ref. Standard - is : 6495 - 1994 precision tumbler index test apparatus for iron ore pellets determination of resistance of iron ore pellets to breakage or degradation by impact and abrasion. The precision's, ti01b tumbler tester for iron oxide lump cores, sinters, and pellets consists of a cylindrical drum constructed of mild steel plate. The two circular sides of the drum have two stub axles attached through two circular flanges. The axles are held in two double-row self-aligning ball bearings with the common axis of the axles located in a horizontal plane. The drum is rotated about its axis at the specified speed with the help of an electric motor, worm reduction gearbox, and vbelt pulley arrangement. A pre-set type digital counter is provided to record the number of rotations of the drum and to automatically stop the motor after a set number of rotations. The bearings on which the drum is pivoted are supported on a heavy-duty fabricated metal frame made from mild steel sections. The motor and worm reduction gearbox are also mounted on the same frame to give a single composite unit. A sheet metal hop- per is provided below the drum to collect the material coming out when the drum is rotated with the door removed. The hopper has a square opening to enable the collected material to be removed. A removable stainless steel tray is provided to collect the material from the drum.
