Finishing Mill Unloaders

September 13, 2013

Eriez Finishing Mill Unloaders quickly and automatically remove ferrous parts from finishing mill media, helping to improve productivity and efficiency in busy parts finishing operations. Three models are available to match customers' specific application requirements.

All Eriez Finishing Mill Unloaders use a permanent magnet pickup, can be quickly and easily wheeled into position beside the mill and are hydraulically lowered into place. As parts near the surface of the media, they are pulled out by the magnetic field, conveyed up and away from the mill, and pass through a demagnetizing unit before reaching the discharge chute.

The Model 58 C/P Mill Unloader is a fully-enclosed magnetic conveyor with permanent magnets mounted on an endless chain revolving beneath a stainless-steel plate. This unit is designed for lightweight parts.

The Model 9B-P Mill Unloader utilizes a cleated conveyor belt with a 12-inch diameter magnetic head pulley to pull out parts. Magnetic rails above the pulley hold parts firmly to the belt until they reach the horizontal portion of the conveyor.

The most versatile Eriez Finishing Mill Unloader is the Model 9B-DP. This unit can normally remove all parts from a 10-20 cubic foot mill in five minutes or less. As parts are pulled out of the media and carried to the top of a 12-inch diameter magnetic drum, they jump across an adjustable gap to an eight-inch diameter head pulley revolving with a horizontal conveyor belt. Any trapped media falls back into the mill as the parts move through the demagnetizer to discharge.

    milling machine ( mill)

    Runs endmills and arbor-mounted milling cutters. Features include a head with a spindle that drives the cutters; a column, knee and table that provide motion in the three Cartesian axes; and a base that supports the components and houses the cutting-fluid pump and reservoir. The work is mounted on the table and fed into the rotating cutter or endmill to accomplish the milling steps; vertical milling machines also feed endmills into the work by means of a spindle-mounted quill. Models range from small manual machines to big bed-type and duplex mills. All take one of three basic forms: vertical, horizontal or convertible horizontal/vertical. Vertical machines may be knee-type (the table is mounted on a knee that can be elevated) or bed-type (the table is securely supported and only moves horizontally). In general, horizontal machines are bigger and more powerful, while vertical machines are lighter but more versatile and easier to set up and operate.
