Inclined Vibrating Screens and Scalpers
 HRI inclined vibrating screens have become the world standard in bulk materials processing, proving their exceptional reliability and high productivity in the toughest industrial environments.At the heart of every screen is the unique V-Line vibrator, designed for long life and low maintenance.
  At the heart of every screen is the unique V-Line vibrator, designed for long life and low maintenance. A choice of oil splash or grease lubrication to suit specific operational requirements ensures maximum bearing life. Easy of servicing means that bearing changes or counterweight adjustments can be made in minimum time, keeping HRI screens working productively. For medium and heavy duty applications the standard HRI range includes single, double and triple deck configurations in sizes from 1000 mm wide x 2400 mm long up to 2500 mm wide x 7200 mm long, all with single V-Line vibrator assemblies. Custom built options include quad decks, double or triple vibrator assembly and VX or VXX extra heavy duty perforated plate and grizzly bar scalpers.

QUAD-V WIDE SCREENS are designed for use on screens up to 4.000 mm, HRI Quad-V is specifically for use on high volume application. Screen formats can be single, double or tripple deck or, for special applications, multi-slope ´banana´ decks. Lenghts range from 6.000 to 10.800 mm. The unique Quad-V vibrators are mounted above or through the side plates, coupled across the width of the screen using cardan shafts and transmitting vibratory forces directly into the screen frame. This makes for significant cost and weight savings.

Fully floating machine with models for either inclined or horizontal installations.

  Each vibrator has two double row, spherical roller bearings with bore sizes up to 160 mm. Drive to the vibrator can be either through cardan shaft or using V-belts which enables live mounting of the motors on top of the machine, making a completely self contained installation.

  Inclined screens use a single or double pair of vibrators mounted through the centre of gravity of the machine to impart a circular motion. A modified circular motion can be achieved when the vibrators are mounted on top of the screen. For low angle and horizontal installations two pairs of vibrator mechanisms are run in contra-rotating directions to impart an elliptical motion.

Double shaft extensions
  Standard shafts proved drive to the vibrator from one side only. An optional double shaft extension enables the hand of drive to be changed to the other side of the screen quickly and easily.
