Case Study: Reliable Running Screener

 by General Kinematics,

Screener 1

Challenge

Fall River Foundry, a modern independent non-ferrous foundry, brass die caster and manufacturing company, required a method to reclaim small metallic pieces from their leftover sand, as well as a simple device to process and recover sand from floor sweepings or other refuse boxes.

 

Approach

General Kinematics proposed a Vibratory Two-Mass Screener provides the necessary force and conveying action to break down sand lumps and separate fines.

 

Solution

Screener 2

A single motor, twin mass drive is used to create vibration on the screening deck.  The drive is designed with a specific drive angle to provide screening action within the trough, as well as forward conveyance to move products through the unit.  Internal lump-breaker devices increase residence time for larger sand lumps, allowing them to disintegrate.

 

Results

The Screener has been in service for many years with good reliability, and low maintenance.  Isolation springs to the base supports prevent vibration transmission into the plant floor.  Fines and overs products are easily conveyed into individual fork truck boxes for transfer to reclaim areas. By utilizing this screen, the sand returned to the sand system is cleaner, less scrap and waste material is landfilled, and metallics are recovered for reuse.
