Size-Reduction System turns reclaimed purgings into regrind.
October 9, 2009 -
Purging Recovery System(TM) enables purgings - rock-like lumps of plastic that are byproducts of job and color changes - to be reclaimed as valuable raw material. Dual-stage system slices or planes hard lumps of plastic into small pieces and then reduces pieces to uniform, high-quality regrind. Shock-resistant in operation, system features heavy-duty construction with machine base and sound enclosure that minimize noise. Design also facilitates access for loading
Maguire Introduces First Size-Reduction System for Routine Reclamation of Purgings as Valuable Regrind
Waste-Ending Purging Recovery System(TM) Eliminates Disposal Problems and Can Pay for Itself in as Little as a Year's Time
ASTON, PENNSYLVANIA, U.S.A., October 5, 2009: Plastics processors need no longer face the perennial question of what to do with purgings, those rock-like lumps of plastic that are byproducts of job and color changes. Instead of wasting purgings by sending them to landfills, processors now can use innovative equipment from Maguire Products, Inc. to reclaim them as raw material whose value may well repay the equipment investment in a year's time or less, according to B. Patrick (Pat) Smith, vice president of marketing and sales.
The MaguireŽ Purging Recovery System(TM) is a two-stage system that first slices or planes hard lumps of plastic into small pieces, then reduces the pieces to uniform, high-quality regrind. Maguire sells the entire system, including the second-stage compact granulator, for only US$28,000. Since purgings typically range in size from 1 to 10 lb. (0.45 to 4.5 kg) and may be generated at a rate of several to dozens per shift in a custom molding operation, a processor using resin that costs $1.00 / lb. could reclaim hundreds of dollars worth of raw material per week.
"The Purging Recovery System is the only equipment designed specifically for the rugged work of size-reducing hard, heavy masses of plastic," said Smith. "We developed this system to be heavy-duty in construction, shock-resistant in operation, and easy for operators to access for loading. A specially constructed machine base and sound enclosure keeps noise at a minimum."
Maguire is offering the Purging Recovery System throughout the Americas. A streaming video demonstrating the features of the system and its mode of operation is posted on the company home page at www.maguire.com.
How the MaguireŽ Purging Recovery System(TM) Turns Waste into Regrind
A purging consists of the transitional material that passes through an extruder as the operator shifts from one job or color to another. Typically the polymer is discharged onto the shop floor, hardens, is scraped up, and is disposed of.
"Since a five- or ten-pound lump of hard plastic could damage the rotor in a $200,000 heavy-duty granulator, until now there have been limited options for reclaiming this material," said Smith, "yet over time purgings add up to a waste of material valued at thousands of dollars per year."
The Purging Recovery System draws on the simple concept of the carpenter's plane. It consists of a table that is split into two levels and a purging containment chamber that, upon startup of the system, moves back and forth over the table surface. Mounted at the point of disjunction between the two surface levels is a rotor with staggered knives that turns at 1750 r.p.m., reducing the purging to small pieces and propelling them at high speed into the hopper of a compact granulator beneath the table. As material is planed away from the purging, a pneumatically-driven hold-down plate in the containment chamber keeps the purging in contact with the knives.
The base and surface of the table and the walls of the containment chamber are built of thick steel panels with reinforced weldments at impact- or load-bearing points. The traversing of the containment chamber is driven by a pneumatic/hydraulic system that is resistant to compression caused by shocks as the purging encounters the rotor knives. The containment chamber is low enough to provide easy loading of the bulky purgings, and the hold-down plate is designed to permit easy access to the chamber. The granulator beneath the table is designed to be easily accessed for cleanout.
