Dryers

The Maguire LPD:
A revolution in resin drying.

The Maguire Low Pressure Dryer (LPD) is a revolutionary device that uses vacuum to accelerate the resin drying process. The use of vacuum provides many process and cost benefits compared to conventional drying technology.

Maguire Products did not invent the science of low pressure (vacuum) drying. In fact vacuum drying has been used in the manufacturing process of plastic resins, chemicals, food and pharmaceuticals for many years. But, Maguire Products is the first to bring this technology to the plastics industry in a package that is affordable, reliable and simple to operate.

Why is the LPD Better?

Speed of Drying

Typically the vacuum dryer will dry materials in one-sixth the time of a desiccant dryer. If your desiccant dryer drying time is 4 hours, the vacuum dryer will do the job in 40 minutes. The result is time-savings of 3 hours and 20 minutes every time you start up a dryer. This not only represents reduced energy cost (see below), but could also represent 3 hours and 20 minutes of additional production time.

Energy Savings

Side-by-side testing of the vacuum dryer and a desiccant dryer shows reduced energy consumption of 70 - 80%. The key to the reduced energy consumption is that the vacuum dryer does not rely on desiccant. Desiccant, once saturated, must be regenerated by a heating and cooling process so it will again be able to absorb moisture. All energy required to regenerate desiccant is lost to ambient.

Reduced Maintenance

Since desiccant degrades over time it must be replaced on a regular basis. This expense is avoided with a vacuum dryer. In addition the need to monitor the condition of desiccant is eliminated.

Low Material Stress

Long drying times at elevated temperatures can cause thermal, chemical and physical material degradation. Materials if exposed to prolonged elevated temperature during drying run the risk of degradation including discoloration and/or IV drop which leads to reduced physical properties of the end product. The reduced drying time required with the vacuum dryer dramatically reduces the risk of material degradation. Since the vacuum dryer first heats up the material, then applies vacuum to accomplish drying the heating cycle is only 20 to 30 minutes.

On-The-Fly Material Change

Additional savings can be achieved with the vacuum dryer in the form of on-the-fly material changes. Since the vacuum dryer dries in batches a material or color change can be accomplished on-the-fly. This means no downtime related to clean-out of the drying hopper during a material change. Every time you have a material change with a desiccant dryer the dryer must be shutdown and the drying hopper cleaned. This is normally a time-consuming, labor-intensive process. The vacuum dryer will automatically notify the operator when it's time to conduct an on-the-fly material change. No interruption of the drying process occurs during the on-the-fly material change.

Loaders

Clear-Vu™ Loading System

The Clear-Vu™ Loading System from Maguire Products provides the benefits of a central system with the added convenience of portability and low maintenance. This complete vacuum conveying system provides automatic loading of up to 3,000 lb/hr (1,350 kg/hr). The Clear-Vu controller provides the backbone of a flexible loading system that will control up to 8 stations.

MLS System Controller

The Clear-Vu microprocessor controller is a compact, remotable unit with the capability of loading up to 8 receivers. Exclusive "Autofill" circuitry automates the setting of fill times.

Easy Setting of Fill Time
As the receiver is filling, the operator uses a push-button to activate the "Autofill" software. When the desired level has been reached, the button is released and the fill time for that station is set.

Automated Loading
Once load times have been set for each receiver, the controller sequences through the various stations loading each as that station's level sensor calls for material.

Individual Station Alarms
Load-failure alarm with reset is incorporated in the controller and may be selectively activated for any or all stations.

Venturi Loading Systems

Maguire Venturi Loaders keep your hopper filled automatically and are available with both visual and audible alarms to warn if the loader fails to fill the hopper. If floor personnel fail to respond to the alarms within 5 minutes, a process shutdown feature (available as an option) will shut off the flow of natural material to the process (preventing production of off-color parts). The control can accommodate up to 4 switches to control 4 venturi loaders.

Feeders

How Maguire Feeders Work

The controller signal cord is plugged into an outlet that is energized only when the process machine screw runs. During each screw return cycle (or continuous for extrusion), the motor runs and color is metered into the throat of the process machine.

The digital counter located on the face of the controller provides the means for predetermining the exact degree of auger rotation and, therefore, the precise amount of color that will be added. For injection molders, the motor will shut off when the preset count is reached during each cycle. For extruders, an optional digital tachometer feedback is available to ensure that motor speed is precisely regulated regardless of changing torque requirements or variations in plant voltage.

To determine the proper setting for the counter, a simple formula is used based on percentage of color required, a predetermined metering rate, and total shot weight in grams (or pounds per hour for extrusion applications).

The controller contains a 1/27 HP DC Permanent Magnet motor with variable speed control. In the standard configuration, the motor is close coupled to a heavy duty gearbox. As the motor turns, a "hall effect" pickup device on the motor sends 3 pulses per revolution to the microprocessor controlling it. The gearbox ratio of 53:1 means that 159 pulses (3x53) are received for every single revolution of the motor output shaft.

The thumbwheel switch on the controller should be set to the exact number of pulses that the motor is going to run before stopping. The microprocessor in the controller automatically multiplies the setting by a factor of 10. A setting of 16 on the controller will allow the controller to receive 160 pulses or run approximately 1 revolution before stopping (regardless of motor speed).

• Series MCF
• Series MLG
• Series MPF

Pumps

MPA Peristaltic Pumps

The patented Maguire peristaltic pumps are designed to accurately meter precise amounts of liquid color into the main flow of natural material directly above the throat of your process machine. Metering is accomplished by the compression and release of a flexible pumping tube by six hardened dowel pins that rotate within a Celcon. housing.

MDA Drum Pumps

Self-priming Positive Displacement
The Progressive Cavity Drum Pump meters liquid color by positive displacement. The pump consists of a single helix steel screw, called a rotor, rotating within a double helix hollow stator constructed of an elastomeric material.

The rotation of the rotor within the fixed stator causes empty pockets or voids to travel or progress upward, drawing liquid into one end and expelling it out the other end, producing a positive displacement pumping action. The double helix stator produces an overlapping of voids resulting in smooth non-pulsating pumping action. Pressures of 200 to 300 PSI are achievable.

Fits on 30 or 55 gallon drum
The pumping unit is mounted at the end of a stainless steel pipe which serve3s a double purpose. First, it positions the pumping unit at the bottom of the liquid drum totally immersed in the liquid while the controls and drive motor are positioned safely above the drum. Second, the pipe serves as a conduit in which the liquid flows up and out of the drum. A quick-release coupling joins the motor and shaft allowing for easy removal of the motor and controls from the pumping unit.

Automatic Speed Control
Because pumping rate is directly related to pump operation, accuracy is obtained by controlling the exact degree of rotation of the drive motor. The unique Maguire Digital Controller is designed to do this with precision.

A digital counter provides the means for predetermining the exact degree of rotation and, therefore, the precise amount of coloring that will occur during each cycle. When the preset count is reached, the motor automatically shuts off, ensuring that no excess colorant is metered.

Motor speed is automatically controlled by the internal microprocessor to allow color metering to occur uniformly over the entire screw return cycle. The operator need not concern himself with motor speed adjustment, voltage fluctuations or changing cycle times.

To determine the proper setting for the counter, a simple formula is used based on shot weight in grams, percent let-down desired and the liquid color weight in lb/gal or gm/l. Once production is started, the counter setting can be adjusted up or down as required to achieve the desired shade of coloring.

In addition to this precise control of the quantity of liquid being metered, the microprocessor ensures the motor speed is precisely held regardless of changing torque requirements.

Extrusion Following
With this option the drum pump follows the speed of the extruder automatically. Any changes in extruder speed are followed exactly by the pump output.

A tachometer that currently exists on your extruder provides either an AC or DC voltage output. When the "tachometer feedback" signal is fed into the Maguire Drum Pump controller, the pump output is then able to match the extruder speed up or down.

MPM Pre-Mixers

Series MPM Pre-Mixers automatically and continuously provide thorough mixing of resin, regrind and additives as they enter the throat of the process machine. These mixers are designed to mount directly to the feed throat of the process machine with hopper and hopper loader mounted directly above. When adding liquid color, color concentrate or other additives, the Maguire Pre-Mixer ensures a homogenous blend, and coloring is more efficient, more thorough and more uniform. Color consistency of the finished product is improved, and problems such as streaking are virtually eliminated.

Visible Color Flow. No Clogging.
Color or additive is introduced into an air pocket just above the mixing blades. Material dispense is visible through the clear window. The non-clogging design provides consistent flow of blended material.

Easy Cleaning
The wrap-around mix chamber insert is easily removed, allowing clear access to all material contact surfaces. Stainless steel internal parts facilitate cleaning and will not corrode or discolor.

Baffle Plate Prevents Packing and Improves Mixing
As Material flows into the Pre-Mixer chamber, it must first cascade over a sloped baffle plate. This prevents packing and eliminates downward pressure on the process screw. The drive motor runs cooler, higher mixing speeds can be used, and overall mixing is improved.

Safety Interlock (Models MPM-50 & MPM-18)
The clear hinged door is equipped with an electrical interlock for operator safety.

Reduce Color Consumption
In many cases thorough mixing will actually reduce the amount of color required to produce the depth of desired coloring.

The Maguire Radial™ Granulator features a patent rotary cutting method which delivers superior performance at a lower price that conventional granulators. The unique rotary cutting action eliminates flyback and requires less torque for granulation. The standard unit delivers 6 cuts per revolution or 10,500 cuts per minute with a 1,750 rpm motor. Two feed throat openings are available: 6" x 7.5" (R9) and 12.5" x 12.5" (R18). The Radial Granulator is safely and easily disassembled for quick material change. The front access door is fully interlocked and easily opened to enable unlimited access to material contact surfaces.

Shuttle™ Granulators

The Maguire Shuttle™ Granulator is a low cost alternative to conventional size-reduction of any large parts or purgings. This completely new type of plastics granulator automatically transforms large reject parts, purgings and other bulky or difficult-to-handle scrap into high-quality regrind but costs substantially less than conventional equipment.

Until now, size-reducing large parts has meant buying a massive heavy-duty granulator, using a shredder in combination with a standard granulator, or cutting the parts with a saw before granulation.

The Shuttle Granulator is a two-stage system that in the first stage literally planes reject parts into small pieces. In this "planing" stage the scrap or reject part is automatically shuttled back and forth over a table surface that is split into two levels like a carpenter's plane. Mounted in between the two levels is a staggered knife rotor that turns at 1750 rpm. The rotor reduces the scrap into small pieces and propels them into the hopper of a Radial Granulator. This Radial Granulator is positioned directly below the planer and performs the final size reduction of the product.

Heavy Duty Granulators

Maguire manufactures heavy duty granulators for high throughput and long life. Maguire granulators provide uncommon productivity, more uptime, and greater versatility than other large machines on the market.

Besides being rugged, Maguire granulators are more user-friendly that conventional units and provide easy, safe access to the cutting chamber for cleaning or changing knives. With minimal disassembly the rotor can be removed on-site for repair or replacement making it unnecessary to return the unit to the manufacturer for rotor removal. This versatile design allows the user to change applications while utilizing the same cutting chamber.

Drive motors range from 100 to 250 HP for applications such as:

• Heavy purgings
• High volume materials like post-consumer waste or film
• Tough or abrasive products like electrical cable
• Large moldings like automotive body panels and blow molded containers.

A proprietary QuaDischarge™ base provides diverse material discharge options including discharge to pneumatic conveying systems, drums, gaylords, or mechanical conveyors.
