The 100 Series Blender features an exceedingly precise Micro-Pulse™ metering device.
The 100 Series Weigh Scale Blender from Maguire Products provides a practical and affordable means for molders and extruders with small processing equipment to blend color or additives with extremely high precision. One of the smallest machines of this type, the unit weighs and blends up to four components at rates up to 450 lbs/hr (204 kg/hr).
The 100 Series Blender features an exceedingly precise Micro-Pulse™ metering device. At the heart of the Micro-Pulse™ system is a unique slide gate apparatus attached to a pneumatic cylinder with a very short (0.125 in.) stroke. The cylinder is rapidly and sequentially pulsed up to 20 times per second during dispensing of the ingredient, permitting very precise total doses. For instance, a dispense can be programmed to produce 25 on/off cycles of the cylinder, each cycle delivering about 0.1 gram of material, for a total dispense of 2.5 grams.
The machine is self-calibrating, never needs adjustment for accuracy, and achieves an overall precision of 0.1% of specified blend. Proprietary microprocessor-control technology monitors and confirms the individual weight of each material component (natural, regrind, color, and additive). Any variation that may have occurred in the actual weights of any components is detected and compensated for. This provides for a continuous process of calibration and correction, assuring extreme accuracy of the blending process. The controller also compensates for use of any previously colored regrind, reducing in accordance the amount of color to be dispensed.
Ideal for processors with frequent material change
The 100R Series Blender includes a two-compartment stationary bin for natural resin and regrind, along with two smaller removable bins. Processors with frequent product or color changes can easily and quickly empty and refill the removable bins. The lightweight bins are equipped with integral shutoffs to eliminate spillage, and hinged lids for easy clean-out. Duplicate standby bins are available which can be pre-loaded and color change time can be reduced to the few seconds it takes to swap bins. Easy access to all material contact surfaces of the machine including hopper, feeder(s), weigh bin, and mixing chamber permits rapid color change without the use of any tools.
All components are blended by weight based on the setting shown on the master controller. Each component is dispensed separately into a single weighing chamber, and then all components are dropped into a continuous mixing chamber which delivers a homogenous blend.
The entire unit is designed to mount over the feed throat of the process machine. Maguire's unique weighing method allows blenders to operate correctly in spite of vibration or shaking caused by the molding machine or extruder.
All Materials Metered By Weight
Accuracy is constantly monitored.
Automatic compensation for varying densities.
In actual operation, color and additive is held to within 1/10 of 1% of requested ratio.
Every batch is followed by an error correction routine that continuously hunts toward perfect dispense weights.
Direct Setting of Percentages; No calculations
Enter settings for percentage of color, additive, and regrind on the thumbwheel switches and the system does the rest.
Very Simple Operation
Load hoppers with material; REGRIND, NATURAL, COLOR, ADDITIVE.
Set thumbwheel switches for percentage desired.
Turn controller on.
The unit now operates automatically, adding components in the proper percentages. If material runs out an alarm will sound.
