A major component bin of 250 or 500 lbs. capacity is supplies for the Virgin and Regrind Components and smaller 50 or 100 lb. capacity bins are supplied for the additive components. Screw sizes range from 1″ for color and 1-1/2″ to 3″ for major components. 1/2 HP DC Drives are supplied as standard.

The volumetric blender in the picture is supplied with an optional Metal Separators for the removal of ferrous and non-ferrous metals.

The blender is comprised of one (1) large bin, either 150 lbs. or 400 lbs. capacity, with a metal partition in the middle. One side is used for regrind, the other side for virgin. Each side has an outlet which feeds material onto a single wide tray vibratory feeder. An adjustable gate on each outlet is used to establish the ratio of virgin to regrind being fed to the vibrator. The vibrator feeds both materials through a mixing chute directly into the processing machine hopper. A level switch, located in the machine hopper, controls the blender feeder maintaining a full hopper at all times.

An important optional feature available on the Mini-Blender is color concentrate or additive blending. One or two small bins can be mounted on the main bin. These bins use a special low feed rate vibratory feeder and control, feeding the color (or additive) material directly onto the large virgin/regrind vibrator. The ratio of color (or additive) to virgin is then set by adjusting the output of this auxiliary feeder control. Once the basic ratio is established, a master control permits increasing or decreasing the output of the blender without changing the preset ratio.

These include the standard model CFV-2 with Vector drive, the CCF cone in cone feeder and the LPF Low Profile type feeder.

These series of crammer feeders are force feeding devices that are designed to compact fluffy materials at the extruder screw to provide a uniform density and relatively consistent head pressure.

Our crammer feeders employ the use of a Flux Vector drive, a true torque device which enables the system to feed up to a 50% fluff/pellet blend with a consistent material density at the extruder throat. The benefits of this crammer feeder include true cramming action which provides relatively constant head pressure throughout the range of normal extruder needs.

For these reasons, the majority of loss weight feeder stations supplied to the industry utilize a feeder coupled to the weigh hopper. Each weigh hopper measures the weight of material leaving it. The weighing system is programmed for simultaneous and proportional metering of each ingredient. Since each ingredient is weighed using an independent load cell, each cell can be sized and spanned to maximize the resolution of the A/D conversions. This yields very precise and accurate weightiness.

Typical Loss Weight – Target weight Blender – Multiple individually weight ingredients are fed simultaneously into a batch hopper or mixer to individual proportional weights. The batch is mixed and discharged to the downstream process.

• Stain gauge bridge sensors (one per component)
• 24 VDC Power Supplies

The metering feeders offer dual speed (bulk/dribble) operation for maximum throughput while maintaining high accuracy. Each ingredient is weighed and totalled. When a batch is completed, it is held until called for. This allows the system to be integrated with any existing process.

In 1984 Foremost patented the first Multi-Component Gravimetric Blender which controlled the blending process by weight rather than by volume. Continuous Loss in Weight Blenders (CLWB), functioning in a target rate mode, have been used in film and sheet extrusion for over 30 years. This configuration of gravimetric blender is arguably the most prominent in film and sheet production and probably for all extrusion processes combined. The popularity of this configuration for extrusion focuses on a few features that add up to widespread acceptance. Target rate gravimetric blenders are a natural extension of their predecessors, volumetric blenders, which were the earlier industry standard. The similarities are both in form and function. Compact, easily positioned on or above the extruder throat, continuously rate proportioning with a passive or no mixer, gravimetric target rate blenders are a natural, self calibrating, self correcting replacement for the previous generation of volumetric equipment.

Target rate gravimetric blenders have their major advantages over the other gravimetric technologies in terms of their cleanability, mechanical simplicity and ability to be easily integrated into a gravimetric extrusion control system. They are particularly well suited for film and sheet extrusion lines that operate with frequent, short product runs and with relatively quick response to changes in ingredient proportions is required.
