Lime Feed Systems
Series 32-300 Volumetric Screw Feeder
The Series 32-300 Screw Type Volumetric Feeders are designed for the demands of municipal and industrial-process applications. They meter dry and semi-dry pebble lime with reliable accuracy and repeatability. The heavy gauge steel construction stands up to the stress of long-running, high-volume bulk operations. Operation and control are simple and direct. There are only five moving parts. Power from the vertically mounted AC motor is transmitted through a right-angle gear reducer to the feed-screw shaft. A potentiometer or touchscreen entry on the main control panel sets the feed rate. Automatic control from a remote signal is available. Oversize sealed ball bearings support the one-piece, through-shaft at both ends. Interchangeable feed screws in four sizes extend the versatile capabilities of these feeders. The standard hopper with steeply sloped sides is designed to promote an even flow of lime to the feed screw.
KEY BENEFITS
• Heavy gauge construction
• Simple design
• Convenient controls and readouts
• Easy to maintain
• Smooth handling of difficult lime flows
FEATURES
Versatile
Four screw sizes are available for capacities up to 133 cubic feet per hour. The feeder can be controlled manually or by a remote signal. The basic feeder can process lime at temperatures to 150° F.
Reliable Performance
The simple, direct mechanical linkage has only five moving parts (drive, coupling, screw, and two bearings). Power from the vertically mounted AC motor is transmitted through a right-angle gear reducer. The feed screw is directly coupled to the gear reducer.
Simple Maintenance
A removable clean-out hatch is provided on one side of the hopper for easy cleaning and access to the feeder screw.
Structural Strength
Heavy gauge steel is used throughout. Feed-screw shaft is a single-piece through-shaft and is supported at both ends by sealed ball bearings. Metering screw segments are all welded to the shaft for strong unitized construction.
Simplified Control
Feeder controls are centralized in a NEMA 4 enclosure with flexible mounting locations. Toggle switches set the operating mode. A potentiometer
controls feed rate, and an analog meter provides readout of feed rate in percent of full scale.
DESIGN AND OPERATION
The Series 32-300 Volumetric Feeder is powered by a VFD-controlled AC motor. A gear reducer converts the high speed motor-shaft rotation to a low speed, high-torque drive for the feed-screw shaft. Sealed ball bearings support the single-piece through-shaft at both ends. The standard hopper has a capacity of 1.5 cubic feet and steeply sloped sides for good lime flow to the feed screw. A hopper vibrator is available for lime with poor flow characteristics. All controls are housed in a NEMA 4 enclosure with flexible mounting locations. A potentiometer enables accurate pre-setting of the feed rate and excellent repeatability.
