Generally, a screw feed device with flexible-walled/external-paddle-massaged screw trough is a first choice for loss-in-weight feeders
. However, there are situations where the stirring agitator is required:
Belt feeders, loss-in-weight feeders
and process controls includes line of 304 stainless steel belt feeders with feedrate capacities from 1 lb/min to 45 ton/hr.
Benefits include very low deflection and no moving parts directly exposed to the material, no interruption of flow, little or no field calibration, low maintenance, superior accuracy and lower cost than a loss-in-weight feeder
must be refilled during continuous operation, but they can't run in gravimetric mode while refilling.
The Force Measurement Suspension System is designed to provide higher accuracy in measuring weight using conveyor belt scales, weigh belt feeders, and loss-in-weight feeders
. Available in a number of capacity ranges and configurations to suit the needs of continuous weighing and feeding equipment, the system has proven effective in high-speed, high-volume to low-density, low rate applications where control quality and productivity are critical.
feed multiple components at the main feed throat to facilitate polymer/additive mixing in the early stages of the process.
The Bulk Solids Pump[TM] feeder line offers three models that can be configured as volumetric or loss-in-weight feeders
. Loss-in-weight BSP feeders can utilize either a scale or three-point suspension weighing as well as the company's Smart Force Transducer weighing technology.
will feed multiple components at the main feed throat to facilitate polymer/additive mixing in the early stages of the process.
Products include single/twin-screw volumetric and gravimetric feeders, Bulk Solids Pump (BSP) feeders, vibratory feeders, weigh belt feeders, liquid loss-in-weight feeders
, Smart Flow Meters, K4G gravimetric blenders in addition ot a complete line of Coperion K-Tron self-contained and central vacuum conveying systems, integrated controls and systems engineering services.
meter both the binder and filler feed streams into the extruder to maintain formulation accuracy.
Supplies loss-in-weight feeders
, screw feeders, twin-screw agitators, feeder controls and vibration trays.
Process Control Corp., Atlanta, is offering a new drive/gearmotor package for its auger-based, continuous loss-in-weight feeders
