This month's topic Solid Handling
Automated System Feeds and Transports Materials
The BFC Series weighing/batching system features bag activators that raise and lower the opposite bottom edges of a bag at timed intervals, loosening compacted materials and promoting material flow. Each discharger is equipped with a surge hopper that discharges into an enclosed flexible screw conveyor. A controller starts and stops the conveyors to weigh ingredients in sequence, first at a high feed rate for rapid filling, then at a dribble, stopping flow when the desired weight has been discharged. The controller then activates a rotary airlock valve to release the batch into a pneumatic conveyor line, which terminates at a filter receiver above a ribbon blender. Components are made from carbon or stainless steel.

Checkweigher is Easy to Operate
The Beltweigh/S Combo Checkweigher combines the new S Series controller and a Safeline metal detector. The Beltweigh/S operates at speeds up to 350 ft/min to handle up to 500 containers per minute, while consistently maintaining accuracies of ±150 mg at 2 sigma. The Safeline metal detector provides integrated protection against all types of metal contamination. A touch-screen operator control features user prompts, intuitive menu systems, graphical data displays and visual interpretations of machine performance that simplify use and improve machine integrity.

Monitoring System Warns of Poor Screen Performance
SentryScan uses microwaves to detect most breaks, holes or tears in a separator’s wire-mesh screens. The device emits a low-power microwave signal that is blocked by woven metal screen mesh. When a break in the screen occurs, the receiving module detects a signal change and triggers an alert, which the operator can choose to receive as a warning light, audible alarm, or remote signal sent to a central process control system.

Electromagnetic Shakers Fit in Small Spaces
Impulse Compact electromagnetic shakers are designed specifically for tight-fitting processing and packaging lines. Dedicated solid-state controls allow conveying pan amplitudes to range from zero to 100% to adjust for different products or conditions. The shakers can be adjusted from low-stroke/high-cycle mode for gentle product handling to high-stroke/low-cycle mode for faster throughput of heavier products. Sizes range from 200 to 400 mm wide and 1,500 to 2,000 mm long.

Laboratory Provides Electrostatic Testings of FIBCs
Handling dry products in flexible intermediate bulk containers (FIBCs) can produce electrostatic discharges, which in a flammable atmosphere can result in an explosion. This laboratory offers testing of FIBC containers and liners to determine surface resistivity, volume resistivity, brush discharge, and fabric charge relaxation times. Explosion chambers are used to determine an FIBC’s effectiveness in hydrocarbon/air environments. The facility has climate-control capabilities with a temperature range of 40–140°F and humidity range of 0–99% RH.

Flexible-Screw Conveyor Handles High Throughput
With a maximum output of over 44 ton/h, the 834 flexiblescrew conveyor (FSC) can convey at inclines up to 60 deg. at 100% full capacity, while competitive rigid-screw conveyors top out at 30–40 deg. and convey at only 30–45%. Other advantages include continuous mixing of product and variable-speed drives for accurate metering. The 834 FSC is available in carbon or stainless steel.

Small Media Mill Can Operate in Continuous or Circulating Mode
A 1/2-L tank-sized mill, the DMQ- 05 has ring screens that can be adjusted to accommodate the use of grinding media from 1 mm to as small as 0.3 mm. Proprietary Delta discs eliminate shaft whip and mill vibration, while providing greater random media motion for improving milling efficiency. The discs are indexed to provide directed and uniform media distribution throughout the mill chamber.
