126.96.36.199 – Photo/Graphic TBDAs a major contributor to formulation quality and consistency, feeder performance rightly deserves close attention and concern.
188.8.131.52 – PhotoFaced with several alternatives, making any rational purchase decision simply means making the best possible selection at the time it has to be made.Often what makes capital equipment purchase decisions so challenging is not just the complexity of the particular issues involved or the underlying mechanics of decisionmaking, but all the residual uncertainties of fact and assumption that linger even after months of careful investigation, evaluation and consideration.“Did we include all the factors that should go into this decision?”… “Did we account for them fairly?”… “Did we accurately estimate projected costs and savings?”… “Should we do more before we decide?”… these and other questions reflect the nagging doubts that confront any equipment buyer.While uncertainties will always exist, working within a logical and comprehensive decision framework will help assure the firmest possible footing in navigating the purchase process.
184.108.40.206 – Photo 220.127.116.11 – Quality & Efficiency ContributorsBecause of the uncertainties and practical difficulties involved in performing a rigorous pre-purchase estimates of Total Cost of Ownership (TCO), a less formal yet more practical approach may still provide the guidance needed to fairly support the purchase decision.

126.96.36.199 – Photo 188.8.131.52 – Efficiency ContributorsWhile the impact of quality-related cost factors are proportional to process throughput, efficiency contributors impose their costs or deliver their benefits over time by influencing process efficiency in various ways.

18.104.22.168 – Photo 22.214.171.124 – ArtWhere the material’s handling characteristics are too challenging for one screw, two screws operating side by side often provide the needed solution whether for floodable or hard to flow materials.The basic twin screw design employs a pair of milled, concave-profile screws set 90o out of phase with each other so they fully intermesh.

22.214.171.124 – Photo 126.96.36.199 – ArtRotating material halfway around a circle gives the rotary valve an advantage similar to the twin screw and Bulk Solids Pump approaches: that of capturing material in a confined space, moving it to another point, and discharging the load.Rotary valves, also referred to as rotary airlock feeders, rely on gravity to receive and discharge material.
188.8.131.52 – PhotoIn the context of application in the loss-in-weight feeding of critical liquids, slurries or pastes whose specific gravity varies sufficiently to warrant gravimetric flow control, a holding tank and pump or control valve replaces the standard hopper and metering device combination required in the feeding of solid materials.Because loss-in-weight feeding involves weighing the entire material containment and handling apparatus, the type of pump or control valve employed becomes irrelevant.

188.8.131.52 – Photo 184.108.40.206 – ChartTo assure a consistent, reliable flow through the supply hopper and into the feeder’s metering element, hopper agitation or other flow aid strategies may be required, depending on material.Proper bin design, the first step in promoting flow and avoiding potential difficulties, can be augmented by other, optional or add-on solutions including bin activators/dischargers, mechanical agitators, flexible hopper liners, air pads, injectors and blasters, hopper vibrators, and polished and coated hoppers.
220.127.116.11 – PhotoBypass ChannelA bypass channel allows the meter to be tared at any time during the measurement process.
18.104.22.168 – RepeatabilityRepeatabilityThe performance statistic most familiar to feeder users, repeatability quantifies the degree to which a feeder’s discharge stream varies over brief time intervals, producing a snapshot of one dimension of feeder performance.Note that the repeatability measurement says nothing at all about whether the feeder is delivering, on the average, the targeted rate (that is the purpose of the linearity measure performed on a properly spanned feeder). Repeatability does, however, reveal a great deal about the expected extent of short-term flow-rate inconsistencies, an important contributor to the integrity of the formulation and end-product quality.The repeatability measurement is performed by taking a series (usually at least 30) of carefully timed consecutive catch samples from the discharge stream, weighing each, and then calculating the + standard deviation of sample weights expressed as a percentage of the mean value of the samples taken.
22.214.171.124 – Timescale GraphicAn issue of growing importance in the specification and measurement of feeder repeatability relates to catch sample duration.
126.96.36.199 – Linearity GraphicAssuming a properly spanned feeder (a calibration scaling process resulting in measured and requested feed rate being equal at a specified operating rate), a feeder’s linearity measurement quantifies how well it delivers, on the average, the targeted discharge rate throughout the feeder’s complete operating range.Perfect linearity is represented by a straight-line correspondence between the setpoint and measured average feed rate throughout the feeder’s specified turndown range from its design full-scale operating rate.(4942 placeholder)To perform a linearity measurement, several groups of timed catch samples must be taken from the feeder’s discharge stream.
188.8.131.52 – Stability GraphicA perfectly performing feeder is worth little if it can’t maintain its performance over the long haul.Historically, many factors contributed to performance drift such as feeder type, analog control and weigh systems, the feeder’s mechanical systems, maintenance, and the operating environment itself.

Visitors to the recent NPE 2009 show in Chicago were looking for materials handling equipment that could do more than dry, blend, or convey resins. It had to do those things while saving energy, providing faster and easier maintenance, speeding product changeovers, reducing labor cost, minimizing waste, and providing better value for money. The new products cited below addressed those needs and more.
A new hopper vibrating unit is said to prevent bridging and rat-holing of cohesive, hard-to-flow bulk materials in stainless-steel hoppers.
