Feeding devices

Where the scale activates an output, iadicating that the desired weight has been achieved, the feeding equipment must stop operating immediately. Some feed devices may need a brake to eliminate coasting. Even if a feeder stops iastanfly, there will be a certain amount of material added to the... 

Feed Size. The acceptable feed size for a given machine is governed by the type of feed device and physical characteristics of the machine. 

Sanitizer and Chemical Feeders. Eeeders dispense the chemicals in gaseous, Hquid, and soHd (both granular and compacted) forms. Many health departments require that pubHc pools have approved feeding devices for the daily appHcation of all chemicals, including saniti2ers. A slurry feeder for diatomaceous earth (DE) on diatomite filter installations may also be required. 

Feeding devices, stirring, and baffles all produce material flow that contributes to convection. Material flow between surfaces moving at different velocities... 

The burden must have a definite sohdification temperature to assure proper pickup from the feed pan. This limitation can be overcome by side feeding through an auxiliary rotating spreader roll. Apphcation hmits are further extended by special feed devices for burdens having oxidation-sensitive and/or supercoohng characteristics. The standard double-drum model turns downward, with adjustable roll spacing to control sheet thickness. The newer twin-drum model (Fig. ll-55b) turns upward and, though subject to variable cake thickness, handles viscous and indefinite solidification-temperature-point burden materials well. 

Agglomerate breaking and liquid feeding device shown in broken line. Where no liquid feeding is necessary, a pin-type agglomerate breaking device is used. Tumblers of this type are available plain or with any of the above features. 

With few exceptions, treatment technologies are limited to some extent by the size of the material that they are able to process. These limitations can apply to the throat of the feed devices, the inner workings of the equipment, the treatment mechanisms, or the process elements. To make these remedial technologies efficient and cost effective, separation techniques are used to make the feed stream uniform...

Type of loading. A simple static load is relatively easy to recognize, but there are cases that fail between impact and suddenly applied loads. One thus takes into account infrequently applied fatigue loading mixed with some shock loads, as for example cams, links, or feeding devices. 

Offset Printing Roll-transfer method of decrating. In most cases less expensive than other multicolor printing methods. Ranges from low-cost hand presses to very expensive automated units. Drying, destaticizers, feeding devices. 

The alkanesulfonate melt is treated with 4 bar of water to give a paste containing 60% active matter (12) or pelletized by means of a cooling conveyor with a special feeding device (not shown in Fig. 2). The solid product is composed of 93 wt % of alkanesulfonate, 6 of sodium sulfate, and 1 of paraffin.

Simple systems requiring a prime mover, a feeding device, a conveying pipeline and a cleaning or disengaging device (Marcus et al., 1990). 

The apparatus is an electronic, liquid-bome particle-counting system that uses a light-obscuration sensor with a suitable sample feeding device. It is the responsibility of those performing the test to ensure that the operating parameters of the instrumentation are appropriate to the required accuracy and precision of the test result.

A fluidized bed is made up of a mass of particles buoyed up out of permanent contact with each other by a flowing fluid. Turbulent activity in such a bed promotes high rates of heat and mass transfer and uniformity of temperature and composition throughout. The basic system includes a solids feeding device, the fluidizing chamber with a perforated distributing plate for the gas, an overflow duct for removal of the dry product, a cyclone and other equipment for... 

The bulk flux of solids in a standpipe depends not only on the geometry of the standpipe but also on its feed devices and flow control valve, located at the top and bottom of the standpipe, respectively. The flow pattern of solids in the pipe may vary with the pipe distance, depending on the variation of the slip velocity in the pipe, uzp — uz. The effect of gas compression due to pressure increase may also be very significant. As a result, p varies along the standpipe, which in turn changes a and, consequently, the slip velocity. Thus, for a standpipe flow, it is possible that several flow patterns exist in various axial locations as solids travel through the standpipe. 

As mentioned, the flow rate in a standpipe depends on the solid feed device as well as the flow control valve. In this section, we discuss the gas-solid flows in a simple standpipe system where the feed device is a mass flow hopper and the solid flow regulator is a discharge orifice [Chen et al., 1984]. As shown in Fig. 8.15, the entrance of the vertical standpipe is connected to a conical hopper feeder of half angle solids flow patterns are considered. One is a dilute suspension flow, and the other is a solid moving bed. In this case, the following additional assumptions are needed ... 

A last advantage of this feeding device is that it can be constructed at any length desired and also that the same trickle feeder will take a narrow or a wide curtain without needing any adjustment.
