Powder grain size shall be around 200 mesh. The powder agitator, in turn, has a geared portion such as the toothed disc 21 and agitator bar means which may be in the form of upstanding iingers 22 rigidly secured therewith for rotation Within the hopper 16.In order to keep solid powder flow into the processing tube smoothly under a controlled atmosphere, you may need a tube flange with a KF25 opening (pic.2).You may connect this feeder with a rotation furnace to achieve solid powder feeding automatically (pic.1).The conical shape allows the simple forces. Elgin's hydrofoil agitators feature: High flow efficiency, low power consumption, and lower operation costs. NRTL certification is available upon request. Container Mixer Hoppers: Reliances Container Mixer Hoppers are specifically designed to aid the mixing process. Compared to standard agitators, on the market today, Elgin's hydrofoil design nearly doubles the mixing capacity at any impeller size.Outside Dimensions: 220mm L x 220mm W x 202mm H.pressure: 0.2 bar （ High-pressure powder feeder up to 1 MPa is available at the extra cost. Note: The customer may cut the feeding screw into a shorter length if needed. 28'' long feed screw for efficient power delivery.Feed rate adjustable by the potential knob at the range 0 - 97 ml /min max.Stainless steel hopper with the vibrator.RPM can be adjusted based on the Gearbox ratio, motors RPM will be either 1475 or 2900, usually motors with 1475 RPM. of agitators Z x rho / D, Z - reaction mass height, rho - density, D - inner dia of reactor/vessel. Note: Upgraded feature - timing control for the external vibration device is added in June 2016. Regarding an agitator design all you can do is managing the L/D ratio, simply sweep dia you have to fix, then no of agitators, these can be calculated based on a formula, No. The material is conditioned to a uniform bulk density, evenly filling the flights of the feed screw, eliminating rat-holing and bridging which can cause clogging and buildup of materials. It is designed for feeding solid powder into a furnace for continuous firing/heat treating with air-tight. This is important in the design of hoppers, since for mass flow. As standard the feeders are supplied with a hopper storage volume of 100ltr however the capacity can be tailored to suit your specific capacity requirements.EQ-PF-1S is an air-tight automatic solid powder feeder that includes a motor-driven agitator and stainless steel hopper with a built-in vibrator. In some instruments, the vertical force on the agitator can also be directly measured. The feeders can be manufactured from carbon steel, grade 304 stainless steel and grade 316 stainless steel, with options also, for ATEX Cat 3D feeders suitable for use in a ATEX Zone 22 area. Also, a mechanical rotating agitator minimises fluctuations in bulk density, in comparison to air or vibratory discharge aids, which is an important factor when considering a gravimetric feeder as variations in bulk density distort the accuracy of the feed rate.Ī screw conveyor is used to control the feed rate from the feeder and offers transfer rates from 25kg/hr up to 3000kg/hr. The rotating agitator is a very efficient method for handling cohesive powders prone to bridging and rat holing. TB30 features a new hopper-valve-agitator design ideal even for harsh concrete. Mechanical rotating agitator standard on both product rangesĪs standard, both feeder options incorporate a mechanical rotating agitator to act as a bridge breaking device to aid positive discharge before entering the screw conveyor. The last and final hopper design ended up being a very simple agitator that spins using the same motor that spins the disc. New hopper-valve-agitator design for TB30 High level performance with all sort of concrete and low operating costs.
Visual controls and inspection standard for operators were also developed for control purposes. The gravimetric feeders can be used both as gain in weight or loss in weight feeder. design of agitator in hopper and design of weight scale. Spirotech’s standard volumetric feeder design incorporates high and low level probes for basic hopper refill and the standard gravimetric feeder design incorporates loadcells for hopper refill and can provide continuous or batch weighing to suit your specific application. Spirotech Group Ltd manufacture a range of volumetric and gravimetric feeders, bespoke to suit your exact requirements, to accurately and reliably feed various powder or granular products.
