Presumably as the workers lap it up they may be induced to feed the queen at the same time so starting the acceptance process. Best regards Elaine. D.A.C. As an observant beekeeper of over 50 years experience, with a fairly large number of colonies, I have very rarely seen "balling" and then only when I tried to introduce a queen directly.

This mixture is blended together in a mixer and fed to balling discs or drums to produce green pellets of size typically about 9-16mm. The green pellets are then fed to the induration machine. Both straight grates and grate kilns dry the pellets out in a drying section, then bring the pellets up to a temperature of about 800-900 °C in a ...
Jan 22, 2020· The refractory kiln blocks are 9″ deep in this photo while in the feed end of the Kiln they are 6″ deep. The Kiln burner has a capacity of 500. gph of No. 6 oil, heated to 230° at a pressure of 350 psig. Each kiln is driven by a 100 HP D.C. motor which results in a …
The process includes feed preparation (grinding & pre-drying), mixing with the binder, balling by a disc pelletiser & hardening by drying, pre-heating, firing & cooling. Magnetite ore concentrate gets re-converted into hematite ore in the pelletisation, as it is an oxidation process. ... When used in the rotary kiln, pellets reduce the iron ore ...
Aug 30, 2013· What is the reason of kiln feed balling, what operational steps can be taken to reduce the balls formation ? Are there some modern means to break boulders inside … Ring Formation – …
The prepared feed pellets were fed continuously to a refractory lined, rotary kiln at the rate of 600 lbs/hr. The kiln was 23/4 ft in internal diameter and 30 feet in length. The kiln was fired by a natural gas burner, with the gases passing counter current to the solid feed. The kiln rotation speed was 3 rpm and the slope was 1/8 inch per foot.
For stable kiln operation and to obtain uniform quality of clinker it is necessary to keep the variation in kiln feed in LSF 0.5, in SM 0.03 and in AM 0.03 measured as a standard deviation. A specific blending operation is therefore necessary to produce kiln feed of quality that is consistently uniform in chemical composition and also particle ...

The balling disc basically consists of a pan with a peripheral wall, which rotates with a certain inclination to the horizontal . In general, in a balling disc, the pan angle can be adjusted between 40 and 60 . When the disc rotates, the feed material with less moisture than that required for the pellets
Improved productivity and efficiency of the rotary kiln & Blast Furnace with superior reducibility behaviour of pellets compared to lump ore. ... Balling drum size Size has been increased to 5 m dia with an output of over 200 ... 8 mm. HPS feed consists of iron ore as pellet feed fines, return fines and …
FEECO Balling Drum. Balling drums consist of a large, cylindrical "drum," through which the material tumbles to promote agglomeration. Much like the disc pelletizer, binder and feedstock are continuously added and particles pick up additional fines as they tumble through the drum, which is set on a slight angle to allow gravity to assist in moving pellets through the process.

Jul 22, 2017· 1. the nature of the material can affect the balling. Different materials have different physical and chemical properties, having great influence on the balling quality. For example, the components of ball clay have great influence on the balling quality. If coarse grained quartz sand is contained in the ball clay, the balling quality may be bad.

Feb 28, 2020· 3. Low feed is dangerous and special attention need to be paid to any temperature fluctuations in the preheater cyclone . 4. If the kiln remains dusty and flushing, the kiln need to feed off and than empty the kiln drive and once the kiln amps is at normalempty range. take feed back .
Pelletizing of animal feeds can result in pellets from 1.2 mm (0.047 in) (shrimp feeds), through to 3–4 mm (0.12–0.16 in) (poultry feeds) up to 8–10 mm (0.31–0.39 in) (stock feeds). The pelletizing of stock feed is done with the pellet mill machinery, which is done in a feed mill.. Preparation of raw ingredients. Feed ingredients are normally first hammered to reduce the particle size ...
