THERMAL POWER PLANTS: COAL HANGUP IN BOWL MILLS
Bowl mills are used for pulversing coal in pulverized coal fired boilers. The coal to the mill is fed by a coal feeder from the coal bunker. There are many type of feeders used for coal feeding like the belt feeder which can be in volumetric or gravimetric mode, the chain link feeder, the drag feeder, etc. Row coal from the yard is sized in crushers and stored in coal bunkers.

Plugged Chute Detection Probe - 911metallurgist
Plugged Chute Detection Probe. A Plugged Chute Detection Probe is an emergency switch that will shut down the equipment should a transfer chute "become plugged. There are two common types of probes, a TILT SWITCH and a CONDUCTIVITY switch. A tilt switch hangs inside the chute. If the chute plugs, the ore will build up to the switch.

Plugged Chute Detector Solutions: Monitor Technologies
Depicted here are some of the more common methods for plugged chute detection. Microwave Solids Flow Detector, model SFD-2 or SFI employed to monitor the flow or no flow state of the process material. Non-intrusive monitoring of flow condition. The SFD-2 or SFI cannot differentiate between a plugged no flow condition and an empty no flow condition.

Prevent Material Blockages - Martin Eng
These accumulations choked the flow of material, reducing the plant's production from its design rate of 3,000 to 2,700 tons per day. To regain capacity, the plant would take unscheduled outages to allow manual cleaning of the ducts. After cleaning, the buildup …
Design of Coal Transfer Chutes - bulk-online Forums
A copy of the Chute Design Seminar may be difficult to locate. It was a limited edition - only 500 copies were sold in South Africa. Chute design is not well covered in the conveyor design handbooks. The only book I know on real chute design was written by Dick Stahura of Solid Systems Engineering Co in Colorado USA.
Transfer Chute-- Problem ( Cause and solution required)
Transfer Chute-- Problem ( Cause and solution required) Dear Sir, We are operating coal handling system for 5 X 660 MW, SCTPP and handling around 50000 MT coal on daily basis through wagon tippler and stacker reclaimer. In our our uncrushed zone we are facing huge problem on chute for liner plate and mother plate dmages.

Coal Hang-up in Bowl Mill Operations - Bright Hub Engineering
Specific causes. The reasons for coal hang-up to mills can be many, like large raw coal size, jamming of the feeder, jamming of the coal chute from the bunker due to high moisture in the coal, foreign material at raw coal inlet to feeder, etc. Plant responses. The boiler fuel input coming down due to coal flow hang-up the mill slowly gets unloaded.
