Coal Feeder Gates & Valves

02 models
Feeder Inlet ValveGATE

Feeder Inlet Valve

Inlet isolation valve that shuts off material flow into the feeder for safe maintenance and clean changeovers.

Inquire
Double Slide Gate ValveGATE

Double Slide Gate Valve

Twin-blade slide gate for positive, leak-tight isolation of bulk material at the feeder inlet or outlet.

Inquire

Retrofitting a coal feeder?

Share existing feeder model, inlet arrangement and maintenance problem. We will help identify the right gate or upgrade path.

Request support
Not sure which feeder arrangement fits?

Send material, particle size, moisture, desired rate, accuracy target, inlet height, outlet conditions and plant constraints. Flowtork can help compare belt scale, weigh feeder and coal feeder gate options.

Frequently asked

Weigh belt & feeder questions, answered.

Quick answers to the questions our engineers hear most often. Still unsure? Send us your application details and we’ll confirm the right choice.

How do I know which feeder system is suitable for my application?
Selection depends on the material handled, feed rate, belt width, capacity requirement, accuracy requirement, site layout, process conditions, and control system requirements.
What details should I prepare before inquiring about a feeder?
Helpful details include the material, bulk density, required feed rate, capacity range, belt width if existing, installation space, power supply, control signal, and current feeder details if for replacement.
Why is accurate feeding important in industrial processes?
Accurate feeding helps maintain process stability, improve efficiency, reduce material waste, and support consistent production or combustion performance.
What should be checked when replacing an existing weigh belt or coal feeder?
The existing feeder model, belt size, capacity, motor details, control system, installation dimensions, material characteristics, and site limitations should be reviewed.
Are spare parts available for weigh belt and coal feeders?
Spare parts may be available depending on the brand, model, and feeder configuration. Common parts may include belts, rollers, pulleys, load cells, speed sensors, controllers, motors, bearings, and other wear components.
What maintenance is needed for feeder systems?
Maintenance may include belt inspection, calibration checks, load cell inspection, belt tracking adjustment, cleaning, lubrication, motor checks, controller checks, and verification of feed rate accuracy.
What can affect feeder accuracy and performance?
Accuracy can be affected by belt condition, material buildup, calibration issues, load cell condition, belt tracking, vibration, material flow behavior, and maintenance condition.
Can feeder systems be integrated with plant control systems?
Yes. Depending on the system configuration, feeders can be integrated with plant control systems for monitoring, speed control, feed rate control, and operational feedback.
