Joy feeder-breakers provide a highly reliable, productive means for continuous feeding and breaking of most bedded, mined material – including wet, dry, sticky or a combination thereof – in a broad range of configurations for both surface and underground applications. The feeder-breaker is the connection between the mining system and material handling system, allowing both systems to operate at maximum efficiency and productivity. The UFB-17 feeder-breaker, designed for seam heights between 1,145 to 1,625 mm (48 to 64 in.), cuts your operating costs and increases your mine production by allowing your mining, haulage, and conveying systems to work at their most efficient rates. The UFB-17 is a highly mobile crushing solution to maximize your haulage productivity. Since the UFB-17 is located closer to the working face, haulage distances and travel times are kept to a minimum.

Designed for increased mine efficiency

  • Surge capacity allows haulage equipment to discharge mined material at the designed rate for such haulage equipment
  • Material throughput is fully variable up to 1091 tonnes (1200 tons) per hour
    • Optidrive variable frequency drive (VFD) system offers variable speed control equivalent to 25-100% of the rated throughput
    • Water-cooled and air-cooled drives available
  • Powerful rotary pick breaker, capable of fracturing material using up to 220 MPa (33,000 PSI) unconfined compressive strength, reduces mined material to a consistent, easily handled size
  • Steady discharge rate virtually eliminates spillage, while reducing belt wear

Designed for durability

  • All-welded frame construction helps reduce maintenance and lengthen working life  
  • Hard-surfaced chromium carbide deck overlay ensures long deck life
  • Alloy steel flights and shafting allow smaller sized components while still providing superb tensile strength
  • Breaker picks and pick force, designed for your requirements, handle tough material mixtures
  • High-strength conveyor chain, with hardened pins and bushings, delivers longer life, low maintenance, and increased dependability  

Designed for maximum mobility and performance

  • Available with optional Integrated Continuous Tramming (ICT) crawlers that include:
    • 20” crawler pads for lower ground pressure and improved traction in varying bottom conditions
    • A planetary crawler drive with reversible cap for free-wheeling capability
    • Designed to increase tractive effort for ease and speed of relocation
    • Maximum pad widths to ensure excellent flotation in all tram conditions
  • The breaker drives are electro-mechanical, direct-drive, utilizing robust geared drives for increased performance, reliability and availability.  

Designed for easy maintenance

  • Strategically located standard controls provide the easiest possible maintenance and troubleshooting
  • Bolt-on flights to allow easier installation and removal
  • Enhanced tail shaft designs for longer life
  • Longer life conveyor sprockets and chain
  • Spline mounted breaker and conveyor gear boxes for mechanical efficiency and ease of replacement 

Designed for your mining application

  • Intake ends, custom designed to meet your haulage needs, include ram car, swing gate, and three-way dump options
  • Staked or hinged sideboards come in various heights for additional capacity
  • Fully variable speed designs to match capacity to application
  • Spline mounted breaker and conveyor gearboxes with increased mechanical efficiency and ease of replacement

Designed for operator safety

  • Fire suppression
  • Centered control valves
  • Panic strip
  • Tram enable switches
  • Pull cords
  • Remote tram controls (radio and umbilical)

Optidrive VFD

Joy Optidrive (optional), an AC variable-frequency drive system, integrates software with the electronic and mechanical systems to provide the following features:

  • Conveyor speed control: Provides variable conveyor speed capability, allowing precise control of the equipment’s capacity
  • Breaker overload protections: Feedback circuit monitors breaker motor amps and regulates conveyor speed to protect from breaker overloads
  • The Joy Optidrive system, an AC variable-frequency drive system, integrates software with the electronic and mechanical systems to provide the following features:
    • Conveyor speed control - Provides variable conveyor speed capability, allowing precise control of the equipment's capacity
    • Breaker motor feedback – Electrical circuit monitors motor amperage and proportionally regulates conveyor speed to maintain breaker motor performance design
  • Capable of being fitted with a proximity detection system.
  • Enclosed tail shaft bearing assembly – extends the bearing life by lessening contamination from mud, coal, water, et cetera. (Options for UFB-14 and UFB-17)
  • Hydraulic conveyor chain take-up saves maintenance time and reduces labor and material cost. (Options for UFB-14 and UFB-17)
    • Quickly adjust the conveyor chain tension. (In approximately 2 minutes)
    • Properly tensioned chain extends the conveyor chain and sprocket life reducing cost and potential downtime.
  • Quick disconnect hydraulic pump easily disengages the hydraulic pump when the feeder-breaker (electro-mechanical conveyor) is not tramming. (Option for UFB-14 and UFB-17)
