Feeder breakers Joy UFB-33

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-33 feeder breaker, designed for seam heights greater than 1,372 mm (54 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-33 provides a highly mobile crushing solution to maximize your haulage productivity. Since the UFB-33 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 its maximum rate
• Material throughput is fully variable up to 1,000 tonnes (1,100 tons) per hour
  • Optidrive variable frequency drive (VFD) system offers variable speed control equivalent to 25 to 100% of the rated throughput
  • Water-cooled and air-cooled drives available
• Powerful rotary pick breaker, capable of fracturing material using up to 200 MPa (30,000 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 means low maintenance and long 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 long life, low maintenance, and superior 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 maximize 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 maximum 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
• Replaceable modular frame sections

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

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, 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
• Prevents breaker overloads:  Feedback circuit monitors breaker motor amps and regulates conveyor speed to prevent overloads
