Stamle feeder breaker, designed for low-to-high seam applications, provide high productivity and reliability in the most rigorous of conditions. Each feeder-breaker is designed to work as an integral part of your total mining operation. It allows mining, haulage and conveying systems to work at their most effi cient rates to maximize mine production.
Designed to work as an integral part of your mining operation
The basic elements of each Stamle Feede Breaker are similar in design, following decades of engineering design philosophies and fi eld performance. Each machine begins with robust, all welded frame construction. The conveyor deck is hard surfaced with chromium carbide overlay adding long deck life to the unit. All fl ights and shafting are made from alloy steel, allowing for smaller sized components at a high tensile strength. Controls and components are located for safety, ease of troubleshooting and maintenance.
Designed to increase your mining efficiency
•Surge capacity allows the Stamle Feede Breaker to discharge mined material at the maximum capacity of the haulage equipment
• Material throughput is fully variable up to 2,000 TPH (1814 tonne)
• Powerful rotary pick breaker reduces mined material to a consistent, easily handled size
• Mined material is discharged at a steady rate, virtually eliminating spillage and reducing belt wear
• Available with optional Integrated Continuous Tramming (ICT) crawlers. The heavy-duty frame construction includes a planetary crawler drive with reversible cap for free wheeling capability.
Designed for maximum mobility and performance
Each feeder breaker has the same basic confide duration - hopper, breaker, and conveyor. By varying these three aspects of the confide duration, we can match our equipment with the application. We offer several options for increased mobility, lower ground pressure and improved traction in varying bottom conditions.
Intake ends are designed to meet customer preferred haulage means. Ram car, swing gate and three-way dump intake ends can be custom-designed to accept discharge from specifi c haulage equipment such as ram cars, scoops, shuttle cars and battery-powered haulers. Staked or hinged sideboards are also available at various heights for additional capacity.
The breaker shaft, components and drives on the UFB-14 and UFB-17 are designed to produce forces capable of fracturing material up to 33,000 PSI (220 MPa) unconfi ned compressive strength. Direct drive breaker and conveyor systems are both standard on Stamle Feede Breaker. These designs reduce maintenance time and spare parts stock by eliminating drive chain, sprockets, and drive chain tensioning requirements. Both hydraulic and electro-mechanical conveyor drives are available on both models.
A “feedback” circuit enhances the performance of both hydraulic and mechanical conveyor drives. The “feedback” circuit monitors loads seen by the breaker shaft and automatically adjusts the conveyor speed to provide optimum operation and reduce potential overloads.
Designed to reduce downtime and increase production
Enclosed tail shaft bearings option
Stamle Feede Breaker intake ends are available with our enclosed tail shaft bearings design.
• Extends bearing life up to four times longer
• Reduces downtime
• Increases production
Design includes alloy steel shafts, improved contact seals (three degrees of separation from contaminants), a larger bearing and several levels of bearing protection from water and contamination. Field retrofit-kits are available to upgrade existing machines with slight frame modifi cations
Optional bolt-on flights
Conveyor flight replacement is quicker and easier with our bolt-on, alloy steel fl ight design. With this option, operators have the flexibility to add additional flights and improve product sizing. Instead of the welded fl ight end design, four bolts hold each fl ight in place. No special conveyor chain links are included and there is no need to remove chain covers. The new design also retrofits with standard conveyor chain. Downtime to replace flights is reduced by up to 75%.
Optional hydraulic conveyor chain tensioning system
Chain take-up tension can easily be adjusted without removing covers on the intake end and manually adjusting the chain. With less downtime during change-out, the machine is put back in service more quickly.
• More robust design with fewer parts to fail
• Tensioning is more accurate, leading to improved machine performance and increased component life
• Under normal conditions, chain adjustment time is reduced from two hours to two minutes The system is capable of providing the optimal conveyor tension without over-tensioning the chain under normal operating conditions.
Stamle Feede Breaker
Operators benefi t from our simplifi ed and more robust connection, fewer parts, less labor and less space needed for removal. With less downtime during change-out, the machine is put back in service more quickly and is therefore more productive. By moving to a splined connection versus a compression connection, assembly and disassembly time is reduced more than 50%. Available space for drive removal and installation is increased, making repairs easier. Actual splined connection is 25% stronger than previous connections, while maintaining ability to disassemble when required.
