MTP's automated nut applicator and nibbing machines can process up to 480 tons of roof bolts per month. (Based on 20mm bar, 1800mm long, a single shift of 8 hours. 22 work days per month and 75% operator and loader efficiency). Automated nut applicator and nibbing machines consist of a sorting and loading table which insures the correct positioning of the bars, a vibrating nut sorter to supply the nut applicator, which in turn spins the nuts onto the thread, a nibbing press with a backstop to accurately position and nib the threads and a spinning head to spin the nut back onto the nib. Oil filtering system with magnetic separator for removing bar scale. Safety guards.
