Advantages: • Operator Peace of Mind At the end of a day’s work, operators need only check teeth. No welding or checking bolts. The operators can feel comfortable if their machine hits a hidden structure under the pavement.
• No welding - No bolting of blocks The design of the flighting (smooth continuous section) allows the drum to roll over any steel objects it hits. Only breaking teeth, not blocks or gear boxes. • Down time minimised when hitting pits Just tap out the broken tooth out of its insert and replace it. • No loss of edge blocks The edge cutting blocks form part of the flighting, so the whole flighting has to be worn down to have any effect on the replacement tooth. • No loss of accuracy on Tooth Pattern Schibeci blocks are made of ultra high strength materials, so there is very little wear over a season of operations. Because the blocks don't break off, there is minimal variaton in height of the cutting tool. Therefore, the pattern remains consistent throughout the life of the drum.
• Well Balanced design Every drum Schibeci produces is computer balanced on jigs before they are placed in machines. Each tooth impact time is equal to the next, reducing vibration and maximising power efficiency of the milling machine.
• Tooth pattern balances HP use across drum This balance is achieved by distributing impacts accross the drum so tooth horsepower requirements are transferred evenly across the drum. There is no spiking of horsepower or sideways drag. • Low friction coefficient Fluid Dynamic As the flighting is the tooth holder there is no friction caused by tooth holders protruding above the flight. The material flows easier into the auger and travels in the auger smoothly. • Excellent tooth rotation and changing The angle set in manufacture is constant for the life of the drum. The rear of the insert is protected from any material entering into the retainer spring area. • Able to cut reinforced concrete, Bluestone, Heavy Limestone Many projects have been completed with the Schibeci Drum, with reinforced concrete strength to some 9,000 psi, and limestone to 15,000 psi. In these processes only carbide was shattered or teeth broken. • Less Material at end of cut due to higher flighting Due to the increased flighting height, the flight is closer to the cutter box housing, so there is less material left in the cutter area at the end of each run. • Annual Maintenance only The only serious maintenance is if flighting segments have excessive wear on them that they need to be replaced. Replacement time is between 4 and 10 minutes each per upper Block. • Better Fuel Economy Documentation is available to show that the design criteria reduces the amount of fuel used.
