RIDGEWAY, SC — The 350-hp (260-kW) class BOMAG BM 1200/35 cold planer on display at CONEXPO-CON/AGG 2020 featured new BOMAG ion dust shield technology for effective removal of fine dust and particulate matter generated by the milling process. Alternative solutions for particulate matter removal simply vacuum the dust from the immediate working area and discharge the particles onto the conveyor belt. While protecting the driver and ground man, these systems to do not fully eliminate particulate matter, which can remain in the operating area and slowly settle back onto the equipment and ground.
The BOMAG ion dust shield solution for cold milling machines captures fine dust and particulate matter and turns it into coarse dust. The full extraction system is housed in a small box installed on the conveyor belt. Captured fine particulates move through an electric field that positively charges the particles, which are attracted to the negatively charged housing. This process permanently clumps together fine particles, forming course dust that is ejected into the truck along with the millings.
The MTU (Mercedes) diesel engine powering the BM 1200/35 uses a combination of exhaust gas recirculation (EGR) and selective catalytic reduction (SCR) to offer the lowest emissions among 3.3-ft (1-m) mills. The 350-hp (260-kW) machine offers 16% more engine power and 11% more torque than competitive units to improve milling efficiency. A sound insulation engine compartment lowers engine noise levels to improve operating comfort.
Featuring the innovative BOMAG cutter system that lowers wear, increases productivity and reduces fuel consumption, the BM 1200/35 cold planer offers a 47.2-in (1,200-mm) cutting width and maximum 13-in (330-mm) cutting depth. Three drum milling speeds of 85, 95 and 107 rpm let the operator tailor cutting speed to jobsite conditions. The exclusive BMS 15 interchangeable tooth holder system has a single bolt for holder retention and requires just 75 ft/lb (100 Nm) torque to tighten, which is up to 80% less torque than competitive designs.
The mill’s operator platform is built for operator comfort and productivity. Its 45-degree swiveling seat gives the operator excellent visibility of the rotor’s cutting edge, while rubber vibration buffers between the mill’s frame and operator’s platform minimize machine vibration feedback to improve comfort. The operating console swivels with the seat and features logical control configuration to minimize training and avoid operating errors. Automatic engine speed control, load control, traction and water spray help to improve milling efficiency.
