The latest version of Surface Tech’s Micro Doser system, the MD3, takes the process of mixing ACE Fibers into produced asphalt to a new level. Most notably, an improved onboard computer interface now allows operators to specify either 19mm or 38mm sizes of ACE Fiber to feed through the system. While the MD3 still allows for either bulk or sprinkle feeding, the new size-specific setting yields more exacting data and further improves the system’s efficient and thorough distribution of fibers.
An added feeder tray and improvements in controlled vibration ensure steady material flow and dosing accuracy, both critical to ensuring the long-term performance of ACE Fiber reinforced asphalt.
The MD3 can also be retrofitted to connect directly into existing asphalt plant controls to allow producers to permanently add the MD3 to the plant’s operational capabilities.
With all the improvements, operators will find the system more user friendly than ever. However, some features needed no improvement. The system can still fit in a cargo trailer, can be set up in minutes, and can still be operated by one person. Moreover, producers can be easily trained and certified to operate the MD3 system if they opt to manage the QA/QC themselves.
Like its predecessor, the MD3 only requires 90psi and 185 CFM of compressed air and 110 volts electric to run, which means it can be easily included in the asphalt mixing process at both batch and drum plant facilities.
The computer interface still tracks cycle weight and time to ensure the accurate dosing of 4.2 ounces of ACE Fiber into each ton of produced asphalt. Data continues to be kept onboard and can be retrieved by USB, or sent via internet if available.
The MD3 continues the excellent tradition of the MD2 — delivering a perfect mix, every time! See video of MD3 in action at http://surface-tech.com/portfolio/ace-fiber-mixing-process/
