G-125 Charlotte Fully Programmable Automatic Asphalt Emulsion Plant

This System is mechanically and electronically complete. It is constructed of the highest quality materials and design. Components such as valves, strainers, flow meters, temperature sensors, and pressure sensors, are of highest quality construction. All components mentioned including pumps, are fully automated. All components can be monitored and controlled by VFDS, which allows for ease of programming for formulation and system control and monitoring.

The Asphalt flow meter is the most accurate type available.

The whole system is PLC controlled. Auto start and auto finish.

Production of 24 to 40 tons per hour of very high-quality asphalt emulsions and related products.

For: Quality Road Paving Grade Water Emulsified Asphalt

Both industrial emulsions and road paving grades are produced on our equipment. The rapid shift to modified emulsions has required many producers to look to the Charlotte Colloid Mills because of their ability to handle high viscosity emulsions while supplying a consistently high-quality product.

If you require corrosion resistant processing, we offer Charlotte Asphalt Mills with the rotor and stator fabricated from type 316 stainless steel. The entire product processing area can also be fabricated totally from type 316 stainless steel. This option is incorporated upon request. Typically, everyone chooses stainless steel rotors and stators for asphalt. Stainless is very good for corrosion resistance and can be reworked later. Hardened steel is the other option and is typically only used when clay or sand is put into the emulsion.

All Charlotte Colloid Mills are designed to process materials up to 400°F and withstand product throughput pressures up to 150 PSI. All Charlotte Mills have externally adjustable rotor and stator gap clearances. These clearances can be set anywhere from .005” to .070”. Settings are achieved in increments of .001”. For processing versatility, Charlottes are fully jacketed to permit product heating via low pressure steam or oil during operation. Our equipment can offer you production capacities that range from one to ten thousand gallons per hour equal to up to forty tons per hour.
