Several Key Features of the Asphalt Mixture Stability Tester
An automatic digital-display high-strength Marshall stability and flow value testing apparatus, characterized in that it comprises a digital-display pressure testing machine, two Marshall test molds, shims, a flow value sensor, and a signal switch. Specifically, the two Marshall test molds are installed directly above the center of gravity of the lower platen of the digital-display pressure testing machine and below the upper platen of the same machine. The two Marshall test molds are fitted together vertically to form a cylindrical cavity, and the flow value sensor is positioned on top of the Marshall test mold. The flow value sensor, the digital display screen of the digital-display pressure testing machine, and the hydraulic sensor are each connected to the signal switch. A shim is placed between the upper Marshall test mold and the upper platen of the digital-display pressure testing machine.

Working Principle of a Pouring-Type Asphalt Mixing Plant
After the pouring-type asphalt mixture mixer is powered on, the main mixing motor is started via a start/stop switch equipped with maintenance functions. Once the equipment has entered its normal operating state, the amorphous refractory material or the object to be mixed can then be added into the mixer’s mixing bowl.
