EDC-3 Standard Automatic Asphalt Digital Electrical Marshall Compactor

For the preparation of Marshall test asphalt mixture specimen, the instrument working process automatic counting, automatic stop. Beautiful appearance, advanced structure, stable and reliable, easy to use.

The digital controlled Marshall electric compactor is suitable for preparing bituminous mix specimens (dia. 101.6mm x 63.5mm) used in Marshall stability testing. The trip mechanism is designed to make the hammer fall at the same distance for every stroke. With some features of digital control, compact times to be preset freely, auto counting and easy to operate etc.

Floor type structure. Composed of mechanical drive and control instrument.The mechanical drive is composed of motor, reducer and chain drive.Single chip microcomputer technology in the electric control cabinet,the control panel with the color LCD touch screen.

The compaction times and stop delay time can be preset by electric control cabinet, the times value can be selected from 0 to 999 times at will. It will do compaction automatically according to preset value. It will stop, cut off power and motor automatically.

Humanized design to move the hammer by hand,It becomes more convenient,safety,effective.Adopting the stationary sample structure of clamping ring,It solves the problem of mold fixing,the mold is difficult to shift and more stable,which gives more convenient and helpful to operators.

The marshall compactor equips a safe control rod. It will ensure the compaction head not lowering down when the mould being installed or taken out.
