Extec Robotrack

Extec Robotrac is a roughing of inert with a compact design that makes it extremely maneuverable in tight areas.
The Robotrac vibrator sieve mainly lends in quarries and demolition companies. The roughing consists in the separation of aggregate of large size from that of smaller dimensions. The loaded material is initially prevagliato with a vibratory grill bar. The bars have initial aperture of 95mm and 130mm end, that, in order to reduce clogging. The materials which will be passed through the pre-screening grid will be screened by a second vibratory grid typically 80mm. In the 'use of finer if moistened materials can clog the screening grid, therefore, the angle of the grid is set to 25 degrees for coarse materials, while if the material is less than 6mm the grid must have an angle greater than 30 degrees.
