INTAKE AND PRE-CLEANING
Dry stoner type OV 3, OV 7
The dry stoners are used for separation of small stones, glass and metal particles from grain in dry method based on different specific weight of material. They are applied in cleaning sections of flour mills. However, they can also be used for cleaning of other dry, loose and grainy materials. Material is fed onto a inclined screen of the machine moving in vibratory motion. Air exhaust from the machine sub-screen space forms an air cushion and fluid layer above the screen. Due to this phenomenon and the screen inclination, the lighter fraction, i.e. grain, moves down-slope the screen inclination to the delivery end. The heavier fraction, stones etc., coming in touch with the screen cover, are forced by the screen vibration to move up-slope the screen to the outlet for stones. As per the processed material character the grain inlet, aspiration intensity, screen inclination, throw angle setting and vibration amplitude can be adjusted to optimum.
Benefits
- Low electric power consumption
- Minimum of maintenance
- Reliable operation without permanent attendance necessary
- Comfortable visual checking of the machine operation
- Adjustable for different sorts of grain
Description of the machine
The machine stand is welded together from enclosed thin walled steel profiles. The top features an inlet and an aspiration throats. The stand bears the screen suspended on springs and driven by means of a vibrator. The main cover is made as a separate glass laminated shell.
