GreyStone’s automated log washer saves sand/aggregate producers time and money by increasing efficiency and lowering labor costs while keeping the quality of sand/aggregate consistent. It’s very important for log washer operators to keep output quality consistent when washing their product without having to make frequent manual adjustments to the angle of inclination that lower production. GreyStone’s automated log washer is manufactured with a hydraulic support system tied to a PLC sensor that detects the tonnage going through the unit. When the tonnage decreases, the system detects this and increases the angle of inclination—also increasing the material retention time in the unit—until the sensor detects the proper tonnage. If tonnage increases, the hydraulic system automatically decreases the angle of inclination, which decreases material retention, until the proper tonnage is detected. Upper and lower limit switches are employed to prevent excess inclination or damage to the unit. 
When the feed rate changes, the automated log washer automatically adjusts to the appropriate angle of inclination.

More About GreyStone’s Automated Log Washer… - Removes tough plastic clays from coarse sand/aggregate by scrubbing it with paddles
- Breaks down clay and liquefies it by causing rock to grind against rock
- Typically operates at inclinations between 5 and 10.5 degrees
- As the angle of inclination increases, output capacity of the unit decreases, with a corresponding increase in retention time
- Decreasing the angle has the opposite effect: increased capacity and a decrease in retention time
- Removes the need for human input beyond an initial calibration by the operator, eliminating costly trial-and-error methods
- Increases efficiency, while reducing labor costs
- Adjusts to inconsistent feed rates so producers increase spec material output
