Improving Efficiencies in a Frac Sand Plant
Situation: A frac sand producer contacted Met Pro about how they could size frac sand more efficiently. Their set up included a multi-deck vibrating screen with having everything that passed through the bottom deck reporting to a classifying tank. The tank would classify the sand, but not sharply and with a lot of waste. The outcome was that a lot of sand was wasted and that the material that was to be dried contained a lot of fines (clay). This clay caused issues with the drier and was a major contributor to screen plugging.
Solution: After reviewing the plant and visiting with the customer, we suggested the Met Pro Yield Pro RCS70, which was subsequently installed. The Yield Pro was purchased and installed. The screen underflow was then pumped through a Met Pro Stack Pro dewatering cyclone for thickening and primary declay purposes. The underflow of the Stack Pro fed the Yield Pro separator where rising current water and a teetered bed made the necessary cut point.
Result: The outcome was a clean, very near-sized product that the customer could feed to their dry plant. Waste was virtually eliminated and production increased.
