I'm in the process of screening cow sand for a customer who requires it to be screened to a 2 millimeter size. I am using a Powerscreen Mark 2 with a 4x6 screen box and a 2 millimeter harp screen (.667 wire). However, I am facing an issue with clay particles in the sand sticking to the screen wire and causing blockages, resulting in a slow production rate of only 10 yards per hour. The sand is slightly damp, but not excessively wet. I am wondering if there are any solutions to this problem, or if I should wait for the sand to dry completely before attempting to screen it again. Last summer, I had success screening with a 3 millimeter screen, but it seems that this particular customer's cows require a finer screening process.
While I understand this may not be immediately helpful, I specialize in screening 1mm USGA approved golf course sand. The optimal temperature for this process is 16 degrees above zero. In the meantime, consider loading out the top dry material and rotating where you collect the material to allow the sun to dry the next batch before depositing it at the plant. I invested in a custom end tension screen from Major Wire specifically for handling this fine material, although it was a bit pricey at $2500 for a 4x8 deck. Sincerely, Grandpa.
Answer: - Clay particles in the sand are sticking to the screen wire, leading to blockages and slowing down production.
Answer: - The Powerscreen Mark 2 with a 4x6 screen box and a 2 millimeter harp screen (.667 wire) are being used for the screening process.
Answer: - The current production rate is only 10 yards per hour due to clay blockages caused by the sand sticking to the screen wire.
Answer: - It is a consideration to wait for the sand to dry completely before screening it again to potentially reduce blockages caused by clay particles.
