KWS replaced the shaftless spiral and torque tube with heavy duty shaftless flighting, a stronger torque tube, and full penetration continuous welds on both sides of the flighting. A section of bare pipe was intentionally left for product to discharge. The key to solving the plugging issue was the addition of left-handed reversing flighting. Raw material flowing past the bare pipe section was now introduced to the left-handed flight which was mechanically sharpened by KWS to slice the raw material off, allowing it to fall through the discharge 100-percent of the time. Knowledge and experience provided by KWS is second to none, creating a very cost-effective solution resulting in 100-percent customer satisfaction.
