1. Sand Preparation System Sand Formula: Quartz sand (AFS 50-60) 85% + bentonite 8% + coal dust 5% + water 2%. Mixing time: 4-6 minutes. Compactness: 85-90 units. - Sand Reclamation: Vibratory screening + magnetic separation + baking (750°C) achieves ≥90% sand reuse rate. New sand replenishment ≤5%.
Material:Grey iron,Ductile iron Order:OEM according customers'drawings Castings:sand casting Fittings have sufficient sweep to allow free, unobstructed flow. They are made with a shoulder that is the same diameter as the inside diameter of the pipe. Therefore, when the pipe is threaded onto the shoulder, a continuous passage is created, leaving no place for solid matter to collect and clog the pipe.
