SD-20A Series Electric Program-controlled Screw Press --The Automatic Refractoryforming equipment FEATURES: This new structure is based on the refractory forming characters, which is our company developped through SD20 Series for the refractory automatic feeding and rejecting bricks, and it will make the reality of refractory automatic production. THE ADVANTAGES OF THE PRESS: 1. Automatic in high level, the feeding, forming and brick-rejecting can be controlled automatically; 2. Correctly control the impact power, highly precised product; 3. can reject two bricks one time; 4. Well lubricate, the screw is sealed in the spindle, reduce the dust pollution. The nut and screw are sunk in the oil pool, which improve the life of screw and nut; 5. High efficient and energy saving, it can save 40%--50% energy comparing to the Friction Press; 6. Hydrantly rejecting, rejecting height can be set freely, and the injecting power is stable.
