Processed Grinding Rollers | 1-ton Grinding Roller Casting Factory | Custom Large Grinding Rollers

Xinxiang Great Wall boasts a professional casting workshop equipped with large, advanced smelting furnaces and machine processing equipment. We specialize in manufacturing various specifications of vertical mill grinding rolls and roller sleeves, offering high wear resistance and long service life.

Vertical Grinding Mill Grinding RollerThe main component for material crushing and grinding, consisting of roller shafts, hubs, roller sleeves, pressure rings, bearings, and sealing components. The number of grinding rollers in a vertical mill varies mainly due to different production capacities.3-6 rollers, each mounted on the same shaft and rotating at different speeds, achieving an excellent grinding effect.

Process Flow

Xinxiang Great WallOptimized design of mill rolls with chemical matching, utilizing advanced water glass sand molding technology to overcome the shortcomings of past structures, preventing breakage during roller loading, with the process being:

Xinxiang Great WallBased on customer requirements, select the appropriate wood mold for shaping design, and use Huazhu casting before pouring.CAE casting simulation, strictly following the process of wood mold – molding – smelting casting – insulation – sand removal – heat treatment – rough and fine machining – packaging and shipment, to cast high-quality roller castings.
