70mm Grinding Ball Casting Mold

Grinding Ball Casting MoldGrinding Steel Ball Mold is used to the shock chilling forming technology to produce steel grinding balls from diameter 40mm to 150mm. In normal operation, the steel grinding ball mold can be used for 4000 times.  The Main Specification Of Grinding Ball Casting Mold Ball Piece/ MoldMouldBall Piece / MoldModels4 balls50mm10 Balls15mm60mm20mm70mm8 Balls25mm80mm30mm90mm40mm100mm6 Balls50mm110mm60mm120mm3 Balls140mm130mm150mm   The Advantage Of Grinding Ball Casting MoldGrinding media ball metal mould is very easy to operate. The same size top grinding ball mold and bottom grinding ball mold are interchangeable. If the ball core is worn,using a new ball core, then it can continue be used thousand of times.Low cost and high efficiency. The average utilization rate of molten metal liquid is over 75%. High yield and long service life. Producing 1 ton grinding ball just needs 1.2-1.5usd mold cost.Grinding media metal mold adopts chill forming technology which makes grinding balls' inner structure more refined and closer. Then surface hardness and inner hardness of grinding ball are almost the same. The grinding balls have better wear resistance./* March 10, 2023 17:59:20 */!function(){function s(e,r){var a,o={};try{e&&e.split(",").forEach(function(e,t){e&&(a=e.match(/(.*?):(.*)$/))&&1
