Ball Mill Duration

Aball millcan be installed on top of the concrete base when its compressive strength is up to more than 75 before installation check the quality of the basis to ensure that concrete is not affected by the strength of the defect the number and position of the reserved hole meets the requirements and the reserved holes have no water
