rod grinding mills for c 33 sand prodcution The continuous ball and pebble mill grinding units range from quot mm diameter to quot mm diameter and from quot mm long to quot m long pattersons unmatched ball and pebble mill custom design experience and manufacturing capability is your assurance of a system that meets your requirement for maximum grinding efficiency...

In addition the surface area per unit volume of the steel bar medium is smaller than that of the steel ball medium so the utilization coefficient of the rod mill is lower than that of the same simplified diameter ball mill and it is not suitable for fine grinding equipment...

Rod mills are less common than ball mills for grinding minerals The rods used in the mill usually a high-carbon steel can vary in both the length and the diameter However the smaller the rods the larger is the total surface area and hence the greater the grinding efficiency...

The grinding rods contact the material being ground along the line but not in separate points as is the case in ball grinding process Besides coarse particle of the material being ground in the rod mills protect fine particles against smashing which results in a more homogeneous product...

Effect of Ball Size and Properties on Mill Grinding Capacity Current ball milling theory suggests that grinding capacity is influenced by the size of balls charged to the mill In selecting the appropriate ball charge the first objective is to determine that ball size which will grind the coarse particles most efficiently This size should be the largest ball size charged to the mill The...

Grinding media shape is very important for grinding performance most of the researches conclude that balls are better than con Cylindrical grinding media also known as grinding cylpebs have long been replaced by smaller spherical grinding media like forged steel ball as they have been found to be more efficientOne of the most important variables is the surface area or string generated by...

Rod mill is one kind of grinding mills where steel rods are used as grinding medium The rod mill usually gives a reduction ratio in the range 15-20 1 On the other hand steel or ceramic balls are used as grinding medium for ball mill Since the balls have much greater surface area and contact points than rods they give relatively finer...

Cylpebs of equal diameter and length have 145 greater surface area than balls of the same mass and 9 higher bulk density than steel balls or 12 higher than cast balls As a result for a given charge volume about 25 more grinding media surface area is available for size reduction when charged with Cylpebs but the mill would also draw...
