Our ball mill grinding products apply the ancient principle of ball grinding to the industrial needs of the modern world Many different industries can benefit from the grinding action that these mills offer they are suitable for both dry and wet grinding as well as cryogenic grinding and are commonly used for mixing or grinding chemicals ores paints and ceramic materials
The ball charge of the industrial ball mill was sampled during one of the maintenance stops The mass of balls required to consider the sample representative was too high and it was not possible to achieve the necessary mass The sampling showed many balls with different shapes as shown in the Figure 1
The mill was configured to operate as a RoM ball mill The experiments were conducted at varying mill speeds 75% 85% critical speed feed rate 1200 2800kg/hr and ball loads 15 26% The static mill filling was determined from physical measurements after crash stopping the mill
Grinding ball fragments discharging from ball mills cause extreme wear to downstream processing equipment These ball fragments circulating in a milling circuit will cause excessive wear to sumps pumps hydrocyclones and interconnecting piping Grinding ball fragments contribute very little to the grinding process while consuming power
In ball milling applications the diameter of the balls mill and throw action of the charge provides a low impact environment hence maximum abrasion resistance of steel balls is the desired characteristic CHEMISTRY & HARDNESS High carbon content and high hardness levels affect abrasion resistance in steel balls
Machine will need modifications to fit ball nuts for X axis Drawings for modifications are in the instructions We anodize in Green Black and Clear We have redesigned the kit to use flanged ball nuts We have had to add an up charge for Green anodize Standard Ball screws are rolled 16mm X 5mm pitch with a C7 tolerance / …
