Jul 15 2000018332In unattended cutting EDM is the easier process to automate because its more predictable than milling In a process that uses robots for loading electrodes and workpieces a complete EDM process including electrode production can run around the clock effectively with minimal human attention For high expertise parts.
This process can be carried out in batches or it can be continuous Continuous ball milling involves the ongoing automatic loading of materials to be crushed and unloading of crushed materials Depending on the scale of the milling operation ball mills can be small enough to fit on work benches or large enough to take up entire rooms.
Ball Mill for Cement Grinding Process Cement ball mill structure when ball mill is working raw material enters the mill cylinder through the hollow shaft of the feed the inside of the cylinder is filled with grinding media of various diameters steel balls steel segments etc when the cylinder rotates around the horizontal axis at a certain speed under the action of centrifugal force and.
However if the material has a very low viscosity ball milling is a better dispersing process than using a high shear mixing vertical system Since organic pigments are more difficult to break down to their primary particles compared to inorganic pigments ball milling is the recommended choice.
