The blast media in your shot blast machine is provided as a "working mix” to achieve your required process. After a period of blast time it will not perform to the required standard as it has now reduced in size. If it remains in your machine, you can expect to increase the wear and degradation of the blast wheel components together with the recovery system of your machine. It will increase production times and power consumption because of the longer blast duration required. An efficient separator will remove unwanted contaminants and undersized media without carrying out good, usable abrasive. It is vital you regularly check the efficiency of your separator and the size at which media, fines and dust are being removed.
