If an intermittent fault does not reoccur after three consecutive trips, the Malfunction Indicator Light (MIL lamp) will go out but the code will remain in memory. If the fault does not reoccur for for 40 trips, the code will be erased. The only safe way to clear fault codes is to use a scan tool or code reader.

Ball mill - Wikipedia

A ball mill is a type of grinder used to grind, blend and sometimes for mixing of materials for use in mineral dressing processes, paints, pyrotechnics, ceramics, and selective laser sintering.It works on the principle of impact and attrition: size reduction is done by impact as the balls drop from near the top of the shell. A ball mill consists of a hollow cylindrical
