* The function of the primary cleaner is to”scalp“ the belt of the coarse carry back materials which would otherwise overload the secondary and tertiary cleaners. | |||
* In terms of volume, the primary cleaner is responsible for the removal of up to 75% of the total carry back and is an essential part of the system. It has the added advantage of placing the carry back directly into the flow of material. | |||
* The course materials do not cause a problem of carry back. This is normally because of the fine and sticky particles in the mix of material. | |||
* These fine and sticky particles are removed by the secondary and tertiary cleaners. | |||
