Abstract
Methods and apparatuses for forming pellets, such as potash pellets, for example, are provided. The methods involve feeding agglomerate granules on to the operative surface of an assembly of rollers. The rollers are aligned to have parallel central rotational axes and there is a longitudinal gap between adjacent rollers. In order to form the pellets, the rollers are rotated to agitate and abrade the agglomerate granules on the operative surface of the assembly of rollers and form pellets.
Claims44
A method of forming a plurality of pellets from a plurality of agglomerate granules, comprising the steps of:
- (a) feeding the plurality of agglomerate granules on to an operative surface of an assembly of rollers, the rollers having been aligned to have parallel central rotational axes and spaced apart from one another so that there is a longitudinal gap between adjacent rollers, wherein the width of the longitudinal gap is smaller than a size of the pellets;
- (b) rotating the rollers to agitate and abrade the agglomerate granules on the exterior operative surface of the assembly of rollers and form substantially rounded pellets;
- and
- (c) discharging the pellets from the rollers.
