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.
