The invention relates to a piston system () for use in a homogenizer, comprising a piston () that is configured and arranged to make a reciprocating movement in use of the piston system, a cylinder () that is configured and arranged to receive and guide at least a first part of the piston, a first supply channel () that is configured and arranged to supply a lubricating medium () to a portion () of the first part of the piston that in use is arranged inside the cylinder, and a second supply channel () that is configured and arranged to, in use, supply a cooling medium () to a second part of the piston outside the cylinder. Also disclosed is a process for the production of an elastomer agglomerate composition forcing a slurry comprising elastomeric particles through an aperture to obtain the elastomer agglomerate composition using the piston system.
