Process for polymerising, in a loop reactor, at least one olefin monomer in a liquid diluent to produce a slurry comprising solid particulate olefin polymer and said diluent, wherein the ratio between the actual volumetric solids concentration of the slurry and the maximum possible geometric volume solids concentration of the slurry as measured by the bulk density of an unpacked settled bed of particles, SVCR, is V*0.065 or greater, and the ratio of the cumulative settling distance of an average size particle at any point in the reactor in any direction perpendicular to the direction of the flow, to the internal diameter of the loop reactor, is maintained below [0.084*(V - 6.62) + (0.69 - SVCR)*1.666], where V is the circulation velocity of the slurry in m/s and "cumulative settling distance" is defined as the cumulative distance, expressed as a fraction of the diameter,travelled by a particle in any direction perpendicular to the direction of the flow since the previous upstream pump.
