Circulating oil lubricates the bearings. The driven shaft is lifted due to oil pressure so the load on the bearings reduces. The heat generated in the bearings is reduced. The heat generated in the bearing is taken by Oil. Oil is cooled in a heat exchanger cooling system by circulating water. Water is cooled in a radiator with air circulating fan.

In this case, the increased circulating load counteracts the tendency of the Barmacs to create more fines than the roller crushers.

In a woodchip/sawdust to pellets converting mill there is a machine for that pelleting. Design prohibit any larger bearing and the bearings last 800 to at best 1000 hours before worn out, not failed but interfering with the work of the machine due to clearance increase. It is supposedly about normal but not that good IMHO. Can a circulating oil system with cooling improve do …

Increasing the circulating load to 500% brings that value up to 2.6 times, for a further relative productivity increase of 30% (2.6/2.0 =1.30). And all this is achieved with the same ball mill power! The most efficient ball milling circuits require a high circulating load ratio.

How Much Circulating Load. In designing a closed-circuit crushing stage, the question of how much circulating load should be carried is a very important one. It not only has a direct bearing upon the capacity of the stage; it determines the amount of screening surface, and the elevating capacity necessary to handle the load in the circuit.
