Abstract
A coiled spring system (20) particularly suited for use in a bowl mill (10) of the type that is employed for purposes of effectuating therewithin the pulverization of material such as coal. It is through the operation of the subject coiled spring system (20) that there is established the magnitude of the forces which the grinding rolls (18) of the bowl mill (10) apply to the coal for purposes of accomplishing the pulverization of the coal. The subject coiled spring system (20) includes stud bearing housing means (36), preload stud means (38) suitably supported from the stud bearing housing means (36), pressure spring means (40) positioned in surrounding relation to the preload means (38), and spring housing means (42) encircling the pressure spring means (40).
