Abstract: An electronically controlled journal loading system 20 for controlling and adjusting the amplitude of the load applied to a journal assembly 19 of a pulverizing mill 10. The journal loading system 20 includes a servomotor 44, resolver 134, vertical gearbox 42, coil spring assembly 40, controller 46 and a user interface 48. The journal loading system 20 provides electronic control and adjustment of the force applied to the journal assembly 19 to thereby increase or decrease the load that a grinding roll 18 imposes on the material being pulverized. In the mode of operation of the servo journal loading system 20, a desired load set point is selected via the user/operator interface 48. The servomotor 44 rotates a preload stud (or servo screw) 50 within the coiled spring assembly 40 in the appropriate direction via the gearbox 42. As the preload stud 50 turns, a bronze nut 100 and bushing 94 move axially along the stud to compress or decompress the spring 86. Based upon the linear movement of the preload stud 50 and the precalculated spring force of the spring 86, the load applied to the journal assembly 19 is displayed on the operator interface 48. Once the journal loading level is achieved the servomotor 44 can be turned off since the spring assembly 40 maintains the selected loading to the journal assembly 19.

Abstract: An apparatus for milling particulate mineral material comprises two cylinders rotatable in opposite directions about parallel axes defining a plane while being yieldingly pressed towards each other, the cylinders defining therebetween a milling compression space having an inlet for the particulate material above the plane and an outlet for the milled material below the plane. To reduce the formation of agglomerates and prevent circumferential and/or lateral flushing of the material, the outlet space is closed by respective lateral flanges at the opposite cylinder end faces and a barrier including a scraping bar extending across the outlet space below the plane into contact with the flanges and having one edge in contact with the peripheral surface of one of the cylinders while an opposite edge defines a milled material output of reduced cross sectional area with the peripheral surface of the other cylinder.

Abstract: The invention relates to a method and to apparatus for the crushing of material to be comminuted by means of a material bed roll mill, in which such material is forcibly delivered in a regulable mass flow to the roll gap. In this way even materials which tend to slip on the rolls can be crushed satisfactorily. It is also possible to keep the nature of the product constant over a wide range of variations in the throughput.
