| 20100288862 | PRESSURE MONITOR FOR PULVERIZER - Load cells are placed in the pre-compression systems of spring suspended rollers in coal/ore crusher/classifiers to produce electrical signals representing actual forces generated in the suspension system during crusher operation. This permits forces to be closely monitored during operation and/or automatically adjusted. Alternatively or in addition, alarm signals can be generated when pressures go out of tolerance. | 11-18-2010 |
| 20110101139 | Roll mill with automatic control of roll-to-roll distance and inter-roll pressure - A roll mill for a milling-dispersing treatment has a fixed roll fixed to a frame, and a transfer roll displaceable into and out of contact with the fixed roll in a direction perpendicular to the fixed roll by a servomotor and a ball screw. A laser sensor disposed between the fixed roll and the transfer roll measures the distance between the rolls, and a load sensor measures a pressing force between the rolls. An electronic automatic control device maintains a constant distance and a constant pressing force between the fixed roll and the transfer roll by feedback of detection signals sent from the respective sensors, wherein the servomotor is driven by the electronic automatic control device to adjust the position of the transfer roll. | 05-05-2011 |
| 20120024994 | PRESSURE MONITOR FOR PULVERIZER - Load cells are placed in the pre-compression systems of spring suspended rollers in coal/ore crusher/classifiers to produce electrical signals representing actual forces generated in the suspension system during crusher operation. This permits forces to be closely monitored during operation and/or automatically adjusted. Alternatively or in addition, alarm signals can be generated when pressures go out of tolerance. | 02-02-2012 |
| 20130277470 | BALANCING CYLINDERS - The present invention relates to a roller crusher having two generally parallel rotatable rollers separated by a gap, and a feeding arrangement for feeding material to the rollers. The roller crusher further comprising a base frame and a first and a second roller frame section, each of the first and second roller frames sections being pivotably connected to the base frame and arranged for carrying one of the rollers in bearings arranged at opposed ends of each roller. The roller crusher also comprises at least one balancing cylinder extending between one of the roller frame sections and the base frame such that when the at least one balancing cylinder is activated, the interconnected roller frame sections will pivot relative to the base frame, thus adjusting the position of the rollers relative to the base frame. | 10-24-2013 |
| 20140131490 | COMBINED TANGENTIAL SHEAR HOMOGENIZING AND FLASHING APPARATUS HAVING A NON-UNIFORM ROTOR/STATOR GAP DIMENSION AND A PARAMETER RESPONSIVE TO A VARIABLE ROTOR/STATOR GAP DIMENSION - A combined tangential shear homogenizing and flashing apparatus for destructuring pretreated biomass comprises a housing connectable to a source of pressurized pretreated biomass, and a stator and a rotor mounted within the housing. The stator and rotor being confrontationally disposed and spaced apart by a non-uniformly dimensioned axial gap. The least axial dimension between the rotor and the stator defining a restriction to a biomass flow. In use, rotational movement of the rotor with respect to the stator imparts a tangential shear to a volume of pretreated biomass. The tangential shear homogenizes the volume of pretreated biomass while a pressure difference causes a partial phase separation of the homogenized biomass into vapor and liquid phases such that the pretreated biomass undergoes at least a three-fold total volumetric increase and a weight transition to a vapor of at least one percent (1%). | 05-15-2014 |
| 20160114331 | Impact Crusher and Curtain Adjustment System - An impact crusher for crushing a feed material received through an opening of the crusher is provided. The crusher includes: a housing defining a crushing chamber; at least one elevation adjustable impact barrier mounted in the crushing chamber; a barrier adjustment mechanism configured to adjust an elevation of the at least one impact barrier within the crushing chamber; and a rotor mounted in the crushing chamber and turned by a drive mechanism. The rotor is configured to direct feed material toward the at least one impact barrier. The bather adjustment mechanism includes at least one hydraulic cylinder mounted to the at least one impact barrier. The cylinder includes a sensor for detecting an absolute extension of the cylinder. A system for crushing a crushable material including an impact crusher and controller is also provided herein. | 04-28-2016 |
