摘要： A storage bin for handling and discharging plug flow material uses shrouds to prevent wedging of plug flow material such as refuse derived fuel between vertical screws and the end walls of the bin. The bin is divided into two separate sections by the vertical screws. Wedging of plug flow material in both bin sections and material discharge is then stopped. The shrouds force the plug flow material into the active surface area of vertical screws and continuous discharge through an elongated discharge aperture is assured. Two horizontal screws are used to further augment material discharge beneath the elongated discharge aperture. The two horizontal screws are parallel and the bottom of vertical screws are between the two horizontal screws.

摘要： A method and apparatus for manufacturing the screw flight section of a screw conveyor is disclosed. The apparatus includes two horizontal arms which extend from a vertical support and at the terminal end of these arms there are dies for engaging the inner and outer peripheral edges of a flat, sheet metal, annulus-shaped blank with a radial slit. One die is turned on its longitudinal axis while the other remains stationary so that the blank is twisted. After the blank is circumferentially displaced relative to the dies, it is again twisted in the above described manner. This procedure is repeated around the entire circumference of the blank with the result that a helical form is applied to the blank.

摘要： An apparatus and process for recycling scrap film. The apparatus includes a washer-shredder upstream from a film cutter in order to remove impurities from the film. The scrap film is rinsed in a rinse loop which uses screen sieves for removing additional impurities, particularly paper fiber. The apparatus and method substantially reduce conventional problems with the film cutter caused by impurities which customarily are present in unwashed film. The invention is particularly useful for recycling very thin scrap film.

摘要： A continuous cylindrical wood pulp refiner comprising a rotor disposed in a housing having a plurality of structural members. At least one refining plate is mounted to a holder portion of each member such that the entire periphery of the rotor is exposed to refining plates. The pulp to be refined continuously flows axially along the periphery of the rotor. The members define two shells which are pivotally mounted to the refiner base such that the shells may be pivoted away from each other to provide access to the interior surface for changing the refiner plates. Each holder portion has a pair of bores which are parallel to the axis of the rotor. A cam portion of a cam shaft is disposed in each bore. Rotating the cam shaft causes the cam portion to engage the surface of the bore thereby moving the holder portion radially towards or away from the rotor whereby the gap between the refining plates and the rotor can be adjusted. A gear is mounted on an end portion of each cam shaft which extends longitudinally outward through an orifice in the housing. First and second chains engage each gear mounted to the cam shafts which are disposed in the first and second shells, respectively. One of the gears mounted on a cam shaft disposed in the first shell engages one of the gears mounted on a cam shaft disposed in the second shell. A gear motor actuates movement of one of the chains wherein the movement of all of the cam shafts is coordinated to synchronize movement of all of the holders to uniformly adjust the gap.

摘要： The comminution apparatus comprises a drive shaft having a roller bearing which is disposed in a housing. A temperature detector mounted in the housing monitors the temperature of the roller bearing. Hydraulic fluid is supplied to a circumferential groove in the housing to apply hydraulic pressure to the outer raceway. The hydraulic fluid pressure is monitored by a pressure detector and gage and may be vented by a manually operated relief valve. The drive shaft is rotated at normal operating speed and normal load with the bearing clearance at maximum until the bearing reaches an equilibrium temperature. Raising the hydraulic pressure develops a force on the rear surface of the outer raceway, biasing the outer raceway towards the shaft and reducing the bearing clearance. Reducing the bearing clearance reduces waste heat generated by skidding between the rollers and the raceway. When the bearing clearance is reduced to the optimum clearance, the skidding is eliminated and the bearing temperature reaches a minimum value. Further reduction of the bearing clearance imposes a preload on the rollers, increasing the friction between the rollers and the raceways and generating waste heat. The pressure is lowered to the pressure that correlates with the minimum temperature.
摘要翻译：粉碎装置包括驱动轴，该驱动轴具有设置在壳体中的滚子轴承。安装在壳体中的温度检测器监测滚子轴承的温度。液压流体被供应到壳体中的周向槽，以向外滚道施加液压。液压流体压力由压力检测器和量规监测，并且可以由手动安全阀排气。驱动轴在正常运行速度和正常负载下旋转，轴承间隙最大，直到轴承达到平衡温度。提高液压压力在外滚道的后表面产生一个力，将外滚道偏向轴并减小轴承间隙。降低轴承间隙可以减少辊与滚道之间的打滑所产生的浪费。当轴承间隙减小到最佳间隙时，消除了打滑，轴承温度达到最小值。轴承间隙的进一步减小在辊子上施加预载荷，增加滚子和滚道之间的摩擦并产生废热。压力降低到与最低温度相关的压力。

摘要： A hammermill (10) comprises a casing (12) having a longitudinal axis (18) and a sidewall (20) such that an enclosed grinding space (24) is defined within the casing. A rotor assembly (26) is situated within the casing for rotation about the axis, and includes hammer elements each having a radially outer tip (34) which defines a hammer rotation diameter. At least one grinding plate at the inside of the sidewall defines a grinding surface (38) in the grinding space having a radius of curvature centered on the axis, a length dimension parallel to the axis, and a width dimension defined by an arc about the axis. The grinding plate has a plurality of spaced apart edges such that each hammer tip (34) passes along the width dimension of the grinding plate with a clearance from the edges which defines a grinding gap. The sidewall other than at the grinding plate has a non-uniform curvature which defines a non-uniform clearance from the hammer rotation diameter that is greater than the grinding gap clearance. The non-uniform curvature includes at least one sidewall portion having a radius of curvature less than that of the grinding surface.

摘要： A method and apparatus for mixing granular, particulate or pulverant material is disclosed. An unhomogenous mixture of two or more such materials is introduced into and moved through a preferably inclined trough structure having rigid side walls and a flexible floor member. At one or more isolated positions on this floor member it is subjected to relatively intense vibrational motion. It is found that such restricted use of vibrational motion results in a thorough yet gentle mixing of granular, particulate or pulverant materials.
