摘要： A drum-type wood chipper for processing wood includes a chipper drum that is adapted to rotate about a generally horizontal drum axis, a plurality of cutting blades that are disposed around the periphery of the chipper drum, and an engine that is adapted to rotate the chipper drum about the drum axis. The wood chipper also includes a feed system that is adapted to advance wood to be processed towards the chipper drum, and a controller that is operatively connected to the engine and adapted to determine an instantaneous engine operating rate during rotation of the chipper drum. The controller is also operatively connected to the feed system and adapted to control the rate of advance of wood towards the chipper drum. The controller is also adapted to modify the rate of advance of wood towards the chipper drum as the instantaneous engine operating rate changes while the chipper drum is being rotated.

摘要： A paving machine (110, 210) discharges HMA or other paving materials directly on top of a distributing auger (130, 230) located between a paving material storage hopper (116, 216) and the screed (138, 238). The distributing auger (130, 230) is then capable of remixing any partially segregated paving materials and of uniformly distributing the paving materials directly adjacent a previously-paved segment. Materials may be discharged on top of the distributing auger (130) from a discharge opening (150) of a gravity feed hopper (116) located adjacent the distributing auger (130) or from an inclined conveyor (300, 302) delivering materials from a more standard hopper (216) mounted near the front end of the paving machine (210).

摘要： A hot mix asphalt plant has a catalytic reactor (16) which can effectively and reliably reduce VOC and NOx emissions produced during plant operation. The reactor effectiveness is enhanced by exhausting the gas stream from a primary dryer (12) of the plant at a sufficiently high temperature for effective catalytic reaction. Since withdrawal of gases from the dryer at these elevated temperatures necessarily reduces the effectiveness of the dryer, overall plant efficiency is maintained by using the treated gas stream from the catalytic reactor to heat further the aggregate in a secondary dryer (14), which is preferably a finishing dryer such as fixed sleeve dryer drum coater. Poisoning of the catalyst is avoided by removing at least a large portion of the dust in the gas stream via a high efficiency cyclone (18) prior to introducing the gas stream into the catalytic reactor. Gas exiting the secondary dryer may be further treated in baghouse assembly (22). Ammonia (20) or urea may if desired also be injected into the gas stream prior to its introduction into the catalytic reactor.
摘要翻译：热拌沥青设备具有催化反应器（16），可有效且可靠地降低工厂运行过程中产生的VOC和NOx排放。通过在足够高的温度下将来自设备的主干燥器（12）的气流排出以进行有效的催化反应来增强反应器的有效性。由于在这些升高的温度下从干燥器中取出气体必然会降低干燥器的有效性，所以通过使用来自催化反应器的经处理的气流来进一步在二次干燥器（14）中进一步加热聚集体来维持整个设备的效率，一种整理干燥机，如固定套筒干燥机滚筒式涂布机。在将气流引入催化反应器之前，通过高效旋风分离器（18）除去气流中的至少大部分灰尘来避免催化剂的中毒。离开二次干燥器的气体可以在袋式排气装置（22）中进一步处理。如果需要，氨（20）或脲可以在引入催化反应器之前注入到气流中。

摘要： A rotary drum dryer (12) has devices for cooling shielding flights (44) located in the combustion zone of the drum. The devices comprise cooling flights (46) which rotate with the drum to scoop up relatively small amounts of virgin aggregate from aggregate accumulated in the lower portion of the drum and to shower this aggregate over the outer radial surface of the shielding flights (44) upon further rotation of the drum, thereby cooling the shielding flights without substantially decreasing the mean temperature of the aggregate. Cooling efficiency is enhanced by the continuous cascading of fresh aggregate over the shielding flights from the cooling flights (46) through a substantial portion of the drum's rotation. The cooling flights and shielding flights preferably cooperate to limit or even prevent the showering of materials into the burner flame (24) and thus inhibit burner flame quenching and accompanying emissions. Particularly preferred cooling flights take the form of auxiliary flights which can be easily adapted to existing shielding flight designs.
摘要翻译：旋转滚筒式干燥器（12）具有用于冷却位于滚筒的燃烧区域中的屏蔽层（44）的装置。这些装置包括与滚筒一起旋转的冷却翼片（46），以从聚集在滚筒下部的骨料中汲取相对少量的原始骨料，并将该聚集体淋浴在屏蔽薄片（44）的外径向表面上鼓的进一步旋转，从而冷却屏蔽飞行而基本上不降低聚集体的平均温度。通过连续级联新鲜骨料，通过滚筒旋转的大部分，从冷却翼片（46）穿过的屏蔽翼片连续级联，从而提高冷却效率。冷却翼和屏蔽翼优选地配合以限制或甚至防止材料进入燃烧器火焰（24）中并因此阻止燃烧器火焰熄灭和伴随的排放。特别优选的冷却飞行采取辅助飞行的形式，其可以容易地适应现有的屏蔽飞行设计。

摘要： A drum mixer (10) is disclosed which is useful in the continuous production of asphalt paving composition, and which has provision for the accurate control of the final temperature of the composition being produced. The drum mixer (10) comprises a fixedly mounted cylindrical sleeve (32) disposed in a generally horizontal orientation, and rotating blades (42) for conveying the heated aggregate longitudinally through the interior of the sleeve (32). An opening (54) is provided in the side wall portion of the sleeve (32), and a box-like enclosure (55) covers the opening (54) and mounts a plurality of sensor mounting tubes (64), so as to permit one or more sensors (66) to be positioned at a location within the enclosure (55). The enclosure is located where the blades (42) or mixing action in the sleeve (32) will supply a regular flow of the aggregate into the enclosure (55), and so that the aggregate then slides over the sensors (66). The sensors (66) are thus subjected to a representative portion of the aggregate, and they are protected from both the radiant heat of the burner (27) and the physical abuse of the mixing action.

摘要： An apparatus (10) is disclosed for the cold, in-place recycling of asphalt paving of an asphalt roadway. The apparatus (10) is self-propelled, and it includes a cylindrical milling drum (32) mounted at a medial location along its longitudinal length and which serves to remove a thickness of the asphalt paving and break the same into particles as the apparatus (10) moves forwardly along the roadway. The particles are lifted (42) to a separating screen (45) which is positioned forwardly of the drum (32), and the particles are thereby separated into a first portion of relatively small particles suitable for recycling and a second portion of oversized particles. The first portion is delivered to the rear end (14) of the apparatus (10) where it is mixed with a suitable liquid additive, and then discharged onto the roadway. A following paver then forms the discharged material into new paving. The second portion of oversized particles is discharged onto the roadway at a location in front of the milling drum (32). Thus the milling drum (32) again contacts the second portion upon forward movement of the apparatus (10), and the drum (32) acts to further crush the particles and cause them to be recycled through the apparatus (10).

The grinding machine includes a grinding cylinder that is adapted to rotate about a generally horizontal grinding axis and a feed roller assembly that is mounted on the frame at the rear end of the feed hopper and in front of the grinding cylinder. The feed roller assembly includes a feed roller that is adapted to rotate about a generally horizontal axis in a first direction that urges the material towards the grinding cylinder and a second direction that urges the material away from the grinding cylinder. A controller is operatively connected to the feed roller and to the feed conveyor and is adapted to control the rotational speed of the feed roller and the speed of the feed conveyor to obtain a predetermined ratio of feed roller rotational speed to feed conveyor speed.
