摘要： A process and apparatus for the preparation of mortar from an aggregate and a binder is disclosed which comprises the use of a silo provided with at least one partition so as to create in the silo two or more compartments for the separate storage of the aggregate and the binder, the compartments being provided with conveyor screws, the speeds of which can be adjusted to control the volumetric flow of the components to a mixing chamber. A metering valve for water may also be connected to the mixing chamber. The silo compartment for the aggregate may be provided with a heating element to safeguard the mechanically operated slide valve against freezing. The conveyor screw in the outlet for the binder may be provided with a cam and a plunger rod with transverse projections to prevent arching in the compartment for the storage of the binder. The apparatus may be mounted on a truck to facilitate transport to the building site.

摘要： A rotary heating device (20) having reduced NOx emissions including a recirculation system for recirculating gases downstream of a baghouse (12) to the heat source, such as a flame burner (28), and to a quenching ring (40) located at the end of a refractory combustion chamber (32) surrounding the burner flame (30). The addition of the recirculating gas to the burner (28) provides a cooler, turbulent flame (30). The addition of the recirculating gas via the quenching ring (40) to the end of the flame (30) reduces the length and temperature of the flame (30). The cooler, shorter, turbulent flame (30) provides sufficient heat for drying aggregate or for producing asphalt-aggregate mix while decreasing the production of NOx.

摘要： This invention relates to an improved aggregate drying apparatus and method where the dried aggregate is particularly useful for making hot mix asphalt. In accordance with the system, heat typically lost in exhaust gases and moisture evaporated in a heater is recovered to dry and preheat the aggregate. The invention also relates to novel components used in the system, including an improved aggregate dryer (170) and an improved mass flow apparatus (172, 174, 176) for use in an aggregate dryer or otherwise in aggregate feed bins.

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： An apparatus and process is provided for the production of hot mix asphalt (HMA) by the treatment of virgin material alone or adding reclaimed or recycled asphalt pavement (RAP) of up to 100 % of the HMA comprised of reclaimed asphaltic pavement (RAP). The HMA is first heated in either a parallel (10) or a counter flow rotating drum (102) which is supplied with hot combustion gases generated by a remote low NOx burner (11, 104). The temperature of hot gases entering the drum is from about 400 to 2,000 DEG F, and the temperature of gases exiting from the drum is from about 130 to 220 DEG F. The HMA material optionally can be subjected to microwave radiation (29) to raise the material to a final temperature, or optionally to only reorient the dipolar molecules of the material without any measurable heating of the material. The exhaust gas is treated and made environmentally safe. The hot gases exiting from the drum are passed through a knockout box and then through a baghouse (40) having acrylic bags coated with a protective layer of particulate material. The gases exiting the baghouse (40) are passed through an oxidizer to further remove smoke and asphaltic material and at least a portion of the gases from the oxidizer are recycled through a heat exchanger.
摘要翻译：提供了一种设备和方法，用于通过单独处理原始材料或添加高达100％的由再生沥青路面（RAP）组成的HMA的回收沥青路面（RAP）来生产热拌沥青（HMA）。 HMA首先在平行（10）或逆流旋转鼓（102）中加热，该鼓被提供有由远程低NOx燃烧器（11,104）产生的热燃烧气体。进入滚筒的热气体的温度为约400至2000°F，从滚筒离开的气体的温度为约130至220°F。HMA材料任选地可以进行微波辐射（29）以提高该材料达到最终温度，或任选地仅重新取向材料的偶极子分子，而无需任何可测量的材料加热。废气被处理并使其对环境无害。从滚筒离开的热气体通过敲除箱，然后通过具有涂覆有颗粒材料保护层的丙烯酸袋的袋室（40）。离开袋室（40）的气体通过氧化剂以进一步除去烟气和沥青材料，并且来自氧化剂的至少一部分气体通过热交换器再循环。
