    • A novel, high-temperature heating, axially rotatable heating drum is designed to be mobile on wheels and lighter than before. Thermal economy in the apparatus is better than in the past by virtue of a mirror-like inner drum surface made of nickel-chromium-steel. The drum wall reflects rather well radiation heat back to the heating space and conducts heat much better than the traditional firebrick lining. This enables cooling by the material to be heatedwhen the material is still cold. At the same time the material is pre-heated by conduction of heat without actual energy consumption. Due to reduced weight of the drum, the speed of rotation can be substantially increased. The combustion air can be used initially as a heat insulator. Heating temperatures can be raised by virtue of the drum being refractory. As a cooling medium can also be used water, combustion air, or some other readily available cooling agent. The heated product can be separated by means of a vortex in a variety of fractions on the basis of a grain size or density. The swelled end product can be used for example for making a ceramic road or foundations. The ceramic expanded product can be useful heat insulation for a wide range of applications. Being lighter than water, the ceramic product can be designed as a floating bridge or as a floating foundation for a house. The heatingtemperature higher than before enables disposal of wastes and toxins and practical reuse of wastes. The rustproof, non-corrodible drum can be used to solve many chemical problems at different fields of technique.
    • 一种新颖的高温加热轴向可旋转加热鼓设计成可以在轮子上移动,比以前更轻。 凭借由镍铬钢制成的镜面状的内鼓表面,该装置的热经济性比以往更好。 鼓壁将辐射热量反射回加热空间,并且比传统耐火砖衬里更好地传导热量。 当材料仍然冷时,可以通过被加热材料进行冷却。 同时,材料通过传热而预热,而没有实际的能量消耗。 由于滚筒的重量减轻,可以显着提高旋转速度。 燃烧空气最初可以用作隔热材料。 加热温度可通过滚筒难以提高。 作为冷却介质也可以使用水,燃烧空气或其他一些容易获得的冷却剂。 基于晶粒尺寸或密度,加热的产物可以通过各种馏分的涡流分离。 膨胀的最终产品可用于制造陶瓷路或地基。 陶瓷膨胀产品可用于广泛应用的有用的隔热。 比水轻,陶瓷产品可以设计成一个浮桥或一个房子的浮动基础。 比以前更高的加热温度可以处理废物和毒素以及废弃物的实际再利用。 防锈,不腐蚀的鼓可用于解决不同技术领域的许多化学问题。
