SHY-I实验室回转窑适用于冶金、地质、矿山、化工、建材等部门。对物样进行焙烧烧结试验。和传统的马沸炉，管式炉相比，它的****优点在于炉管是转动的，物样在加工过程中，不停地翻动，因此加工质量好，效率高，并且取得的实验数据较接近于生产状态。由于回转窑可以连续进出料，所以加工大量物样时，更能显示其优越性。同时，该产品也能应用于半工业性生产。另外旋转炉管的两端采取了密封措施，所以在使用过程中还可以通入氧化，还原等必要的气体。本产品由原地矿部唯一指定企业生产，执行行业标准。

实验室回转窑分两部分：第一部分是窑体；第二部分是电器控制箱。窑体部分又分为电炉炉体和动力转动两部分，炉体部分采用粘土质圆形炉膛，沿圆轴向均匀插9根硅碳棒（每三根串联成一组，三组按“Y”接线）高铝质的陶瓷炉管又置于硅碳棒内周，通电后硅碳棒产生高温，加热炉管。

SHY-I Laboratory Rotary Kiln is applicable for tests of calcination and sintering of samples in metallurgical,geological, mine, chemical, building material and other industries. Compared with the traditional muffle furnace and tube furnace, the most important advantage of the kiln is that the furnace tube is rotating. In the processing of materials, the furnace tube keeps rotating with the resultant good quality and high efficiency of the processing and the test data obtained relatively similar to the production state. Given continuous material charging and discharging for the rotary kiln, processing of massive materials can more display its advantages. It also can be employed in pilot plant production . In addition, the rotary kiln tube is sealed off at its both ends and therefore, gases necessary for oxidation and reduction can be sent into it during operation . The product is made by the only manufacturer designated by the former Ministry of Geology and Mineral Resources, in compliance with the Industrial standards.

Laboratory Rotary Kiln consists of two parts: part one kiln body; part two electric control box. The kiln body is divided into two sections of electrical furnace body and dynamic rotation with the kiln body constructed of clayed circular hearth uniformly inserted with 9 silicon carbon rods along the circular axis( one group made up of 3 rods and Y connection for every 3 groups). High aluminum ceramic furnace tube is installed in the silicon carbon rod. After being energized, the silicon carbon rod will generate high temperature to heat the furnace tube.

III. Structure and Working Principle

        实验室回转窑分两部分：第一部分是窑体；第二部分是电器控制箱。窑体部分又分为电炉炉体和动力转动两部分，炉体部分采用粘土质园形炉膛，沿园周轴向均匀插9根硅碳棒（每三根串联成一组，三组按“Y”接线）高铝质的陶瓷炉管又置于硅碳棒内周，通电后硅碳棒产生高温，加热炉管。

Laboratory rotary  kiln is composed of two parts, namely kiln body and electrical control cabinet.  Kiln body is composed of electric furnace body and rotating part. The furnace  is provided with a round hearth made of clay. Nine silicon  carbide rods are inserted evenly in axial direction around the  circle (three connected in series compose one group, and the three groups are  connected through Y-shaped connection). Around the inner circle of silicon carbide rod are high-aluminum ceramic  furnace tubes which are heated by silicon carbide rod after the power supply is  connected.

动力部分采用一台0.6KW 的调速电机，通过减速箱，带动传动轴，又经过链条带动炉管旋转。加料器和传动轴间设置了一个三档变速器，使给料量增加了调节的余地。电机和减速箱设置在炉体下面，整体较为紧凑。

Power part is  provided with a 0.6KW speed regulating motor that drives the transmission shaft  through reduction gearbox, and then it drives the furnace tube to rotate  through chains. A three-shift transmission is mounted between feeder and  transmission shaft, enabling the feeding amount to be adjustable. The motor and  reduction gearbox are under furnace body, and the overall structure is  relatively compact.

整个回转窑的电器部分，集中在控制箱内，由炉子上热电偶测得的电讯号进入控制箱，通过它可以实现温度调节和自动控制，调速电机也由控制箱上的仪表实行无级调速。

Electrical parts of the  whole rotary kiln are concentrated in control cabinet. The electric signal  detected by thermocouple of furnace gets into control cabinet and performs  temperature regulation and automatic control. The speed regulating motor  performs stepless speed regulation through the instrument on control cabinet.
