旋转式干燥设备的剖析

旋转干燥设备是一个类型的工业烘干设备，减少或^小化它处理通过将它用加热的气体直接接触的材料的水分含量。 Heyl & Patterson，这种类型的机制造，材料，矿产和冶金矿石的化学品和肥料，五谷杂粮，以及纸浆，颜料，生物质能，煤，油砂和土壤修复。

旋转式干燥机的心脏是一个旋转的圆筒，或外壳，稍微倾斜的水平。其长度可以是它的直径的四到十倍。材料被送入气缸的一端，并凭借其旋转和斜率，以及头部的材料的影响，它连续地从另一端的出口。的外壳的内部配备有特别设计的航班，推进到有源区的外壳的原料，并有效地将材料暴露到热源。

该旋转壳在中性或微负压操作，并在每一端固定breechings或端盒是密封的。各种密封结构是用来连接到气缸的breechings，取决于工艺条件。这些变化从简单的布料段，以先进的金属密封。湿进料进入气缸内，通过一个通过其他的breechings并退出。同样地，热空气进入和退出通过breechings。任何静止的下游设备，例如在空气加热器，输送机，空气锁和废气处理设备被密封这些breechings。

重型锻造钢轮胎或骑自行车环安装在外壳上。这些光环支持，因为它的外壳上耳轴辊的旋转和休息。在除了耳轴辊，推力辊有助于保持在其正确的纵向位置的壳。 shell通常于2-6 RPM，使用的齿条和小齿轮或链条和链轮驱动系统旋转。齿条和小齿轮驱动的车型一般采用截齿齿轮的圆周，这是一分为二，以适应安装，并允许齿轮反转，使用寿命长。

Heyl & Patterson转筒干燥器的设计和建造，以客户的要求。因为我们自定义的工程师，回转烘干机，并保持原来的图纸，我们可以根据原来的规格，升级或维修服务的任何机。 Heyl & Patterson提供^的客户支持之前，期间和之后，我们提供的每一个产品的购买。

The Anatomy of a Rotary Dryer

A Rotary Dryer is a type of industrial drying equipment that reduces or minimizes the moisture content of the material it handles by bringing it into direct contact with a heated gas. As manufactured by Heyl & Patterson, this type of dryer is suitable for materials ranging from minerals and metallurgical ores to chemicals and fertilizers to grains and cereals, as well as paper pulp, pigments, biomass, coal, oil sands and soil remediate.

The heart of a Rotary Dryer is a rotating cylinder, or shell, that is slightly inclined to the horizontal. Its length may be four to ten times its diameter. Material is fed into one end of the cylinder and, by virtue of its rotation and slope as well as the head effect of the material, it exits continuously from the other end. The interior of the shell is equipped with specially designed flights that advance the feed material into the active zone of the shell and efficiently expose the material to the heat source.

The rotating shell operates at neutral or slightly negative pressure and is sealed at each end to stationary breechings or end boxes. Various seal configurations are used to connect the breechings to the cylinder, depending on the process conditions. These vary from simple fabric segments to sophisticated metallic seals. Wet feed material enters the cylinder through one of the breechings and exits through the other. Likewise, heated air enters and exits through the breechings. Any stationary downstream equipment such as the air heater, conveyors, air locks and off-gas handling equipment is sealed to these breechings.

Heavy forged steel tires or riding rings are mounted on the shell. These rings support the shell as it rotates and rests on trunnion rolls. In addition to the trunnion rolls, thrust rolls help maintain the shell in its correct longitudinal position. The shell generally rotates at 2-6 RPM using either a rack and pinion or chain and sprocket drive system. Rack and pinion drive models generally utilize a cut-tooth circumferential gear, which is split in two to accommodate mounting and to permit gear reversal for longer life.

Heyl & Patterson Rotary Dryers are designed and built to the customer's requirements. Because we custom engineer each Rotary Dryer and maintain the original drawings, we can service any dryer with upgrades or repairs according to its original specifications. Heyl & Patterson provides superior customer support before, during and after the purchase of every product we supply.
