摘要
螺旋运输机是一种连续的物料运输机机械，通过电动机作为动力源带动螺旋轴转动进而带动螺旋叶片的旋转，使物料槽内的物料沿物料槽做轴向的移动，因为物料的自身重力，排出卸料口。
随着现代运输物料的种类增多，运输成本也在逐渐的增加，合理的设计选择螺旋运输机也变得至关重要，首先要了解螺旋运输机的工作原理；其次根据要运输物料的种类、运输要求、工作环境等选择要设计的螺旋运输机。此次要运输的物料时干燥的煤粉，根据运输量和运输距离计算输出功率，接下来根据功率选型减速机、电动机来解决当前的问题。

 Abstract

Screw conveyer is a kind of continuous material conveyor machinery, through the motor as power to drive the rotation of the screw axis rotation to drive the spiral blade, make the material slot materials along the material tank do axial movement, because the material of its own gravity, the discharging mouth eduction.
With modern transportation material increase in the number of species, transportation costs are also gradually increased, the reasonable design of screw conveyer has become very important, must first understand the working principle of screw conveyer; Secondly, according to the types of transportation materials, transportation requirements, working environment, and so on, the design of screw conveyor. The transporting materials dry pulverized coal, according to the traffic and transport distance calculation power output, then according to the selection of reducer, motor to solve the current problem.
