Screw conveyor motor power tilt angle and the impact on transport efficiency

Screw conveyor is a continuous material handling machinery , due to the continuous conveyor working principle , structural features , the direction of transport of materials and

methods and a range of other special characters are different, so variety. In the screw conveyor design, delivery of materials is mainly based on the ratio of

Heavy transport most , transmission distance, transmission angle , and other parameters to determine the productivity of the screw conveyor and power . Design parameters are

mainly two categories, one for the design of screen machinery constant, which is based on the objective laws , the specific conditions as determined by the known data or parameters is given in

advance . Another

Variable is set , it is designed to change in the structural parameters to be determined .
Since a variety of transport of raw materials , screening equipment and the characteristics of raw materials with the type of material , origin, humidity, and preparation and purification effects,

due to a variety of different cable changes , therefore, the main parameters determining the screw conveyor , from which transport mechanism , material properties , etc. into

the

Hands as a variety of tests , made ​​some design parameters , material properties can be designed to meet the screw conveyor .
Tilt angle: angle of the inclined conveyor conveyors process has an impact on the productivity and power consumption , it is generally in the form of a coefficient to reflect

the impact , the screw conveyor transmission capacity will increase as rapidly with increasing inclination angle reduced, while , spiral lose

Tilt angle when sending machine layout will also affect the delivery of materials results. Also the size of the tilt angle also affect the fill factor allowed tilt angle

increases, the allowable fill factor is smaller, the lower the transmission capacity of the screw conveyor . Therefore, to meet the conditions of use of the premise, in this

selection

Horizontal arrangement , improve the transmission efficiency , the inclination angle is zero.
Vibration motor power calculation power of the screw conveyor , the following force to overcome .
( 1 ) to lift the material to be shipped "horizontal or inclined ," the energy required ( 2 ) the material is transported to the trough wall and the screw surface of the

friction caused by the energy consumption ( 3 ) between the particles within the material caused by the relative friction energy consumption: ( 4 ) caused by the movement of

materials along the material he thrust bearing at the Mount

Energy consumption caused by rubbing , and the intermediate bearing and wood at the end bearing the energy consumption caused by friction .
Screw conveyor at a certain speed , the motion of the material particles Akira response is not significant. However, when more than a certain speed sufficient , the material

subjected to excessive force to be tossed tangential , perpendicular to the conveying direction to start generating the radial jump , and thus adversely affect the

transportation process . Therefore

, The maximum allowable speed screw conveyor should be based on the material being transported to determine the minimum jump height
