Conveying capacity: The conveying capacity of the screw conveyor refers to the amount of materials transported in a unit time. When transporting bulk materials, it is calculated by the mass or volume of the materials transported per hour; When transporting finished articles, it is calculated by the number of pieces transported per hour. When it is matched with vibrating screen equipment such as linear vibrating screen, rotary vibrating screen and ultrasonic vibrating screen, the feeding amount of vibrating screen should be calculated and the conveying amount should be controlled. Most conveyors should consider whether they are matched with other production equipment before design and production, so as to design the conveyor model reasonably. 2. Conveying length and inclination: The length and inclination of conveying line directly affect the total resistance and required power of the conveyor. At present, there are many types of conveyors, some of which feed directly in parallel, and some of which have a certain inclination angle, so these conditions should be explained when selecting the screw conveyor. 3. Conveying speed: The conveying speed can directly affect the conveying capacity. When the conveyor belt is used as the traction part and the conveying length is long, the conveying speed is increasing day by day. However, the high-speed conveyor should pay attention to vibration, noise, starting and braking. For the conveyor with chain as traction part, the conveying speed should not be too high to prevent increasing power load. At the same time, the conveying speed of the feeder with process control should be determined according to the production process requirements. 4. Component size: The component size of the conveyor includes conveyor diameter size, hopper volume, blade pitch and container size. The dimensions of these components directly affect the conveying capacity of the screw conveyor. 5. Whether a hopper is added at the inlet and the size of the hopper. 6. The motor of screw conveyor can choose adjustable speed motor and common motor to control the conveying speed and the conveying capacity per hour. Special requirements can be put forward, such as explosion-proof and brand. Selection calculation method: (1) calculation of transportation capacity: Q=47D2ntψρC(t/h) Where: d-screw diameter (m) n-screw shaft speed (r/min) t-pitch (m) ρ-material bulk density (t/m3) ψ-material filling coefficient c-inclination coefficient (when horizontal, C=1). Take ψ = 0.45 for materials (flour, grain, etc.) that are basically wear-free; For less worn materials (sand, cement, etc.), take ψ = 0.33; For materials with large wear (slag, etc.), take ψ=0.15. (2) power calculation: p = P0/(0.8 ~ 0.9) (kw) P0 = q (ω 0l+h)/367+dl/20 (kw). Where: d-screw diameter (m) q-conveying capacity (t/h) ω 0-resistance coefficient l-conveying length (m) h-vertical height (m) when obliquely arranged. /* January 22, 2024 19:08:37 */!function(){function s(e,r){var a,o={};try{e&&e.split(",").forEach(function(e,t){e&&(a=e.match(/(.*?):(.*)$/))&&1
