Wanjie shaftless screw conveyor is mainly used in the chemical, food, pharmaceutical, paper, beverage, environmental protection and other industries to transport more adhesive materials, paste-like viscous materials (such as chemical raw materials, waste paper pulp, malt, sludge, etc. ) and easy-wound materials (such as domestic garbage), which are continuous transportation equipment for conveying dust, small particles and small blocks, which can be transported horizontally and obliquely, and have unique advantages. The conveying capacity is 1.5 times that of the conventional shaft screw conveyor of the same diameter. The conveying distance is long. The single machine can transport up to 60 meters in length. And according to user needs, custom non-standard specifications series.
The calculation formula of the transportation volume:
1 Delivery volume Q=47b•j•r•D2•S•n(t/h)
Where: b-inclination coefficient, see Table 2, j-material fill factor, r-material bulk density (t/m3), D-diameter m, S-pitch m, n-speed r/min. The filling factor is generally: good fluidity, mildly abrasive powder and fine granular materials take j=0.45 (such as grain), general mobility, medium abrasive materials take j=0.33 (such as coal, ash, cement) , the greatly abrasive material takes j = 0.15 (such as slag, river sand).
2 speed
The rotation speed of the shaftless screw conveyor is not allowed to be too large, otherwise the material to be conveyed is subjected to strong centrifugal action, which affects the conveying process. Refer to JB/T7679-95 "Shaftless Screw Conveyor" standard. There are 4 kinds of speeds for each specification. Choose 4 times longer.
3 spiral diameter
The minimum helix diameter is determined by the rotation speed and the conveying amount, and the following conditions are satisfied: for conveying the bulk material, the spiral diameter D should be at least 10 times the maximum side length of the particles, and if the content of the large particles is small, a smaller spiral diameter may be selected. .
4 motor power
P=0.9[Q(λ?L+H)/367+D?L/20]
N=K?P
Where: P-power kw, Q-transport amount t/h, λ-running drag coefficient, L-helix length m, H-helix tilt height m, D-helix diameter m, N-motor power kw, K-power factor . (end)

Pesticides are substances that are meant to control pests or weeds. The term Pesticide includes all of the following: Herbicide, Insecticide, insect growth regulator, nematicide, termiticide, molluscicide, piscicide, avicide, rodenticide,predacide, bactericide, insect repellent, animal-repellent, antimicrobial, Fungicide, disinfectant (antimicrobial),
and sanitizer. The most common of these are herbicides which account for approximately 80% of all pesticide use. Most pesticides are intended to serve as plant protection products, which in general, protect plants from weeds, fungi, or insects.
