Apa khabar, weien,
It would help if you would explain your problem in much more detail.

Explain More About It
khabar baik.
thanks for reply my post.
Ya we are actually plan to design a harvester using the conveying system with a membrane layer stick together on the belt.the length of the belt is 2m long (just the upper part* total length is approximately 4m) and width of 1m. The slope angle is around 10-15 degree.We assume the algae will stick on the membrane in thin layer when harvesting so we plan to do the calculation by following the conveyor system calculation.the mass on top of is approximately 25kg evenly distributed on the conveyor belt.The speed of conveying is around 2m/minute.
thanks and regards

Re: Conveying System To Harvest Algae
Seems straightforward enough. You have a flat belt conveyor 1m wide x 2m long, half in the pond of algae and half out. If there is only a thin layer of algae on the belt (have you tested this?) this will not require a significant amount of power. Your power will mainly be that to overcome bearing friction on the head and tail shafts, sliding friction of the belt on it's supports, the flexing the belt around the pulleys and the friction of the head scraper that removes the algae from the belt.
I suppose you could scratch around with pencil and paper for a couple of days and try to estimate the power, but I'd be looking at setting up some simple tests on a bit of belting and using these as the basis of deriving the necessary power. ■

ya thanks for your reply.we have not tested on this yet but got 1 research have proved it.so we assume that it works. ■
Calculate Static Force
may i know why i calculated the static for static force would get zero?it is a fix support

Conveying System to Harvest Algae
i m student from University of malaya.
May i know if i want to design i conveying system to harvest algae. what should i start with the calculation?what factors should be consider?and how to chose the suitable a motor?thanks for helping me to get some idea. ■
