Belt conveyor should move high volumes of flowers, leaves and crops with less power and labor, without letting the herb dust to fall throught the belt or on sides of belt.
Dimensions can be different and depend on what information we will get from You.
Belt has to has ribs allowing maximum operating angle up to 50. It should allow work with herbs where gentle handling is required to minimize damage or dirtying of crops.
Electronic speed reduction should be optional.
Aside to conveyors we need air separators (to separate stones and metals out of herbs), threshing and crushing machine to separate leaves off dried herb, vibration separator or sieve-with possibility to have 4 separations (the last for dust).
