Why does the scraper chain serve as a conveyor?

The same machine can be used to spread various bulk materials, such as:

-mineral fertilizers, also with lumps
-lime in any form, including wet lime
-dry poultry manure, compost, etc.

How accurately does the spreader apply the fertilizer?

The conveyor speed is electronically controlled. With freely variable speed, working width and application rate, the dosage accuracy is 1-2%. The distance between the chain links is very narrow. The chain is covered on the sides to prevent fertilizer from getting into the links. It is automatically cleaned at the rear.
