0086-138 3838 9622Manure-to-fertilizer conversion projects have been picking up across Eastern Europe, and the latest signing is a 10 t/h cow dung organic fertilizer pellet production line headed for a dairy operation cluster in Poland.
This isn’t a single-machine sale. The scope covers a horizontal mixer for blending dewatered cow manure with bulking agents (in this case, a mix of straw fines and a small percentage of NPK additive per the buyer’s soil testing results), a rotary drum granulator, a three-layer drum dryer, rotary cooler, and a screening/coating line for the finished organic fertilizer pellets.
Moisture management is the whole game with cow dung. Raw manure can sit at 70-80% water content depending on the dairy’s bedding and separation system. The buyer’s solids separator gets it down to roughly 55% before it enters RICHI’s line — still wet enough that the dryer has to do real work.
Pellet size target is 3-5mm for direct field application via standard fertilizer spreaders. The buyer’s agronomist specified an N-P-K blend ratio that varies seasonally, so the mixer’s dosing system needed to be flexible rather than fixed-ratio — something RICHI’s design team adjusted during the proposal stage after a few rounds of back-and-forth.
Equipment fabrication begins this month, with shipment targeted for early next quarter. Site visits for foundation inspection have been scheduled remotely via video walkthrough given the distance.
