0086-138 3838 9622Equipment specifications have been finalized for a 9 t/h sheep manure organic fertilizer pellet line headed to a livestock processing zone in Mongolia, following several rounds of revisions based on local conditions.
Sheep herding operates at enormous scale across Mongolia, and manure collection from semi-permanent grazing camps has typically meant the material arrives at any central processing point already quite dry — sometimes below 30% moisture, which is unusually low for manure-based fertilizer feedstock and actually changes the equipment requirements compared to, say, a dairy operation’s wet manure.
Lower incoming moisture means less drying capacity is needed, but it also means the granulator needs supplemental water addition during the mixing stage to achieve proper granule formation — too dry, and the material won’t bind into pellets at all, it just stays as loose crumbs.
The finalized equipment list: pre-crusher for breaking up dried manure clumps, mixer with a water spray system for moisture adjustment, drum granulator, a smaller dryer than typical for this capacity (given the lower moisture starting point), cooler, and screening with returns.
Pellet size is 4mm, formulated with a small percentage of humic acid additive — sourced by the buyer from a domestic supplier — to improve soil conditioning properties for the region’s grassland and limited crop areas.
One revision during the spec finalization process: the original proposal included a rotary dryer sized for 55-60% moisture input, standard for most manure fertilizer lines RICHI builds. After the buyer provided actual moisture test data from collected samples (averaging 28%), RICHI’s team reduced the dryer size by roughly 40% and added the water spray system to the mixer instead — resulting in lower equipment cost and energy consumption for the buyer, better suited to the actual feedstock.
Manufacturing will begin once the buyer confirms the additive specification documentation, expected within the next week or so.
