In 2018, we designed a organic fertilizer line 5T/H for a customer from Hebei YuanBao. This production line adopts monosodium glutamate residue, pig manure and clay as the raw material to produce pellet organic fertilizer, with an annual output of 30000tons. Since it was came into service in early 2018, this production line has been operating well. It has outstanding pelleting effect except for high efficiency. The customer is greatly satisfied.
