Single bag batching and blending system: Automatic BB fertilizer formulating, blending and bagging system is a proprietary product developed by Qinhuangdao Sannong Modern Mechanical Equipment Co., Ltd with patents. The first single bag blending and bagging system was built in 2001. It has well performed in domestic and overseas markets since then. It is suited for low production rate from 5 tons/ hour to 15 tons/hour.

It formulates,blends and packs fertilizer one bag at a time with bag weight from 20 Kg through 50 Kg. This eliminates segregation of the blends caused by difference of granule size and  density of the ingredient materials and improves formulation accuracy. This system is well suitable for operation in humid area as the way of operation minimizes moisture to get access to the blends. This system is fully automatic, high in precision and speed, less floor occupancy and easy in operation and maintenance. The stainless steel components give the equipment sound anti-corrosion capability and long service life.
