How do BB fertilizer companies of different production capacities choose the right mixer operating mode?

The differences in production capacity among BB fertilizer companies (small-scale with daily production capacity below 50 tons, large-scale with daily production capacity above 100 tons) directly influence the choice of BB fertilizer mixer operating mode. Choosing the right mode can improve efficiency by over 30%.

Small-scale companies often operate in batch mode, making the “batch mixing + staged feeding” mode suitable: the single mixing volume is set at 70% of the equipment’s capacity, and feeding is carried out in three batches: 60% base granular fertilizer is added first, followed by 30% powdered raw materials after three minutes of mixing, and finally 10% trace additives. The total mixing time is kept to 10-12 minutes. This mode avoids energy waste caused by idling equipment for small batches of raw materials and facilitates flexible switching of fertilizer formulas.

Large-scale continuous production companies require a “continuous mixing + flow linkage” model: raw materials are continuously fed into the BB fertilizer mixer in proportion via a conveyor belt. The raw material flow rate is linked to the mixing speed. An online detection device is installed at the BB fertilizer mixer outlet to monitor mixing uniformity in real time. If the coefficient of variation exceeds 5%, feedback is immediately provided to adjust the feed ratio. Furthermore, continuous production requires cleaning of the drum wall every four hours to prevent long-term accumulation that can affect the quality of subsequent batches.
