BB fertilizer, the full name is the bulk blending fertilizer. It’s mixed by several single fertilizers or compound fertilizers according to certain proportion and becomes a kind of compound fertilizer. It has characters of granule uniformity, less water, granule intensity moderate, no agglomeration store, easy to use and low cost. BB fertilizer is originated in the United States, the rising of energy prices promotes the development of BB fertilizer.

As professional fertilizer processing machinery supply, we can supply Batch Type and Continuous Type BB Fertilizer Production Line. They are used to produce bulk blending fertilizer efficiently. It is designed according to different soil components in different areas and specific requirements of compound fertilizer factories and chemical fertilizer manufacturers.


BB fertilizer is the direction of fertilizer development in the future, its advantages are:
(1) Comprehensive nutrient, high concentration, reducing cost significantly to increase production, strong pertinence. BB fertilizer nutrient ratio is based on considering the characteristics of crop need, and put forward by the nutrient situation of local soil, both scientific and targeted.
(2) Simple processing, low production cost, no pollution.
(3) Flexible formula, can be flexible changed by the different condition of nutrition, soil fertility and crop yield level, it makes up the shortcoming of the general universal compound fertilizer for fixed ratio of nutrients and easy to cause some kind of nutrient deficiency or excess. BB fertilizer has good solubility so it’s appropriate as base fertilizer.


BB fertilizer is widely applied in foreign countries, especially in the United States, and has broad prospects. Unlike conventional fertilizer, BB fertilizer production method is simple, it should have a certain radius of production and sales of radius, once beyond a certain distance, plus the cost of circulation, farmers will think not economical. Best production radius of BB fertilizer should be kept within 150 kilometers, according to local soil and crop characteristics such as specific formula production area demand. But now some manufacturers often produce tens of thousands of tons, is not suitable for a large number of fat, at the same time it must be long-distance transportation, and run in opposite directions with market demand.

Sets of BB fertilizer equipment are mainly composed of automatic batching & mixing &packing plant, control cabinet, conveyor, sewing machine, pump, motor, and etc.The specifications of BB fertilizer machine are in the following.bulk_blending_fertilizer
