A stainless steel BB fertilizer mixer for a Tanzanian customer has been successfully completed.

Release time：August 11, 2025

A custom stainless steel BB fertilizer mixer for a Tanzanian agricultural cooperative recently completed all production processes, passed factory inspection, and is about to be shipped to East Africa. Designed specifically for tropical agricultural environments, this equipment, with its corrosion resistance and flexible mixing ratios, has become a key component in localized fertilizer production, further demonstrating the deep adaptability of Chinese fertilizer equipment to the African market.

Targeting Tanzania’s predominantly smallholder, dispersed agricultural model, this BB fertilizer mixer utilizes a 304 stainless steel chamber design, boasting 80% greater corrosion resistance than ordinary carbon steel. It can withstand the local high humidity and long-term corrosion from fertilizer raw materials. Equipped with a twin-ribbon mixing system, the equipment can evenly mix nitrogen, phosphorus, and potassium fertilizers within 5 minutes, achieving a mixing uniformity of 98%. This ensures that the nutrient content of each batch of BB fertilizer does not vary by more than ±1%, meeting the precise fertilization requirements of staple crops such as corn and rice.

Taking into account the unstable power supply and operating habits of the local area, the equipment has undergone multiple practical upgrades. Equipped with a 15kW diesel generator as backup power, it seamlessly switches to a backup power source in the event of a power outage, ensuring continuous production. The control panel features bilingual text in Swahili and English, and includes 12 built-in fertilizer formulas tailored to East African soils. Farmers simply select their crop type and set the raw material ratio with a single click, significantly simplifying the operation process.

Factory test data shows that the mixer can mix 2 tons of fertilizer per hour, with a single unit producing 16 tons per day, sufficient to meet the fertilizer needs of 200 hectares of farmland. On-site verification by experts from the Tanzanian Ministry of Agriculture confirmed that the equipment operates at a noise level of ≤75 decibels, dust emissions meet local environmental standards, and all indicators have passed East African Community agricultural equipment certification.

“The stainless steel material and flexible formulating capabilities are exactly what we need,” the customer representative said during the video acceptance. Previously, imported BB fertilizer from South Africa was not only expensive, but the formula could not be adjusted to suit local soils. After the equipment goes into operation, the cooperative will be able to customize fertilizer based on field testing results. This is expected to reduce chemical fertilizer use by 20%, increase corn yields per mu by 15%, and generate an annual revenue increase of up to $300,000.

To ensure the smooth implementation of the equipment, we have completed a full set of local service arrangements: a three-year supply of consumable parts, including core components such as mixing blades and seals, will be included with the shipment. We have also established an after-sales response mechanism with a Dar es Salaam agricultural machinery service provider, promising on-site repairs within 48 hours. A technical team will also arrive to provide five days of hands-on training to ensure local operators master equipment maintenance and formula adjustment skills.

The completion of this equipment is another achievement in China-Tanzania agricultural technology cooperation. We will continue to focus on the pain points of African agriculture, designing equipment that is more durable and easier to operate, to help more African countries achieve independent fertilizer production and promote agricultural modernization.
