BB Fertilizer Mixer

The raw materials processed by the BB fertilizer mixer include granular fertilizer ingredients—such as urea, potassium chloride, monoammonium phosphate (MAP), diammonium phosphate (DAP), and potassium sulfate—in the form of spherical or oblate granules. The materials should have similar specific gravities and particle sizes; generally, the moisture content should be less than 2%, and the materials should be free from significant caking or stickiness.

The working principle of the equipment

The BB fertilizer mixer utilizes the principle of gentle convective blending. Materials undergo brief, mild tumbling and convective mixing within a specially designed mixing chamber. Unique helical ribbon or paddle configurations induce simultaneous axial and radial circulation of the materials without exerting strong impact forces. The system operates with reversible rotation and utilizes a batch-wise, intermittent mixing process.

Equipment operating instructions

(I) Pre-loading preparations: Check the stability of the mixer body. Inspect the mixing blades and the drive system. Screen raw materials to remove impurities and ensure that the particle size of any agglomerates does not exceed 5 mm.
(II) Loading operation: Follow the principle of "light before heavy, fine before coarse, and dry before wet."
(III) Mixing and discharging: Control the mixing time. Open the discharge gate quickly once mixing is complete.

Equipment maintenance methods

(I) Routine Maintenance: Thoroughly clear out accumulated material from the machine after each shift. Promptly repair or replace blades with wear exceeding 5 mm. Inspect mechanical components regularly (1–2 times per month).
(II) Periodic Lubrication: Periodically replace grease in all bearings. Regularly apply high-temperature lubricant to the lifting guide rails.
(III) Seasonal Maintenance: Repaint the machine frame with protective coating after the production season ends.
