BB fertilizer mixers: Key equipment for ensuring uniform nutrient distribution in blended fertilizers

fertilizer granulator Oct 24, 2025

In BB fertilizer (blended fertilizer) production, the BB fertilizer mixer is a key piece of equipment that determines product quality. Its core function is to evenly blend multiple raw materials of varying density and particle size into a nutrient-consistent fertilizer, directly impacting subsequent fertilization effectiveness.

In terms of equipment structure, mainstream BB fertilizer mixers mostly adopt a closed-cylinder design with an internal mixing assembly. The cylinder is typically positioned horizontally, with the mixing assembly driven by a motor. Some BB fertilizer mixers also feature forward and reverse rotation to reduce residual material in the cylinder. The feed inlet is typically located at the top of the cylinder, and the discharge outlet at the bottom. Some models feature an observation window for easily monitoring the mixing status.

During operation, raw materials such as urea, monoammonium phosphate, and potassium chloride are introduced into the mixing cylinder according to the formulated ratio. The rotating mixing assembly propels the raw materials: the screw conveys the raw materials from both ends toward the center, the paddles shear and stir the raw materials, and the guide plates facilitate convection, ensuring full contact between raw materials with density differences of 30%-50%. The entire process does not require the addition of adhesives, and mechanical force is used to achieve “small particles filling gaps and large particles colliding with each other”, ultimately achieving a uniform mixing effect.

Chain crusher: An all-round aid for material crushing in multiple industries

fertilizer granulator Oct 24, 2025

Chain crushers are not limited to organic fertilizer production; they also play a vital role in a variety of industries, including chemicals, building materials, and mining.

Fertilizer granulator machines: Adaptation strategies for different fertilizer types

fertilizer granulator Oct 24, 2025

Many fertilizer companies switch product categories based on market demand. However, if the compatibility of the fertilizer granulator machine with the fertilizer type is neglected, problems such as reduced granule quality and frequent equipment failures can occur.

For organic fertilizers (including straw and fermented manure), the key requirement is “adaptability to the fiber raw material and avoid entanglement and machine blockage.” Flat die granulators or rotary drum granulators are preferred. The vertical extrusion design of the flat die cuts long fibers, and the trapezoidal, non-slip rollers reduce fiber entanglement. Rotary drum granulators use rolling to form the granules, and the lifting plate evenly lifts the fiber material to avoid localized accumulation.

For compound fertilizers (containing phosphate rock and potassium chloride), the key requirements are “high granule hardness and transport resistance.” The high compression ratio of the ring die granulator allows hard mineral raw materials to be extruded with a compressive strength of over 15N, meeting the requirements of long-distance transportation.

For biofertilizers (containing functional microbial agents), the key principle is “low-temperature granulation to protect the activity of the agents.” A flat die granulator (chamber temperature ≤ 40°C) or a disc granulator (rolling, no high-temperature extrusion) can prevent inactivation of microbial agents.

For slow-release fertilizers (including coating materials), “smooth granules suitable for subsequent coating” are required. The rolling forming method of a rotary drum granulator produces smooth, uniformly sized granules, which prevent the coating from detaching during coating.

Windrow compost turning machines: Breaking site constraints and adapting to flexible fermentation

fertilizer granulator Oct 23, 2025

The core of aerobic fermentation of organic fertilizers lies in uniform oxygen supply and temperature-controlled composting. The site adaptability of compost turning equipment directly determines fermentation efficiency and production flexibility. Windrow compost turning machines, with their trackless mobility and all-terrain adaptability, are a perfect fit for the diverse fermentation scenarios in the fertilizer industry.

From a structural perspective, the core advantage of windrow compost turning machines lies in the synergy between their crawler chassis and flexible turning mechanism. Their wide rubber tracks provide a large contact area and low ground pressure, preventing the vehicle from getting stuck even in muddy composting areas or gravel surfaces after rain, eliminating the need for pre-leveling. The chassis’ steering system supports 360° steering, making it easy to navigate obstacles such as raw material piles and equipment around the fermentation area.

In terms of the turning mechanism, most windrow compost turning machines are equipped with double-auger or blade-type turning components, capable of turning compost up to 1.2-2 meters deep and covering compost piles up to 3-5 meters wide. During operation, the equipment slowly moves along the fermentation pile. The turning components throw the bottom material upward and disperse it to the sides, creating a “rolling up and down, mixing side to side” effect. This not only provides sufficient oxygen for aerobic bacteria but also quickly dissipates the heat generated by fermentation.

For fertilizer companies, the value of a windrow compost turning machine lies not only in its flexibility but also in its ability to accommodate multiple fermentation batches. For example, the same site can simultaneously process both a “fresh feed pile” and a “mature compost pile,” allowing the equipment to flexibly switch between different piles, resulting in fermentation efficiency improvements of over 30% compared to track-type compost turners.
