Double Axis Mixer
The double shaft paddle mixer is widely used in the organic and compound fertilizer industries due to its rapid mixing speed, high uniformity, and reliable performance. Featuring a staggered arrangement of twin-shaft paddles, the equipment creates a high-efficiency mixing zone within the trough, enabling uniform blending in a short time. Both the paddles and the trough are constructed from wear-resistant materials, making the unit suitable for continuous, long-term batch operations. With reliable shaft-end sealing and easy maintenance, it is an efficient choice for the batching stage of organic fertilizer production lines.
Working Principle
Two horizontal main shafts rotate in opposite directions, with the paddles exerting multi-directional forces on the material. The material is pushed axially in both directions by the paddles while simultaneously undergoing radial shearing and vertical turnover. A cross-convection flow forms between the two shafts, causing particles to continuously pass through the interaction zone. The material mixes rapidly amidst vigorous movement, ensuring consistent composition throughout the trough. Discharge occurs once the set processing time is reached.
Performance Features
Rapid mixing speed: Strong twin-shaft convection ensures short batch mixing times and high production efficiency.
High uniformity: Thorough material convection and diffusion result in a low coefficient of variation in the mixture.
Wide application range: Capable of mixing powders, granules, and semi-wet materials.
Durable wear parts: Paddles are made of wear-resistant material, ensuring a long service life.
Excellent sealing: Multiple shaft-end seals prevent dust leakage.
Maintenance Instructions
Clean residual material from the trough and paddles and check paddle fastening bolts after every shift.
Check the condition of shaft-end seals weekly; replace seals promptly if leakage is detected.
Check the gearbox oil level and gear meshing status monthly; top up or replace lubricating oil as needed.
Inspect paddle wear quarterly; replace paddles if wear is severe.
Conduct a comprehensive inspection of shaft synchronization, bearing clearances, and seals during the annual overhaul; replace worn components.
