paddle mixer

The mortar production line dedicated Paddle Mixer is the core homogenizing mixing equipment for dry-mix and pre-mixed mortar production lines, specially developed according to the material characteristics of dry powder mortar and special mortar. Adopting a twin-shaft reverse synchronous rotating paddle structure, the equipment realizes sufficient and rapid blending of coarse and fine materials such as cement, sand, fly ash, various admixtures and fibers through multiple mixing principles of material convection, shearing, diffusion and tumbling. With a fully enclosed cylinder structure, it supports intermittent batch production and automatic linkage operation. It effectively solves the pain points of traditional mixing equipment such as uneven mixing, material stratification and fiber agglomeration. It can stably produce all types of mortar including masonry, plastering, waterproof, thermal insulation and floor mortar, and is a standard core equipment for large, medium and small automatic mortar production lines.

• Ultra-high Mixing Uniformity Without Material Segregation: Adopting a three-dimensional circulating mixing design with interlaced twin-shaft paddles, the materials tumble and mix without dead angles in the whole area. The variation coefficient of mixing uniformity (CV) is ≤5%. It can accurately disperse trace admixtures, wood fibers, polypropylene fibers and other special materials, completely avoiding material agglomeration, stratification and color difference, and ensuring the stability of finished mortar.
• High Efficiency and Energy Saving with Excellent Capacity: The fluid dynamics-optimized paddle structure features low stirring resistance and high working efficiency, with lower energy consumption under the same capacity. The single mixing cycle is short, supporting continuous operation of the production line, greatly improving the overall production efficiency of the mortar production line and meeting the needs of large-scale mass production.
• Wear and Corrosion Resistant with Long Service Life: The core vulnerable parts including mixing paddles and cylinder lining are made of high-wear alloy, which is resistant to sand and stone erosion, dust wear and corrosion. It adapts to high-intensity and long-term industrial working conditions with extremely low failure rate, greatly reducing equipment replacement costs.
• Closed and Environmentally Friendly for Clean Production: The fully sealed structure of the whole machine can be seamlessly connected with the dust removal system, effectively inhibiting dust overflow during the mixing process. The workshop dust emission meets environmental protection standards, realizing dust-free, clean and green production.
• Wide Adaptability and Intelligent Compatibility: It is suitable for various materials such as dry powder mortar, dry-wet mixed mortar and special fiber mortar. It is compatible with intermittent manual and fully automatic PLC control systems, and can be linked with batching machines, storage silos and packaging machines to adapt to various production line layouts.
• Convenient Maintenance and Low Operation Cost: The equipment is equipped with a quick-opening maintenance door and detachable paddle structure, which makes internal material cleaning and vulnerable parts replacement simple and fast. The shaft end adopts a multi-layer sealing protection structure to prevent powder leakage, reducing daily operation and maintenance workload.

• Pre-start Inspection: Before starting the equipment, check the fastening state of paddles, ensure no sundries inside the cylinder, intact sealing system and normal oil level of the reducer. It is forbidden to start with materials or overload to avoid equipment jamming and motor burning.
• Standard Feeding Operation: Feed materials strictly according to the mortar formula ratio. Do not add ultra-large particle size sand and stone or metal sundries to prevent damage to paddles and liners. Micro admixtures and fiber materials shall be added in uniform batches to avoid centralized agglomeration.
• Operation Process Control: Do not open the maintenance door or reach into the cylinder during equipment operation, and prohibit long-term overload operation. If abnormal conditions such as abnormal noise, vibration, powder leakage and overheating occur, stop the machine and cut off the power immediately, and restart only after troubleshooting.
• Shutdown Cleaning and Maintenance: After each operation, clean the residual mortar materials in the cylinder in time to prevent material solidification and caking from wearing the equipment. Empty the equipment and do a good job of dust and rust prevention during long-term shutdown.
• Regular Maintenance and Inspection: Regularly check the reducer lubricating oil, bearing wear and shaft end sealing performance, replace worn paddles, liners and seals in time, and fasten bolts regularly to ensure equipment operation stability.
• Electrical Safety Specifications: The electrical system of the equipment shall be protected against water and dust with reliable grounding. Non-professionals are prohibited from disassembling electric control and transmission parts privately, and the main power supply must be cut off during equipment maintenance.
• Environmental Adaptation Requirements: The equipment shall be placed on a flat hardened site with stable horizontal fixation. The supporting dust removal system must be kept open to ensure ventilated and environmentally friendly operation environment.

• Dry-mix Mortar Production Line: Suitable for fully automatic, semi-automatic large, medium and small dry-mix mortar production lines for large-scale batch production of ordinary masonry mortar, plastering mortar and bonding mortar.
• Special Mortar Processing: Applicable to the precise mixing production of various high-demand special mortars suchs as waterproof mortar, thermal insulation mortar, anti-crack mortar, floor mortar, self-leveling mortar and pointing mortar.
• Fiber Modified Mortar Production: Specially adapted to the stirring operation of modified mortars such as polypropylene fiber, wood fiber and glass fiber mortar, solving the problems of uneven fiber dispersion and agglomeration.
• Building Material Powder Mixing: It can be used for the homogeneous mixing production of putty powder, dry powder coating, tile adhesive, grout, gypsum-based building materials and other powder building materials.
• Industrial and Construction Supporting Production: Suitable for on-site mobile mortar mixing stations, standardized production lines of building material factories and prefabricated building mortar supporting production scenarios.
