As the "first critical link" in an AAC block or aerated concrete plant, the AAC casting mixer directly determines the uniformity of the AAC aerated concrete paste. This paste uniformity is a key factor in the strength, density, and consistent quality of the final AAC blocks (aerated concrete blocks) and AAC bricks. Designed by Rich AAC Factory, a professional AAC block machinery manufacturer, this mixer seamlessly integrates with the entire AAC production line, connecting the raw material storage system (such as the paste tank) with downstream equipment (such as the belt conveyor and casting molds). Whether in a small aerated concrete block plant or a large turnkey aerated concrete (AAC) production line, it ensures consistent paste quality, optimizes AAC production capacity, and reduces costs, making it an indispensable piece of equipment in any AAC block manufacturing system.
1. Structural Advantages: Uniformity, Intelligence, and Adaptability
The AAC pouring mixer's design addresses core pain points of AAC slurry mixing (e.g., uneven material distribution and difficulty in viscosity control), offering four key structural advantages:
1.1 Twin-shaft Helical Mixing System for Ultra-Uniform Slurry
The mixer's core is a twin-shaft helical mixing structure equipped with highly wear-resistant alloy blades. Unlike the dead zones of single-shaft mixers, the interlocking helical blades create a "360° rolling flow" of material, ensuring thorough mixing of sand, fly ash (for sand/fly ash block plants), cement, aluminum paste, and water. This design eliminates clumping and ensures the aerated concrete slurry meets density standards for aerated concrete blocks (e.g., 500-700 kg/m³) and IS specifications for aerated concrete. Even with aerated concrete and pressurized blocks (a high-performance AAC variant), the mixer maintains consistent slurry viscosity to support subsequent pouring.
1.2 Intelligent Batching and Viscosity Control System
To avoid human error and maintain stable slurry quality, the mixer is equipped with intelligent weighing and real-time sensors. Operators can preset the raw material ratios (for example, sand:cement:fly ash = 6:2:2) on the screen, and the system automatically adjusts the feed rates to the connected slurry tank and silo. Compared to traditional mixers, this intelligent technology reduces material waste by 8-12%, directly reducing the cost of the aerated concrete block machine.
1.3 Seamless Compatibility with the AAC Production Line Ecosystem
The mixer features a modular design that adapts to various aerated concrete production scenarios:
Input: Connects to a slurry tank (for pre-mixed liquid) and a screw conveyor (for dry materials such as cement and sand), supporting both manual and automatic feeding.
Output: Equipped with a movable pouring arm (adjustable in height and angle) that can be aligned with a casting mold or a belt conveyor—ideal for integration with downstream aerated concrete block cutters and autoclaves (key equipment in autoclaved curing brick production lines).
Special Adaptation: For autoclaved lime sand brick production lines or high-grade aerated concrete block plants, the mixer can be upgraded to an insulated tank to control slurry temperature (critical for winter production in cold regions).
2. Simplified AAC Production Operations
Designed to reduce training costs and improve operational efficiency, the AAC pouring mixer seamlessly integrates into the AAC block production process:
The mixer automatically draws dry materials (sand, cement) from the silo and liquids (water, aluminum powder) from the slurry tank according to a preset ratio.
The dual-shaft blades begin rotating (speed: 60-80 rpm), and the viscosity sensor displays real-time data on the touchscreen. If deviations occur, the system automatically adjusts the feed (for example, if viscosity is too high, add 5 liters of water).
Once mixing is complete (the system emits an audible reminder), the slurry remains in the mixing tank and circulates through the anti-settling pipe until pouring.
3. Why choose this AAC pouring mixer?
This mixer offers unparalleled value to investors in AAC block production line projects or those upgrading their aerated concrete block plants:
Quality Assurance: Dual-shaft mixing and intelligent viscosity control ensure AAC blocks meet international standards (such as the IS specification for AAC blocks), reducing defect rates by 15-20%.
Cost-Effectiveness: Automated batching reduces raw material waste, while durable impellers and a low-energy motor reduce maintenance and electricity costs—critical for controlling aerated concrete block costs.
Flexibility: Suitable for small aerated concrete block plants, large automated production lines, and even specialized needs (such as aerated concrete and press block equipment).
