Mobile Concrete Mixer Tank

Shanghe Concrete Mixer Tank

The concrete mixing tank, also known as a mixing drum, serves as the heart of any mixer, where raw materials are combined into a uniform, workable material. Its design is critical to achieving a consistent mix and directly influences the machine’s application, from small-scale projects to large industrial sites.

Key Features

• Mixing capacity: 2-10m³/batch
• Mixing mechanism: the free mechanism, stirring according to the rotating movement of the mixing drum
• Low mobility. The machine is usually fixed in place or pulled at a close distance
• Specialized for mixing slurry, mortar and flexible concrete. Combined with trucks to transport concrete over long
• Feeding: using an excavator
• Discharding: concrete mixture is discharged by reversing the mixing tank

Advantages

Ensured Quality & Consistency

• Uniform Homogeneity: The rotating drum with its internal helical blades provides continuous, thorough mixing. This prevents the segregation of aggregates and cement, eliminating weak spots and ensuring a consistent mix from the first yard to the last.
• Predictable Performance: This homogeneity is critical for achieving the designed structural strength, durability, and longevity of concrete elements, from foundations to beams.
• Controlled Process: Modern systems allow for precise control over mixing time, drum rotation speed, and water addition, guaranteeing each batch meets exact project specifications and maintains the correct water-cement ratio.

Enhanced Efficiency & Productivity

• Optimized Workflow: Mixing in transit eliminates the need for a stationary on-site batching plant, saving crucial setup time and space. Concrete production and delivery become a single, streamlined operation.
• High-Volume Delivery: The ability to transport large, ready-to-pour volumes (typically 6-12 cubic meters) in one trip is essential for large-scale projects, enabling continuous pours and minimizing costly delays.
• Simplified Logistics: Combining mixing and hauling into one vehicle streamlines scheduling and site coordination, freeing crews to focus on placement and finishing.

Direct Cost & Labor Savings

Operational Flexibility & Sustainability

• Site Accessibility: Mixer trucks bring production capability directly to the project, providing vital flexibility for remote sites or locations with limited access to fixed ready-mix concrete (RMC) plants.
• Terrain Versatility: These vehicles can operate in diverse and often challenging site conditions where stationary equipment would be impractical.
• Reduced Environmental Footprint: On-demand mixing and optimized transport routes can lower the overall carbon footprint compared to long-haul deliveries from distant plants, contributing to more sustainable construction practices.

Application

1. High-Volume Infrastructure Projects
These tanks are indispensable for major civil engineering works—such as highways, bridges, tunnels, and dams—that require a continuous, high-volume supply of fresh concrete to maintain pour schedules and structural integrity.

2. Commercial & Residential Construction
They are the standard delivery method for concrete in building projects, used for pouring foundations, floor slabs, columns, and walls in everything from single-family homes to large commercial complexes.

3. Ready-Mix Concrete Distribution
Acting as the vital mobile link in the supply chain, mixer tanks transport pre-batched concrete from central plants to dispersed job sites, using constant rotation to prevent hardening (setting) or separation (segregation) during transit.

4. On-Site Mixing for Freshness
In “transit-mix” operations, dry ingredients and water are loaded separately. The final mixing occurs en route or upon arrival at the site, ensuring optimal freshness and allowing for last-minute adjustments to the mix.

5. Specialized & Confined-Site Work
Smaller-capacity mixer trucks (typically under 6m³) are deployed for projects with access limitations, such as urban sidewalk repairs, interior renovations, or rural builds, where standard large trucks cannot maneuver.

Working Principle

The concrete mixer tank functions as a mobile, rotating blender. Its core operation relies on the continuous or controlled rotation of a cylindrical drum equipped with internal helical blades. This motion ensures the homogeneous mixing of cement, aggregates, and water during transit, preventing the concrete from segregating or setting prematurely.

Core Mixing Mechanism

The process is driven by a rotating drum, typically tilted, with fixed internal spiral blades. As the drum turns, these blades lift the mixture upward. Gravity then causes it to tumble back down, creating a continuous folding and blending action that achieves a uniform consistency.

Operational Phases

Function is dictated by the direction and speed of the drum’s rotation, managed through three distinct phases:

1. Loading & Mixing: The drum rotates in the mixing direction (typically clockwise from the rear). The blade design forces material inward and upward, creating the tumbling action that thoroughly combines all components.
2. Transporting: The drum continues to rotate slowly at a designated agitating speed. This maintains the concrete’s plasticity and prevents settling or initial setting during the journey to the site.
3. Discharging: At the point of placement, the drum rotation is reversed. The blades then guide the mixed concrete outward and downward, funneling it efficiently through the discharge chute.

Power & Control Systems

Precise control over this process is achieved through integrated systems:

• Hydraulic Drive: The truck’s engine (or a separate auxiliary engine) powers a hydraulic system that provides the high torque needed to rotate the heavy, loaded drum.
• Operator Controls: Levers or an electronic interface in the cab allow the operator to select the direction (mix or discharge) and precisely control the rotational speed to achieve the required concrete consistency.
• Onboard Water System: A dedicated water tank and pump enable the operator to adjust mix consistency on-site and perform thorough internal cleaning after discharge to prevent buildup.

How To Choose

Do you have a remote construction site?
Are you working in a tight space?
Need to work on your own schedule rather than the ready-mix concrete company’s schedule?
Is one truckload of concrete too much to handle all at once and you want to save on minimum load or wait time fees
Do you need a way to reduce costs to win your next contract?
