Concrete Batching Machine
Products Description
AGICO concrete batching machine is a core auxiliary equipment at the front end of a concrete batching plant. It is specifically designed for automatic batching of aggregates with different particle sizes, such as sand, gravel, and crushed stone.
High performance design
The AGICO concrete batching machine adopts a modular bin design combined with high-precision sensors. It integrates functions of material storage, weighing, and discharging. The main structure of the batching machine's bin is made of Q345 high-strength steel and treated with anti-rust painting.
High standard performance
The AGICO batching machine supports two operation modes: single weighing and multi-weighing . It can handle 2 to 6 types of aggregates. The weighing accuracy is controlled within ±2%.

Products Specification
The AGICO concrete batching machine consists of five main parts: storage bins, weighing system, discharge mechanism, frame, and control system.
The storage bins have a "V" shape or a "rectangular box + inclined plate" structure. A belt conveyor or pneumatic gate is installed at the bottom. A key design feature is the removable bin partition, which allows users to adjust the volume ratio of different aggregate bins according to site needs.
The weighing hopper is suspended under the frame using 3 or 4 tension or compression load cells. Limit tie rods are used to prevent shaking. The discharge gate uses a rubber sealing strip and a pneumatic actuator. There is no leakage when the gate is closed.
AGICO offers PLD series models (800, 1200, 1600, 2400, 3200, 4800) and custom models. The weighing hopper volume ranges from 0.8 m³ to 4.8 m³. The corresponding maximum weighing capacity ranges from 1500 kg to 8000 kg. The number of aggregate types (bins) can be 2, 3, or 4. Notably, the AGICO PLD4800 model can weigh up to 8000 kg of aggregate per batch. Its theoretical productivity reaches.

Why Choose AGICO
AGICO concrete batching machine adopts "coarse and fine dual-speed control"
Traditional batching machines tend to exceed the target weight due to material discharge inertia. AGICO batching machine uses a two-stage pneumatic gate control technology: the gate opens quickly at the beginning for coarse feeding, and closes partially for slow fine feeding when approaching the target value. This effectively eliminates the overshoot caused by aggregate impact. It ensures that the dynamic weighing accuracy remains stable within the industry standard of ±2%, protecting the concrete mix accuracy from the source.
AGICO concrete batching machine adopts an arc-shaped gate to prevent material jamming
For working conditions where wet sand with high clay content or large-sized gravel tends to block the gate, AGICO designs the discharge gate as a dead-angle-free arc or trapezoid shape. A polymer wear-resistant liner is added to reduce the friction coefficient. Even under high-load operation for more than 10 hours of continuous production, discharge remains smooth, avoiding shutdowns and cleaning caused by material jamming.
AGICO concrete batching machine supports "independent weighing for each material"
For high-grade concrete that requires precise control of multiple aggregate ratios, AGICO provides an independent weighing configuration of "one bin, one scale". Each aggregate type has its own weighing hopper and load cell. This is 20% more efficient than accumulative weighing. It also avoids the problem of aggregates interfering with each other's weight readings. It is especially suitable for pipe piles and high-speed rail precast parts, which have high requirements for mix ratios.
AGICO concrete batching machine uses heavy-duty load cells with a shock absorption structure
Given the frequent impact on the batching machine, AGICO selects alloy steel load cells with a range redundancy of more than 1.5 times. Buffer springs and limit devices are equipped to effectively reduce the impact force at the moment of material discharge. The load cell signal is processed through a dedicated anti-interference filter before entering the control instrument. Even in noisy environments where vibrating screens and conveyors run at the same time, the system outputs stable and accurate weight data.

FAQ
Q: What is the difference between "accumulative weighing" and "independent weighing" on AGICO concrete batching machine?
A: Accumulative weighing means different aggregates fall into the same weighing hopper one by one for cumulative weighing. It has low equipment cost and a small footprint. It is suitable for ordinary roads or low-grade concrete with less strict mix ratio requirements. Independent weighing means each aggregate type has its own weighing hopper and load cell. All are weighed and discharged at the same time. It has higher efficiency and better accuracy. It also avoids interference between aggregates.
Q: When using an AGICO batching machine, how can we solve the zero drift problem caused by wet sand and stone sticking to the inner wall of the weighing hopper?
A: AGICO provides two solutions. The first is to add a high-frequency vibration motor on the outer wall of the weighing hopper. It vibrates automatically for 3-5 seconds after each discharge to shake off residual material. The second is to line the inner wall of the hopper with ultra-high molecular weight polyethylene (UHMWPE) plates. Their very low friction coefficient (≤0.1) makes it difficult for wet sand to stick.
Q: What causes data fluctuation on the AGICO batching machine's load cell after a period of use?
A: Data fluctuation is usually caused by loose mechanical limiters or load cell damage due to overload. AGICO batching machines are equipped with anti-overturn limit tie rods and buffer springs at the factory. First, check whether the limit tie rod is too tight or completely detached (about 2mm gap should be kept). If the problem remains, it may be caused by fatigue of the strain gauge inside the load cell from long-term impact.
Q: Can the AGICO batching machine adapt to my existing batching plant control system of a non-AGICO brand?
A: Yes, it can. The AGICO batching machine uses a standard 4-20mA analog signal or RS485 Modbus communication protocol to output weight data. We also provide an independent weighing indicator (which can display weight and control the pneumatic gate). This indicator can run independently as a local control station. It can also exchange data with any of your existing third-party PLCs (Siemens, Mitsubishi, Omron, etc.) through dry contacts (digital signals) or serial communication.
