PRODUCT COMPONENTS
The main components of this station are: mixing system, batching machine, hopper lifting system, main building, water line, admixture line, gas line, control system, etc. The following is a detailed reference for the introduction of each component：
1. Mixing system
The YJS series concrete mixers (currently available in 1m³, 1.5m³, 2m³, 3m³, 4m³, and 6m³ sizes) are highly mature models developed by our company and are internationally advanced. They are suitable for mixing concrete for high-speed railways, various road surfaces, bridges, dams, airports, buildings, and urban commercial concrete. These mixers utilize a twin-shaft forced mixing system, enabling them to fully mix dry-hard, semi-dry-hard, and plastic concrete, as well as concrete of various proportions, in the shortest possible time, meeting the requirements of diverse working conditions.
1) Mixing drum system：
The mixer consists of a cylinder, a cover, and accessories, serving as a carrier for the mix and supporting various components. The cylinder, formed from high-quality, wide, thick steel plate, is shaped like an ω-shaped barrel. Supported by a specially designed and manufactured multifunctional frame, it possesses excellent yield strength. The support also provides sufficient rigidity to ensure parallelism of the twin shafts and concentricity of the single shaft.
2) Mixing System：
The mixing system consists of agitator shafts, agitator arms, agitator blades, and a drum lining (wear-resistant lining). The mixing system utilizes two parallel horizontal shafts that rotate in opposite directions. The direction of rotation is clockwise when facing the right side of the shaft (head or tail); counterclockwise when facing the left side. The agitator arms and blades on the two shafts rotate in an alternating pattern, with the number of blades varying depending on the mixer model. These blades, combined with appropriate clearances and operation, achieve a perfectly uniform mixing effect in a short period of time.
3) Drive System：
Comprising a mixing motor, a high-quality speed reducer, pulleys or gears, a synchronizer, and a protective cover, the system synchronizes the two mixing shafts from high speed to low speed. The entire system offers a compact structure, smooth operation, and high transmission efficiency.
4) Sealing and Lubrication System：
The shaft end supports and seals are completely separated to prevent bearing damage in the event of a seal failure. The six-fold shaft end seal effectively prevents mortar intrusion, significantly reducing the possibility of slurry and oil leakage from the shaft head, achieving a perfect seal. The lubrication system utilizes the most reliable manual or automatic oiling system, quickly and efficiently pumping lubricant to all lubrication points and seal chambers, ensuring lubrication and sealing.
5) Discharge System：
Comprising the discharge door body, bearings, limit switches, and an air or oil cylinder, the entire system features tight sealing, quick door opening, compact structure, smooth operation, precise door opening positioning, and automatic or manual door opening.
2. Batching Machine
The batching machines used in this station are the PLDF (single-dosing) or PLD (accumulative dosing) series, independently developed based on advanced technical experience and market feedback. We also offer both ground-mount and above-ground batching machines, tailored to individual user requirements.
Structural Overview:
This batching machine primarily consists of a frame, aggregate silo, weighing hopper, belt conveyor, and pneumatic control system.
1) Frame：
The frame serves as the support for the entire batching machine and is constructed from a variety of profiles. Upon request, a monitoring device can be installed to monitor the flow of material from the conveyor belt to the inclined belt.
2) Storage Bin：
The storage bin features a conical structure with one or two long, narrow discharge doors at the bottom, which are pneumatically controlled. When two discharge doors are installed, their openings vary to control aggregate metering accuracy. The aggregate hopper feeds the aggregate into the lower weighing hopper according to a program set by the weighing controller. Before 90% of the total batched material is filled, both discharge gates discharge simultaneously. Once 90% is reached, the larger discharge gate closes, and the smaller discharge gate discharges material. This allows for both coarse and fine weighing of the aggregate. The weighing hopper sensor uses a pressure sensor to prevent measurement errors caused by hopper shaking during weighing, ensuring that the measurement meets national metrology requirements. The aggregate batching accuracy is ±2%.
3) Weighing Hopper：
The weighing hopper is mounted on a frame below the aggregate hopper. A high-precision weighing sensor is mounted on the hopper support. When the aggregate hopper feeds the weighing hopper, the microcomputer-controlled weighing controller weighs the various materials, performs weight settings, tare, and compensates for the difference, and outputs signals to control the cylinder's operating timing, ensuring that each hopper feeds the aggregate to the lower belt conveyor according to the set program.
4) Belt Conveyor：
When the aggregate in the weighing hopper reaches the set value, the belt conveyor starts. After feeding is complete, the belt conveyor stops and enters the next weighing cycle. A belt conveyor primarily consists of a drive unit, tensioning device, transmission components, frame, and sweeper.
5) Pneumatic Control System：
The pneumatic control system consists of an air reservoir, a dual-body assembly, a solenoid valve, and an air cylinder, and is used to control the opening of the material gate.
3. Hopper Lifting System
The feeding system consists of a winch mechanism, guide rail brackets, guide rails, and a hoisting hopper.
A brake motor drives the drum through a reducer. A wire rope passes through a pulley, pulling the hopper upward along the feed frame track. When it reaches a certain height, a pair of rollers on the hopper door enter a horizontal branch on the feed frame, automatically opening the door and allowing material to be released into the mixing tank through the feed hopper. To ensure the hopper is positioned accurately, limit switches are installed on the feed frame. Two limit switches are located at the upper position, providing both hopper position control and safety protection. A lower limit switch is located on the crossbeam of the feed frame. When the hopper reaches the bottom of the pit and the wire rope slackens slightly, a spring-loaded lever mechanism activates the lower limit switch, automatically stopping the winch.
The brake motor ensures that the hopper remains securely in position even when fully loaded. The braking torque is adjusted by a large nut on the rear seat of the motor.
4. Main Building
The main building is the core of this product, housing the powder metering, liquid metering, mixing device, and hopper. Its metering accuracy meets national standards. The overall layout is rational, the structure is simple, compact, and easy to maintain. It is finished with color-coated corrugated steel sheets or sandwich panels (optional), creating a sleek appearance. An internal axial flow fan (optional with the outer packaging) prevents dust from spreading, complying with national environmental regulations.
1) Powder Metering System：
This system consists of a cement scale, fly ash scale, mineral powder scale, and scale stand. To reduce procurement costs, users can also choose two types of cumulative powder metering, allowing users to select the desired powder quantity based on their needs.
The system utilizes advanced computerized weighing instruments to control weighing. Powders such as cement, fly ash, and mineral powder are typically stored in powder tanks, and a screw conveyor transports the powders to the metering silo for weighing. At the start of operation, cement, fly ash, or mineral powder, among other materials, are fed into the weighing hopper via a powder conveyor according to a pre-set schedule. The weighing is controlled by a computerized scale. When the set weight is reached, the control system automatically stops metering that material (or activates another material conveyor until all the materials are metered). A few seconds after the aggregate is added (the specific time can be set as needed), the controller sends a signal to the outlet butterfly valve cylinder, opening it and releasing the powder into the mixer. A single metering process begins when the butterfly valve in the weighing hopper closes, the screw conveyor feeds the material into the hopper, and the process ends until the screw conveyor stops and the butterfly valve opens to release the material.
To prevent the compressed air in the hopper from compressing, which could affect metering accuracy, the powder scale is equipped with a specially designed exhaust port and pressure reducer. A vibrator is also included to prevent bulging of the powder in the scale and to ensure that the hopper is empty and unloaded within the specified time. High-quality, highly stable sensors ensure accurate and reliable metering. Flexible connections are used at the loading and unloading points to ensure flexibility and metering accuracy.
2) Liquid Metering Device：
This device is used to weigh liquid materials (such as water and liquid additives) and primarily consists of a scale, butterfly valve, and sensor.
Water metering is controlled by a microcomputer-based weighing instrument. A water pump draws water from the customer's own water source into the water weighing hopper. Water weighing utilizes both coarse and fine metering, significantly improving metering accuracy. A few seconds after the aggregate is released (the specific time can be set based on actual conditions), a computer signal activates the unloading pump located below the water weighing hopper to rapidly unload water into the mixing pot. When the water level reaches zero, the unloading pump stops and the submersible pump activates to initiate the next metering sequence.
Admixture metering is controlled by a microcomputer-based weighing instrument. A water pump delivers admixture directly from the surface admixture storage tank to the admixture scale. At this time, the butterfly valve below the hopper is closed. Admixture weighing utilizes both coarse and fine metering, significantly improving metering accuracy. A few seconds after the aggregate is released (the specific time can be set based on actual conditions), the computer generates a signal to open the butterfly valve below the scale body. The admixture flows by gravity into the water scale and enters the mixer along with the water. When the admixture level drops to zero, the computer generates a signal to close the discharge butterfly valve and initiate the next metering process. Since the metered admixture is directly injected into the clean water scale and enters the mixer along with the water, it is diluted upon entry, resulting in more uniform mixing.
3) Hopper：
This equipment features a wear-resistant liner inside the hopper to prevent wear through the hopper body. For user convenience, the liner is bolted together for easy replacement.
5. Water, Admixture, and Gas Systems
The water, admixture, and gas systems primarily consist of a water pump, gas line, piping accessories, an air compressor, a gas storage tank, an oil-water separator, connectors, a solenoid valve, and an air cylinder. To ensure overall performance, all components are brand-name.
6. Exterior Spraying
Our products undergo sandblasting and shot blasting for rust prevention before leaving the factory. Both the primer and topcoat are made of reputable materials, ensuring both the internal and external quality of our products is superior.

5) Configurable software features, strong compatibility, wide applicability, and high stability:
The system software features configuration capabilities, allowing for rapid system customization. Each system undergoes laboratory simulations before leaving the factory, ensuring reliable and stable operation.
6) Automatic and manual control during batching:
In automatic mode, pre-set production dispatch queues enable continuous multi-task and multi-formula production, enabling separate or mixed production of concrete and mortar. In manual mode, batching of each material is fully controlled manually. By coordinating with a computer, the system can also operate semi-automatically (automatic batching, manual unloading and mixing).
7) Dual control:
When the computer system is functioning properly, fully automated production is controlled by the computer. If the computer system fails, full automation can be achieved through touchscreen operation. This dual control system provides a double safeguard. An additional computer can be added upon customer request, creating a triple safeguard for dual machines and triple controls.
8) Flexible Production Mode:
Aggregates and powders can be fed individually in a chronological or pre-set order to meet process requirements. Each material can be fed in single, double, or even triple batches, or in stages (to meet special requirements such as sand-encapsulated stone). The pre-storage hopper can also be configured for secondary feeding. Multiple mixing timing modes are available (when the pre-storage hopper begins feeding, when the pre-storage hopper is fully fed, and when all materials are fed into the mixer).
9) Online Adjustment of Production Data:
The number of production batches can be increased or decreased during production. Aggregate moisture content can be adjusted automatically or manually to ensure concrete quality. All raw material settings can be modified and take effect immediately. Bin switching between the same and different scales is possible.
Online Adjustment of Control Parameters: Control parameters (mixing time, discharge time, loading method, etc.) can be modified during production with immediate effect.
10) Automatic Tare and Automatic Head Correction:
The batching controller not only performs automatic tare but also automatically corrects head differences. The control software includes a built-in "head difference library" for automatic head difference correction. 11) Automatic Out-of-Tolerance Processing: Through collaboration between the batching controller and the computer, the system enables automatic weighing and replenishment, and can automatically deduct and replenish water as needed.
12) Automatic Arch Breaking and Automatic Alarm:
The system can automatically break arches based on time or flow rate, and an automatic alarm signals completion upon completion.
13) Automatic Recording of Manual Production Data:
