Key features of the Huihong 180 twin-mixer concrete batching plant:

1. The dual-unit 180 concrete mixing plant is a high-quality, energy-efficient, waste-utilizing, and environmentally friendly conceptual concrete mixing station, providing robust support for the production of green, high-performance concrete.

2. The twin-unit 180 batching plant is a closed, green, and environmentally friendly sand-and-gravel weighing and conveying system that minimizes noise pollution.

3. Negative-pressure baghouse pulse dust-collection system, which addresses challenges such as dust emissions and environmental pollution in concrete production, while effectively saving energy and protecting the environment;

4. The concrete separation and recycling equipment features a three-dimensional layout that forms a closed-loop system for wastewater treatment and the recovery of sand and aggregate, enabling complete recovery and reuse of slurry and waste materials to achieve zero discharge, thereby minimizing environmental pollution, maximizing energy conservation and resource efficiency, and ensuring environmentally friendly, comfortable production. 5. The high-precision weighing system employs world-renowned brands for weighing, control, and signal-transmission components, including high-accuracy sensors and imported microcomputer control, supporting both individual and cumulative weighing of various materials with stable performance and precise measurement.

6. The dual-unit 180 mixing station is equipped with a highly reliable, fully automated microcomputer control system that employs an advanced industrial-control-computer–PLC–display-instrument control architecture. The lower-level PLC performs signal sampling and output control, while the upper-level industrial-control computer provides dynamic visualization of the production process and production management; instrumentation further supports the display of batching data for each scale. The system enables both fully automatic and manual operation, featuring simple operation, a user-friendly interface, high reliability, and flexible scalability.

Product Structure

I. Mixing Device

The mixing unit of the 180 m³/h twin-unit concrete batching plant is a dual-horizontal-shaft forced-action mixer, which delivers strong mixing capacity, excellent homogeneity, high production efficiency, and reliable operational performance. It achieves outstanding mixing results for dry-hard, plastic, and all other mix proportions. The mixer’s top cover is equipped with water spray nozzles, maintenance access doors, inspection ports, and a material-feeding system. The feeding system includes inlet chutes for cement, fly ash, and aggregates, as well as a water-injection device. To enhance the impact of water on the main shaft and prevent material adhesion, a pipeline pump is installed on the mixer’s top cover to ensure that the shaft remains free of sticking material.

II. Aggregate Batching and Conveying Section

The aggregate batching and conveying section consists of an aggregate batching machine and an inclined belt conveyor. The process flow is as follows: aggregate yard—storage silo—metering hopper—horizontal belt conveyor—inclined belt conveyor.

1. Aggregate Batching Machine

The aggregate batching machine is equipped with four aggregate bins, typically used for the gradation of up to four types of aggregates. The aggregate bins feed material into the weighing hopper, where a microcomputer-based weighing controller performs batch weighing, enabling functions such as setpoint adjustment, tare compensation, error correction, and output control signal generation.

2. Inclined Belt Conveyor

The incline belt conveyor consists primarily of a conveyor belt, drive unit, idlers, cleaning device, frame, and access ladder. After the measured aggregates are conveyed by the horizontal belt conveyor, they are fed into the intermediate storage hopper via the incline belt conveyor. Inspection walkways are provided on both sides of the incline belt conveyor, and chutes are installed underneath to prevent material spillage.

III. Powder Storage and Conveying System

The powder storage and conveying system consists of cement silos and screw conveyors. The process flow is as follows: powder silo → screw conveyor → powder metering hopper.

1. Cement silo

The cement silo is a steel structure comprising a support frame, a cylindrical shell, a flip-door discharge gate, a roof-mounted dust collector, an arch-breaking device, and a conveying pipe. Powder materials are conveyed into the silo under pressurized air through the conveying pipe, while pressurized gas generated inside the silo is discharged via the roof-mounted dust collector. Each cement silo is equipped with upper- and lower-level material level indicators that display the silo’s empty or full status.

2. Screw Conveyor

A screw conveyor is a device that feeds powdered materials from a silo into a metering hopper for precise measurement. It primarily consists of a power transmission unit, a screw shaft, a casing, intermediate support bearings, and inlet and outlet pipes. It features high conveying capacity, excellent sealing, zero dust emissions, and modular assembly for easy transportation.

IV. Measurement System

The batching system of a 180-type concrete mixing plant is divided into three parts: aggregate weighing is conducted via static metering, with belt scales and bucket scales as the primary options; cement and other powdered materials are weighed using single-point metering, typically with bucket scales; and mixing water and admixtures are generally measured either by flow meters or by bucket scales.

V. Control Room

The control room of the 180-mixing station with two mixing units features a vertical structural design, with walls clad in lightweight insulated panels. It houses an electrical control and operating system, and is equipped with a large, flat glass window at the front, providing unobstructed views and ample natural light.
