Advanced Automatic Mixer Truck Washing Machine Factory

SINOU is a reliable manufacturer of Automatic Mixer Truck Washing Machine, which is a dedicated intelligent cleaning solution developed exclusively for ready-mix concrete fleets, construction mixers and bulk engineering vehicles.

Different from ordinary civilian washers and simple manual flushing devices, this equipment integrates intelligent sensing, high-pressure water jet, full-range decontamination and closed water recycling into one set. It targets stubborn concrete mortar, hardened cement scale, mud and gravel attached to mixer truck hoppers, mixing drums, tires and undercarriages.

Designed for 24/7 continuous operation in harsh construction environments, the whole machine realizes driver-on-board washing without alighting. It effectively cuts manual cleaning risks, reduces water consumption and complies with strict global environmental regulations.

Widely deployed at concrete batching plants, municipal construction yards, mining bases and large vehicle depots across the Middle East, Europe and Southeast Asia, it has become a standard supporting facility for modern green concrete production lines.

Dual Working Modes & Operating Flow

This washer supports automatic drive-through mode and manual fixed-point mode to adapt to different cleaning demands. The overall workflow is streamlined and highly efficient.

(1) Automatic Drive-through Mode

① Intelligent Trigger: When a mixer truck enters the designated washing lane, microwave sensors (higher anti-interference than infrared sensors) identify the vehicle and activate the entire system automatically.

② Omnidirectional High-pressure Cleaning: Multi-group top, side and undercarriage spray arms launch 3D high-pressure water jets to strip cement dirt, hardened mortar and mud from every corner.

③ Sewage Collection & Recycling: All wastewater flows into the underground multi-stage sedimentation tank. After sludge separation and filtration, clean water is pumped back to the water supply system for cyclic use.

④ Auto Stop & Reset: The system stops spraying once the vehicle exits the sensing area, and returns to standby for the next vehicle. A full cycle takes only 50–70 seconds.

(2) Manual Fixed-point Mode

Operators control the spray system via the touch panel to perform targeted flushing on heavily contaminated areas such as mixing drum outlets and feed hoppers. This mode is ideal for vehicles with long-term concrete accumulation or after overnight parking.

Modular Structure & Key Components

Adopting integrated modular design, the equipment is easy to transport, assemble and maintain. All core components are selected for anti-rust, wear and low-temperature resistance to adapt to desert high temperature and rainy humid areas.

(1) Heavy-duty Load-bearing Platform & Main Frame

Constructed with hot-dip galvanized H-beam and thick steel plates, the platform has a rated load of 100 tons, resisting long-term rolling of fully loaded mixer trucks.

The overall frame adopts bolted + welded composite structure, avoiding welding cracks caused by vehicle vibration. Multi-layer anti-corrosion coating is applied for outdoor long-term service.

(2) High-pressure Water Supply & Spray Arm Assembly

Equipped with industrial multistage high-pressure water pumps with stable water pressure up to 110 bar. The swing spray arms on both sides and fixed top nozzles form a full-coverage spray network.

All nozzles are made of tungsten carbide, featuring anti-blocking and anti-abrasion performance, and will not be clogged by fine cement particles.

(3) Microwave Sensing & Central Control System

Adopts industrial microwave radar sensors, which are not affected by dust, strong light and fog. The core PLC + color HMI touch panel supports cycle time, water pressure and spray range adjustment.

Built with overpressure, water shortage and pump idling protection to prevent equipment damage. It can be connected to the plant’s central control system for unified management.

(4) Multi-stage Recirculating Water & Sludge Treatment Module

Consists of primary sedimentation zone, secondary filtration zone and automatic mud scraper. The integrated structure occupies less space.

The mud scraper regularly discharges settled cement sludge, and the water recycling rate reaches over 92%, realizing near-zero wastewater discharge. Matched with anti-scaling HDPE pipelines.

(5) Safety & Auxiliary Components

Equipped with warning lights, sound alarms and anti-collision guardrails to remind drivers and avoid vehicle collision.

Optional rainproof canopy and dust suppression covers for outdoor sites. All electrical parts reach IP65 waterproof and dustproof grade.

Standout Performance & Technical Advantages

(1) Dual-mode Flexible Operation: Switch freely between fast drive-through cleaning and deep fixed-point cleaning to match peak vehicle flow and heavy dirt conditions.

(2) Super Anti-clogging & Decontamination Capacity: Tungsten carbide nozzles + graded filtration system fundamentally solve the clogging problem caused by cement mortar, a common pain point of traditional washers.

(3) High Safety & Low Labor Risk: Drivers finish cleaning without getting off the truck, eliminating falls and slipping hazards during manual hopper cleaning.

(4) Excellent Water-saving & Eco-friendly Effect: The closed recycling system drastically reduces fresh water usage, fully meeting environmental assessment requirements in urban and desert areas.

(5) Strong Environmental Adaptability: Support -10℃ to +55℃ wide temperature operation, stable in Middle East high temperature, Southeast Asia humidity and northern low-temperature environments.

(6) Modular Quick Installation: Split structure enables on-site assembly within 1 working day, no large-scale civil transformation required.

(7) Low Vibration & Low Noise: Optimized pump damping structure, operating noise lower than 75dB, compliant with urban noise standards.

Comprehensive Customer Q&A

Q1: Can the microwave sensor work normally in dusty concrete plants?

A: Yes. Different from infrared sensors, microwave radar is not affected by dust, smoke and strong outdoor light. It maintains stable identification accuracy for a long time in high-dust mixing plant environments.

Q2: Is the nozzle easy to be blocked by cement and fine sand?

A: All spray nozzles are made of tungsten carbide with special anti-blocking holes. Meanwhile, the front-end multi-stage filter intercepts large particles, which effectively avoids clogging. Regular simple cleaning can keep the nozzles unobstructed.

Q3: Can the equipment operate normally in low-temperature areas?

A: The standard model adapts to -10℃ ~ +55℃. We can also configure electric heating components for ultra-low temperature areas below -10℃ to prevent pipeline water freezing.

Q4: What is the daily water consumption?

A: Relying on the 92%+ water recycling rate, the supplementary fresh water per vehicle is very little, which can save more than 80% water compared with direct flushing.

Q5: Does it support 380V 60Hz power supply for the Middle East?

A: All electrical components support 380V/50Hz and 380V/60Hz dual standards, and are optimized for generator power supply, adapting to the power conditions of Saudi Arabia, UAE and other regions.

Q6: Can I view the washing quantity and equipment status remotely?

A: Yes. The optional remote monitoring module supports real-time viewing of operating data, vehicle counting and fault alarm via mobile phones or computers.
