Professional Mixer Truck Washing Machine Manufacturer

As a manufacturer and supplier in China, SINOU's Fully Automatic Mixer Truck Washing Machine is a dedicated high-pressure cleaning device tailor-made for ready-mix concrete mixer trucks and various heavy engineering vehicles. Different from ordinary civilian car wash equipment, it adopts touchless high-pressure spray technology and load-bearing reinforced structure, targeting thick cement slurry, sticky mud and dust attached to mixer truck tires, chassis, mixing drum and feed hopper.

Equipped with an integrated circulating water treatment system, this machine realizes water recycling and zero sewage discharge. It supports automatic induction startup, full-range dead-angle cleaning and fast cycle operation. It is an essential environmental protection and efficiency-improving device for concrete batching plants, construction yards, mining areas and large vehicle fleets.

Our products have been widely exported to the Middle East, Europe, Southeast Asia and other regions, and have passed multiple international certifications. They are well received by customers for stable performance, water-saving and environmental protection, and low failure rate.

How It Works & Operational Process

This mixer truck washing machine adopts infrared induction + PLC intelligent control, combined with multi-angle high-pressure spray and circulating water filtration technology. The full automatic working cycle is as follows:

(1) Vehicle Sensing & Startup: When the mixer truck drives into the designated washing area, the infrared sensor automatically identifies the vehicle and triggers the whole system to start. The driver does not need to get off the truck.

(2) 360° High-Pressure Cleaning: Multi-directional nozzles on both sides, bottom and top spray high-pressure water jets simultaneously. The high-speed water flow strips cement dirt, mud and dust from the tires, chassis, car body and mixing drum.

(3) Sewage Collection & Recirculation: The washed sewage flows into the underground sedimentation tank and multi-stage filter device. After removing mud and sundries, the clean water is pumped back to the high-pressure water pump for recycling.

(4) Auto Shutdown & Reset: After the preset cleaning duration ends, the spray system stops automatically. The vehicle drives away, and the whole machine returns to the standby state, waiting for the next vehicle.

(5) The whole process is unmanned, with a single cleaning cycle controlled within 60–90 seconds, which greatly improves the vehicle passing efficiency of the mixing plant.

Build & Component Details

(1) Reinforced Bearing Base & Main Frame

The load-bearing base is made of thickened national standard steel plate + reinforced I-beam, with overall anti-rust treatment. The standard load capacity reaches 80–120 tons, which can fully adapt to fully loaded mixer trucks.

The overall frame adopts welded structure with high rigidity, no deformation after long-term rolling of heavy vehicles. The outer shell is made of corrosion-resistant steel plate, suitable for outdoor long-term wind and rain exposure.

(2) High-Pressure Water Supply & Spray Assembly

Equipped with industrial-grade high-pressure water pump group, the stable water pressure is maintained at 100–120 bar. The whole machine is equipped with dozens of directional spray nozzles, which are scientifically arranged around, bottom and top to form a three-dimensional spray network.

The nozzles are made of wear-resistant alloy, not easy to block, and can clean the tire tread, chassis gap and mixing drum without dead angles.

(3) Sensing & Intelligent Control Unit

Adopts high-sensitivity infrared radar sensor, with strong anti-interference ability, not affected by light and dust. The core control part is a dedicated PLC controller + touch panel. Users can freely set cleaning time, water pressure and spray mode.

It has built-in functions such as overload protection, pump dry-running protection and fault self-alarm, which ensures safe operation. It can also be connected to the factory central control system for remote monitoring.

(4) Recirculating Water & Sludge Removal Unit

Matching multi-stage sedimentation tank and automatic mud scraper. The sewage generated by cleaning is filtered and precipitated layer by layer. The sludge is regularly discharged by the mud removal device, and the clean water is recycled.

The water recycling rate is over 90%, which saves a lot of tap water. The pipeline is made of high-pressure resistant HDPE pipe, which is anti-corrosion and anti-scaling.

(5) Splash Guard & Enclosure System

Optional fully enclosed splash-proof enclosure to prevent high-pressure water and mud from splashing around, keep the site clean and meet local environmental inspection requirements. The enclosure is equipped with quick-assembly structure, easy to disassemble and transport.
