A mobile grouting trolley that automatically mixes, measures and delivers mortar/cement slurry. It combines an automatic feeding system, precision weighing, PLC-based microcomputer control, high- and low-speed mixing, water supply and a walking system for continuous grouting on construction sites.
Automatic screw feeding system, automatic weighing system, microcomputer/PLC control system (with memory), high-speed mixing drum, low-speed storage drum, water supply system and a walking/dragging frame.
High-speed mixing batch capacity is 350 kg. When manually controlled, the machine can produce approximately 4,000–7,000 kg of slurry per hour. The low-speed storage barrel holds 400 kg to enable continuous feeding.
High-speed agitator: 1430 r/min with a 7.5 kW motor. Low-speed (storage) agitator: 45 r/min with a 2.2 kW motor. Automatic charging uses two screw conveyors, each powered by a 1.5 kW motor.
The microcomputer automatic control system offers accurate measurement to two decimal places with measuring accuracy better than ±1% of the rated mixing volume. The system includes memory functions for repeatable mixes.
The machine uses a screw conveying automatic charging system (two 1.5 kW screw conveyors) to feed raw material into the mixer reliably and consistently.
Overall dimensions: 2800 × 1450 × 2200 mm (L × W × H). Total weight: 887 kg. Dragging (travel) speed is less than 20 km/h, making it suitable for site mobility. For transport on public roads, follow local regulations.
The machine uses the Liuzhou automatic grouting control system — a PLC/microcomputer-based controller providing automatic and manual operation modes, memory of mix recipes and precision weighing control.
Used in building construction, bridge construction and other civil engineering projects requiring grout, mortar or cement slurry application and continuous grouting operations.
The specification lists individual motor powers (high-speed 7.5 kW, low-speed 2.2 kW, charging 2 × 1.5 kW). Exact site power voltage, phase and total supply configuration should be confirmed with the supplier or in the machine's technical manual.
Place the trolley on a stable, level surface; secure power and water connections; check and connect the screw conveyors and motors; calibrate the weighing system per the manual; run initial no-load and trial mixes to verify settings. Installation and commissioning should be done by trained personnel or authorized technicians.
Daily cleaning of mixing drums and conveyors after use, inspect and tighten fasteners, lubricate bearings and moving parts as recommended, check seals and wear parts (agitator blades, screws), verify sensor and weighing accuracy periodically, and schedule motor/electrical inspections per the manual.
The machine is controlled by a PLC with automatic control functions. Operators should follow the supplier's safety manual, use required PPE, and rely on built-in safety interlocks/emergency stop functions if provided. Confirm specific safety devices and certifications with the manufacturer.
Common spares include agitator blades, screw conveyor augers, seals, wear liners, sensors and electrical/PLC components. Obtain genuine parts and service from the manufacturer or authorized dealers to ensure fit and performance.
Training, warranty terms and after-sales service vary by supplier. Contact the manufacturer or your equipment provider for details on operator training, commissioning support and warranty coverage.
