Portable diesel cement grout mixer
The HWM400D portable diesel cement grout mixer is equipped with a 10 Hp diesel engine operating at a rated speed of 2,200 rpm, which drives a high-speed impeller rotating at 1,500 rpm to prepare the grout within its 400-litre tank. There is no need to wait for temporary power to be connected on site, allowing for more flexible positioning close to boreholes, tunnel portals or foundation treatment areas.
At tunnel portals, mine galleries, dam abutments and remote foundation sites, a stable three-phase power supply is not always available at the grouting point. Portable diesel cement grout mixers can provide their own power supply, reducing the constraints associated with the deployment of temporary cables, transformers and generators. For teams that need to move between multiple boreholes or work fronts, this self-contained power configuration makes it easier to organise day-to-day construction operations.

Diesel power does not mean zero maintenance. Contractors must still arrange for fuel storage, routine maintenance, fire safety measures and exhaust emission control. When used in enclosed underground spaces, project regulations regarding ventilation, air quality and equipment emissions must be met; if on-site emission requirements are stringent, the electric version may be more suitable.
The HWM400D portable diesel cement grout mixer can mix cement, bentonite and slurries containing fine sand (subject to verification), and is suitable for hole filling, rock reinforcement, foundation treatment and slurry preparation for underground works.

This portable diesel cement grout mixer is suitable for tunnel and mine support, dam foundation maintenance, slope stabilisation, grouting for micro-piles and general ground improvement works. To obtain a precise solution, please provide the type of project, grout formulation, water-to-cement ratio, target pressure and flow rate; we can then recommend the most suitable grout tank and grouting pump.
