SINOTRUK HOWO 350HP 8x4 On-Site Mixed Explosive Truck

The SINOTRUK HOWO On-Site Mixed Explosive Truck is a sophisticated mobile manufacturing unit that combines bulk material transport, precise mixing, and high-performance pumping into a single integrated system. Built on the proven HOWO TX 8×4 heavy-duty chassis, this vehicle is engineered to navigate the challenging terrain of open-pit mines and quarry operations while delivering consistent, high-quality emulsion explosives directly into boreholes. The vehicle utilizes an end-sensitization process, where emulsion matrix and additives are transported separately and mixed at the point of delivery, ensuring optimal stability during transport and maximum performance at the moment of use.

At the heart of the system is a PLC-based PID closed-loop control system that continuously monitors and adjusts the mixing process, maintaining dosing accuracy within ±1% tolerance. This precision ensures that the final explosive formulation meets exact specifications, delivering consistent blasting results that optimize fragmentation and reduce secondary blasting requirements. The control system integrates flowmeters, speed sensors, and pump motor controls to regulate the flow of emulsion matrix, sensitizers, and additives, with real-time adjustments based on process conditions.

Key Features:

· SINOTRUK HOWO TX 8×4 Heavy-Duty Chassis: Powered by a 350HP engine with a robust 8×4 drive configuration, this chassis delivers exceptional off-road capability for navigating steep grades, loose surfaces, and uneven terrain typical of mining operations. The chassis is equipped with ABS anti-lock braking, rear air suspension, remote central locking, and a heavy-duty air cleaner system designed for dusty environments. The cab features a suspension seat with adjustable height for operator comfort during extended shifts, and AdBlue compatibility ensures compliance with emissions standards.

· PLC-Based PID Closed-Loop Control System: The advanced control system maintains mixing tolerances within ±1%, ensuring precise explosive quality batch after batch. The system integrates flowmeters, speed sensors, and pump motor controls to regulate the flow of emulsion matrix, sensitizers, and additives. PID closed-loop control continuously adjusts pump motor speeds based on real-time process feedback, maintaining accurate dosing regardless of variations in material viscosity or flow conditions. The HMI interface allows operators to adjust process ratios instantly to match specific rock characteristics observed on site.

· 360° Rotating Hose Guide Boom with Automatic Hose Management: The automatic hose handling system significantly reduces labor intensity and improves operational efficiency. Comprising a turntable, reel, and telescopic boom with a 2.3-meter operating radius, the system enables multi-directional loading from a single vehicle position. Automatic hose extension and retraction functions allow a single operator to control all aspects of the hole-filling process, reducing crew size requirements while maintaining safety and precision.

· Special Droplet-Shaped Tank Construction: The emulsion matrix tank features a water-drop shaped design that optimizes material flow and minimizes residual product. Constructed from 304 stainless steel with 50mm flame-retardant polyurethane insulation, the tank maintains stable material temperatures across a wide range of ambient conditions. The tank is engineered with enhanced structural strength and rigidity to withstand the torsional stresses of off-road operation, while corrosion-resistant and fire-retardant properties ensure long-term durability in harsh mining environments.

· Special Water Ring Drag Reduction System: This innovative system creates a water ring between the pump and delivery hose, significantly reducing friction resistance during pumping. This technology enables the long-distance delivery of high-viscosity emulsion over distances of 80 meters or more, with delivery pressures maintained between 0.5 and 0.8 MPa. The reduced pressure requirements allow for smaller-diameter hoses and lower power consumption while maintaining flow rates sufficient for efficient borehole filling.

· End-Sensitization Process Flow: The vehicle employs endpoint sensitization, where emulsion matrix and additives are transported separately and mixed only at the point of delivery. This process ensures that the explosive remains in a stable, non-explosive state during transport and storage, with sensitization occurring only when the materials are combined in the borehole. A static mixer ensures final blending, forming high-performance explosive with consistent properties throughout the borehole column.

· Comprehensive Safety Systems: The vehicle is equipped with multiple safety features including advanced safety interlocks that prevent operation when conditions are unsafe, pressure sensors that monitor system integrity, and an anti-static rear working platform. Emergency cut-off valves are positioned on each side of the vehicle for rapid response, while explosion-proof electrical components and warning lights ensure safe operation in hazardous environments. The tank top features an anti-skid stainless steel walkway with guardrails, providing safe access for inspection and maintenance.

· Manual-Auto Integrated Control: The hydraulic system features dual-mode control with both automatic and manual operation capabilities. High-precision hydraulic flow control ensures robust reliability and stability during normal operation, while an emergency manual override system provides fail-safe operation in the event of control system issues. This redundancy ensures seamless task continuity and operator confidence in all conditions.

Application:

· Open-Pit Mining: Ideal for large-scale surface mining operations requiring precise, consistent blasting results for ore fragmentation in copper, gold, iron ore, coal, and other mineral extraction operations.

· Quarry Operations: Suitable for aggregate and dimension stone quarries where controlled blasting is essential for product quality and operational efficiency.

· Civil Construction: Applicable for large infrastructure projects requiring rock excavation, including road construction, tunnel boring, and dam foundation work.

· Underground Mining: Adaptable for underground operations where precise explosive placement and remote operation capabilities enhance safety.
