400L Heavy-Duty Electric Concrete Mixer (380V, 2.2kW) – Model S-TM400ET
Boost operational productivity and deliver consistent, homogeneous concrete batches on commercial construction sites with the 400L Heavy-Duty 3-Phase Electric Concrete Mixer (Model S-TM400ET). Driven by a powerful 2.2kW three-phase electric motor (380V), this high-capacity mixer generates up to 4.65 m³/h of output—making it the ideal continuous-duty solution for civil engineering contractors, industrial building projects, and pre-cast concrete facilities.
Key Features & Highlights
400 Litre High-Capacity Drum: Optimized for batch efficiency, achieving up to 15 mixing cycles per hour to keep large site crews supplied without delays.
Industrial 380V Three-Phase Power: Powered by a 2.2kW 380V electric motor designed for continuous commercial duty, driving smooth 30 RPM drum rotation (60Hz) via a durable "V" A-48 belt drive.
Heavy-Gauge Steel Construction: Manufactured with a robust 2mm thick steel drum plate and reinforced frame chassis to withstand high aggregate impact and long-term site wear.
Comprehensive Operator Safety: Includes full safety guarding, featuring a steel plate flywheel guard and complete ring gear protection to ensure compliance and operator safety.
Heavy-Duty Mobility: Fitted with 68mm solid rubber wheels for controlled transport, positioning, and firm stability on active job sites.

Safe Operating & Maintenance Guidelines
Safety Notice: Operating 380V heavy machinery requires strict adherence to site safety protocols and electrical safety regulations. Always wear appropriate personal protective equipment (PPE), including safety glasses, protective gloves, ear protection, and steel-toe boots.
Placement & Setup: Position the mixer on a flat, solid foundation. Block the wheels to prevent movement during operation.
Electrical Connection: Connect the machine exclusively to a certified, grounded 380V 3-phase power supply equipped with adequate circuit breaker protection.
Pre-Start Inspection: Check belt tension (A-48), verify all protective guards are locked in place, and ensure the drum interior is free of hardened concrete.
Operation Sequence: Start the motor with an empty drum. Add water, gravel, sand, and cement progressively while the drum is spinning to prevent motor strain.
Discharging: Turn the flywheel to tilt the drum safely and discharge mixed concrete directly into wheelbarrows or placement trays.
Cleaning & Maintenance: Immediately flush the drum interior with clean water after finishing mixing operations to prevent cement buildup on internal blades and walls.
