Diesel Engine Twin Shaft Concrete Mixer
The diesel engine twin-shaft concrete mixer is a concrete mixing equipment that uses a diesel engine as a power source. It is widely used in construction sites, road construction, bridge projects and other places where concrete mixing is required. It is especially suitable for environments with inconvenient or unstable power supply. The equipment uses two parallel horizontal mixing shafts for mixing, which can quickly and evenly mix various concrete materials. It has the characteristics of strong structure, flexible operation and high production efficiency.
Capacity：25-150m³/h

Product Structure
Mixing device:
Twin shafts: two parallel mixing shafts with mixing blades on them. The blades are arranged in a spiral shape, which can fully mix the concrete materials.
Mixing blades: installed on the mixing shaft, usually made of wear-resistant materials to ensure that the mixing effect can be maintained after long-term use.
Power system:
Diesel engine: provides power, usually a four-stroke or two-stroke diesel engine, with the characteristics of fast start-up and strong power.
Transmission: The power of the diesel engine is transmitted to the mixing shaft, usually by belt drive or gear drive.
Frame and shell:
Frame: The structure that supports the entire mixer, usually welded from high-strength steel, with good rigidity and stability.
Shell: Wraps the mixing device and power system, usually made of wear-resistant steel plates, with lining plates inside to prevent wear.
Feed and discharge system:
Feed port: used to add concrete materials into the mixer, usually with a feed hopper and a feed gate.
Discharge port: used to discharge the mixed concrete, usually equipped with a discharge gate and a conveying device.
Control system:
Control panel: used to control the start, stop, speed adjustment and other operations of the mixer, usually equipped with various indicator lights and buttons.
Sensor: monitors the operating status of the mixer, such as temperature, pressure, speed, etc., to ensure the safe operation of the equipment.
Cooling system:
Radiator: used to cool the diesel engine, usually using air cooling or water cooling.
Fan: assists the radiator for cooling to ensure that the diesel engine works normally under high temperature environment.
Working principle
Start the diesel engine to provide power. Concrete material enters the mixer through the feed port. The diesel engine drives the mixing shaft to rotate through the transmission device, and the mixing blade pushes the concrete material to the middle of the mixing shaft. At the same time, shearing, extrusion and flipping are carried out to achieve full mixing of the materials. The mixed concrete is discharged through the discharge port and transported to the construction site.
Product Advantages
Strong power: The diesel engine provides powerful power to meet the needs of high-intensity mixing. It starts quickly and adapts to various complex working conditions.
Strong adaptability: It does not rely on power supply, and is particularly suitable for environments with inconvenient power supply or unstable power supply. It can work normally under harsh environmental conditions, such as high temperature, low temperature, humidity, etc.
Efficient mixing: The double-horizontal shaft design makes the mixing more uniform, the mixing time is short, and the production efficiency is high. The mixing blades are arranged in a spiral shape, which can effectively prevent material accumulation and ensure the mixing quality.
Strong structure: The overall structural design is strong and can withstand a large workload. The key components are made of high-strength materials and have a long service life.
Flexible operation: The control panel is simple in design, easy to operate and easy to master. There are a variety of safety protection devices to ensure the safe operation of the equipment.
Convenient maintenance: The equipment is reasonably designed and easy to disassemble and repair. The key components are modularly designed and easy to replace.
Energy saving and environmental protection: The diesel engine adopts advanced combustion technology, low emissions, and meets environmental protection standards. It is equipped with an exhaust gas treatment device to reduce the impact on the environment.
