Twin Shaft Concrete Mixing Pump
The twin-shaft concrete mixing pump is a mechanical equipment that integrates concrete mixing and conveying functions. It is widely used in construction, bridge construction, road paving and other projects. It can mix cement, sand, gravel, water and other raw materials into concrete in a certain proportion, and convey the mixed concrete to the designated location through the pumping system, so as to achieve continuous and efficient concrete production and delivery.
Capacity：40m³/h
Warranty: 18 months
Power: 45-129kw
Voltage: 220v/380v/415v/440v/480v(50Hz/60Hz)
Product Structure
The twin-shaft concrete mixing pump is mainly composed of the following parts:
Mixing system:
Mixing drum: used to contain and mix concrete, usually a twin-shaft structure, with a wear-resistant lining inside.
Twin-shaft mixing device: includes two parallel mixing shafts, with mixing blades installed on the shafts, which rotate synchronously through a gear or chain transmission system to ensure uniform mixing of concrete.
Conveying system:
Concrete pump: includes pumping cylinder, piston, distribution valve and other components, driven by a hydraulic system to convey the mixed concrete to the designated location.
Conveying pipeline: used to convey concrete, usually made of high-strength and wear-resistant materials.
Power system:
Engine or motor: provides power, usually a diesel engine or motor.
Hydraulic system: provides power for the pumping system, including hydraulic pumps, hydraulic oil tanks, control valves, etc.
Control system:
Control panel: used to control the start, stop, speed adjustment and other operations of the mixing and pumping process, usually electronically or hydraulically controlled.
Sensors and instruments: used to monitor various parameters in the mixing and pumping process, such as temperature, pressure, flow, etc.
Working principle
Raw materials (cement, sand, gravel, water, etc.) enter the mixing drum through the feeding device. The twin-shaft mixing device starts to rotate, and the mixing blades fully mix the raw materials to form uniform concrete. The mixed concrete is continuously stirred in the mixing drum to ensure its uniformity and fluidity. The mixed concrete enters the pumping cylinder through the delivery pipe. The hydraulic system drives the piston to reciprocate and pushes the concrete into the distribution valve. The distribution valve distributes the concrete into the delivery pipe and transports it to the designated location through the pipe.
Product Advantages
High efficiency: The twin-shaft mixing device can achieve fast and uniform mixing, shorten the mixing time, and improve production efficiency. It integrates mixing and pumping, reduces equipment conversion and transportation time, and improves construction efficiency.
Uniformity: The twin-shaft mixing device can ensure the uniformity of concrete, avoid concrete segregation, and improve concrete quality.
Flexibility: The equipment is small in size and easy to move, suitable for various construction sites. The speed and capacity of mixing and pumping can be adjusted as needed to meet the needs of different projects.
Reliability: Made of high-strength and wear-resistant materials, the equipment has a long service life. Equipped with advanced control systems and sensors, it can monitor and adjust the mixing and pumping process in real time to ensure stable operation of the equipment.
Environmental protection: The equipment has good sealing performance, low dust and noise pollution, and meets environmental protection requirements.
Equipped with dust removal and noise reduction devices to further reduce the impact on the environment.
