Equipment OverviewA concrete mixer pump is an advanced engineering machine that integrates concrete mixing and high-pressure pumping functions. Its core design concept is to achieve fully automated operations from raw material mixing to long-distance pumping through an integrated system, which is especially suitable for small and medium-sized construction projects, such as residential buildings, bridges, and municipal engineering.Taking the 40m³/h processing capacity model as an example, the equipment uses a self-falling mixing barrel. Based on the principle of gravity mixing, it can efficiently complete concrete mixing, and combined with a high-pressure pumping system, it can produce and pump 40 cubic meters of concrete per hour. It has both high efficiency and reliability, and has become a cost-effective solution in the international market.Detailed explanation of the working principleThe working process of the concrete mixer pump is divided into three modules: mixing system, pumping system, and intelligent control system. These modules work together to ensure efficient mixing and precise pumping of concrete.(1) Mixing system (self-falling mixing drum)Self-falling mixing principle: The mixing drum rotates through the drum (speed 4-8r/min), lifts cement, aggregate, water and admixture to a certain height, and then falls freely by gravity to evenly mix all raw materials.Low energy consumption design: Compared with the forced mixer, the self-falling mixing drum reduces mechanical friction and improves energy efficiency by 20%-30% (motor power is 15-22kW).Large-capacity feed port: It has a wide feed port to support rapid feeding, and with the inclined drum structure, it ensures that the mixing time is ≤90 seconds/batch, meeting the continuous discharge requirement of 40m³/h.Wear-resistant lining: The inner wall of the drum uses a high-manganese steel lining to extend the service life of the equipment (>50,000 mixing cycles).(2) Pumping systemHydraulically driven piston pump: The delivery piston is pushed by the high-pressure hydraulic cylinder to press the mixed concrete into the delivery pipeline.S-valve switching technology: The swing-type distribution valve (S-valve) is used to alternately switch the concrete cylinder and the delivery pipe channel to ensure continuous pumping (the outlet pressure can reach 10-15MPa).Intelligent lubrication system: Automatically spray lubricant on the inner wall of the delivery pipe to reduce friction resistance and extend the service life of the pipe.(3) Intelligent control systemPLC+human-machine interface: Real-time monitoring of key parameters such as mixing time, pumping pressure, drum speed, etc., supports one-key start and stop and fault diagnosis, and ensures the intelligent operation and high efficiency of the equipment.Core advantages of 40m³/h model(1) Efficiency and reliabilitySimplified structure: The self-falling mixing drum adopts a design without complex transmission components, and the failure rate is 40% lower than that of the forced mixer.Continuous operation capability: The mixing and pumping systems work together to complete 200-320m³ of concrete pouring tasks per day, ensuring efficient construction.(2) Cost savingsMaintenance cost: The replacement frequency of the wearing parts of the self-falling mixing drum is low, and the annual maintenance cost can save about $3,000.Power consumption: The mixing system has low power demand, and the overall energy consumption is reduced by 15%-20%.Labor cost: Fully automated operation requires only 2-3 people, which reduces labor input by 50% compared to the traditional model.(3) Material adaptabilityLarge aggregate compatibility: The self-falling mixing drum can handle coarse aggregate with a maximum particle size of 80mm, which is suitable for the production of high-strength concrete.Low-loss design: The closed mixing and pumping process is adopted, and the material waste rate is less than 1%, which improves material utilization.(4) Spatial flexibilityCompact layout: The equipment size is 9m×2.8m×3.2m, which is suitable for narrow construction sites. There is no need to pre-build a mixing station, which greatly saves construction site space.Pumping capacity: The horizontal pumping distance can reach 500m, and the vertical pumping height is 120m, which can meet the needs of multi-story buildings and tunnel construction.Environmental protection and sustainabilityLow noise operation: The self-falling mixing drum has no high-speed mixing blades, and the noise level is less than 70dB, which is significantly reduced compared to traditional forced mixers (about 80dB).Low carbon emissions: The improvement of energy efficiency directly reduces the carbon emissions of diesel generators or power grids.Long life design: The life of key components is increased by 30%, the frequency of equipment scrapping is reduced, and the generation of industrial waste is reduced.ConclusionThe 40m³/h concrete mixing pump with a self-falling mixing drum provides customers with cost-effective and stable construction solutions through gravity mixing optimization, low maintenance design and highly adaptable pumping technology. Its short payback period of 8 months, low operating costs and environmental performance make it an ideal choice for international infrastructure projects.If you need to adapt to different aggregate specifications or customize pumping pressure solutions, our engineering team can provide personalized optimization designs according to actual needs.
