How do you control the rotational speed of a small concrete mixer? Let’s find out with the concrete mixer manufacturer!

　　Concrete Mixer Manufacturer: How to Control the Rotational Speed of Small Concrete Mixers

　　The concrete mixer truck manufacturer has learned that small- and medium-sized concrete mixers consist of an automotive chassis and a top cover. However, due to the wide variety of materials being loaded, it’s essential to ensure that the loading platform can rotate smoothly to prevent the concrete from setting prematurely and to achieve more uniform mixing. This rotation causes the material-holding tank to develop a velocity component that deviates from the direction of the vehicle’s towing hitch at the front. As the tank rotates, the upper part of the vehicle tends to sag slightly, making small- and medium-sized concrete mixers more prone to tipping over than other types of vehicles. That’s precisely why safety guidelines specify a maximum safe speed for these trucks: because of this deviation, the truck’s center of gravity is not fixed. When the vehicle speeds up too rapidly, the inertia forces prevent the small- and medium-sized concrete mixer from immediately adjusting its posture to maintain stability, which can lead to the vehicle tipping over and causing serious accidents.

　　Let’s hear from the concrete mixer truck manufacturer about the principle behind the mixing drum of concrete mixer trucks.

　　1. The brand-new concrete mixer truck features a unified structure, achieving homogeneity at both the macro and micro levels.

　　2. The mixer breaks up the agglomeration of cement particles, wetting the surface of each particle with water and thereby promoting the development of dispersion.

　　3. Break the initial hydration film coating on the surface of cement particles, thereby promoting the bonding between cement particles and other material particles and forming ideal hydration products.

　　4. Since the material surfaces are often covered with a thin layer of dust and clay, which hinders the formation of an interfacial bonding layer, the material particles must undergo repeated collisions and friction to reduce the impact of this dust film.

　　Next, let’s talk about the maintenance of hydraulic systems in concrete mixer trucks at the concrete mixer truck manufacturer.

　　Hydraulic System Maintenance Details for Concrete Mixer Trucks: Before a small concrete mixer truck arrives at the construction site and begins unloading, the mixing drum should rotate 10 to 14 times per minute. Then, reverse rotation should be initiated for unloading; prior to reversing, the mixing drum must be stopped first.

　　1. The hydraulic system of the concrete mixer truck shall comply with the specifications in the instruction manual and must not be adjusted arbitrarily. The quality and quantity of the hydraulic oil must meet the original requirements.

　　2. Before loading the concrete mixer truck, the residual water and debris inside the mixing drum should be cleared. During transportation, the drum must remain rotating to prevent segregation of the concrete.

　　3. When the ambient temperature exceeds 25 degrees Celsius, the duration from loading, through transportation, to unloading must not exceed 60 minutes. When the ambient temperature is below 25 degrees Celsius, the above-mentioned duration must not exceed 90 minutes.

　　4. During winter construction, concrete mixer trucks must be thoroughly checked before starting up to ensure there is no ice buildup. After work, carefully remove any residual water from the mixing drum and the water supply system, turn off the pump switch, and set the control handle to the “Stop” position.

　　5. After unloading concrete at the construction site, the concrete mixer truck should immediately use its built-in hose to flush the feed hopper, discharge hopper, and discharge chute, thereby removing any mud and concrete that has adhered to the truck’s body.
