When the small concrete mixer is driven normally and does not need remote accelerator, the remote accelerator switch must be turned off; After using the remote accelerator, please turn off the remote accelerator switch immediately to ensure the safety of the vehicle. We should understand such precautions. Let's talk about how to mix concrete with a concrete mixer.
How to mix concrete with concrete mixer? If concrete (wet mixing) is directly mixed with a mixer without the aid of a mixing station, please follow the following steps:
First inject 2 / 3 of the total water consumption;
Next, 1 / 2 of the coarse aggregate, 1 / 2 of the sand and all the cement are sent to the mixing drum in sequence, and then the remaining 1 / 2 of the sand is sent to the mixing drum;
After that, the remaining 1 / 2 of the coarse aggregate and 1 / 3 of the water are sent.
(2) Mixing drum speed and mixing time
Speed of mixing drum during feeding: 6-10 rpm
Speed of mixing drum during mixing: 6-10 rpm
Mixing time: 10-16 minutes after feeding
(3) Stirring and discharging
Stirring and discharging after mixing.
When feeding, do not only feed cement.
The above method is only one example. As the concrete mixing method varies with the concrete type, please determine the actual method and value according to the results of trial mixing.
In arid areas, when long-distance transportation of ready mixed concrete is required, in order to ensure the quality of concrete, the water is added and mixed after being transported to the destination, so the mixer must have a large capacity water tank to meet the requirements.
The concrete shall be added into the mixing drum to make the mixing drum rotate. The engine speed shall be controlled at 550-650r / min. Otherwise, when the engine is running at a low speed, it is easy to cause the engine to shut down and damage the clutch, bearing (clutch gearbox), etc. if the mixing cylinder with ready mixed concrete is operated.
Please note that there is a remote accelerator switch in the cab of the mixer. When the pedal accelerator in the cab works, the remote accelerator at the rear of the vehicle will be closed and will not work. At this time, if you want to control the accelerator with a handle at the rear of the vehicle, you need to press the remote accelerator switch.
