What is the delivery time requirement of concrete mixer for ready mixed concrete? The following editor will explain it to you.
Any ready mixed concrete will enter the initial setting state in about 1 hour without adding retarder. At this time, the concrete pouring will affect the quality of the concrete. Therefore, the transportation of ready mixed concrete by mixer truck has its time controlled transportation radius requirements. Generally controlled within 1 hour.
The long time from the feeding of commercial ready mixed concrete to the completion of unloading is 90 minutes, and the total number of revolutions of the mixing drum is not more than 300. If the original discharge chute is not long enough and needs to be lengthened, please support the lengthened part with a pillar.
After the concrete is discharged, the inside of the mixing drum shall be washed quickly. Note: if not washed in time, it will not only cause the concrete in the mixing drum to bond, reduce the loading capacity, and obstruct the feeding, but also bring failure to the mechanism, which is one of the inducing factors of the accident. Be careful!
When the truck is running empty, the mixing drum shall rotate at the same stirring speed as when the truck is loaded.
If the full load concrete needs to be reversed when it is rotating forward, it needs to control the handle to make it forward and stable, and then reverse it. When the forward rotation is no longer possible, control the handle to reverse it.
The continuous time of the working device of the concrete mixer shall not exceed eight hours.
When the vehicle is in the no-load driving process, the mixing drum cannot stop running, so as to avoid the collision of the tug and the raceway caused by the bumping during the driving process and the abnormal damage.
The capacity, quality and slump of concrete transported by the concrete mixer must meet the requirements and standards of the concrete industry.
Note: when the mixer truck is running, if the mixing stops rotating, there will be indentation on the mixing drum raceway and the mixing drum supporting wheel, and abnormal noise will occur. Therefore, please be careful. For more information, please visit our website Consult.
