It is an important way to improve the efficiency of concrete mixer equipment to choose the right machine and use the mixer correctly according to the engineering requirements.
1
Select according to project quantity and time limit
When the concrete project is large and the construction period is long, it is advisable to choose medium or large fixed concrete mixer or mixing plant. If concrete project quantity is small and time limit is short, appropriate chooses small and medium-sized mobile mixer.
2
Choose according to the type of concrete designed
When the concrete mixing is plastic or semi-plastic, it is advisable to use self-falling mixer. It is simple in structure and easy in maintenance. Compared with the forced type, the stirring effect is a little worse. If mixing concrete for high strength, dry hard or lightweight concrete, it is appropriate to choose the forced mixer. It is more complex structure, high maintenance requirements, but good mixing effect, high efficiency.
3
Choose according to the composition and consistency of concrete
Such as mixing concrete consistency is small and the aggregate size is large, it is appropriate to choose a large capacity of the falling mixer. For concrete with large mixing consistency and large aggregate size, it is advisable to choose a mixer with a faster rotating speed. If the consistency is large and the aggregate size is small or mainly used in the mixing of light aggregate or hard aggregate concrete, it is appropriate to choose the forced mixer. Generally, high strength grade, high demand for the state of concrete, large consumption, all need to use the forced mixer.
It will greatly improve the working efficiency of the mixer if you choose the mixer correctly and do the following things in the process of using:
1
Good lubrication
Before working every day, the concrete mixer shall check the oil and the circuit and control equipment at each lubrication point, and fill the lubricating oil as required. However, there are a lot of local lubricants for the mixer, the method and amount of lubricant are not the same, and sometimes it is necessary to change a new lubricant.
2
Do a good job of cleaning
The concrete mixer must keep the mixer body clean and remove dirt and obstacles, especially foreign matters between the mixer blades or side blades and the inner wall of the tank.
3
Do a good job of checking
(1) before daily work must check whether the transmission clutch and brake is flexible and reliable, whether the wire rope is damaged, whether the track pulley is good, there are barrier-free around and various parts of the lubrication, etc.;
(2) the mixer must implement two levels of leakage protection, before going to work, the power supply is connected, must be carefully checked, after the empty car test is considered qualified, can be used;
Before the concrete mixer works every day, add water to the mixing drum and run it for 1 to 2 seconds. At the same time, check the reliability of the clutch and brake device.
