The Main Parameters of 1 Yard Concrete Mixer
Jul 01, 2020
During the purchase of 1 yard concrete mixer, we mainly pay attention to is parameter. Then what are the main parameters of the concrete mixer used?
1. Rated capacity
Feeding capacity refers to the volume of dry material that is loaded into the mixing drum without mixing.
The discharge capacity is the main performance index of the mixer, which determines the productivity of the mixer and is an important basis for selecting the mixer. 1 yard concrete mixer refers to that the output is 1 yard(about 0.76 m3).
2. Working circle
Feeding time. The time from the start of the hopper lifting to the complete discharge of the mixed dry material into the mixing drum.
Discharging time. The time taken for the concrete mixture not less than 90% (for rotary mixer) or 93% (for twin shaft mixer) of the nominal capacity to be discharged from the mixing drum.
Mixing time. The time is from the entrance of mixed dry material to the the finish of homogeneous concrete. It is about 35s-45s. For the 1 yard mixer, the mixing time is about 40s.
3. Mixing speed
The mixing speed is the rotating speed of the mixing drum, of which the unit is r/min. The rotation speed of twin shaft concrete mixer is generally 20~36r/min.
4. Productivity
The productivity of the 1 yard concrete mixer for sale is determined by the time required to prepare 1 batch of concrete and the discharge volume of one batch. The calculation formula is as follows:
Q＝3600V1ψ1/(t1＋t2＋t3)
Where Q- productivity, m3/h;
V1- feeding capacity, m3;
t1- Each feeding time, s;
t2- Each mixing time, s;
t3- Each discharge time, s;
ψ1—Discharge coefficient.
It is generally 0.65～0.7 for concrete and 0.85～0.95 for mortar.
