concrete batching mixing plant set when engaged in professional production, because of its greater intensity of production, it is difficult enough to be some prejudice can not imagine, today told this handling.
We all know, as this has a large mechanical repair curing period, the concrete mixer repair cycle we know? Construction workers is sure to understand, which is directly related to the safety of construction workers, and therefore this issue should be taken seriously, not the effect, here we come to introduce concrete mixer repair cycle, for we see.
Usually concrete mixer repair cycle is divided into four, namely, a security, two security, repair and overhaul some of these four.
A security patch cycle square concrete mixer is based on the amount of concrete stirring or based on the use of time is to determine the general concrete mixer stirring 5,000 cubic meters of concrete conservation should be repaired, or is the use of time in two months or so, They are to repair conservation.
The first patch cycle back to calculate the second patch cycle is beginning, and all for the second period than the first patch fixes a longer period. So how two security patch cycle count it? 10,000 cubic meters of concrete mixer to mix concrete or work four months after Paul II should enter a period, concrete mixing cycle will be longer and longer follow the idea came before a patch cycle than the next patch cycle longer.
The third patch cycle, also is in the repair time is stirred for 50 000 cubic meters of concrete mixer concrete should be entered in the repair. After all, is a long overhaul, overhaul cycle than doubled in the period of repair, also is mixing concrete 100,000 cubic midnight to start preparing for an overhaul. Here particularly explain, repair and overhaul cycle must control, assuming control of the less good, which directly affect the service life of concrete mixers, there will be serious trouble in the construction process, so the person in charge must to pay attention to it.

Before the construction of concrete mixing station equipment, power consumption costs we would normally do budget, calculate the investment return rate of mixing station. The method generally Budget concrete mixing station equipment is to consumption stirred host motor power, concrete batching system motor power, motor power screw conveyor system, electric control system electrical power obtained by adding together the entire mixing station equipment consumption per hour power.
Here we look at some of the common concrete mixing equipment power consumption per hour number, as follows:
HZS25 mixing station equipment power consumption per hour ≈46.1kw.H
HZS35 concrete batching plant power consumption per hour ≈60kw.H
HZS50 concrete mixing plant power consumption per hour ≈95kw.H
HZS60 concrete batch plant power consumption per hour ≈110kw.H
HZS75 concrete mixing equipment power consumption per hour ≈110kw.H
HZS120 concrete mixing station equipment power consumption per hour ≈200kw.H
HZS180 batching plant equipment power consumption per hour ≈260kw.H
The above model HZS concrete mixing station equipment according to different configuration, power consumption per hour is not the same.
On the engineering concrete mixing station Depending on the application, not the same concrete mix gravel, etc., but the process is the same production line. Concrete mixing station equipment consists of several parts, namely, control systems, batching system, material storage system, mixing system, weighing system components, production processes:
First, the sand and gravel by forklifts to shovel gravel as automatic batching machine proportioning weighing, conveyor belt through the ingredients to enhance the mixing console in the trunk (concrete mixing stations Suppliers by belt conveyor for aggregate into waiting hopper, waiting to enter the mixing console), ascends into compulsory mixer wait stirred tank;
