Concrete mixing plant can not operate irregularly
1), easy to damage the stability of the host, affecting the concrete mixing plant host security. The host has always been the core control part of the entire mixing station system, a minor modification to any of its parameters may affect the production of the entire mixing station. Serious illegal operation may cause host safety to be affected. There have been due to illegal operation of the cause of the entire concrete mixing plant host system paralyzed the phenomenon. Therefore, the Fulaier machinery to remind our customers, the host operation is very important, we must use professional and technical personnel in accordance with the relevant process reasonable and standardized operation, encountered special circumstances should also consult the professional staff or equipment manufacturers with the mixing station, and Do not be free to operate.
2), easy to damage the mixing station weighing system. To commercial concrete mixing plant, for example, the material and moisture weighing accuracy is very high, if non-professional staff free operation lead to important material and moisture does not meet the requirements, it is prone to heavy material caused by weighing system Damage, and material leakage damage to the weighing system of the phenomenon of the sensor, thus affecting the mix of the entire commodity concrete, and ultimately lead to the subsequent production of concrete products are not up to standard. Therefore, the Fulaier machinery recommended concrete mixing station weighing system operation must hire professional laboratory personnel to operate, not to arbitrarily change, adjust the data has been set up.
3), easily lead to stirring the host of the fault. For different nature, different weight, different mix of materials, mixing, mixing the host in some important parameter settings such as mixing time, stirring speed and other requirements are very different, if you arbitrarily change the parameters of these mixing host, there will be Stirring speed too fast lead to damage to the mixing shaft, stirring too long lead to damage caused by the phenomenon of agitation shaft. Therefore, the operation of the mixing console must ensure that the professional and technical personnel responsible.
4), easy to damage the stability of cement storage materials. For concrete products that have been produced for compliance, they need to be stored in different tons of bulk cement ware or sheet-like cement warehouses. But in the storage process must pay attention to the speed of the material, and the feed port, the discharge port is blocked, the top of the cement warehouse cleaning operations, etc., these are the need for professional staff to carry out the operation to complete , If the operation by the non-professionals at random, it is easy to appear in the mouth of the mouth, the top of the cement warehouse because of excessive damage to the concrete ash and other cement storage material stability of the phenomenon.

The working principle of concrete mixing plant
On how the concrete mixing plant is working, many people think that the relevant raw materials Tim to participate in concrete mixing plant, mixing with concrete mixing station used to complete.
The concrete used in the concrete mixing plant is a building material that is used on a global scale, its strength, durability, and low cost. Material, so that it is readily available. One of the specific drawbacks is that it is broadly that the concrete mix must be in the field or within a reasonable interval of a specific batch mixer. When the concrete is a mixture of cement, water, sand and gravel, the resulting material is reacted.
This wide range of building materials between the cement mixture and the water molecules is exothermic. The cement is made of damaged alumina, silica, lime, iron oxide, and magnesium oxide, which has been heated to the sintering temperature at which the surface tension is reduced and the particles are intertwined. Precision, product powder easy to react with the occurrence of water products. Mixed with the same, directly related to the quality of concrete products.
The concrete mixing station takes the water as a concrete to the concrete batch mixer, the cement is active as a paste, and finally the batter-like compound and a mixture of rocks, sand and gravel. The mixture, now called the concrete collaboration ratio, will set a reaction that is not reversible. In the process, once the water to participate, is not blocked until finished. The concrete is generally packed and poured into three to seven hours.

Concrete mixing plant leakage how to deal with
Concrete mixing plant as a production of concrete mixing equipment, is the road construction, construction of indispensable mixing equipment, its safe and smooth operation is related to the progress of the entire project and the safety of construction workers. But any kind of machinery and equipment in the course of the operation will inevitably encounter some unexpected events, including power, leakage, damage to parts and so on, for concrete mixing station such a large equipment, the leakage phenomenon has occurred , Once the problem, how to solve it?
1, to determine whether the line is really leakage.
You can use the megger to shake the size of the line insulation resistance, or in the total knife gate connected to a ammeter, without opening the equipment under the premise of all the mixing station equipment, if the ammeter pointer swing, then the line leakage.
2, to determine the phase line and zero line leakage or phase line and earth leakage, or both. If the ammeter indication is zero, it is between the phase line and the zero line leakage; if the ammeter indication becomes smaller but not zero, then the current meter indication is zero, Said both.
3, determine the leakage range.
Remove the split fuse or pull the knife, if the ammeter indicates the same, it is the bus leakage; if the ammeter indicates zero, it is shunt leakage; if the ammeter indication becomes smaller but not zero, then the bus, Road are leakage.
4, find the leakage point.
After the inspection of the above concrete mixing station line, and then opened the switch in turn the line lamps. When a switch is opened, if the ammeter indicates zero return, it is the branch line leakage, if the ammeter indication becomes smaller, then that in addition to the branch line leakage, there are other leakage. Or use the pencil test can also be used. In turn to narrow the scope of the search, you can find the leakage point.
