Installing concrete batch plant , after commissioning before the user ease of use.
In the debugging control system when the first emergency reset button, power on the electric cabinet open off sequentially closed after turning on each branch circuit breakers, control circuit power switch, power switch control room, electrical system, there is no query anomalies, if immediately checked.
Each motor turn button, try working rotation of the motor is not accurate, if not precisely be adjusted immediately.
Initiate conrete mixer with pump sequentially initiate each pneumatic door according button marked until the pressure reaches the request, checks the action is not active; for microcomputer zero degrees and transfer active; check the compressor switch is not normal, barometer flash is not exact, the pressure relief valve to adjust the standard plan; work on the shaker test, to see whether there abnormal sound, each member is not able to work; when the pair of modular concrete mixing plant commissioning work demands, work in process check each roller work is not active, careful inquiry should belt, there can be shaken, deviation, milling, slip, deformation, etc.
There are always special weather that users may meet, for example rainy and thunder days. Then how to prevent concrete mixer unnecessary harms from bad weather?
1. It is important to do heat dissipation work, such as, set the concrete mixer in the open air place or avoid insolate place.
2.Find something to cover concrete mixer in rainy and thunder days.
3. The water is easy to evaporate in hot summer, so it is necessary to clean the remaining concrete in mini mobile batching plant mixing drum to prevent the concrete from solidifying and avoid affecting the working performance of concrete mixer.
4. It is important to do rainproof work for the wire which connects with concrete mixer semi trailer and plug par.
The fllowing is three points of concrete mixing plant electric system :
1. When the concrete mixing plant is in the production, it is required that the whole working process of electric system of concrete mixing plant can be controlled automatically. That is to say, not too many administrative staff can finish the whole working process in the construction sites ofconcrete mixing plant.
2. When the measuring system of concrete mixing plant is set up with zero output, the electric system of concrete mixing plant can remove the tar weight automatically and correct the drop, which can effectively control the measuring accuracy. The concrete mixing plant must be equipped with lighting alarming device.
3. The electric system of batching plant manufacturer should be convenient to input and operate and can adjust and modify the setting value of each material accurately. The electric system of concrete mixing plant must be provided with perfect self-locking and interlocking functions, which can ensure the accurate and reliable operation of electric system. As for the commonly seen faults, electric system of concrete mixing plant must posses the functions of fault diagnosis and failure warning.
As for the years or professional operating personnel of concrete mixing plant, they all know that it is of great importance to guarantee the electric system of mobile concrete mixing can catch up with the working process during the operation of concrete mixing plant.
The specialty of the portable concrete batching plant is that they can be towed easily by a tractor.

Concrete batching plant is essential to building industry. With the development of real estate, the market demand for mobile concrete mixing is becoming more and more big. Therefore, now more and more machinery companies were founded.
Now let me introduceHAOMEI Mobile Concrete Batching Plant to you.
The main characteristics of the mobile concrete batching plant:
1.Fast dismantling and Convenient move
Except the joint equipment such as screw conveyor, cement bin, the concrete batching plant’s all wirings don’t need to be removed. When installation, if the ground is flat, the solid foundation will not be necessary and the production can be in place. It is very suitable for the firm that has a time limit for a project.
The portable concrete mixing plant is equipped with tire and traction pin. It allows the highest speed of sixty kms/hour. The mobile concrete batching plant weights 23.5 tons.
2. Good mixing performance
Twin shaft concrete mixer can use the shortest time to stir evenly stirring. For the harsh, half harsh, plastic and various kinds of proportion of concrete, the performance is the same with that.
3. Configuration of high-grade, high reliability, measurement precision and easy operating.
Believe correct and skillful operation will help you improve concrete mixer work efficiency.
Just reading the following section:
First, keep the space between blades and pot wall in 3mm±2mm, check it through measuring gauge and adjust the blades up and down location to standard scope.
Second, timely clean up concrete mixer machine with lift blades and pot after each use, avoid electric appliances violent vibration, keep far away from water and high temperature and pay attention to dust.
The market is changeable and we will be facing more and more serious dilemma. If we want to reduce the risk of commercial concrete mixing plant in the future, we must do the following points:
1. First of all, we should prepare enough aggregate. In the face of the current shortage of natural sand as well as the price gains which will further intensify the enterprise risk. So in the face of this situation, our concrete mixing plant should actively face to achieve the use of renewable resources. Intensify popularization for the technological application of commercial concrete mixing plant to achieve high quality, energy saving commercial concrete products.
2. Green production is the batch plant development direction of national advocacy. It is also a serious challenge for enterprise.
Concrete pump truck need maintenance, the same as other machinery.In particular, in the hot weather and cold weather operation, there are four aspects need to pay attention to.
1, construction of the hot season, it is appropriate drop cloths wet, wet straw and other covered concrete pipes, avoid sunlight.
2, construction of the cold season, it is appropriate insulation material encased concrete pipes, concrete pipes to prevent the cold, and to ensure that the temperature of the concrete into the mold.
3 ,When the level of transmission distance of more than 200M, vertical transportation distance of more than 40m, down pipes vertically arranged in horizontal or inclined pipe in front of the tube, the unit amount of construction cement batching plant mixture is less than 300kg/m3, the method must be selected piping and pumping process, to use a large diameter concrete pipes and a long conical tubes, less elbow and hose.
4, When the conveyor height exceeds the maximum transmission distance of small portable concrete pump, the pump can be used Relay (successor pump) pumping. Relay horizontal pump discharge pipe length should be consistent with the procedures in Section 5.2.4 of the Ordinance, and shall set a capacity of about 1m3, with stirring hopper device.
Which is need to pay special attention to HZS50 ready-mixed concrete mixing plant foundation construction ?
1, HZS50 level must be stirred with a spirit level and a super flat base stations detected, the loss caused by uneven Ruoyin foundation is not responsible.
2. A small HZS50 mixing station ready drawings embedded iron, embedded iron can not arbitrarily change the size, the changes must be notified, please contact the site technical guidance personnel, make a written proof;
3, requires mobile concrete batching plant for sale foundation required laying steel mesh, steel anchors are not less than the required size of the drawing; base required excavation depth and width of not less than drawing the desired size;
4, and may not arbitrarily change the size of the drawings are marked, if there are any changes need to notify the site technical guidance personnel, make a written certificate;
5, according to the technical requirements by taking small HZS50 mixing station and find a good reference point, size error between the two basis shall not be greater than 50 mm, with lime from the center of the base and the mining base size limits;
6, foundation excavation qualified after pouring concrete, need to secondary pouring must be the second pouring, label to C20 - C30;
7, when digging the modular concrete mixing plant foundation, with steel or wood fern reserve base centerline position, clear labeling requirements, based on the same two embedded iron centerline to the same line, the deviation not greater than 20mm.
Concrete mixing plant is composed of a lot of equipment, will inevitably be in the process of using some failures, which affect our construction, so prone to what exactly is the problem?
The most batch plant can not be ignored is that the temperature of this factor, the construction process to open multiple devices, each device needs to have a lot of power production can play a lot of concrete results, so there is a lot in the course of heat generation, heat and some parts of the shed can not even properly, resulting in excessively high temperature inside the machine resulting in some parts of the equipment does not work properly.
In order to avoid the generation of high temperature, we can try to the attention of the heat exchange in the production.One of the best way is in does not affect the quality of the products under the premise of lower the temperature of the feed, so heat also can get some switching equipment does not overheat.
In addition we need to pay attention to in the process of concrete mixing station construction of mobile batching plant time, stirring time is too long equipment is, the more accumulation of heat, the more likely to cause a device failure, affect our production schedule.
