Trailer mounted concrete pump is an advanced concrete pouring device that mixes concrete on the spot and sends it directly to target pouring points. In other words, it combines functions of concrete mixing and pumping. Owing to uneven qualities of suppliers, the trailer mounted concrete pump price is changeable from supplier to supplier. As a responsible supplier, Haomei believes that any product has its own reasonable price, and you can get a rough idea of the concrete pump price from a certain supplier based on the following two points. trailer mounted concrete pump price The first element influencing trailer mounted concrete pump price of a supplier is its production cost. Not a few suppliers boast that their pumps are much cheaper than those from other factories, but the fact is that they supply pumps of inferior components which would certainly have a negative influence in operation. As known to all, it’s really disturbing to use such a weak pump in mixing materials as hard as aggregates and concrete! Responsible manufacturers like Haomei would rather reduce profit to offer pumps of reliable properties and long service life, because public praise is the best advertisement. They are also willing to invest heavily in new technology and production device. The second is after-sales service. The trailer mounted concrete pump price is also closely related to its after-sales service which provides guarantee for any problem during your using of the pump. How can anyone trust a supplier with poor service any way? Even the best pump might get failures, which would delay your project and damage your reputation in the industry if not tackled instantly. Excellent after-sales service, however, takes money for manual work and material cost. That’s one of the reasons why high quality pumps are more expensive.

Relationship between cement weighing and other mixing equipment in concrete mixing plant The calculation amount of cement in the concrete mixing plant is as follows: Cement weighing parameters in concrete mixing plant (1) the relationship between cement content and conveying resistance and concrete conveying pump volume efficiency should be appropriate. If the amount of cement is insufficient, the efficiency of pumping volume decreases and the transport resistance increases obviously. Moreover, this kind of concrete is poor in water retention and is prone to bleeding, segregation and blockage. If the cement content is too large, it will make the concrete too viscous and increase the transportation resistance, but the pump volume efficiency changes little. (2) relation between cement weighing and aggregate variety The amount of cement of gravel concrete is higher than that of gravel aggregate with the same size and grade. For fine aggregate, the use of artificial crushing sand is much more cement than natural sand. (3) the relationship between cement content and pipe diameter and pipe length The smaller the pipe diameter and the longer the pipe, the higher the mobility, lubricity and water retention of concrete are required. Therefore, the amount of cement should be increased. The above is the amount of cement in the concrete mixing station. In a more practical engineering situation, the amount of other raw materials can be proportioned, and the amount of cement can be reasonably controlled according to the different ingredients, so that appropriate concrete can be produced. That is the haomei machinery built machine for cement concrete mixing plant weighing relations with other mixing devices, to learn more about this aspect of knowledge, to ask about prices forced concrete mixer, price list or understand concrete mixing station and know the price of forced concrete mixer,  js750 js1000 js1500 concrete mixer, please click on online consulting, the haomei machinery built machine details for you.

The main components of the control system of concrete mixing station include computer, programmable controller, proportioning instrument, power device (ac contactor, air switch), etc. According to different control methods, the control system is divided into three categories. Distributed microcomputer control system This kind of control system of concrete mixing station is widely used in the early design of mixing station. The core of the control system is programmable controller. The high quality computer is only used for printing management reports. In particular, the large commercial concrete mixing station has increasingly complex functional requirements for the control system, which is not very applicable. Centralized microcomputer control system The control system of the concrete mixer station of this category integrates the computer control and management functions on a single computer, which has heavy computer tasks. Besides, the statistics of report data in the production process cannot be carried out synchronously, and the statistics data cannot be collected at any time. The measurement is subject to too much interference from human factors, commonly known as “semi-automatic control system”. Centralized dual microcomputer control system This type of mixing station control system solves the interference of human factors in measurement. A special batching control instrument is adopted, and the production control and management functions are divided into two computers, non-interference, production control and reporting statistics are carried out synchronously, and the management computer can also be used as a production backup machine, providing a network interface with superior computers. That is what we usually call the automatic control system of the mixing station. The above are three kinds of control systems of concrete mixing station. At present, semi-automatic control system and automatic control system are more common, and the latter is more expensive than the former. The manufacturer can choose the appropriate control system for the concrete mixing station according to its own engineering requirements and equipment budget.

The topic we are talking about today is about the weighing problem of concrete mixing plant . The cost of the mixing plant is bound to be higher when the amount is too large, and the quality of concrete cannot be guaranteed when the amount is low. Therefore, don’t relax the inspection and maintenance of the weighing system at any time. So, in everyday situations, what should we do when we encounter the weighing problem of the mixing plant ? Know the weighing sensor of concrete mixing plant The weight sensor is a device which changes the object mass signal into measurable electrical signal output. From the above definition, we can know that the weighing sensor is an electrical element, through which we can measure the weight of the raw material we need. The most commonly used load cells in general concrete mixers are shear beam and s-shaped pull type weighing sensors, as shown in the two figures below. S-shaped pull-type weighing sensor Shear beam type weighing sensor In the concrete mixing plant , the measurement of aggregate, powder and water is made of shear beam type weighing sensor, while the s-shaped pull-type weighing sensor is mainly used in the measurement of admixture. Both the working principle of about the same, sensors built into the elastic element, if there are external forces, on which the elastic element deformation will occur, and adhesion on the resistors, so will produce deformation resistance resistance will change, through the change of the resistance, the output of the sensor will change the current or voltage, this process will object is converted into electrical signals, the weight of the electrical signal through interpretation, finally through the display screen, this is what we are weighing the weight of the object value. concrete mixing plants 2. Common fault causes and treatment methods of sensors in concrete mixing plant 1. No weighing reading This fault is generally more common, a certain weighing value is zero, regardless of whether there is anything above it, its weighing value is always zero. The above faults are caused by the following reasons: a, damage of sensor, b, circuit break, c, fault of signal transmitter, d, poor contact of junction box A. Sensor damage: the voltage value of the sensor output signal line when detecting the null and the raw materials above. If the values of both are the same, the sensor is damaged. The sensor output signals are detected according to the following figure. The working principle and boundary mode of different brands of sensors are basically the same. The following figure shows the connection principle of 6-wire sensor. B. short circuit in the circuit: if the sensor is not damaged, it can be checked to see if there is any break in the circuit. The method is to follow the circuit of the sensor to see if there is any mark of skin or shear. C. Fault of signal transmitter: after the above two reasons are eliminated, we finally check the signal transmitter. Its detection method is basically similar to that of the sensor. D. Poor contact of the junction box: this is mainly because the connection is not made firmly. 2. The weight value fluctuates This phenomenon is manifested in the fluctuation of a certain weight value, which is beyond the normal error range. Main reasons: a. large mechanical vibration near the sensor; b. high frequency signal transmitter near the mixing station (including mobile signal tower, substation with ultra-high voltage) If the hopper attached to the sensor mounting seat is purely mechanical vibration, the deformation of the sensor will be constantly changing. Therefore, the weight value of the weight will cause the fluctuation. As for the problem of signal interference near the concrete mixing station, it should choose a reasonable site at the beginning of the construction of the station and stay away from these interference sources. The weighing system 3. Weighing system maintenance Weighing sensor is a precision electrical element, which needs to be kept away from dust, water and other substances. It is necessary to keep the sensor clean around, so some protective cover can be added to the sensor. At the same time, the weighing system needs to be recalibrated at intervals. When checking the failure of the weighing system in the concrete mixing plant , we’d better adopt the elimination method to minimize the root cause of the problem.

While there are so advanced concrete mixer for sale in the market, the key point of mixing more concrete come to the daily operation. Concrete mixer When we have bought concrete mixer for sale, the next step is check whether there are problems on the equipment, the check list is: check whether the motor, cylinder, bearing seat, etc. has damage, whether the fasteners is loose, if any one is loose, we should tighten it, the support foundation should be formation concrete floor, the concrete mixer should tied to the rack by rope while transfer, it can not be set in the mixing shaft. Then is the operating procedures of concrete mixer 1, before starting the concrete mixer, check whether the rotating part and the barrel has scratched touch phenomenon firstly, if there is scratch phenomenon, the part should be promptly adjusted. 2, clean up debris inside the barrel, the cylinder should be limited before starting. 3, the stirring shaft rotation direction should be the same as the sign marked at the end of cylinder. 4, loaded concrete materials must be cleared of metal or other debris. 5, according to the mixing time to adjust the timing of the mixer, pay attention to the time must be adjusted in the case of power off.

The below introduce the concrete mixing plant three different methods of feeding. The production sequence of concrete mixing plant is the process of feeding, mixing, and discharging. 1. Once feeding method: that is, mixed all kinds of sand raw material, cement, and water together and then feeding them into the mixing cylinder at one time. This method is widely used in the large belt type concrete batching plant and project type concrete mixing plant, the advantages of this method are high cutting speed, high efficiency, and it avoids the problems in the process of various feeding material. But it is worth noting that, in the actual feeding material, in order to reduce the flying phenomenon of cement, it is best to pour sand stone, and then is the cement, and then pours a little sand stone, and then mixing with water. 2.Twice feeding method: commonly known as the mixed cement mortar or mixed cement paste method. The so-called mixed in advance means stirring well in advance, that is adding the cement and sand and stone, water to the mixing tube, and then mixed them into cement mortar evenly, and then added alone stirred into uniform gravel concrete. The property of domestic common concrete mixer equipped on concrete mixing plant is forced mixer the mixer. If the mixer feeds material by this method, the pre-mixed time is very short, and it very saves the whole mixing time. 3.The sand enveloped with cement : that is also called SEC method. Generally, the concrete product produced by this feeding material method is also called SEC concrete or the shell making concrete. The detail feeding method of this method is to add a small amount of specific water into the surface of sand and stone, when the water content of the sand stone reaches about 20%, added gravel and mixed with the prepared wet sand, and then added cement to mix together. The intensity of concrete products using this feeding method of batch plant machine is relatively high, and it’s generally applicable to special construction project
