The develop trend of asphalt mixing plant

图片
The hottest develop trend of asphalt mixing plant is energy saving, environmental protection and recycling. With the requirement for environmental protection, low carbon, environmental protection, high efficiency and energy saving is the recently development goals, the control of equipment noise, dust emission, harmful gas (asphalt smoke) emissions, energy saving and energy consumption is more and more strict, the requirements on the technical development of asphalt mixing plant is higher. On the other hand, development of asphalt mixing recycling plant, collect the old asphalt pavement mixture for recycling, heating, crushing, sieving, and re-mixing with regeneration agent, new asphalt, aggregate in a certain proportion into the new mixture, re-laying on the road. This method not only can save a lot of asphalt, gravel and other raw materials, but also benefit for deal with the waste to protect the environment. In the future, energy saving, environmental protection, recycling pro...

Operation principle of concrete mixers trucks for sale

图片
The concrete mixer truck is composed of the automobile chassis and the concrete mixing equipment. To the automobile chassis, the concrete mixer truck manufacturer mainly use special vehicle chassis provided by vehicle manufacturers. To the special mechanism of concrete mixers trucks for sale , it mainly comprises a power takeoff, mixing tank, front and rear supports, reducer, hydraulic system, control mechanism, cleaning system etc.. After knows the basic structure, it is turn to the operation principle. The working principle of concrete mixers trucks for sale is: while the concrete mixer truck is in the process of driving and waiting for the unloading, the power is take off through the power device from the engine, and the power drives the variable pump in hydraulic system, transfer the mechanical energy into hydraulic energy to quantitative motor, the motor drives the reducer, speed reducer drives mixing device to mixing the concrete in the tank, make it does not produce solidific...

How to start the asphalt batch mix plant correctly

图片
To make an asphalt batch mix plant working normally, we have much of work to do, preparation before starting the machine is need, while the correct way of starting the machine is also very important. It is the premise of producing qualified asphalt for pavement construction. Well, if you want to save time and improve the process efficiency, there are 7 aspects we should pay attention to when begin to operate the machine. 1, Before the power supply is connected, we should check if the position of each switch is correctly, and the order of power supply in each part should also be paid attention to. 2. When the computer is started, it should be paid attention to whether it is normal, so as to take the corresponding measures if there is something wrong. 3. According to the ratio of asphalt mixture needed of the project, set up the parameters in the computer correctly. 4, Start the air compressor, after the rated pressure is reached, operated the valves manually several times to ensu...

The unique structure of portable concrete batch plant

图片
In recent years, the demands for concrete batching plant has increasing greatly because the construction is more hot than before, so the structure and layout of batching plant has been paid more attention. As a professional concrete batching plant manufacturer, we work hard on the design better product for more suitable for the requirements of construction projects, which can take more convenience for site construction. In this trends, our YHZS portable concrete batch plant has been designed based on small and middle size concrete batching equipment. Mobile concrete mixing plant is especially suitable for the projects with short construction period, large construction area, need for frequent transitions. The YHZS mobile concrete mixing equipment is mix the charging, weighing, lifting and mixing system together, and can be moved at any time, it is the leader in mobile mixing equipment. YHZS series mobile concrete batching plant has the advantages of compact structure, small cover ar...

The Characteristics of Portable Concrete Batch Plant

We have know that concrete batching plant is the equipment for mixing concrete, in recent year, portable concrete batch plant has become the common seen type in construction site. Many friends may ask, what is the portable concrete batch plant? What are the characteristics of mobile concrete batching plant? What is the difference with stationary concrete batching plant? Wanna to know the answer? Let me tell you the answer one by one. The traditional concrete plant equipment consist of aggregate storage, weighing system, transportation, mixing, discharge and automatic control system. While mobile concrete batching plant is towed by truck for mobile work, it do not need the basic construction of stationary type, so the time from installation and put into use is shorter. This is the biggest difference between stationary concrete batching plant and mobile concrete batching plant. Portable concrete batch plant must be the essential machine in pavement, bridge, port, airport and other c...

The Operation System of Concrete Pump Truck

图片
The electric system is the core of concrete pump truck control, it decides the working condition and the efficiency of pumping work. Besides the electric system, there is also another part of control system, it is manual control operation system, it is the topic of this article. If the mechanical manipulation is adopted in operation system, rod system control mechanism and the flexible control mechanism two ways are generally used. If we put them into comparison, we could find that the flexible operating mechanism has more advantages, such as flexible layout, high transmission efficiency, less transition joint and empty trip, convenient adjustment and so on, so the operation system of the concrete pump truck is mainly of flexible control mechanism. According to the actual needs, the stepless speed regulation operation should be realized in the operation system of concrete pump truck , and the locking mechanism that can stop the control rod in any position is the key device to reali...

Preparation of asphalt batch mixing plant before starting

图片
Asphalt batch mixing plant  is the most important equipment in pavement construction. If we want to improve the efficiency of asphalt mixing plant, we must do some work before starting the equipment, which can save more time, labor and cost during processing. Preparation before working is the basic of normal operation, and it is an essential part of producing qualified asphalt. What should we do for preparation? The tips are as following. 1, Notice the weather conditions (such as changes in wind, rain, snow and temperature) to see if it has influence on production. 2, Check the level of the diesel oil tank , the heavy oil tank and the asphalt tank every morning. It should be supplemented in time when the oil level of the tank is only 1/4. 3, Check if the temperature of the asphalt has reach the required level, if the temperature is not reached, then we should be heat the asphalt until reach the standard temperature. 4, Check the amount of aggregate...
