The Hot-selling Construction Equipment in 2021

1. The Hot-selling Construction Equipment in 2021 Abstract: There are various types of construction equipment. What are the popular kinds in 2021? There are Asphalt hot mix plant, concrete mixer machine with pump, foundation free concrete batching plant, concrete block making machine, planetary mixer for UHPC and self loading mixer. China Hot Mix Plant When you decide to buy a China hot mix plant and start producing asphalt concrete for your project or commercial sales, you must choose the type, scale, brand and budget. Then the corresponding storage size, the number of cold storage bins, the type of pollution control, etc. must also be considered. Batch type hot mix plant The advantage of the China batch type hot mix plant lies in the high quality of the finished asphalt mixture and no waste of aggregate. Another advantage is that it can switch the

2. specifications of the mixture as needed. The mixing cycle is about 45 seconds, so a plant with a mixing tank capacity of 1500KG can produce 120 tons (tph) per hour. The aggregate is supplied by the elevator to the rotary drying drum that removes the moisture, and then it is sieved into several bins according to the particle size. After weighing, it is sent to the mixing tank and mixed with the powder and hot asphalt until the required time. Asphalt drum mix plant The asphalt drum mix plant is a continuous mixing equipment, and the first two-thirds of the drying drum unit is dedicated to dehumidification. In the last third of the unit, all the materials are thoroughly mixed. The advantage of the drum asphalt mixing plant is to reduce the hot mixing process to the most basic requirements. By eliminating most of the steps of batch production of mixing materials, the drum asphalt mixing plant can complete its work more economically. The mobile asphalt drum mix plant is much favored by many customers. Used or completely new equipment Compared with the used equipment, its condition is very good since it has been never used. And you can get out technical support during the whole process including installation and debugging. This is really a big advantage for companies that are new to the asphalt mixing plant. It is certain that the second-hand asphalt plant is much cheaper. But pay attention to whether the equipment is abused, so as to avoid frequent problems in future use. Concrete Mixer Machine with Pump The concrete mixer machine with pump can be used for mixing and pumping dry and wet materials such as cement, mortar, and fine stone concrete. It has two functions in one, so its price is relatively low, and the cost performance is high. While improving the quality of concrete mixing, it also saves time, manpower, and labor costs. It realizes the on-site mixing of concrete, mortar, etc., and pipeline transportation at the same time.Not only can it greatly improve the efficiency of the project during construction, but it is also more convenient for construction in narrow areas, sloping roofs, and high-rise buildings.

3. The concrete mixing pump has electric and diesel model. At present, it is very difficult to connect to the power supply in many areas, especially for some special projects such as slope protection or field projects. In this case, you need to choose diesel concrete mixer pump. Its mixing and pumping rely on the power of the diesel engine, which does not require electrical support, which is much more convenient. The concrete mixer with pump is matched with forklift feeding to realize 100% mechanization of feeding, mixing and pumping. The construction efficiency is 4-6 times that of concrete mixer and concrete pumps, which greatly saves labor and construction costs and simplifies the construction process. When buying a concrete mixer pump, the configuration of the product cannot be ignored. It is usually necessary to observe the thickness, workmanship and materials of other key parts of the concrete mixer machine and pump. When selecting parts, the materials of hydraulic hoses and lubricating copper pipes are as important as the "main oil pump", the heart of the delivery pump. Once a hose has a problem, it will affect the normal operation of the entire hydraulic system. In addition to the concrete mixing pump, truck mounted concrete pump and long boom concrete pump are other two main pumping equipment used in construction. They features flexible

4. movement. The maximum driving speed of the pump truck chassis can reach 80Km/h, but their cost is also very high. Blind Road Brick Making Machine The blind road brick making machine is a brick equipment specially used to produce road bricks for blind road. It is a special facility that guides the disabled to walk safely. The blind road bricks are generally yellow, with small raised dots or straight roads with protrusions. The bricks produced by Haomei blind road brick making machine can not only breathe and absorb water, but also the plants under the bricks can grow. The hardness is stronger than traditional floor tiles. In the whole paving process, the brick body is not easy to break, and the intact rate can reach more than 90%, so its price is about 20%-30% higher than that of traditional floor tiles. The blind road brick making machine also has two types. One is hydraulic concrete block making machine. It can produce permeable bricks, bread bricks, Dutch bricks, hollow block bricks, hexagonal bricks, etc., in addition to the blind bricks. It has the following advantages: 1. It is of fully automatic cycle operation, fault self-diagnosis display, and absolute safety

5. performance. 2. The concealed oil circuit reduces the space occupied by the machine, while the shortened oil pipe makes the power stronger. The main components are imported from Germany, with greater pressure, which completely solve the easy oil leakage during the long-term operation. 3. The brick machine equipment adopts Mitsubishi (Germany Siemens) industrial PLC control system, which can realize man-machine dialogue, automatic operation, random signal analysis, automatic fault diagnosis and various parameter settings, so that the machine can achieve the best working effect. 4. The unique crank connecting rod structure and the forced feeding device completely solve the problem of raw material feeding during the production of some special kinds of bricks. 5. The mould is made of special steel with fine grinding and high-frequency carburizing treatment. It adopts a plug-in design and can be replaced within a few minutes, realizing multiple functions in one machine. 6. It uses the computer to control the flow and pressure of the hydraulic system to achieve vertical synchronous vibration, frequency conversion, and braking. The advanced form of compression and vibration of the table mold makes the concrete fully liquefied and exhausted within 2-3 seconds,making products reach high density and high strength. Foundation Free Concrete Batching Plant The foundation free concrete batching plant doesn’t mean that it doesn’t completely need foundation construction, but it does not need to lay such a deep foundation like a stationary concrete batching plant. It also needs to harden the ground, make a shallow foundation, and place all equipment components on a heavy steel chassis. There are two types of foundation free concrete batching plants: hopper-lifting and belt conveying. It eliminates the process of designing and installing the foundation, greatly saving customers the time and basic cost of building a station, and can be relocated for secondary use.

6. The composition of foundation free concrete batching plant is basically the same as that of the ordinary mixing plant except for the layout and transportation mode. It is also composed of aggregate batching system, belt conveyor (lifting hopper), mixing unit, metering unit, water additive tank, control room, air control system, electrical system and other parts. The structure of he foundation-free concrete mixing plant adopts a modular design. The aggregate batching system is placed on a large chassis and is connected to the mixing unit through the middle rail frame. The water admixture box and the control room are connected together and placed in the lower part of the mixing chassis.The mixing unit is connected to the metering unit by bolts. Cables, water circuits, and air circuits are in the form of quick-plug connectors. The pros and cons of the foundation-free concrete mixing plant 1. All equipment parts are placed on a heavy steel structure chassis. The advantage is that it increases the stability and stress area of the equipment, but the disadvantage is that it increases the weight of the equipment and makes the transportation and movement of the mixing station more difficult. 2. The mixing unit and the metering unit adopt a frame structure, and the two are connected together by bolts, and the walking platform is connected by hinged connection, which can be folded along the hinge point during transportation to reduce the transportation space.

7. 3. The electrical system adopts the form of quick-plug connectors, which reduces the installation cycle of the equipment. 4. The installation base frame can be connected in different forms, which makes it more convenient to design different non-standard mixing plants according to the customer's site conditions. Planetary Mixer for UHPC and Refractory Regardless of production performance or appearance, planetary mixer is a special model that is more in line with the needs of the refractory plants. It can produce high grade concretes, especially UHPC. The planetary concrete mixer has better performance in consistency and uniformity. Convection mixing can make the concrete mix more vigorously, mixing time short, and the mixing effect even. It performs planetary operation with the support shaft of the vertical shaft mixer as the center and multiple planetary tracks work together to eliminate the dead angle of mixing, thus getting UHPC. UHPC(Ultra-High Performance Concrete) is also known as RPC(Reactive Powder Concrete). It is is the most innovative cement-based engineering material in the past thirty years. UHPC is a special

8. concrete with super high strength, super low water absorption, super durability and corrosion resistance. The UHPC currently used in the architectural design field (different from the structural field) has a compressive strength greater than 120 and a flexural strength greater than 25MPa. Although UHPC can achieve high compressive strength, the flexural strength of UHPC is mainly used for thin building components. In practical applications, the ultra-high strength of the UHPC matrix is further strengthened and toughened by a small amount of alkali-resistant glass fiber, polyvinyl alcohol fiber, and steel fiber. Fiber types frequently used in UHPC include high carbon steel, PVA, glass, carbon, etc. This material is very malleable and has the ability to deform and support bending and stretching even after initial cracking. The high compression and tensile properties of UHPC also help to improve the bond strength, thereby shortening the embedded length of steel bars in applications such as pouring between precast parts. Self Loading Concrete Mixer For Sale The self loading concrete mixer for sale is just like a small concrete mixing plant, which includes cab, hydraulic shovel, loading arm, mixing tank, discharge port, water tank, etc. The rotating speed of the mixing tank is 16 revolutions per minute, and a tank of material can be discharged in an average of about 12 minutes. The output volume per hour is about 18 m3, which can reach 200 m3 with 10 working hours, which is sufficient for a small and medium-sized project. All these are owed to its two features.

9. Self Loading There is a loading arm next to the cab of the self batching concrete truck. The driver operates in the cab, and the loading arm can perform a series of landing, shoveling, and raising actions. The bucket is raised to the mouth of the mixing tank and the raw material falls into it after the opening of the shovel is opened. Normally, two workers are enough to finish the whole process. One worker operates in the cab, and the other one assists in placing the material. It can realize self discharging 270 degrees, saving a lot of labor cost. In addition, Haomei Machinery has optimized the design of the hydraulic shovel. The arc structure of the bucket is smooth for both loading and unloading. The zigzag blade in the middle of the bucket can directly cut the cement bag when the cement is loaded. Four wheel drive The four wheel drive means that he rear wheels also have a certain steering function like the front wheels. They can not only turn in the same direction as the front wheels. but can also turn in the opposite direction to the front wheels. The self loading mixer without real four wheel drive will greatly affects its driving performance in narrow construction sites. As we all know, four wheel drive can minimize the turning radius. A small turning radius ensure the self batching concrete truck come and go smoothly.
