The equipment for a cement concrete batching plant includes cement silos, concrete mixers, control room units, batching machines, screw conveyors and electronic units. In previous articles we have shared  Ready-Mixed Concrete Batching Plant Installation of Cement Silos  and  How to install mixer of a concrete batching plant . Here we share the installation steps for remaining parts of cement batching plant equipment. Installation of Control Room and Units: In spite of the variety of installation modes for the control room units of a cement plant, there is only one adopted frequently, by which the control room is independent of the plant. The parts here include the support chassis, the walking platform, legs, etc. Usually the chassis support is installed in the opposite direction, and then it’s pulled back to forward with a crane. After that the stairs of the walking platform are assembled with handrails. At last, the whole structure are fastened with bolts and fast...

The storage and control systems of a  small hot asphalt mix plant  are the same as an asphalt plant of other capacities (80 t h, 160 ton etc.). Here is a detailed introduction to their structures and functions. Asphalt Storage System The finished material storage system has a bottom type and a side type for users to choose. The bottom-mounted storage system is composed of a storage bin, a waste bin, and a transport trolley or a guide mechanism. Energy saving as it is, it has a compact structure and a small footprint. The side-mounted storage system consists of a lifting track, a lifting cart, a waste bin and a finished product bin, controlled jointly by an inverter, a photoelectric encoder and a proximity switch. The hoisting drive motor is controlled by forced air cooling and variable frequency control. The warehouse wall is equipped with a layer of 100mm rock wool for insulation, and the pneumatically controlled discharge door uses an electrically heated thermal oil d...

　　How many cement silos should an concrete mixing plant be equipped? As a matter of fact, the  concrete batching plant  cement silo  number is not stable. It’s based on the plant’s capacity and your practical needs. Even small plants might require several silos. The idea that plants of 50m3 and below demand only one cement silo is mistaken. What, then determines how many silos that a plant needs, anyway? 　　A cement silo is used to store powder materials of a concrete mixing plant. It’s called a cement silo because if a plant needs only one silo, the silo will store cement, the only indispensable powder material for ready mixed concrete. Generally speaking, the number of cement silos for a commercial concrete batching plant matches that of powder material types. If you will use three kinds of powders, you will need at least 3 silos. Extra silos might be prepared in certain cases to ensure concrete yield. For example, if the site of the mixing station is far from t...

　1. Concrete batching plant  inspection  points before starting it 　　(1) Inspect all the galvanized steel wire ropes for damage and immobility. The galvanized steel wire ropes are fixed immovably, and the damage should be replaced if the damage is more serious. 　　(2) Check whether the centrifugal pump is filled with incoming water, whether the flushing valve is closed, and whether the pipeline is cleaned and unblocked. 　　(3) Check whether the concrete weighing bucket dumping door, mixer dumping door, etc. are turned off easily and reliably. 　　(4) Check whether the lubrication points and reducer have sufficient grease. 　　(5) Check the gap between the blade of the mixer and the wear-resistant lining to keep it stable from start to finish, which is very important to increase the life of the mixer. 　　(6) Check whether the self-protection equipment of the air compressor is reliable and whether the standard air pressure is stable at 0.7MPa. 　　(7) Check whether the ele...

　 Small concrete pump truck s has become inevitable in the construction industry. Some operators remain confused about how to operate small pump trucks safely, which proves to be fatal since inappropriate operation might lead to occurrence of accidents and even injuries. How to operate a small truck, then? 　　First, the concrete pump truck must stand in solid flat ground with no barrier around or high-voltage lines above. Parking a truck at a slope is strictly forbidden. 　　 Second, once a small concrete pump truck gets at its place, the supporting legs should be stretched out immediately to keep balance of the truck. The night lamps must be opened during night to avoid accidental collision of the pump and other vehicles. 　　Third, check the temperature of hydraulic oil before having the pump getting into work, and the pump should be made to run for a longer time than usual until the oil temperature gets 15 degree above. 　　...

　　A  mobile concrete batching plant china  has been designed to save time and cost of foundation by gathering basic units of the plant into modules. It’s also known as a foundation-free concrete mixing station in China. At present, there are two types of such plants in the country: hopper lifting type and belt-type stations. The word “foundation-free” does not mean that no foundation is needed, but that relative task is reduced substantially. The ground is still need to be hardened, and there is still a shallow foundation underneath. However, there is no need for a deep foundation like with a fixed concrete plant, which reduces the investment in manpower. 　　Except the layout and transportation mode, a portable  concrete batching plant  has no difference from that of an ordinary mixing station. Its equipment composition is basically the same as that of a stationary concrete mixing plant. Its features are as below. 　　1. All equipment components are placed on a t...

he general parts of  asphalt plant batching mixing  equipment are similar regardless of their models and capacities. Here we introduce the dust remover and mixing tower of an asphalt mixing plant. Dust Remover Also known as the dust removal system, our dust remover is an area-saving unit combining the first-level gravity dust collector and the second-type bag dust collector by German technology . The filter bag made of Nomex material from DuPont of the United States has a dust emission concentration of less than 25mg / Nm3. The system has an over-temperature protection system. Mixing Tower The mixing tower gathers core units of an asphalt mixing plant: the vibrating screen, the hot silo, the weighing system and the mixing system. The vibrating screen made with German technology is a double vibrating axis linear screen. The double vibrating shaft is placed outside the screen body, and the bearings are oil-immersed in European technology for easy maintenance. The sc...

In a previous article we discussed steps of installing  concrete batching plant cement silo  parts, there we proceed to share how to install the mixer of a plant. If the client requires a closed structure, a main building for the plant must be designed and assembled, in which the installation of  concrete mixer s should also be taken into account. Here we discusses when no closed structures are needed. When the host is installed, it is generally divided into the installation of the host and the installation of the weighing system. First, install the main engine outrigger. When installing the front and rear outriggers, install them according to the welding number position of the main engine, and fix them with the pin shaft. The outriggers should be installed on the guardrail and walking platform. Although installation of concrete mixers of closed structure is not described in detail here, it is recommended to use closed structures in large stations like an  hzs...

　　The  concrete batching plant process  varies from type to type of the plant. Most plants in service are intermittent  ready-mixed concrete batching plant s the process of which roughly consists of three steps: batching and weighing of raw materials whose overall volume is no larger than the capacity of the plant’s mixer, feeding of these materials into the mixer and mixing until ready-mixed concrete is ready for delivery. 　　In detail, the process is as below. 　　1. After the plant is started, each type of raw materials shall start the uniform batching process in the order of its distance from the concrete mixer inlet and arrive at the mixing port at the same time. 　　2. Each material shall enter the anti mixer inlet evenly in proportion. 　　3. When the mixer rotates and resists mixing, the materials shall be pushed forward from the inlet to the anti mixing/pushing to the outlet to become the finished product. 　　4. After the production reaches the preset volume, ...

　The anti-pumping function is used quite a lot in tackling pipe blockage of  concrete pump s. However, it should be used with skill either with a trailer or mixer pump. In ancient China, there was a verse called "The turbulent wind precedes the mountain storm", which means that before something happens, certain signs will definitely appear, and observing these signs helps us to prevent bad things from happening. It is the same case with the plugged pipe of a concrete pump. We can sense dangers by tense observation and solve the problem of pipe plugging by anti-pumping function at the very beginning period. 　　The most effective method is to check the value of the pumping oil pressure of a trailer concrete pump. Under normal circumstances, the maximum value does not reach the set pressure. If the peak pressure of each pumping stroke rises rapidly with the alternation of the stroke and reaches the set pressure swiftly with automatic cease of the pumping cycle and noise from...

Pipe plugging happens a lot with  concrete boom pump s. The cause for pipe blockage is hindered movement of some aggregates which further reduces the movement speed of subsequent aggregates and eventually leads to gathering of aggregates in a section of the pipe. In this way, the aggregate density increases and blockage occurs. All blockage happens in such a way, but the variation of its location make differences in solutions. 　　Feeding Pipe Blockage 　　The pumping action and hydraulic system are normal. There are no abnormal sounds or vibrations, but large aggregate or agglomeration appears. 　　In such a case, you need to run the pump in reverse to destroy the agglomeration, send the commercial concrete back to the hopper, and then pump it forward. If it does not work, the blockage needs to be manually cleaned up and eliminated. 　　Distribution Valve Outlet Blockage 　　The action of the pumping system suddenly stops with an abnormal noise and strong vibrations of the ...

The installation of a   ready-mixed concrete batching plant  needs skill and steps. Here we share details about how to install it cement silos and concrete mixer. When the four brackets are finished in leather according to the pre-designed drawings, they must be fixed with anchor bolts. And concrete with a strength of C or above should be employed to reinforce the stability of the brackets. Only in this way can the fixing intensity reaches the employment level. With flake cement bins, the installer will first use the bolts to splice the silo. It will take at least one to two working days, so customers are advised to use overall cement bins if they need quick installation. Over cement silos of models below T, suitable for capacities no larger than that of an  hzs90 concrete batching plant , can be shipped directly in a container. After the cement warehouse is assembled, the dust collector and the cement warehouse roof must be connected by flanges, and then the guard...

This article gives you full knowledge about a portable plant: definition, type, features, models, capacity and price. 　　Definition 　　A portable concrete batching plant is a group of concrete production units designed to be pulled around conveniently by a trailer unit. It integrates the material storage, weighing, conveying, mixing, unloading and automatic control systems in a portable way. 　　Type 　　At present, portable concrete plants are mainly divided into two types: traction type and trailer type. The chassis of the former contains complete front and rear axles, while the latter has only the rear axle, with the front end of the chassis placed on the tractor saddle bridge. 　　Features and Application Scope 　　A portable plant is flexible in movement and site transfer. Modular units can be dissembled and installed quickly. Since little civil engineering work is needed, the plant c...

　　In operation of a concrete pump trailer, pump operators are sometimes confronted with the challenge of locating the blocked part when the pipe gets plugged. The location of the pump pipe blockage should be checked according to the type of pump and the type of concrete. 　　For Mechanical  Trailer Concrete Pump s 　　Restarts the pump for a short time. Due to the resistance caused by the blockage, the pipeline between the blockage point and the pump will cause significant vibration. The pipeline after the second point is stationary. If you cannot get a positive result with this method, stop the pump and start from one end of the pump. Check the pipe joints one by one, and loosen the first pipe joint slightly. If mortar does not come out under pressure, then this section is not blocked. Re-tighten the joint and come to the next joint. If mortar comes out, too, then the previous two sections are in a good state. Move to the third joint and repeat the steps above until you find the ...
