Understanding Stationary Batching Plants A stationary batching plant is a concrete-producing plant designed to be installed in one location over an extended period. Unlike mobile batching plants, which are built for flexibility and easy relocation, stationary plants are intended for high and long-term production. These plants are typically installed at or near large construction sites, such as bridges, dams, tunnels, or high-rise buildings, where massive quantities of concrete are needed consistently and reliably. Concrete batching plants with cement silos, also known as a batch plant, is equipment that combines various ingredients to form concrete. Some of these inputs include water, air, admixtures, sand, aggregate (rocks, gravel, etc.), fly ash, silica fume, slag, and cement. A concrete batching plants with cement silos can have a variety of parts and accessories, including: mixers (either tilt drum or horizontal, or in some cases both), cement batchers, aggregate batchers, conveyors, radial stackers, aggregate bins, cement bins, heaters, chillers, cement silos, batch plant controls, and dust collectors.There are five major systems of the concrete batching plants with cement silos: mixing host, material weighing system, material conveying system, material storage system, control system and other ancillary facilities.Stationary concrete batching plants with cement silos is widely used for large and medium-sized construction work and infrastructure projects, such as commercial and residential properties, road construction, commercial concrete supply, etc. It is an ideal choice for the production of high-quality concrete with a large amount of demand.

A mobile batching plant, also known as a portable concrete batching plant, is a facility that combines various ingredients to form concrete. These ingredients typically include water, air, cement, aggregates (such as sand, gravel, or crushed stone), and admixtures (chemicals added to alter the properties of the concrete). Unlike stationary plants, mobile concrete plants are designed to be easily transported to different locations, providing flexibility and efficiency to construction projects. Like stationary batching plant, the mobile batching plant is also equipped with water, cement and additive scales which can ensure the quality of the concrete.   As a manufacturer of concrete batching plant with over 20-year experience, we have HZSY series of mobile concrete batching plant. The capacity is from 25m3/h to 90m3/h. Welcome to contact us for details and quotations. Mobility Features: One of the key features of a mobile batching plant is its mobility. It is designed to be easily transported from one location to another. The plant is mounted on a trailer or a chassis with wheels, allowing it to be towed by a vehicle. Some models may also include folding mechanisms or telescopic legs to facilitate quick setup and dismantling. Optional Features: Mobile batching plants may offer additional features to enhance their functionality and convenience. These can include built-in cement silos for cement storage, integrated control cabins for operator comfort, and auxiliary equipment such as screw conveyors or cement augers for efficient material handling. The mobile batching plant offers the advantages of on-site concrete production, eliminating the need for transportation of ready-mixed concrete. It allows for immediate and continuous availability of fresh concrete, enabling efficient construction operations, reduced dependency on external suppliers, and cost savings. It's important to note that specific features, capacities, and configurations of mobile batching plants may vary depending on the manufacturer and model. Therefore, it is recommended to refer to product catalogs or consult with manufacturers for detailed information on a specific mobile batching plant.

When it comes to modern construction and concrete production, efficiency is everything. From reducing costs to speeding up workflows, innovations in machinery play a crucial role. One such innovation that’s gaining attention is the decline belt batching plant. If you’ve heard the term but aren’t quite sure what it means, don’t worry—Sunny is here to help you understand! What Is a Batching Plant? Before diving into the specifics of a decline belt batching plant, let’s start with the basics. A batching plant (or concrete batching plant) is a facility used to combine various ingredients—such as cement, water, sand, gravel, and additives—to form concrete. Batching ensures that materials are measured and mixed in precise amounts to produce high-quality, consistent concrete. So, where does the decline belt come in? A decline belt batching plant uses a sloped (declined) conveyor belt to transport materials from storage bins (like aggregate hoppers) down to the mixing unit. This design takes advantage of gravity to move materials more efficiently. Instead of relying solely on motor power to push heavy materials upward or horizontally, the declined belt allows materials to flow downward naturally, reducing energy consumption and increasing speed. Key Benefits of a Decline Belt Batching Plant 1) High intensity and efficiency, can be applied to mix four types of ingredients. 2) JS1500 twin shaft concrete Mixer, excellent mixing performance with high efficiency and high productivity. You can also choose SICOMA mixer. 3) Adopts latest controlling technology as electronic weighting system, computer controlling and digital display. 4) Excellent environmental protection, dust collection system and anti-noise design. 5) SIEMENS PLC, TOLEDO load cell. 6) CE, ISO9001, SGS certifications.

At a time when the Chinese state is strongly supporting infrastructure and road projects, domestic high-grade highway pavement construction projects are in full swing. The smooth development of these projects is inseparable from the asphalt concrete mixing station. It is the key equipment to ensure construction quality and improve efficiency. The efficiency of the asphalt mixing plant and the quality of the finished materials are closely related to the quality of the asphalt concrete mixing plant, whether there is a failure, the type and probability of failure. Regarding the quality of asphalt mixing plants, the editor believes that reliable brands should be selected comprehensively and not just based on price. As for problems such as equipment failures, our company combines many years of project experience to analyze the causes of failures in asphalt concrete mixing plants, which are summarized as follows:   1. The oil-stone ratio is unstable The whetstone ratio refers to the ratio of the quality of asphalt to the quality of filling materials such as sand in asphalt concrete. It is the most important indicator for controlling the quality of asphalt concrete. If the oil-stone ratio is too large, "oil cake" will appear on the road surface after paving and rolling. If the oil-stone ratio is too small, the concrete material will diverge and the concrete will not be formed after rolling. These are all serious quality accidents. The main reasons are: (1) The soil/dust content in the sand and gravel aggregate seriously exceeds the standard Although the dust has been removed, the mud content in the filler is too large, and most of the asphalt is combined with the filler, commonly known as "oil absorption". There is less asphalt adhering to the surface of the gravel, making it difficult to form by rolling. (2) Metering system failure The main reason is that the zero point of the measurement system of the asphalt weighing scale and the mineral powder weighing scale drifts, causing measurement errors. Especially for asphalt measuring scales, an error of 1kg will seriously affect the oil-stone ratio. In production, the measurement system must be calibrated frequently. In actual production, due to the large amount of impurities contained in the mineral powder, the door of the mineral powder measurement bin is often not closed tightly, resulting in leakage, which seriously affects the quality of asphalt concrete.   2. Heavy dust, polluting the construction environment During construction, some mixing plants are filled with dust, seriously polluting the environment and affecting the health of workers. The main reasons are: (1) The mud/dust content in the sand and gravel aggregate is too large and seriously exceeds the standard. (2) Dust removal system failure Asphalt mixing plants currently generally use bag dust collectors, which are made of special materials with small pores, good air permeability, and high temperature resistance. They have good dust removal effects and can meet environmental protection requirements. However, they have one disadvantage: they are expensive. In order to save money, some units do not replace the dust bag in time after it is damaged. The bag is seriously damaged, the fuel is not burned completely, and impurities are adsorbed on the surface of the bag, causing blockage and causing dust at the production site.   3. Maintenance of asphalt concrete mixing station The maintenance of asphalt concrete mixing plants is generally divided into tank maintenance, winch system maintenance and adjustment, stroke limiter adjustment and maintenance, wire rope and pulley maintenance, lifting hopper maintenance, track and track bracket maintenance, etc. wait. At the construction site, the concrete mixing station is a piece of equipment that is prone to failure. We must strengthen the maintenance of the equipment. This will help ensure safe construction at the construction site, improve the equipment integrity rate, reduce equipment failures, ensure the quality of concrete, and improve the equipment. production capacity and achieve double harvest of social and economic benefits.

1. Cement scale weighing inaccurately   This fault shows that the correct value can be displayed after adding weights for calibration, but the numbers do not return to zero after unloading. After clearing and reloading the weights, the numbers change greatly, but check that the sensor resistance value is within the normal range, and there is no problem with the instrument. Analyzed reasons may include: the angle iron fixing the scale frame for transportation has not been removed; the pressure head and pressure plate are stuck; the scale body interferes with the outside world; the three sensor models do not match; and the load is off-center when weighing materials. The method to deal with the failure of the concrete mixing station is: if the angle iron fixing the scale frame for transportation has not been removed, it should be removed in time; if the pressure head or pressure plate is stuck, it should be dealt with in time to make it smooth and without resistance; if the scale body interferes with the outside world , should be isolated in time; if the three sensor models do not match, sensors of the same model should be replaced; if the material is unbalanced, adjustments should be made.   2.The discharge door of the collecting tank is difficult to open and close when there is no material.   This fault is manifested by slow and weak movement of the cylinder, but check that there is no friction or sticking in the mechanical part of the discharge door, and that there is no air leakage in the solenoid valve or cylinder. The reasons may include: poor air path. For example, the air-water separator filter element of the triple part at the air source is too dirty, causing the air path to be unsmooth, which reduces the gas flow per unit time, thus causing the cylinder to move slowly; the muffler is too dirty. When the cylinder moves, the pressure difference between the rod chamber and the rodless chamber becomes smaller, causing the cylinder to move slowly. The method to deal with the failure of the concrete mixing station is: if the air path is not smooth, the filter element should be cleaned or replaced in time; if the muffler is too dirty, the muffler should be cleaned in time.   3.No material is discharged from the discharge port   This fault is manifested as when the contactor is closed and the motor rotates clockwise, the material is not discharged from the outlet of the screw conveyor, and the air switch will trip after a short time; after closing the air switch, the motor still trips, and observe the powder No coagulation phenomenon. Analysis of the possible reasons includes: the mother machine is reversed; the air switch is damaged; the mother machine motor wiring may have poor contact in one phase. The method to deal with the failure of the concrete mixing station is: if the mother machine is reversed, just adjust any two of the mother machine motor wiring; if the air switch is damaged, it should be replaced; if one phase of the mother machine motor wiring is in poor contact, it should be checked and dealt with.

  In recent years, with the continuous advancement of national policies and the huge demand for infrastructure projects such as high-speed rail and expressway, the number of mixing stations has grown rapidly and has become an indispensable equipment in construction. However, with the continuous development of the mixing station market, the limitations of ordinary mixing stations such as low capacity utilization and single operating products have become increasingly prominent. In order to break through this limitation, Sunny innovatively launched a concrete/mortar dual-purpose mixing station. The station has been carefully designed to have dual functions, dual qualifications, dual-purpose mixing hosts, and dual-purpose configurations. It can realize "one station with dual uses" and create new value for customers.   Dual function ★It has the production function of concrete and mortar, and also has the function of producing high-quality machine-blasted mortar that the concrete mixing station does not have. ★The unique dual-purpose function increases customer profit points, while avoiding the risk of low capacity utilization of a single mortar station or a single commercial mixing station, improving operating flexibility and reducing operating risks.   Sunny SZ series dual-use stations meet the application requirements for both concrete and mortar production qualifications. In order to ensure the quality of wet-mixed mortar, the construction committees of some provinces require developers and construction companies in policy terms to only use mortars mixed with dual-purpose mixing stations starting with SZ or special mortar stations to meet the standards for use of ready-mixed mortar. Traditional mortar is no longer recognized. Mortar produced by concrete mixing plant. Dual purpose mixing host In view of the characteristics of "fine aggregate, small load, and long time" in mortar production and "coarse aggregate and large load" in concrete production, through the discrete analysis Edem software based on the particle system, and using the Sunny Cloud Supercomputing Center for simulation optimization, we obtained According to the optimal blade deflection angle, linear speed and phase difference angle, a mortar/concrete dual-purpose mixing host was developed. Dual use configuration ★Automatically cleans the waiting hopper, effectively preventing stones from remaining in the waiting hopper and causing them to enter the mortar production; ★The three-sand and two-stone batching station with a large inclination angle prevents the accumulation of materials when discharging wet-mixed mortar, and adopts internal vibration-type arch breaking to ensure smooth discharging; ★Standardly equipped with 1 set of high-precision micro-admixture weighing system and 3 water-based admixture weighing systems; ★Dual-purpose mixing host and dual-purpose control system. One investment, double returns. Dual-purpose in one place, the king of mixing! Sunny mortar/concrete dual-purpose mixing station is of excellent quality and economical, creating maximum value for customers!
