Concrete mixing stations are becoming more and more common, and more and more people are using concrete mixers。However, many people do not know how to clean a concrete mixer。First, before using the concrete mixer, check that the controller is in good condition。Concrete spreader图片After shutdown, pour the water and stones into the mixing bucket for 10 to 15 minutes for cleaning, and then remove the water and stones。When the operator needs to enter the mixing cylinder for cleaning, in addition to cutting off the power, remove the fuse, but also need to lock the switch box。Secondly, the concrete mixer should be regularly maintained, such as cleaning, lubrication, refueling and so on。Third, we must remember that the accumulation of concrete in the concrete mixing drum cannot be removed by hammering。We had to chisel it out。Fourth, winter use专业Concrete spreader图片Pay attention to cleaning the drum of the concrete mixer with water after the end of the work, and drain the water in the pump, water tank and water pipe to avoid frostbite of the pump, water tank and water pipe。

Concrete mixing station is mainly composed of material storage system,Concrete spreader图片Material weighing system, material conveying system, mixing system, powder storage system, powder conveying system, powder metering system, water and admixture metering system and control system and other ancillary facilities。Mixing machine Mixing machine according to its mixing mode is divided into forced mixing and self-falling mixing。Forced mixer is the mainstream used in mixing stations at home and abroad.专业Concrete spreaderIt can mix a variety of concrete such as fluid, semi-dry hard and dry hard。The self-falling mixing machine mainly mixes liquid concrete, which is rarely used in mixing stations。The forced mixer is divided into spindle planetary mixer, single horizontal shaft mixer and double horizontal shaft mixer according to the structural form。Among them, the double horizontal shaft forced mixer has good comprehensive performance。Weighing system Material weighing system is a key component that affects the quality of concrete and the cost of concrete production, which is mainly divided into three parts: aggregate weighing, powder weighing and liquid weighing。Under normal circumstances, the mixing station below 20 cubic meters per hour adopts the superposition weighing method, that is, the aggregate (sand, stone) is weighed with a scale, the cement and fly ash are weighed with a scale, the water and the liquid admixture are respectively weighed, and then the liquid admixture is put into the water weighing bucket before mixing。In the mixing station of more than 50 cubic meters per hour, the method of independent weighing of each material is used, and all weighing is controlled by electronic scales and computers。The weighing accuracy of aggregate is ±2%, the weighing accuracy of cement, powder, water and admixture is ±1%。

安康专业Concrete spreaderWhen loading, the mixture to be stirred is installed in the hopper, the feeding system is started, the wire rope pulls the hopper to climb up, when climbing to a certain height, the hopper enters the loading rack, the hopper door automatically opens, and the material is unloaded into the mixing cylinder through the funnel。JS750 mixer mixing system is composed of motor, pulley, reducer, gear, mixing device, mixing cylinder and so on。The main motor is connected to the two-stage gear reducer through the belt, and finally through the two pairs of open gears respectively drive the two horizontal mixing shaft to rotate towards the same speed。The electrical control system needs to control the main drive motor of the JS750 mixer, the motor of the water supply system, the motor of feeding, unloading, etc。All electrical control elements are located in the distribution box。The electrical components in the distribution box are installed on an iron plate, which is safe and reliable, easy to operate and maintain。The discharge system is at the bottom of the mixer, and the discharge is carried out by a manual push rod。According to customer requirements, we can produce mixers in the form of electric push rod discharge。The connection between the discharge door and the mixing cylinder shall be sealed with a sealing plate.Concrete spreader图片The position of the seal plate can be adjusted to ensure the purpose of sealing。

Machinery industry analysts pointed out that at present, the development of concrete mixing plant in China is mainly faced with three bottlenecks:Concrete spreader图片As a whole，The independent innovation ability of concrete mixing plant in China is still relatively weak，Original key technologies with independent intellectual property rights develop more slowly，The ability to independently develop and design new products is still insufficient，The application of electronics, information, automation, new materials and other high-tech transformation to enhance the research and innovation capacity of the textile industry needs to be further improved;Two.专业Concrete spreaderDue to the scale is relatively large，Low concentration，The level of technical equipment varies greatly among enterprises，The technical equipment level of a large number of small and medium-sized enterprises is still a certain gap compared with the international advanced level;Third, with the rising prices of various raw materials such as oil, natural gas and hydropower，Energy has become the third most expensive input after raw materials and capital，Energy efficiency will be a major challenge that concrete mixing plants must face，China's concrete mixing plant needs to be improved in terms of energy saving and emission reduction, eliminating backward production capacity, encouraging innovation and the application of new technologies。

The main characteristics of concrete mixing station are as follows: 1.专业Concrete spreader图片The combination structure, modular unit, installation, relocation is very convenient。2.Mixing machine and aggregate lifting adopts JS1000 type double horizontal shaft forced concrete mixer, which has good mixing quality and high efficiency。3.PLD1600 concrete batching machine is used for aggregate batching, which has accurate measurement and high production efficiency。4.Concrete spreader图片The powder is measured by electronic balance with high precision。5.The water is measured by electronic balance, and the batching precision is high。

First, communicate well with the urban construction department to ensure that the site will not be moved in a few years (to have an agreement) Second, what are the big construction projects in the city in recent years (including real estate road Bridges, etc.) Third, it is important that you have a sound sales network in the area,专业Concrete spreader图片Fourth, after determining the concrete market demand or some order intention, choose a moderate model of concrete mixer and other machinery,专业Concrete spreader图片In order to ensure production。
