What are the two batching methods of the concrete batching machine? According to our technical staff, the concrete batching machine is divided into belt type and cylinder type according to the batching control method.
1. Belt batching type: Its structure is mostly a raw material storage hopper at the upper part, a measuring hopper at the bottom, and a discharge conveyor belt at the bottom. The storage hopper is used to store the raw materials to be dispensed. The bottom of the storage hopper is directly opposite the ingredient conveyor belt. The principle: the batching starts, the belt conveyor starts to take out the raw materials in the storage hopper to the set value, and the belt stops. Then under the control of the control instrument, the next several materials are configured in turn. After all the materials are configured, the meter control starts the unloading belt. The material is sent to the next step (such as the mixer bucket or the conveyor belt). The belt batching type is mostly used in small and medium-sized construction sites. Because its material base is small, in order to further improve the batching accuracy and reduce the error value without affecting the distribution efficiency , Can use low-speed batching, fast unloading method. In order to reduce the purchase cost, users of such batching machines often wish to borrow the batching machine's measuring bucket to measure bulk cement at the same time, and use the cement screw conveyor to drive the cement in the cement silo into the batching machine's measuring bucket. Generally, this usage is not advocated. Because the cement has good fluidity, a small amount of cement overflows between the gap between the metering bucket and the conveyor belt, which causes dust pollution on the site or loss of cement. If you want to use this method, you must use a grooved belt idler, and add a bucket edge. Soft and thin ribs can control cement spillage.
2. Cylinder batching and batching machine: Most of its structure is a raw material storage hopper. To increase the storage capacity, a height plate is provided, and the bottom is a measuring hopper: an overall measuring hopper can be equipped under each batching door, so that each material is dispensed in sequence. The same measuring bucket (cumulative measurement) can also be equipped with a single measuring bucket (each weighing each material) under each batching door, and the materials that have been measured are sent to the next link by the bottom belt conveyor. The cylinder batching method uses the gravity gravity flow down the stairs. Therefore, the batching speed is fast and it is suitable for medium and large mixing stations. Currently, more than HZS50 concrete mixing stations (buildings) are used.
Questions and answers about concrete machinery and equipment
Q: How big will it be to build 35 concrete stations? How much does it take?
Answer: The floor area of HZS50 mixing station equipment is not large, about: 20m * 14m. In addition to sand and gravel, office areas, parking areas, etc., at least three acres of land are required.
Q: How about the production capacity of HZS180 concrete mixing station
Answer: HZS180 concrete mixing plant belongs to large concrete mixing plant. The actual production capacity per hour is about 150 cubic meters on average.
Q: What is the cause of the abnormal sound of the twin-shaft mandatory concrete mixer hoist reducer? How to eliminate it?
Answer: The tapered roller bearing is damaged, just replace the bearing.
Q: What are the concrete mixing station systems? Which aspects are generally needed?
Answer: The equipment operator management system, the driver management system, the dispatcher's post responsibilities, the scale management system, the financial system, the logistics staff management physique, and business management.
Q: What are the standard configuration of 25 concrete stations? It's better to be more detailed
A: The standard configuration is: one JS500 mainframe, one PLD800 three-story batching machine, one water metering, one cement metering, one additive metering, one fly ash metering, two 60T powder tanks, LSY219 * 8M Two sets of delivery pumps, one set of gas system and one set of control system.
Q: What is the power of the concrete mixing station at 25 stations? Configure the transformer
Answer: According to the calculation of the host JS500 mixer, the mixing motor is 18.5KW, the lifting motor is 5.5KW, the pump motor is 1.5KW, totaling 25.5KW.
Q: How much is the JS1500 concrete mixer? Why is there such a big difference in price?
Answer: JS1500 is a compulsory double-horizontal concrete mixer. According to the different mixing methods (single-motor pneumatic or dual-motor startup) and the difference in the feeding method (lift bucket or conveyor belt), the price is about 150,000 yuan.
Q: Is the concrete mixing machine easy to install? Is your manufacturer responsible?
A: If it is a stand-alone device, it is generally relatively simple. If it is a complete set of equipment, the manufacturer will usually arrange technical staff to guide the installation and commissioning on site, and conduct technical training such as equipment operation and maintenance.
Q: What are the supporting facilities for commercial mixed stations? Out of stirring
A: In brief, the supporting equipment for commercial concrete mixing stations is as follows: concrete mixing equipment, concrete transportation equipment, experimental equipment, forklifts, weighing equipment, ground pumps, automobile pumps, etc.
