What issues should be noted when purchasing a concrete mixing plant

With the rapid development of urban construction in our country, the demand for concrete mixing plants is also increasing, and we are choosing more and more manufacturers. The quality of equipment is related to production efficiency and concrete quality, so we need to be cautious when purchasing concrete mixing plant equipment. The following are the issues that Zhengzhou Manxing Machinery summarizes for everyone to pay attention to when purchasing a mixing plant:

1. Whether the equipment of the concrete mixing plant is matched. Some users may have their own set of configurations when purchasing the mixing plant, so they tend to choose equipment based on their own choices and ignore the manufacturer's suggestions. Generally, the manufacturer provides standard equipment, which means complete production supporting equipment. So when choosing, try to consider the manufacturer's opinions as much as possible.

2. The price and performance of concrete mixing plants. The quality and price of a concrete mixing plant are directly proportional, so when selecting equipment, it is important not to lower the price standard too low. If you think you have an advantage in price, it is actually the opposite. The performance of concrete mixing plants is not only related to quality, but also closely related to the user's own operation. Therefore, professional training is also indispensable in the early stage of production.

Q&A on Concrete Mixing Machinery:

Q: How much does it cost to build an HZS75 concrete mixing plant?

Answer: A set of HZS75 mixing equipment for a mixing plant requires an investment of about 400000 yuan. If concrete transport trucks, shovels, weighing scales, experimental equipment, etc. are added, the required cost will be higher.

Q: Is there anything special about the HZS60 concrete mixing plant mainframe?

Answer: The JS1000, a popular HZS60 station host model, has a compact structure, strong mixing force, uniform mixing, and smooth operation.

Q: What is the main power of the concrete mixing plant 25? Configure transformer

Answer: According to the JS500 mixer, the mixing motor is 18.5KW, the lifting motor is 5.5KW, and the water pump motor is 1.5KW, totaling 25.5KW.

Q: What is the typical discharge height for concrete at station 75?

Answer: The discharge height of the mixing plant is generally 3.8 meters, but with the change of concrete transport vehicles, it is now adjusted to 4.1 meters for discharge.

Q: What is the composition of the feeding system for a forced double axis concrete mixer?

Answer: The feeding system consists of a hoisting mechanism, feeding rack, hopper, feeding nozzle, etc.

The brake motor drives the drum to rotate through the reducer, and the steel wire rope pulls the hopper up along the feeding rack track through the pulley to climb to a certain height. When a pair of rollers on the bottom hopper door enter the horizontal fork of the feeding rack, the hopper door automatically opens, and the material is fed into the mixing bucket through the feeding nozzle. To ensure accurate positioning of the hopper, a limit switch is installed on the feeding rack. The upper limit has two limit switches, which respectively limit and protect the upward limit of the hopper. There is only one limit switch for the lower limit position. When the hopper descends to the bottom of the pit, the steel wire rope becomes slightly loose, and the spring lever mechanism activates the lower limit position, causing the winch mechanism to automatically stop. The lower limit and spring lever mechanism are both installed on the top of the upper guide rail. The upper part of the feeding rack can be folded. Connect with bolts and fold it during transportation to lower the transport height. The brake motor ensures that the hopper can reliably stop at any position during full load operation, and the magnitude of the braking torque is adjusted by the large nut on the back seat of the motor.

Q: What is the weighing accuracy of the HZS90 concrete mixing plant batching machine, and is there a specific standard?

Answer: According to relevant industry standards, the allowable error range for the weighing accuracy of sand and gravel aggregates is ± 2%, and the weighing accuracy of other raw materials is ± 1%

Q: How much does a control system for a small concrete mixing plant cost? How many types of control systems are there?

Answer: Control systems are divided into simple centralized control systems and fully automatic computer control systems, which have significant differences. It cannot be generalized, the cost ranges from one or two thousand yuan to five or six thousand yuan.

Q: Is there any mobile concrete station at 25? Convenient to use in different places

Answer: The HZS25 concrete mixing plant is mobile, with the main engine, batching machine, metering system, control system, and lifting bucket all on one trailer, making migration very convenient.

Q: How to install HZS120 concrete mixing plant?

Answer: The author does not recommend users to install this type of 120 mixing plant on their own. Generally speaking, the equipment manufacturer should arrange technical personnel to guide installation and commissioning work at the user's site.
