On the evening of October 24, the council meeting of the Concrete Machinery Branch of China Construction Machinery Industry Association was held in Xuzhou. At the meeting, all the leaders of the assoc
- Common problems and solutions of concrete mixing plant2020-03-01
The application of common quality prevention and control of concrete quality has become an indispensable link in concrete construction. The concrete of the mixing station is often prone to one or othe
- The content of machine-made sand and gravel powder is a required item of production. What are the main detection methods?2019-04-07
The content of machine-made stone powder generally has two test methods: water washing method and dry sieve method. The representative ones are American ASTMC136 or AASHTOT27, suitable for dry sieve,
- Mechanism sand often needs to be sampled and tested. How to sample mechanism sand?2019-03-29
The general method for testing and sampling of machine-made sand is:1) When sampling on the pile, the sampling locations should be evenly distributed. Before sampling, first shovel the surface of the
- What is the basis for selecting dry, wet and semi-dry artificial sand production processes?2019-03-07
First of all, it depends on the area where the artificial sand and gravel system is located, the water resources, the cleanliness of the raw materials, and the specific requirements on the aggregate a
- Why is the fineness modulus of machine-made sand unstable?2019-02-08
During the production process, the input lithology, moisture content and gradation are easy to change. The screening process will also have problems such as plugging and breakage. The efficiency and p
- In the dry production process of machine-made sand, why do we need to humidify and mix the finished sand?2019-01-13
The humidification and mixing treatment of the finished machine-made sand can make the water content of the machine-made sand to reach the dry state of the saturated surface, which is conducive to the
