Cement quality is directly related to the quality of the construction is extremely durable, is the key link of the quality control of the mixing station! The cement industry is now a mess: clinker unqualified is commonplace, cement clinker content far below the standard value is the norm, "small cement" fundamental cannot be called cement, only call for abrasive powder. Cement supervision serious deficiencies! The intensity of light, setting time and stability are not enough. Henan Daswell Machinery Co., Ltd,is a professional manufacturer and trader specializing in the research, development and production of construction machinery for nearly 30 years. Our main products are as follows:MP500 Planetary Concrete Mixer,concrete batching plants,concrete mixer,blocking making machine,concrete pump,etc. 1, clinker: the standard provisions, calcium silicate mineral is not less than 66% concrete mixer machine, the oxidation of calcium and silica oxide quality than not less than 2. Can our cement plants often pass these indicators?! Often only strength test. 2 portable cement mixers for sale, cement clinker content: standard, small cement mixer ordinary portland cement clinker + gypsum content should be greater than or equal to 80%, and less than 95%. Can now, even the content of cement plant clinker are generally only 65%-70%, more do not mention all around the capital of small cement plant (in fact, can only call grinding station JS series concrete mixer, also do not know how to get the name of the cement plant), the general cement clinker content is only about 50%. Small cement can not be called cement, at best, it can be called the mixture! 3, detection means: the cement by the Technical Supervision Bureau supervision and management, sampling once a year, simply can not constrain the production of cement factory! National inspection standards of the test project will be the strength of the mixer mixer mixer mixer mixer mixer mixer mixer, setting time and stability, and some chemical indicators, has been far from enough! The small cement with the hands and feet are easy to meet these targets! |
