Mixer quality appraisal

mixer is a common mixing equipment, mainly used to uniformly mix two or more materials with different components. Its principle is to disturb and mix materials with different components through rotating mixing blades to achieve a certain degree of uniformity.
mixer is mainly used for mixing different materials in chemical, pharmaceutical, food and other industries, and can greatly improve production efficiency. The mixer adopts an efficient mixing design to ensure the high quality and consistency of the mix, and the mixed materials are uniform and irregular.
Zhongke Testing and Appraisal Institute can provide mixer quality appraisal services and make accurate appraisals in terms of product design analysis, load analysis and product quality analysis.

mixers can be mainly divided into several types such as double cone mixers, single-shaft mixers, double-shaft mixers, three-dimensional mixers, and drum mixers.

JB/T 12049-2014 Cylinder granulating mixer

A ceramic factory signed a "Fully Automatic Intelligent Mixer Sales Contract" with an engineering company, agreeing that the technology company would contract for a set of fully automatic intelligent mixers. After the project was completed, the ceramic factory debugged the equipment. As a result, the output value previously promised by the engineering company was far from the actual output value after debugging, and the defective rate was extremely high. The engineering company believed that it was due to operational problems, and the ceramic factory believed that it was due to the engineering company's product quality problems, and a dispute arose between the two parties. .
Our company was entrusted by the court to undertake the quality analysis of the "mixer" involved in this case.
identification and analysis results: The
quality analysis expert group discussed and comprehensively analyzed the relevant information, on-site investigation and inspection data, and inspection and testing data of the "mixer" involved in the case, and made the following quality analysis opinions:
1. During no-load operation, the maximum operating speed and stroke of the dispensing head X/Y/Z (except the Y-axis direction stroke) do not meet the requirements of the "Fully Automatic Intelligent Mixer Sales Contract"; the X-axis direction running accuracy does not meet the requirements of the "Fully Automatic Intelligent Mixer Sales Contract".
2. The host, pressure regulating valve, zoom lens, digital display, power supply and other components are inconsistent with the elements agreed in the "Fully Automatic Intelligent Mixer Sales Contract"; solenoid valves, pneumatic joints, couplings, oil-water separation and other components do not have brand marks.
3. When the "Fully Automatic Intelligent Mixer Sales Contract" was signed, the mandatory national standards (GB5226.1-2008) applicable to the equipment involved were tested and appraised, and no unqualified items were found.
