Quality appraisal of dry mixed mortar production line

dry mortar production line is an automated production line, mainly used to produce dry mixed mortar. It consists of multiple processes, including sand and gravel batching, stirring, mixing, packaging, etc.
dry mortar production line has the advantages of high degree of automation, high production efficiency and stable product quality, so it is widely used in the construction industry. In addition, the dry mortar production line also has the advantages of low energy consumption, no pollution, safety and reliability, etc., so it is favored by more and more construction industries.
Zhongke Testing and Appraisal Institute can provide quality appraisal services for dry-mixed mortar production lines and make accurate appraisals in terms of product design analysis, load analysis and product quality analysis.

According to the structure of the equipment, dry-mix mortar production lines can be mainly divided into: simple dry-mix mortar production lines, basic dry-mix mortar production lines, semi-automatic dry-mix mortar production lines and fully-automatic dry-mix mortar production lines.

A building materials company signed a "Product Purchase and Sales Contract" with a technology company and purchased a dry-mixed mortar production line from it. After acceptance, it was found that the production line capacity was lower than the number agreed in the contract, so it was returned to a technology company for rectification. However, the technology company still failed to meet the technical requirements after repairs. The engineering equipment company therefore appealed to court.
Our company was entrusted by the court to undertake the quality analysis of the "dry-mixed mortar production line" involved in this case.
identification and analysis results: The
quality analysis expert group discussed and comprehensively technical analyzed the relevant information, on-site investigation and inspection conditions, and inspection and testing data of the "dry-mixed mortar production line" involved in the case, and made the following quality analysis opinions:
1, the "dry-mixed mortar production line" involved in the case The "production line" configuration lacks a ton packaging system, and the number and brand of packaging machines configured in the packaging system are inconsistent with the contract;
2. It is produced according to the existing process, and the production line capacity is about 40 tons/h;
3. During the on-site startup test, the continuous mixer system in the dry-mixed mortar production line involved in the case failed to start and did not operate normally.
