The final of the 2026 National Industry Vocational Skills Competition — the 5th National Building Materials Industry Cement & Concrete Products Fabricator Vocational Skills Competition was held in Beijing from October 30 to 31.
This event is a National Category‑2 Vocational Skills Competition, jointly hosted by the China Building Materials Federation, China Employment Training and Technical Guidance Center, and the All‑China Federation of Trade Unions for Machinery, Metallurgy and Building Materials Industry. It was organized by the China Concrete and Cement‑based Products Association. QINGDAO CO-NELE Machinery’s CMP50 vertical shaft planetary mixer was selected as the officially designated mixing equipment for this national competition.The opening ceremony took place at Jinyu Science and Technology Building, hosted by Shi Haixia, Deputy Secretary‑General of China Concrete and Cement‑based Products Association and Deputy Director of the Ready‑mixed Concrete Branch.
Dual Assessment: Theory & Practical OperationThe competition was open to the worker group, combining written theoretical examination and hands‑on skill assessment. Contestants were evaluated on theoretical knowledge, concrete mix proportion design, on‑site operation, specimen performance testing, and cost‑effectiveness analysis.A 90‑minute closed‑book written test was arranged on the afternoon of October 30. The practical skill assessment was carried out on October 31.
CO-NELE CMP50 Powers On‑site Competition TrialsThe practical session was divided into 7 groups, with 4 teams competing simultaneously in each group. CO-NELE supplied 4 sets of CMP50 vertical shaft planetary mixers to support the on‑site trials.Each team first submitted a mix design calculation sheet, which was scored by the judging panel based on five dimensions: scientific rationality, economic efficiency, feasibility, standardization and reasonableness. After evaluation, contestants prepared concrete batches on the CMP50 laboratory mixer. The mixing cycle lasted 60–90 seconds. The whole procedure started from weighing the first raw material and ended after tool cleaning and site tidying, with a total time limit of 65 minutes. Teams were allowed to remix one batch if the first trial failed, yet no extra time would be granted.During the competition, Wang Zhaojia and other leaders from the China Concrete and Cement‑based Products Association, competition judges and guests visited the test area. They observed the whole competition process and inspected the stable running performance of the CO-NELE CMP50 planetary mixer.As a precision laboratory mixing unit, the CMP50 vertical shaft planetary mixer adopts compound planetary motion of rotation and revolution, delivering homogeneous mixing with no dead zones. It is widely used for concrete mix development, new material formulation, and laboratory testing scenarios requiring high repeatability and consistent mixing quality.Being appointed as the official mixer for this national vocational skills contest represents authoritative industry recognition of CO-NELE’s equipment stability, mixing uniformity and testing consistency. CO-NELE keeps advancing precision mixing technology for concrete and cement‑based materials, supporting talent cultivation and high‑quality development of the global building materials sector.
