Engineering Design & Consultancy
Company always takes cement engineer÷™ing design and consultancy as the leading pos ÷ition of engineering construction; conti'×≤→nually promotes the stea∏dy improvement of Chinese cemen♣∑"≠t industry engineering de ✔sign and consulting level.
Earlier back to 1980s, company developed∞≤₩ the First localization 2000★>t/d NSP cement production line, which was nλ≠∞amed as the new milestone of histor←£y of Chinese cement indΩ♣ustry, and be selected to¶♣¶♦ “the highest honor ceremony of China&rdqu>£§&o;; In mid of 1980s, fo♠®¥r the first time, co πmpany realize the Chinese locali•©≤zation of imported process and technology of NSP ∑Ω2000t/d cement production line which was aπ→lso named as the First Chinese $♣ Cement Line; By the middle of 1990s, company s'♠uccessfully developed new process and technolog÷×♥y used for 5000t/d NSP ce<®✘ment production line, which surmount kε£ey technology of large scaled equipment and enabl↓&★™e technical and economicaφ ≠l parameter to be up to Ω<"the international advancedβ≠ level and have been successfully applied→"♦ for hundreds of cement production lines; in yσ↑ear of 2006, the fact of R&÷∏D subject of process and×$ equipment for 10,000t/d NSP cement production ♠δline was authenticated and a♣σεccepted facilitates the restructuring >↔of Chinese cement industry and Chi↓±nese cement technology and &<"equipment step to internationa×&l market; In year of ∏∏ 2009, the third generation burning system♣ε by company self developed applied in Heb㥩ei Yanzhao Cement Project±σ, known as “ national NSP cemen↕>≤t clinker energy saving demonstration line&rdγ✘quo;, became the first d₩¥omestic energy saving and emission reduction wit≤>h new technology comprehensive u¥≥tilization cement industrial project.
Entered 21 century, compan★≠φ★y will continue to introduce energy-sa₽α€ving, environmental protection, and high efficieγδnt cement production line, and ₽πpromote the development of cement industry is §₹©moving into the directio←₩₩n of energy conservation and re₩γcycling economy.
Company has been commit"ted to enhance and promote ΩΩprecalcining technology, leading the di♦♦λrection of technology☆γ development of Chinese cement industry, h'€as made substantial progress and breakthroug☆$hs in the field of NSP cem™€ent production line optim≥×→ized design, technical£∞↑≠ innovation , localization i¶¶☆πnvestment, municipal wa&÷₽ste and sludge disposal.
