Chongqing gearbox co., LTD. Stick to the path of technological progress, technological innovation, has developed is applied to the center of the building materials industry drive tube mill reducer, edge transmission tube mill reducer, vertical roller mill reduction drive, roller press reducer, unilateral double transmission tube mill reducer, such as more than 10 varieties of hundreds of models, the gear for domestic initiative, not only strongly promoted the sustained and rapid development of the enterprise, also accelerated the building materials machinery and equipment localization.As early as 1985,
in the national building and the support from the tianjin cement industry design and research institute, heavy tooth begin to cement machinery complete sets of equipment of the heart — JS110 center driving mill reducer are developed.Heavy tooth make full use of the imported technology, combined with its own technical advantage and many years of experience accumulation, the hard tooth surface gear design and manufacturing technology, power double even load distribution technology, a torsional axis technique applied to research on a number of innovative technologies such as, the once successful commissioning of the gearbox, be sure to replace imported products, in 1989 won the national science and technology progress third prize.Then heavy gear company to the center of the more powerful driving mill reducer development, formed from 800 kw to 800 kw eight types of JS series products.By May 2007, heavy gear reducer JS series grinding machine has been created nearly 700 units, not only sold to more than 20 provinces and cities across the country, but also with the cement machinery complete sets of equipment exported to Malaysia, the Philippines, Pakistan, Vietnam, Zimbabwe, namibia, Brazil, Portugal, Turkey and other countries.
with the improvement of people energy saving consciousness, “saving energy and reducing consumption has become an important subject in the development of cement industry.Because than traditional tube mill energy saving about 30%, so the vertical roller mill attention and got rapid development.In 1989, heavy gear company and tianjin cement industry design and research institute jointly designed and developed vertical roller mill reducer, the first of 710 kilowatts of VBS150 type reducer, in xinxiang cement plant put into operation in 1992, and passed by China shipbuilding industry corporation and the national building ministerial appraisal of the organization.Began in 1996, the heavy gear company developed cone – planet type two-stage transmission structure VBP vertical mill reducer (now renamed JLX series according to the building materials industry standard), the first transmitted power is 2200 kw, exported to the Philippines kangda cement company, work well so far.Since
, with the nissan 3000 ~ 5000 tons of new dry process cement production line in China is increasing, and its form a complete set of 2800 ~ 4000 kw vertical mill reducer is still mainly rely on imports, this no doubt increased the construction investment of the enterprise, hindered the development of cement industry in China.Can be developed to produce China’s own power vertical roller mill reducer, and before the heavy gear technology personnel.Facing with the situation of foreign reducer break into the Chinese market, heavy tooth technology workers felt great pressure.They are determined to change this situation, to accelerate the development of building materials and equipment localization, contribute to the revitalization of national industry.Through unremitting efforts, they finally design out the JLP400 high-power reducer of vertical roller mill.
jlp400 high-power vertical roller mill reducer design is completed, heavy tooth of science and technology personnel to run all over the country, in all sorts of different occasions, different meeting promotional products, technical performance, strive to get the order.In February 2006, the China building materials industry –, conch group after many times communication with heavy gear technology personnel signed a contract, and the first order is 6 units.In September 2006, the domestic first with independent intellectual property rights JLP400 vertical roller mill reducer in heavy gear company to complete and deliver the conch group installed, running in good condition, various performance indexes reached the level of foreign same type reducer, is well received by users.Since domestic and several customers have signed contract with heavy tooth contract volume has reached more than 40 units.Heavy tooth JLP400 reducer is over foreign company reducer monopoly of China’s 5000 tons production line material vertical roller mill reducer market present situation, for the Chinese building materials machinery and equipment localization opened a new chapter.
it is relying on independent innovation, heavy gear company for building materials industry provides many varieties, high quality and high power of reducer, including: JD – JDX series edge grinding machine drive reducer of more than 2500 Taiwan, maximum transfer power 1800 kilowatts;JGX – JGXP series roller press machine of decelerate of planet of more than 100 Taiwan, maximum transmitted power 1250 kw, for the most of domestic;MDH series unilateral double transmission mill reducer more than 50 Taiwan, maximum transmitted power 7000 kw, for most of the world;JST series power split level 3 slow center driving mill reducer, the first export Brazil, maximum power of 7000 kw.JH – JY series reducer brick kiln more than 200 Taiwan, maximum transfer power 800 kw…For building materials and equipment localization, contribute to the revitalization of national industry at the same time, the heavy gear company also keeps the rapid growth of the production and business operation.
