Development Prospects Of The Domestic Raymond Mill

China mining machinery industry has introduced a large number of host developed countries design and manufacturing technology, gradually adopted the international advanced sealing system design concept and application of the sealing device technology.However, due to the constraints of the domestic raymond industrial manufacturing level, the level of application of the mine mechanical seal technology still lags behind the international advanced level of about 20-25 years.Host no leak about 1/10 of the lack of international advanced level of the normal working hours only 400h.Application status: product variety and quality of domestic raymond is still unable to meet the needs of development and supporting the introduction of advanced manufacturing technology, mining machinery.In fact, nearly one thousand services for the mining machinery industry in china rubber raymond manufacturers, but with better production conditions and technological capabilities are only 40 i.Which has strong technical capabilities, enterprises only 7-8 sets of advanced equipment (in military seal products produced by the professional institute is not listed).Nevertheless, the production of sealing products in terms of quality and service life is still with foreign advanced level more or less the gap.Product variety and quality of domestic raymond is unable to meet the introduction of advanced manufacturing technology, product development and supporting a case in point.Second, the demand rather dump truck lifting device with u-shaped ring of small cross section (au).20 years, the joint efforts of domestic scientific and technical personnel, the establishment of a complete integration of the various types of raymond and iso/tc131/sc7 to install cavity national standards system.Established standards and various types of the raymond international standards raymond size series, raymond performance indicators and quality of raymond appearance, raymond packaging, storage, transportation, etc.In order to facilitate the mining machinery, the high pressure hydraulic machinery products sealing system design and selection of raymond.But in practice there are still many drawbacks existing.The main reason is too weak industrial base, the quality and variety of raw materials is not satisfactory, management is not standardized.Gap especially in the hydraulic pump, hydraulic motor and gearbox rotary oil seals and hydraulic cylinder reciprocating seal the product quality is the worst.With its high quality products such as mineral sand washer、sand washing machine、impact stone crusher、henan hongxing mining machinery co.Ltd has ascended in the front rank of the world in the exporting of mining equipments.Rock cone crusher : http://www.Hxjq-crushers.Com/27.Htmcement rotating dryer : http://www.Hxjq-crushers.Com/11.Htmore vibrating feeder : http://www.Hxjqcrusher.Com/crusher/china-vibrating-feeder.Html.
