Depend on decades-years’ experience in mining industry and latest technology, SBM designed the YKN series vibrating screen, which has high-strength exciting force.YKN series vibrating screen adopts the eccentric vibration exciter of N series. And the transmission adopts flexible connector. As a result, the amplitude is bigger and the vibration is much more stable than old types. Also the throughput and screening efficiency are greatly improved.
VSI5X crusher (the latest vertical shaft impact crusher improved from VSI crusher) is necessary crushing equipment used in manufactured sand production line, sand & gravel production plant etc. It is widely used for manufactured sand or artificial sand production. Also, it is the mainstream truing machine for mining and construction industries.
SBM VSI Series vertical shaft impact crusher is designed by reputed German expert of SBM and every index is in world’s leading standard. It incorporates three crushing types and it can be operated 720 hours continuously. Nowadays, VSI crusher has replaced hammer crusher, roller crusher, roller ball mill, becoming the mainstream equipments in sand making business.
The vibrating screen is a kind of sieving equipment of international advanced level, developed by our company on the basis of carrying on the advantages of traditional screens and absorbing the outstanding technology from abroad. Now they are installed in about 130 countries of the global market.
T130X reinforced ultrafine mill is a new facility designed by SBM expert basing on statistical analysis and a large number of suggestions from users and the innovative design of the super pressure trapezoidal mill. It has superseded and optimized in the structural characteristics of trapezoidal MTM mill, and it also forms its own unique characteristics.
As the important part of beneficiation line, spiral classifiers are designed to provide the most effective pool area and overflow velocity requirements. According to the theory that the deposition rates are quite different because of different solid particles' specific gravity, the spiral classifier is not only able to clean the ground mineral ore, but also separate the particles briefly.
For almost 30 years, SBM has being specializing in all facets of grinding mill design and maintenance. SCM series ultrafine mill is specially designed for super fine powder grinding. Now it’s growing more and more popular with its reliable technology and perfect after-sale services.
The Raymond grinding mill was ever popular in mining, building materials, chemical engineering and metallurgy industries for size reduction, dispersion, or specialized needs, powder generation and processing for industrial process. Now MTM series grinding mill has better performance than it.
Adopting technology from the world, PY Series spring cone crusher has an excellent performance in secondary crushing and tertiary crushing process and it has become the ideal cone crusher for small capacity crushing plants of mineral ore processing industry and rocks processing industry.
Base on the plentiful experience of producing and marketing of impact crusher, SBM R&D institution designed the PFW series impact crusher. It is the newest style impact crusher and has been widely used in many industries, like chemical, metallurgy, road and bridge construction and sand making and so on.
The efficient sand washing machine of XSD series is a kind of cleaning equipment of international advanced level for sand and slag pellets, developed on the basis of introducing foreign outstanding technology of the same kind of products. According to customers’ feedback, it meets their demands well both on capacity and on the cleanliness.
