MB5X158 Pendulous Suspension Grinding Mill is the new equipment that kefid launched in its 30th year. As one of the most recognized equipment, it covers all the technical innovation, like the main mill, classifier, auxiliary equipment, etc. And it is morewear-resisting, convenient to operate, energy-efficient and environment-friendly, which will bring you the new experience of non-metallic mineral powder processing.
Based on more than 30 years of experiences, VSI6X Series Vertical Shaft Impact Crusher carrying many patents amazes the market greatly. This machine is possess of four openings impeller, special sealing structure and sealed cartridge bearing structure, which makes production convenient and efficient.
Applications: metallic and non-metallic ore, building material, artificial sand making and every kind of metallurgical slag
Impeller structure adopts the design of four openings to improve the material throughput. Compared to the three opening impeller, the crushing efficiency is improved by 20%.
“Crushing between material” work pattern is adopted to reduce wear-resisting type and cost; adjust some impeller structure and craft. Comparing with the earlier equipment, the impeller lifespan is raise up by 30-200% on the situation of same material.
New lifting device to facilitate customer maintenance of the equipment, saving labor; minimalist design effectively prevent blocking when the moisture content of the raw material is high, reduce downtime, and efficient operation.
Equipment transmission parts special sealed cartridge bearing structure prevents leakage, won three national patents; good bearings, reduce transmission failure.
For the main frame, bevel gear device turns mainshaft. Shovels equipped on the main shaft throw materials between roller and ring, which can form material bed automatically. The material bed is crushed by centrifugal force which comes from grinding roller’s revolution, and then final powders are made successfully.
For the classifier, variable frequency motor turns cage-type rotor. Unqualified powder driven by gravity will return to chamber and be milled again, and qualified powder accompanied by airflow will come into cyclone powder classifier to be separated. Finally, final powders separated from airflow are collected.
When gas mixed with dust gets into powder collector, the motion of airflow changes from rectilinear motion to circular motion. Gas mixed with dust produces centrifugal force during rotating process, and the dust whose relative density is larger than gas’s will be threw at mill wall. Once dust touches mill wall directly, it will lose radial inertia force and falls along with mill wall until cone bottom under the action of downward momentum and downward gravity. When revolving airflow falls to cone, it will move toward center of dust collector because of conical contraction at the same time, with tangential velocity being higher and higher, dust driven by larger centrifugal force will be separated finally.
