Info of MB5X158 Pendulum Suspension Grinding Mill:

OUTPUT SIZE: 0.045-0.18mm


According to accumulation and experimental analyses of on-site product test data for more than thirty years, Kefid has researched and developed the fifth-generation pendulous hanging grinding mill – MB5X pendulous hanging grinding mill with many invention patents. It represents the most advanced grinding processing technology at present, and it is the optimum choice for upgrading and updating. All non-combustible and non-explosive brittle mineral products whose Moh’s hardness are below Grade 7 and water content below 6% could all be ground.MB5X158 Pendulous Suspension Grinding Mill is specific for processing non-metallic minerals.


Feldspar, calcite, limestone, talc, barite, rare earth, marble, bauxite, phosphate ore, iron oxide red, dolomite, granite, bitumite, anthracite, lignite, kaolin, bentonite, gypsum, etc.



1.Thin oil lubricating grinding roller device, low maintenance cost. Grinding roller device adopts thin oil lubrication, which is a technology initiated domestically, and it is maintenance-free and easy to operate.
2. Cancel shovel blade cylinder structure, improving the grinding efficiency. The increased chamber space will allow bigger roller diameter, thus increase the grinding pressure. Besides, larger vent area will reduce wind resistance.
3.Volute elastic damping structure improve the stability of the equipment. MB5X158 Grinding Mill is different from other grinding plants which has rigidity connection by bolts between volute and bed. This new mill adopts damping structure with thickened rubber mat, which avoids damage by vibration of volute and airframe and reduce vibration of classifier.
4. Diluted oil lubricating method realizes excellent stability performance of equipment. The main-shaft bearing, transmission-shaft bearing and gear engagement surface are all supplied with cyclic oil lubrication and heat dissipation by built-in oil pump with automatic operation ever without manual operation, which can timely and effectively ensure operating stability of the host.
5. New-type cage powder concentrator, low power consumption of the system. Powder concentrator applies low-resistance hanging cage powder concentrator, which is of narrow grain-size sorting, high sorting efficiency, low system energy consumption, and under condition of equal materials and fineness, it is of lower power consumption and higher productivity than blade-type powder concentrator.
6. Efficient powder collector, improving service life of equipment. The use of large-diameter powder collector and bottom pneumatic wind lockage valve could effectively improve powder-collecting efficiency, and avoid powder-returning phenomenon; air intake of the powder collector applies wear-proof liner for fitting, which has directly improved the service life.
