Φ 6.2m× 9.5m (F/F) Overflow Ball Mill And Supporting System With Fully Functional
1. Overview, basic conditions
(1) Overview
Ball mill is the key equipment for material crushing after being crushed. This type of mill is in its cylinder body into a certain number of steel balls as grinding medium.
It is widely used in cement, silicate products, new building materials, refractory materials, chemical fertilizer, black and non-ferrous metal dressing and glass ceramics and other production industries, dry or wet grinding of all kinds of ores and other grindable materials. Ball mill is suitable for grinding all kinds of ore and other materials, is widely used in mineral processing, building materials and chemical industries, can be divided into dry and wet grinding two ways. According to the different way of ore discharge, it can be divided into two types: lattice type and overflow type.
(2) Geographical and meteorological conditions
For indoor installation, the altitude is less than 1000m.
(3) Rotation of the mill
Right-hand rotation
Rotation interpretation: from the feeding end to the discharging end, the main motor is on the right.The main motor is at the discharging end.
(4) Work System
Continuous work 330d/a, 24h/d, 3 shift /d, 8h/ shift.
(5) Power Supply Conditions
Power supply: high-voltage three-phase four-wire 10kV, output voltage range 10kV±10%, low-voltage three-phase four-wire 380V, frequency 50Hz.
(6) Water Supply Conditions
Water quality: neutral and clean circulating water;Water temperature: ≤30℃;Water pressure: 0.3 ~ 0.4mpa.
