The concept and the main uses of Wet ball mill: Ball mill machine is the material to be broken, and then to smash the key equipment,ball mill is widely used in industrial production of high-fine grinding machine, applicable grinding all kinds of ores and other material.Widely used for ore dressing, building materials, chemical and other industries, can be divided into two kinds of dry and wet grinding methods. According to different ways of discharge can be divided into two kinds of lattice type and Overflow. Wet ball mill's applicable scope: Ball mill is the material to be broken, and then to smash the key equipment. It is widely used in cement, silicate products, new building materials, refractory materials, fertilizer, glass, ceramics and other non-ferrous mineral processing and manufacturing industries, a variety of ores and other grind-able materials can be dry or wet grinding. Wet ball millequipment installation test machineThe ball mill installation is complete, after passing test, and then empty car test run.The ball mill's trial operation of ball mill by skilled operators shall be responsible for ball mill, and strictly abide by rules of safe operation.1. Idle running of continuous operation time not less than 12-24 hours, identify problems in operation should be promptly addressed. 2. Idle operation commissioning normal can undertake load test run.load test run should be in phases. Load operation should inspect discharging situation to carry on the feeding,to avoid steel ball and cylinder liner board unnecessary grinding and damage.a. With suitable materials and 1/3 number of steel ball (the maximum amount of ball see ball mill main layout) test run 12-24 hours. b. Added to 2 / 3 of the number of balls running 24-48 hours. c. According to the ball mill discharging, the output of qualified products, referring to the actual outfit similar concentrator ball mill is measured, decide this set reasonable quantity loaded ball mill, less than 72 hours of step trial operation. 3. The load increases and commissioning the length of time, with size and gear reducer gear running-in conditions (temperature, noise, gear surface contact, etc.) as the basis for sure.4. commissioning of cooling and lubrication system should be working normally. The main bearing, transmission bearings, reducer temperature should be normal.5. Load 2/3 number of steel ball test run 24-48 hours, should check and tighten all bolts again.6. Commissioning work to do a good job of the record. Wet ball millequipment working principleThis machine is a horizontal cylinder rotating mechanism, outside edge gear transmission, the two storehouse, lattice-type ball mill.Material from the feed device into the compound by the air shaft into the mill screw evenly the first warehouse, there are ladder liner or corrugated liner in the warehouse,inside pack different specifications ball, rotating cylinder produces centrifugal force to the ball fall a certain height, For material produce crits and abrasive. Material in the first storehouse reach coarse grinding, the single-layer diaphragms enter the second storehouse, the warehouse are lined with flat lining, the steel ball, contains material is further grinding. The powder discharged through the discharge grate plate to complete the grinding operation. Wet ball millequipment structure characteristics: The ball from the feeding part, discharging Department, Rotary Department, the Ministry of transmission (reducer, small transmission gear, motors, electrical control) and other major components. Hollow shaft adopts steel castings, lining can removable, rotary gear with cast roll teeth processing, the cylinder body inlaid cylinder liner wear, has the good abrasion resistance.
