Common failure of the wet ball mill
posted by jiandan .
Wet Ball Mill is the material being broken to smash the key equipment.By feeding, discharging part, turning part, a transmission of the main part.Mill widely used in cement, silicate products, new building materials, refractory materials, fertilizer, black and non-ferrous metal processing and glass ceramic production industry, for all kinds of ores and other materials may be grinding of dry or wet grinding.Ball Mill used for a long time, always more or less appear some problems.Our company based on years of experience for our customers to summarize the common problems in the ball mill.
First, the ball mill anti-blocking, leak-proof basic knowledge:The anti-blocking, we first need to check the sizes of materials and material feeding amount, if the delivery volume overload, can also cause the clogging of import.For the proof, we first check whether the imported seal wear, after a period of time will have leaked, we should timely replacement of packing seal.And we have the entrance position design discharge funnel and pipes, can be timely will leak slurry discharged into the trench.Second, Wet Ball Mill liquid pump speed adjustment:Through debugging during night cyclone station pressure test, to replace the slurry pump belt pulley.In third, ball mill imports and exports effects of abrasive material size:Ball mill control into the limestone particle size, in the scope of design.General Wet Ball Mill feed size of 80% particles of less than 12mm.Regulation of entrance feed mill.General to reduce electricity consumption, mill should be routinely maintained in rated operation conditions, but sometimes as a result of a variety of reasons, the steel ball added is not timely, then according to the ball mill main motor current to reduce properly reduce the feeding quantity, to ensure the qualified pulp particle size.In fourth, the ratio of ball mill to adjust grinding material size:To maintain a reasonable ball loading and the steel ratio.Limestone is on impact, extrusion and milled into slurry, if the ball loading capacity is insufficient, fineness will be difficult to meet the requirements.Running through surveillance of ball mill main motor current to monitor the steel balls loading, if it is found that the current decreased significantly to replenish ball.Ball mill in the first operation when the mass ratio should be according to the design of steel ball.Experience shows, ball supplement in general only the diameter of the largest models, because wear different diameter ball can be included in other types of columns.Can after running for a period of time according to the steel ball wear of ball, generally running 3 months after.
