Description
Technical field
The utility model relates to large-size ball mill steel ball pack completeness detection technique field, particularly a kind of large-size ball mill steel ball pack completeness pick-up unit.
Background technology
Large-size ball mill is a visual plant in the iron ore concentrate production run of mine, and its power consumption is huge.And how many steel balls of ball milling internal stowage directly influences the efficient of bowl mill ore grinding; Therefore; In actual production; Accurately measure steel ball pack completeness in the bowl mill, and rationally add the ore grinding steel ball to improving ball mill efficiency and grinding machine usage factor, and saves energy, the loss of reduction each item have played vital role.
Large-size ball mill is divided into two kinds of lattice type and overflow types, generally adopts overflowball mill, when measuring overflowball mill steel ball pack completeness; Because water covers steel ball in the bowl mill; Can't see with the naked eye how many steel balls has in the bowl mill, so the method for manual measurement is generally adopted in the ore dressing plant, promptly the operator gets in the bowl mill through the mine-discharging terminal viewport; With the bamboo pole of band scale, measure the distance of steel ball surface to water surface in the bowl mill.Through the measurement to the multiple spot depth of water in the bowl mill, manual calculation draws the mean depth h of each measurement point then, uses formula: pack completeness=50-127 (h+ antispin the internal diameter)/effective internal diameter of bowl mill (unit: mm), finally calculate the pack completeness of steel ball in the bowl mill.
This method requires the operator must get in the bowl mill; Because after bowl mill stops; Vapor (steam) temperature is up to more than 100 degrees centigrade in the bowl mill, and the operator can't get at all in one hour, and the process of the manual measurement depth of water also needs one hour; Have a strong impact on the operating rate of bowl mill, restricted production.
Along with the maximization of beneficiating and grinding ore equipment, ball mill barrel is very long, and bowl mill parking back is bigger to the range difference distance of steel ball surface to the water surface of ore deposit end and mine-discharging terminal; Because the ball milling built-in temperature is high, environment is abominable, complicated, the depth of water; Mud carefully glues, and the operator is difficult to go to the ore deposit end and goes to measure in order to guarantee safety; Cause measuring result error very big, the pack completeness result who calculates is not accurate, is unfavorable for improving ball mill efficiency.
Summary of the invention
