Construction method for back lining materials of ball mill

Abstract

The present invention discloses a construction method for back lining materials of a ball mill. The construction method is characterized in that the method includes the following steps: first, bottom lining materials are respectively laid at the joint position of each lining plate along the axle line when the lining plates are installed; second, after the lining plates are completely installed, the back lining materials are poured at the crack positions of each row of lining plates from the bottom part of a cylinder body and each row of lining plates are sealed by clay after the pouring is finished; third, the back lining materials are poured from the next row of lining plates to the bottom part of the cylinder body after the cylinder body is moved, and the sealing is carried out by the clay after the pouring is finished; and the above steps are repeated until the pouring of all the lining plates is finished. The advantages of the invention are as follows: (1) the flowing distance of the construction method for pouring the materials is short; (2) the filling rate is high; (3) an auxiliary safety facility is not needed when in pouring due to high safety factor, but in the prior art the auxiliary safety facility is needed to support the lining plate at the top part after the lining plate is installed halfway; (4) the construction method has short construction period and needs about 8 hours, but the pouring of one ball mill in the prior art needs almost 10 days; (5) the construction method needs low cost and adopts the clay for sealing, but the cement is used for sealing in the prior art.

Description

technical field [0001] The invention relates to a construction method of a ball mill backing material. Background technique [0002] At present, ball mill backing materials are widely used. The backing of the ball mill is to inject a kind of polymer material between the cylinder and the liner of the ball mill to improve the bonding degree of the liner and the cylinder. However, due to problems with the construction method, there are factors such as long construction period, low safety factor, large waste of materials, and low filling rate of pouring materials, which have adverse effects on equipment operation. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a construction method for the backing material of a ball mill to overcome the shortcomings of the prior art such as long construction period, low safety factor, large material waste and low filling rate of pouring materials. [0004] The invention adopts the...
