Ball mill causes and impact corrosion wear

Nov 9th 2015 at 1:32 AM



Ball mill complete the Ball Mill Liner Plate exporters grinding operation is the primary site of action, it occupies a very important position in the ball mill grinding operation, so wear and corrosion resistance of Hongxing ball mill machine has been attached great importance. Below to analyze the cause of corrosion and wear ball impact.

First, look for a Grinding Steel Media Ball understand the ball in a ball mill is how it works. Ball Mill is a circular cylinder, the cylinder at both ends with end caps with a hollow journal, the cover of the journal is supported on bearings, the motor through a gear mounted on the cylinder rotating ball mill, in the cylinder body equipped with grinding media (balls, steel bars or gravel, etc.) and the grinding of ore, the total loading capacity of 25 to 45% effective volume of the cylinder. When the cylinder at a predetermined speed of rotation around the horizontal axis, the cylinder body and ore grinding media by centrifugal force and friction, the cylinder liner is raised to a certain height, then spilled down from the cylinder wall or free throw fall, impact and grinding the ore stripping and grinding.

Ore from the barrel end of the hollow journal continue to give in, and after Forged Grinding Ball suppliers grinding products continue to discharge through the hollow cylindrical spigot the other end of the cylinder body movement is the use of mineral ores have given into pressure to achieve. When wet milling, ore flow was taken away. When dry grinding, ore is extracted airflow to the outer cylinder away.When material effect on the ball mill in the ring or corrosive activity, also causing corrosion and mechanical wear accessories ball loss, and have mutually reinforcing effects. Ball mill loss generated in this condition, often referred to as corrosion and wear. In the corrosion products produced after ball mill friction surface material and chemical or electrochemical reaction, generally combined with maternal surface is weak, and when the ball mill surface materials interact, corrosion products can easily be worn, bare new metal surface, provided the conditions for the further corrosion. Thus, corrosion - and wear - corrosion alternately proceed, it will generate higher than dry grinding of metal loss.
