When talking about the ball mills, it involves the steel balls or even the hard pebbles which can break them into fine particles which are purely based on the impact as well as the attrition. A rotating mill comes with the charging with the media and the ore in this is lifted against the perimeter which is present inside of it. Some of the media that are being charged by the rotating mill fall and it impacts the particles of the ore that are located at the bottom of the mill. The rest of the media which is left is made to cascades and, in this process, it can create the breaking of the particle with the help of the attrition.
Types of mill liners present in the market
There are a total of six types of mill liners that are popular in the market and are also high on the demand.
● Ripple Liners: Talking about the first one is the ripple liners in which the system of the grinding is the small section that consumes the power mostly present in the processing plant of the mineral. It is responsible for up to 40% of the total consumption of the power in the processing plant operations related to the minerals. So, the selection of the solution which is efficient in nature for the section of the grinding is found to be very important in the mill liners. The providers that look promising usually provide the system of grinding of the ball mill or even the rod mill which is widely used in various types of mineral extraction and has also found its popularity in the electricity, cement, and chemical industries. It can carry out the crushing of either the dry or the wet and is also capable of meeting the demand for sustainable production at a large scale in the mill liners.
● Rod Liners: Out of all the cast materials being used for the linings are the Nickel hard, steel made up of the chrome – molybdenum, and along with that the steel which is made up of the manganese. The steel plate which has rolled the steel over it has the lifter bats available with it. The rod liners are made to have exposed to the impacts of the severe level. For the duty of grinding, the right selection of the liners is necessary and for that premature breakage is considered.
● Shiplap Liners: The shiplap liners are nothing but the plates that have the longitudinal lining for the ball mill in the mill liners and are available in the shape of the wedgelike. The edge which is thin in the density of each wedge lies beneath the edge which is thick in density and it belongs to the preceding plate which is in the direction of revolution. The shiplap liners are simply the liners that get attached to the form that is using the screws of the TEK with the help of the face of the linear spacing of about 12” C-C.
● Lifter bars: When the lifter bars are taken as a liner, they are used for the protection of the head of the ball mill in the mill liner from direct impact and along with that the friction is also avoided which is caused by the grinding medium and correspondingly the material. This kind of Mill Liner is found to be excessive in use in all kinds of working conditions so that it can increase the efficiency of the grinding and along with that the production and it might be proved as a reduction in the consumption of the metal.
