Ball Mill Overview
Ball mill is an efficient tool for grinding many materials into fine powder. The Ball Mill is used to grind many kinds of mine and other materials, or to select the mine. It is widely used in building material, chemical industry, etc. There are two ways of grinding: the dry process and the wet process. It can be divided into tabular type and flowing type according to different forms of discharging material.
Ball Mills are primarily used for fine grinding. Ball Mill is key equipment which repulverises the material after it is crushed. Ball Mill is widely used in powder-making production line including cement, silicate, new-type building material, refractory material, fertilizer, ore dressing of ferrous metal and non-ferrous metal, glass ceramics, etc.
Our company has been amongst the pioneers for many years in the design and application of milling systems for the size reduction of a wide variety of materials including minerals, ores, and coal.Working Principle
The ball mill is a horizontal rotating device transmitted by the outer gear. The materials are transferred to the grinding chamber through the quill shaft uniformly. There are ladder liner and ripple liner and different specifications of steel balls in the chamber. The centrifugal force caused by rotation of barrel brings the steel balls to a certain height and impact and grind the materials. The ground materials are discharged through the discharging board thus the grinding process is finished.
Ball Mill Features
1. This ball mill is horizontal type and tubular running device, has two warehouses.
2. This machine is grid type and its outside runs along gear. The material enters spirally and evenly the first warehouse of the milling machine along the input material hollow axis by input material device.
3. In this warehouse, there is a ladder scaleboard or ripple scaleboard, and different specification steel balls are installed on the scaleboard, when the barrel body rotates and then produces centrifugal force, at this time, the steel ball is carried tosome height and falls to make the material grinding and striking. After grinded coarsely in the first warehouse, the material then enters into the second warehouse for regrinding with the steel ball and scaleboard.
4. In the end, the powder is discharged by output material board and the end products are completed.Ball Mill Specification
