The ball mill is key equipment for re-crushing materials after being primarily crushed. Ball mills have been widely used in a wide range of materials such as cement, silicate, new type building materials, fireproofing, chemical fertilizer, black and non-ferrous metal and glass ceramics. Ball mills can realize dry type or wet type grinding for all kinds of ores and other grindable materials. After installation and inspection, trial operation without load should be carried out by skilled operators who strictly abide by safe operation rules.
When choosing the grinding body of ball mill, we need to consider a lot of factors. However, the selection and application of high abrasion resistance grinding body is obviously beneficial to the grinding effects of ball mill. Next, let's see the concrete conditions together.
The surface of grinding body made of high abrasion resistance material is so slippy that the materials in grinding process are not blocked and buffer phenomenon dramatically reduces. In addition, the flow rate of interstice formation caused by materials' going through the grinding body is pretty high. Thanks to the two reasons, the output of ball mill is greatly increased. Since more products are produced with the same electric quantity, electricity is also saved.
The high abrasion resistance grinding body has the following features: high hardness, good abrasion resistance, less deformation possibility, stable grading, high yield, long service life, and relatively low grinding cost. Therefore, the frequency of adding balls and cleaning obviously reduces, labor intensity lessens and the operating efficiency of ball mill is accordingly improved.
The grate ball mill is a horizontal cylinder rotating device driven by gears with two silos. The materials get into the first silo through the feeding quill shaft from the feeding device spirally and evenly. There are ladder lining board and corrugated lining board in the first silo loaded with steel balls of different sizes. The centrifugal force produced by the rotation of the cylinder raises the steel balls to a certain height which then fall down, thus making thumping and abrading to the materials. After the coarse grinding in the first silo, the materials get into the second silo through the monolayer partition panel with flat lining board embedded with steel sections for further crushing. The powder of the materials will be discharged from the unloading board to finish the grinding work.
The ball mill is mainly composed of feeding mouth, discharging mouth, rotary part, transmission part (reducer, small transmission gears, engine and electric control device). The hollow shaft is made of cast steel and the interior lining board is changeable. The big rotary gear is fabricated with the casting gear hobbing. This machine operates smoothly and reliably.As a professional and the best mining machinery manufacturer in China, Hongxing Machinery is always ready to provide the superior concrete crushing machine, cement equipments, and these machines have the most competitive price and the most reliable quality so that they are the top choices for the high performance crushing equipment.
