About the Overflow and Lattice Type Ball Mill

The grid plate is a unique part of the lattice-type ball mill. Along with the center liner and the dustpan liner, it composes of the exhausting ore lattice.
The main functions of the lattice-type ball grid plate are as follows.
(1) Realizing the forced ore discharging of the grinding machine (also known as the low level ore discharging). The turnover of the ore material is quick, and the passing grinding is light, which is helpful to improve the capacity of the grinding machine.
(2) Having the effect of screening and preventing the bulk mineral aggregate and the grated medium from discharging. Notes: The hole on the lattice grid plate should meet the requirements of unobstructed discharge and not easy to be clogged. There are many orientations for the grating holes.
1) Concentric arrangement. The pulp flows along the lattice. If the lattice hole is worn seriously, the pulp will be reflux easily.
2) Radiation arrangement. At the moment of the mineral particles passing through the grid plate, owning to the centrifugal force, the mineral particles will move out along the hole, causing the congestion easily.
3) Tilting arrangement. This arrangement overcomes the shortcoming of concentric and radiation arrangement. Therefore, this kind of orientation gets widely adopted.
The advantages and disadvantages of lattice-type ball and overflow-type ball mill are as follows.
The advantages of lattice-type ball mill are that the ore exhausting speed is higher, reducing the phenomenon of over-crushing. At the same time, it increases the unit volume production, having a higher production than the overflow-type ball mill. Its disadvantages are that its structure is complex, easy to plug grid plate in ore exhausting process, its maintenance is difficult and complex, and operating rate is relatively low.
The advantage of overflow-type ball mill is simple in structure, easy to maintain. The disadvantage of overflow-type ball mill is low in production capacity per unit volume and easy to produce over crushed phenomenon.
