Price Used Ball Mill Cement

As a common ore dressing and grinding equipment, ball mill is popular among investors.To meet the needs of different industries, different types of ball mills gradually appeared.This article will introduce several commonly used ball mills and their differences.Investors can choose appropriate ball mill according to your own needs.

According to the curves shown in figure 1 characteristics can be seen.The noise signal is ball mill can reflect the quantity of materials.In the ball speed constant, the ball is a certain period, by measuring the grinding machine, the noise signal can be directly within the ball mill detection of materials.Therefore, the stability of the grinding machine for shoes.Control air purging, make their relationship, it can control the equilibrium of the grinding mill.

The liner made of ordinary material is too thick, which will reduce the effective volume of the ball mill cylinder.Besides, thick liners increase power consumption due to the large weight and reduce the production efficiency of the ball mill.So how to choose a hard material to make thin but durable liner is an important issue.

Mills with unloading through the grid have a lifting device and it forced to unload the milled product.Therefore, in this type of mills the slurry level may be lower than the unloading trunnion level.Mills with unloading through the grid sometimes called mills with forced unloading or mills with a low level of pulp.This type of ball mill has a grid with openings for unloading crushed material and located in the unloading end of the drum.The grid has radial rib-lifters on side facing to the unloading end cover.Rib-lifters divide the space between the grid and the end cover on a sectorial chambers opened in the trunnion.By rotating the drum ribs act as elevators wheel and raise the pulp to the level of unloading trunnion.This device allows to maintain a low pulp level in the mill and reduces the spent time of the material in it due to the decrease of volume of the pulp.

The bond ball mill work index can be used in the design calculations and simulations using jksimmet of a new grinding circuit.A bond ball mill work index may also be used in the simulation and optimisation of existing mill(s) and the associated grinding circuit(s).
