To cement mill is an installation used to grind the clinker component of concrete. Clinker is a hard, nodular material produced by sintering aluminosilicate and limestone in a cement kiln. There are several cement mill types which are able to grind clinker of which the ball mill is the most common. Ball mills consist of cylinders partially filled with large numbers of steel balls which employ their rolling action to crush the raw material when each cylinder is rotated. High pressure roller mills are occasionally used to grind clinker although their use has not yet gained broad acceptance. Generally, cement plants often choose dynamic pressure lubricating method, which is major I will discuss in this article. At first, we should choose proper lubricating oil as well as additives, so that improve milling machine lubricating condition. The work features of cement mill bearing are large overload and linear velocity, suffering from impact and vibrating; the size of bearing bush and hollow shaft is also big, the improvement of shape, size, accuracy and smooth degree are HA by manufacturing conditions.
Therefore, main bearings do not guarantee total liquid lubrication, but in boundary lubrication conditions. Excellent boundary lubrication (depending on the performance and strength of boundary film) can significantly reduce the coefficient of friction, reduces bearing wear. Specialized in producing all kinds of dry ball mill, cone ball mill, energy-saving ball mill, prices and other processing equipment, energy saving, energy saving, saving ground. cement ball mill pulverizing system is a multi-variable time delay, multivariable coupling and time-varying characteristics of the charged object, rotary kiln the control system of the past three independent conventional PID control system, it is difficult to consider system the specific characteristics of the powder system, such as to eliminate the mutual interference between the circuit and to overcome delay time variability of the object. Cement ball mill is widely used in thermal power plants at home and abroad, brick making machine but there are still some urgent problems in use, such as the entire milling process difficult to achieve automatic control, but can not run in the best economic output state.
