The FAG Programmed Grinding

Cement grinding process is the key step in the cement manufacturing line. In the cement grinding process, limestone, coal, gypsum and need to be grinded into powder by grinding equipment cement clinker. At present, most of cement production plant is mature in the technology of bag filter and electrical precipitation and all of them can reach the country s requirement for dust emission. However, as soon as you perceive, it shows that environment has been seriously damage. Environment has a negative effect on the quality of life, healthy life and human activities. So it is very important to choose the crushing and grinding machine, because limestone is high hardness material, and it can be crushed by DPC single stage hammer crusher, which specially used for the rigor condition of limestone abrasive, at last screened by vibrating screen.

At this time materials which match the desired size go to the next step grinding, materials which don’t meet the size go back and continue to crush, until reach the required size. Cement is made from lime stones and clay through calcination at high temperature. In the cement production process, most of the materials need to be crushed, such as limestone, clay and mine, etc. The biggest quantity of pipes is limestone, whose size is large and hardness is high after exploitation, so it is very important to crush limestone in cement production process. In cement production, most of the materials need to crusher. Limestone takes a large proportion in cement processing, and has high hardness and large particles, so it also need to be processed by crusher.

Stone manufacturing line is generally: hopper-vibrating feeding machine-DPC single stage hammer crusher-screening equipment-final production.As the professional manufacturer of complete sets of mining machinery, such as flotation cells, Henan Hongxing is always doing the best in products and service. The stone manufacturing line in every cement production plant is similar, however the final materials is stone powder, so it must add the step of grinding process in cement manufacturing plant. While crushing process is more economic and convenient than grinding process. The large-block materials should be crushed to tiny and even size as possible as they can before entering milling machine, in order to alleviate the load of milling machine and increase the output of milling. Meanwhile it can lighten the segregation phenomenon in varying degrees in transportation and storage, raising the accuracy of ingredient after pipes crushed. Rotary kilns are usually radically supported in hydrostatic bearings. However, for some years now, support roller units with rolling bearings have also been used, fig. 22 The FAG Programmed product includes such units. Axial support of the rotary kiln is always affected by support rollers (fig. 23) which in turn are supported in rolling bearings. FAG, ACE to rolling bearing manufacturer, you have to prepare for the growing demand for bearings used in machines for cement production. Cement producer plants are usually erected near huge limestone deposits. If the geological structure of the limestone is not homogeneous, additives must be admixed during the preparation process. Limestone deposits are virtually inexhaustible so that the availability of this raw material for cement in the future is ensured.
