Both of them have different kinds of models and some of them will be used as the coarse crushing jaw crusher machine.Being a manufacturer of jaw crusher machine, Zenith has produced the PE series jaw crusher and PEW series jaw crusher. The coarse crushing jaw crusher machine is defined by its discharging open size and feeding size ratio, such as the PE1000×1200 Jaw Crusher and PEW1100 Jaw Crusher is the typical coarse crushing machine in the rock stone production line.
All of the use need reduce the size of chromite by crushing.According to the statistics, in the output of the world chromite ore, 94% is the processed to the metallurgical grade chromite;2% is used for the chemical grade chromite;4% is the raw material of the refractory grade chromite and chromium cast iron. Therefore, the crushing equipment is significant in the chromite production flow.
Then there is a detailed description of the process. It aims to remove the unwanted impurity materials or gangues, improve the iron ore grade and refine the concentrate for final applications.Iron ore processing is a complex process from ore mine to ore industrial production, which including milling (crushing and grinding), washing, filtration, sorting, sizing, gravity concentration, magnetic separation, flotation, and agglomeration.
First of all, too much or too less of the lubricating oil will both cause the overheat of bearings. In this case, the bearings will overheat under high rotation speed operation. if there is too much lubricating oil, the produced heat cannot be radiated timely because the heat dispersion is not so good. While adding lubricating oil to bearings, the ideal quantity of lubricating oil is to occupy about 70% of the total space. If there is too less lubricating oil, then the bearings cannot be fully lubricated.
