Processing Weight: 545T. The ball mill trunnion, also known as the hollow shaft is an important part of the ball mill that carries the rotation of the ball mill barrel. It is a special type of steel casting. It mainly plays the role of supporting and connecting the cylinder in the whole ball mill, and is the entry and exit channel of the material.
Cement Manufacturing Process Phase 1: Raw Material Extraction. Cement uses raw materials that cover calcium, silicon, iron and aluminum. Such raw materials are limestone, clay and sand. Limestone is for calcium. It is combined with much smaller proportions of sand and clay. Sand clay fulfill the need of silicon, iron and aluminum.
The working principle is that cement is removed from the mill before overgrinding has taken place. The cement is then separated into a fine fraction, which meets finished product requirements, and a coarse fraction which is returned to mill inlet. ...
