The crushing of ore is a large ore. By means of the action of external force, it overcomes the internal intermolecular force and breaks, so that the size of the nugget is gradually reduced. In the ore dressing process, ore crushing is usually divided into two major stages: crushing ( coarse stage ) and grinding ( fine stage ) .
In the concentrator, the crushing of the ore is an indispensable material preparation stage before the sorting operation. First, most of the ore processed by the concentrator is closely associated with useful minerals and gangue minerals, and often in fine or even fine-grained inlays. Only by breaking them down and fully dissociating them can they be enriched by existing physical beneficiation methods. Second. All physical beneficiation methods are limited by particle size, and the particle size is too coarse
(the useful mineral and the gangue are not dissociated
) or the fine particle size
( ie, the over-pulverized fine particles
) cannot be effectively sorted.
In all aspects of the concentrator, ore crushing is the most expensive process and an important part of the investment and production costs of the concentrator. According to statistics, the investment in ore crushing process accounts for about
60 % of the investment of the ore dressing plant. The production cost accounts for
40 %
-60% of the total cost of mineral processing, the electricity consumption accounts for
50 %
-65 %, and the steel consumption accounts for
more than
50 %.
In summary, the basic task of the ore crushing operation is to provide suitable materials for the sorting operation. The crushing process works well and directly affects the technical and economic indicators of the beneficiation, so some people think. Ore crushing is the key to determining the success or failure of the beneficiation process. Therefore, each ore dressing worker should pay sufficient attention to the process equipment selection and production management of ore crushing operations.
Tower Crane Cabin
Tower Crane cabin is the control center of the crane and is attached to the slewing unit. In order to get to the tower crane cab, the operator must climb a series of ladders within the mast.
The movement of the tower crane is controlled from the operator`s cabin. Within the tower crane cabin, you`ll find the operator`s chair with joystick controller, electronic monitoring devices, and communication systems. Many cabins come with climate control to ensure a comfortable work environment. The Operator Cabin for Tower Crane is part of the slewing assembly.
