The grinding roller is a device that puts pressure on the material and crushes it on the grinding table. Under constant pressure, the grinding roller’s shape and size have a direct impact on the grinding efficiency of the material.[/vc_column_text][/vc_column][vc_column width=”1/2″]
Forced oil lubrication is utilized and the system enables temperature monitoring.[/vc_column_text][/vc_column][vc_column][vc_separator css=”.vc_custom_1611997119929{padding-top: 20px !important;padding-bottom: 20px !important;}”][/vc_column][vc_column width=”1/2″][vc_column_text]Rocker arm
The rocker arm is a component that connects the grinding roller and tension device. The pulling force produced by the hydraulic cylinder is transferred from the rocker arm to the grinding roller.[/vc_column_text][/vc_column][vc_column width=”1/2″]
There is a lining plate installed on the grinding table. The surface of the grinding mill is made using wear-resistant materials formed using a weld overlay, and can be re-welded after abrasion build up and reused, thus improving the service life of the lining plate[/vc_column_text][/vc_column][vc_column][vc_separator css=”.vc_custom_1611997475019{padding-top: 20px !important;padding-bottom: 20px !important;}”][/vc_column][vc_column width=”1/2″][vc_column_text]Housing
The coal grinding mill housing has three parts: the lower housing, the middle housing, and the separator’s housing, and they are welded into place.[/vc_column_text][/vc_column][vc_column width=”1/2″]
The tension device includes a hydraulic station, hydraulic cylinder, accumulator, and pipeline. The hydraulic cylinder is pressurized in both directions. When the coal mill starts or stops feeding during operation, the grinding roller can be raised by reverse pressurization to achieve no-load start and no-load maintenance.[/vc_column_text][/vc_column][vc_column][vc_separator css=”.vc_custom_1612094267651{padding-top: 20px !important;padding-bottom: 20px !important;}”][/vc_column][vc_column width=”1/2″][vc_column_text]Separator
The separator completes the sorting process by a vortex plane, making the powder selection efficiency high. The transmission adopts an AC motor with variable frequency speed regulation so that the operator can adjust it conveniently according to different requirements such as product fineness and production status.[/vc_column_text][/vc_column][vc_column width=”1/2″]
The mill frame is the basic frame of the entire coal mill, and the columns and reducers are located on the frame to become a whole. The base frame is welded from profiled steel and has an adjustment mechanism to adjust the frame’s level conveniently.[/vc_column_text]
The drive consists of a mill reducer, a diaphragm coupling, the main motor, and a gear reducer, etc.[/vc_column_text][/vc_column][vc_column width=”1/2″]
Theeeding device mill’s feeding devicets a a rotary feeder, which has the advantages of simple airtight structure, stable operation,, and continuous feeding. The wear-resistant liner of the housing is machined metal, featuring high precision; the gap between the blade and the wear-resistant scraper is adjustable, both of which are wearing parts and can be replaced. Hot air enters through both sides of the housing to prevent the feeder from clogging.[/vc_column_text][/vc_column][vc_column][vc_separator css=”.vc_custom_1612094765984{padding-top: 20px !important;padding-bottom: 20px !important;}”][/vc_column][vc_column width=”1/2″][vc_column_text]Turning device
Each grinding roller is supported separately, and the overhaul door on the middle housing can be opened during examine and repair. The grinding roller can be easily turned out of the coal mill by the hydraulic cylinder, and the roller sleeve can be easily disassembled and removed for convenient overhaul and maintenance.[/vc_column_text][/vc_column][vc_column width=”1/2″]
The main valves and oil pumps use the world’s famous brand. The hydraulic system is equipped with a double cylinder filter. The normal operation vibration of the equipment can be controlled within < 1.5-2.0 mm/s. The fluctuation of system can be effectively reduced to avoid damage or efficiency loss caused by grinding roller fault or strong vibration.[/vc_column_text][/vc_column][vc_column width=”1/2″]
