Roll tooth
The crushing roll is made of an abrasion-resistant and corrosion-resistant high manganese steel. The roll teeth are laid in a staggered arrangement, making the crushing process more efficient.[/vc_column_text][vc_separator style=”dashed” border_width=”2″ el_width=”90″ css=”.vc_custom_1610470004936{padding-top: 20px !important;padding-bottom: 20px !important;}”][/vc_column][/vc_row][vc_row][vc_column width=”1/2″][vc_column_text]
Scraper device
The mud scraping device is made of wear-resistant materials. It prevents materials from sticking to the rolls, thus ensuring an effective tooth height and suitable gap for materials to pass through. This also ensures proper braking and pressing strength.[/vc_column_text][/vc_column][vc_column width=”1/2″]
Hydraulic system
The hydraulic system is used to adjust the crushing roll tooth gap to meet the different requirements for particle size discharging.[/vc_column_text][/vc_column][vc_column][vc_separator style=”dashed” border_width=”2″ el_width=”90″ css=”.vc_custom_1610470004936{padding-top: 20px !important;padding-bottom: 20px !important;}”][/vc_column][/vc_row][vc_row][vc_column width=”1/2″][vc_column_text]
Lubrication system
Using a lithium base grease, the lubrication system is powered using a specialized motor so that the oil feeding speed from the pipeline to each lubricating point is regulated.
The four spindles can not only be lubricated individually but also simultaneously, thus ensuring they are easy to maintain.[/vc_column_text][/vc_column][vc_column width=”1/2″]
V-belt tensioner
When any material that can’t be crushed enters the chamber, the movable roll will quickly move backward, and the V belt will be loosened. The belt will not slip or become twisted due to the elastomer action in the tensioning device. The elastomer is produced by ROSTA and features stable performance and long service life.[/vc_column_text][/vc_column][/vc_row][vc_row css=”.vc_custom_1610441187054{padding-bottom: 60px !important;}”][vc_column][vc_text_separator title=”Characteristics” border_width=”3″ css=”.vc_custom_1610470279950{padding-top: 20px !important;padding-bottom: 20px !important;}”][vc_column_text]
- Under the joint action of pressure and shear force, the material is jammed and crushed between two opposite rotating rolls, then is discharged from the gap between the roll teeth. If any material sticks to the roll surface, it is removed using the scraper.
- The machine frame design allows the moving roll bearing seat to move horizontally along the slide. If an object cannot be crushed in the roller, the roll will move backward and discharge the foreign material to protect the equipment against damage.
- The flexible resin curtain prevents viscous material with water content from sticking to the crushing chamber’s inner surface.
