First, an overview
Twin roll crusher (on roller crusher) is mainly composed of roll wheel assembly, support bearing, pressing and regulating device and driving device. The two roller wheels are respectively fixed on the two rotating shaft, the two ends of the shaft are provided with a set of bearing support, the fixed wheel is fixed on the machine frame, and the movable wheel is provided with a safety spring and a sliding bearing box. The movable wheel is used to adjust the gap that is the size of the finished product or when the two rollers fall into the metal debris, the movable roller can move horizontally, so as not to damage the equipment.
Two. The working principle and structure of the roller crusher:
1, the series of roller crusher is mainly composed of roller wheel, roller bearing, compression and adjustment device and drive device, and other parts of the composition.
2, the particle size of the adjustment: between the two roller wheel is provided with a wedge or gasket adjusting device, wedge device is arranged on the top of the adjusting bolt, when adjusting bolt wedge pull upward, the wedge block will activities and crown chakra from fixed wheel, namely two roll wheel gap larger, the grain size change, when the wedge block down, roll in the spring is compressed under the action of two gap smaller, the grain size smaller. Gasket device is by increasing or decreasing the number or thickness of the gasket to adjust the size of the material size, when the increase in the size of the two roller gap when the gasket is reduced, the gap between the two rollers becomes smaller, the size of the material becomes smaller.
3, the driving mechanism is driven by two electric motors, through the triangle belt drive to the roller wheel, according to the relative direction of motion rotation. In the crushing material, the material from the feed inlet through the roller, the rolling and crushing, crushing the finished product is discharged from the chassis below.
4, in order to be safe, the transmission part should be installed according to the actual situation of the safety cover.
On the installation of roller crusher (on the roller broken):
1, the installation of the roller should pay attention to the vertical and horizontal vertical.
2, the power line and control switch on the power distribution of the device.
5, the roller broken inspection is completed, the empty load test, the normal test can be carried out.
4, the roller breaking should be installed at the level of concrete foundation, fixed with anchor bolts.
5, after the installation of the roller to check whether the loosening of the various parts of the main gate and the main door is tight, if there is a fastener.
