The utility model content
For defects, the technical problem that the utility model solves is to provide a kind of four-roller crusher, and broken raw meal particle size is even, and granularity is less.
In order to solve above technical problem, the four-roller crusher that the utility model provides comprises left socle and right support, and described left and right support respectively is equipped with a pair of roller up and down; Each pair of rollers comprises drive roll and driven roll, be divided into drive roll, upper driven roll, lower drive roll and lower driven roll, its transmission group becomes upper active motor and connects reductor by shaft coupling and drive drive roll, driven roll under the large wedge belt wheel of the other end of upper drive roll drives by the wedge band; Lower active motor connects reductor by shaft coupling and drives lower drive roll, drives driven roll by the wedge band at the little wedge belt wheel of the other end of lower drive roll and rotates.
Preferably, described upper drive roll is arranged on the top of described support, and described lower drive roll is arranged on the bottom of described right support.
Preferably, upper drive roll and the gap between upper driven roll on described support top are 6mm-10mm.
Preferably, the lower drive roll of described support bottom and the gap between lower driven roll are 2mm-4mm.
Preferably, the radius ratio between the wedge belt wheel of the wedge belt wheel of described top a pair of roller and following a pair of roller is about 2: 1.
Preferably, described on, the bearing block two sides of lower driven roll respectively are provided with a hydraulic thrust cylinder, altogether four hydraulic cylinders.
Preferably, the hydraulic system of described hydraulic thrust cylinder is provided with the synchronous valve device.
Preferably, the roller epidermis surface build-up welding of described upper drive roll and upper driven roll has wear-resisting alloy electrode.
The four-roller crusher that the utility model provides, mainly comprise the chassis, the left and right support, each a pair of roller sections and top cover up and down, each pair of rollers comprises drive roll and driven roll, is divided into drive roll, upper driven roll, lower drive roll and lower driven roll, its transmission group become upper active motor and connect reductor by shaft coupling and drive drive roll, driven roll under the large wedge belt wheel of the other end of upper drive roll drives by the wedge band; Lower active motor connects reductor by shaft coupling and drives lower drive roll, drives driven roll by the wedge band at the little wedge belt wheel of the other end of lower drive roll and rotates, thereby guarantee that upper pair of rolls rotor speed is identical, and the rotating speed of next pair of rollers is also identical.Drive roll is fixed, driven roll is the synchronous pushing of hydraulic thrust cylinder that always is installed in its Y-axis bearing same side, thereby guarantee that the gap between a pair of roller is constant, and the gap length between two pair of rollers of up and down is different, and the gap between next pair of rollers of Gap-Ratios between upper a pair of roller is large.Compared with prior art, the four-roller crusher that the utility model provides by twice fragmentation of up and down two pair of rollers, reaches the broken purpose that raw meal particle size is even, granularity is less.
In addition, the four-roller crusher that the utility model provides, on, the bearing block two sides of lower driven roll respectively are provided with a hydraulic thrust cylinder, altogether four hydraulic cylinders; The hydraulic system of hydraulic thrust cylinder is provided with the synchronous valve device.Because hydraulic thrust cylinder has good stable characteristics, reciprocal synchronism is good.
Especially, the four-roller crusher that the utility model provides, the roller epidermis surface build-up welding of upper drive roll and upper driven roll has wear-resisting alloy electrode, can extend the service life of roller.
