A support device and a high-speed pulverizer having the support device are disclosed. The support device includes an outer casing. The outer casing has a mounting cavity therein. A bearing is retained in the mounting cavity through a sealing member. The sealing member is a movable structure that is flexibly connected, which realizes automatic centering in the working process, improves the service life of the bearing and the sealing member, and realizes the effect of vibration reduction and noise reduction.

A work machine having a belt tensioning system is described. A belt is engaged with an engine drive sheave and a driven sheave of a rotor having a plurality of cutting tools configured for reducing wood infeed material. An idler pulley is mounted to an idler arm that is hinged to the machine frame. An actuator is hinged to the idler arm and the frame. The actuator may be extended and retracted in order to press the idler pulley into stronger and weaker engagement with the belt in order to set the desired amount of tension in the belt. One or more sensors may be used to sense the amount of tension in the belt, and the one or more sensors may be in communication with a control system that controls the actuator to monitor and adjust the belt tension so that it is maintained within desired limits.

A crusher includes a blade assembly and a drive assembly. The blade assembly includes a first blade and a second blade. The drive assembly is respectively connected with the first blade and the second blade, and is configured to drive the first blade and the second blade to rotate. The first blade is configured to disperse and perform primary cutting of the materials. The second blade is configured to perform secondary cutting of the materials. The first blade makes the materials fully disperse, so that the second blade can fully cut the materials. In addition, the first blade initially cuts the materials, so that the formed fragments can achieve a better fertilization effect.
