The biomass pellet machine is our patent product. It is vertical ring die type. It can make biomass pellets from various materials. Its design is mature and reliable. By Wood Pellet Machine, raw material is feeding vertically and directly in place, with stationary die and moving roller, the material is centrifugal and spread evenly around the die. The independent ejection device ensures the forming rate of pellet, the good design lowers the consumption and enhances the efficiency. It can work 24 hours and lubricate automatically. More than 200 wood pellet lines in and abroad have adopted this machine.

Safety valve installation and maintenance and precautions
Safety valve is a kind of safety protection valve, its opening and closing parts are normally closed under the external force. When the medium pressure in the equipment or pipeline rises and exceeds the specified value, it will be automatically turned on. The medium is discharged to the outside of the system Medium pressure in pipe or equipment exceeds specified value. Safety valves are automatic valves, mainly for boilers, pressure vessels and pipes, the control pressure does not exceed the specified value, the personal safety and equipment plays an important protective role. Press the safety valve flap opening height can be divided into micro-Kai-type safety valve and full-valve safety valve, micro-open safety valve opening stroke height: ≤ 0.05d0 (minimum discharge throat caliber); full-Kai safety valve open Height ≤ 0.25d0 (minimum discharge throat caliber). Safety valve according to the structure of the points, should be divided into vertical hammer, lever type, spring type and pilot type (pulse type); According to the valve body structure can be divided into closed and not closed two. Closed safety valve that is not excluded from the media, all along the exit to the designated location, generally used in toxic and corrosive media. For air and steam safety valve, multi-use non-enclosed safety valve. For the selection of safety valve products, the actual sealing pressure should be determined. For spring-loaded safety valves, springs with several working pressure ratings within a nominal pressure (PN) range should be specified when ordering, in addition to indicating the safety valve model, name, medium, and temperature , Otherwise according to the maximum sealing pressure supply. Safety valve installation and maintenance should note the following: All kinds of safety valves should be mounted vertically. Safety valve outlet should be no resistance, to avoid compression phenomenon. Safety valve should be specially tested before installation, and check its official seal. The use of safety valves should be regularly checked.
