All or part of the flow can be separated from the discharge pipe of the biomass grinder and directed to the suction inlet of the grinder or other suitable points using a bypass valve. One or several flow orifice plates and Suitable regulating valve. Metering bypass is generally used to reduce the flow of boiler feed water pulverizer, mainly to avoid overtemperature. If the excess flow of bypass propeller pulverizer is used to replace the outlet throttling, a lot of power can be saved. .Clear the amount of fuel added to the biomass grinder based on specific needs, and use calculations and statistics on various types and specifications of biomass grinders to draw the conclusion: the amount of refrigeration oil reaches 1\/1 of the diameter of the drum, and the oil is 3 The oil level is suitable, and this amount of oil can basically meet the refrigeration of the motor of the biomass comprehensive crusher.
Generally, the size of the motor immersed in oil is 1\/4-1\/5, and the lower edge of the transmission can be immersed in oil, and after the drum rotates, it can meet the requirements of refrigeration and lubrication. For medium and low-volume biomass grinders, This is a common and cheap total flow adjustment method. Generally, this method is used in medium and low crushers. Partially closing any valve on the outlet pipe will increase the system pressure head, so the system pressure head curve will be at a lower flow rate. Intersects with the pressure head curve of the biomass grinder. The outlet throttling will move the working point to a lower efficiency point, and power will be lost at the throttle.
This may be important for large crusher installations, and a higher investment adjustment method may be more economically attractive. Throttling to dead center may cause the liquid in the crusher to overheat. You can use a bypass to maintain the necessary small Flow, or use other adjustment methods. This is very important for the pulverizer mentioned earlier for hot water or volatile liquids.
It mainly uses impact energy to carry out wood crushing operations. When the hammer crusher works, the motor drives the rotor to run at high speed, and the wood enters the cavity of the crusher evenly. The high-speed operating hammer impacts, cuts and tears the wood, causing When the wood is broken, the wood's own gravity causes the wood to reach the baffle and screen plate in the frame from the high-speed rotating hammer. There is a screen plate under the rotor, and the broken wood particles smaller than the screen size are discharged through the screen plate, and the wood particles exceeding the screen size are discharged through the screen plate The wood is preserved. Continue to use the hammer to beat and grind the wood board. The function is more powerful, stable, economical, the material has a wide application range, outstanding functions, convenient operation and maintenance, and high crushing output. It is the material of most biomass power plants.
