The load of the wood shredder affects the grain size and energy consumption of shredded products, and also affects the normal operation of the wood shredder. Under the same working conditions, the shredded sorghum is twice as powerful as shredded corn stalk and the shredder is tested. The load is a major cause of its failure analysis.
Due to the high speed of the wood shredder and the large load, the fluctuation of the load is greater due to different types of wood. Therefore, when different screens are used, the load on the shredder has a great influence. When using a sieve with a sieve diameter of 1.2 mm, the motor capacity should be 40 kW; when using a sieve with a sieve diameter of 2 mm, the motor capacity should be 30 kW; when using a sieve with a sieve diameter of 3 mm, the motor The capacity should be 22 kilowatts, otherwise it will cause some waste. The method for overloading the wood shredder has its own set of methods to detect: 1 Directly use the contact level gauge to indicate the level of material in the comminution chamber, ie to know the load. 2 Weigh the delivery volume of the wood belt shredder feeder belt conveyor with a belt scale. 3 Calculated by crushing and screening the closed loop system's cyclic load. 4 The current value in the motor circuit of the wood crusher is measured, and the current during operation of the crusher is generally controlled at about 85% of the rated current. 5 In the multi-stage comminution, generally only the last stage of the crusher is controlled to control the particle size of the final product. This crusher is usually in a closed circuit system, and the feed amount includes the amount from the previous crushing stage and the cyclic load.
