Problems And Solutions Encountered In The Use Of Log Splitter

  1. The sieve holes of the log splitter bottom screen or the air inlet of the pipe are partially blocked, resulting in the insufficient air intake.

  2. The fan blades are worn or the impeller speed is too low.

  3. If the wood chips are too large, the air buoyancy generated by the fan is not enough to overcome the weight of the wood chips. Large pieces of wood tend to get caught in the duct elbows.

  4. The raw material is too wet, and the debris in the wood chips is easy to adhere to and accumulate on the inner wall of the air duct, especially the elbow. Especially in winter, the accumulated material freezes, causing the air duct to block.

  5. The radius of curvature of the elbow of the wood chip conveying pipe is too small.


  1) Control the moisture content of the original material to ensure that the moisture content is 30-50%. The soaked raw materials should be dried with surface water before slicing.

  2) To transform the chipping process, the short section below 30 cm should not be used to prevent the generation of large wood chips and jam the fan blades or air duct elbows.

  3) The radius of curvature of the duct elbow should be greater than or equal to three times the diameter of the duct, R>3D.

  4) Pay attention to check whether there are foreign objects blocked in the sieve hole of the bottom sieve and the air inlet door.

  5) If the air intake volume is normal, and the air supply pipe is not blocked, but the material cannot be fed, check whether the fan impeller is worn and whether the fan speed is normal.

  6) In the production of log splitter, when there is no clear and fluent rustling sound of wood chips hitting the pipe wall in the air supply pipe, or when fine pieces of wood are found to come out, it can be judged that the air duct is blocked and the air duct should be checked in time. , at the outlet of the fan and cyclone separator. Generally, the blockage of the air duct mostly occurs at the elbow, and sometimes the discharge port of the cyclone separator is blocked due to the poor lower section of the vibrating screen.
