Ballast Cleaning machine Clear sieve dirty road bed used machinery, according to the use can be divided into road bed slope cleaning machine and the full section of the Road Bed screen machine, ballast cleaning machine can be divided into three categories:
1. There is no need to blockade the line, the use of the train gap operation of small machinery, such as small-scale road bed slope cleaning machine and small pillow bed clear screen machine;
2. Need to blockade the line to carry out the operation of the rail-type heavy-duty road-bed cleaning machine and the slope cleaning machine;
3. In the demolition of the track after the operation of the screen machine, ballast cleaning machine according to its structure can be divided into vibrating screen and centrifugal sieve type two.
Western Europe, North American railways are more than the use of vibrating screen-type rail cleaning machine; The Soviet Union Railroad uses the centrifugal sieve type orbit to clear the sieve machine; the Soviet Union Railroad also takes the tractor to pull the centrifugal sieve type clear sieve machine, the centrifugal sieve type clear sieve machine's efficiency is high, but the sieve quality is poor, the dust is big, the working conditions is not good.
