Successful tests of a new heavy throw-screen GIST 92 of enlarged typical size
LLC “Concentrating equipment” which is a part of RUDGORMASH Group performed tests on September 7, 2017 of a new heavy throw-screen, which is planned to be supplied to one of the Siberian coal factories.
The outstanding features of this machine are:
- enlarged screen (width 3600 mm);
- enlarged flexible connection elements that are used for stable operation of wide screens.
Unbalanced throw-screen GIST 92 is designed for size segregation of bulk materials with load volume up to 1,6 t/m3 at the screen slope angle 0-25 degrees during operations of dehydration, desliming, wet and dry (with materials surface humidity not more than 5%) hard coal, antracites and slate coals screening and also separation of the pulp from the washed product.
Connection beam diameter – 219 mm.
Screening surface size, mm – 6900 х 3600
Number of screening layers – 2
Vibration amplitude, mm – 3,0 – 5,0
Nominal motor rating, KW – 2 х 45
Size of feeding particles, mm, not more than – 300
Mass of moving part (without screening surface), kg – 20000
Distance between supporting beams and lower layer screens support – 500 mm.
The recommended amplitude at vibration frequency 970 rpm – not more than 4 mm.
