• ## Negative Pressure Calculation In Vertical Mill

If the soil is able to withstand the negative active earth pressure, the negative pressure over the depth h tc is balanced by a positive pressure over the same depth below Hence, the resultant active earth pressure is zero over the depth H c = 2h tc, known as critical height Thus, excavations in cohesive soils can stand with vertical sidesVertical Negative Pressure Round Sieve Flour Mill Vertical negative pressure round sieve Brief Introduction Vertical negative pressure round sieve is flour extracting machine used in the small flour milling plants The equipment has advantages of low price, good running performance, high efficiency, low power consumption and easy maintenancenegative pressure calculation in vertical mill
