APPARATUS FOR CONDITION CHECKING OF SCREEN CLOTH IN A VIBRATING SCREEN FOR DRILLING FLUID AND METHOD

摘要

An apparatus (1) is described for the condition checking of a screen cloth in a vibrating screen for drilling fluid, comprising a pump (2) for drawing a drilling fluid sample from the bottom tray of the vibrating screen into the apparatus (1); a filter (3) for filtering the drilling fluid sample; and a pressure gauge (4) for measuring the pres sure difference across the filter (3). A method is also described for the condition checking of a screen cloth in a vibrating screen, comprising drawing a drilling fluid sample from the bottom tray of the vibrating screen; filtering the drilling fluid sample through a filter (3); and measuring the pressure difference across the filter (3).
