摘要：The device provides for intercepting a determined quantity of the abrasivemixture used in cutting granite or hard stones from conduit (2) which introduces themixture to the sawing machine by means of valve (3). The mixture then is collected in adosing hopper (1) where the density and the viscosity are determined. Afterwards themixture is washed with water and is weighed by means of device (11) so that the quantityof the metallic middlings may be determined. Finally, the discharge valve (4) is opened sothat the mixture may be recycled to the conduit (2).
