WEAR RATE PREDICTION OF GRINDING MEDIA USING BPNN AND MLR MODELS IN GRINDING OF SULPHIDE ORES
Nowadays steel balls wear is a major problem in mineral processing industries and forms a significant part of the grinding cost. Different factors are effective on balls wear. It is needed to find models which are capable to estimate wear rate from these factors. In this paper a back propagation neural network (BPNN) and multiple linear regression (MLR) method have been used to predict wear rat...
متن کاملDuPont Pigment Dispersion in Liquids
Initial Wetting It is virtually impossible to disperse a material in a liquid that will not wet the surface of the material, e.g., aluminum stearate in water. However, most commercial pigments are fairly well wet by the vehicles used and differ appreciably only in their rates of wetting. This is usually evident in the latter stages of making a heavy paste; because, at this stage of mixing, ther...
متن کاملSurgical Management of Iatrogenic Pigment Dispersion Glaucoma.
INTRODUCTION Iatrogenic pigment dispersion syndrome generally originates from a repetitive, mechanical trauma to the pigmented posterior epithelium of the iris. This trauma can arise after intraocular surgery, most commonly due to an abnormal contact between the intraocular lens (IOL) and the iris. Whether surgical removal of this primary insult can lead to a successful intraocular pressure (IO...
متن کاملRetinal pigment epithelial dysfunction in patients with pigment dispersion syndrome: implications for the theory of pathogenesis.
OBJECTIVE To test the hypothesis that the retinal pigment epithelial/photoreceptor complex is affected in patients with pigment dispersion syndrome and/or in patients with pigmentary glaucoma. METHODS Electro-oculograms were recorded from patients with pigment dispersion syndrome, pigmentary glaucoma, ocular hypertension, and primary open-angle glaucoma and from control subjects. Electro-ocul...
متن کاملGrinding-aid effect on the colour properties (Ry, whiteness and yellowness) of calcite in stirred media milling
This study investigates the influence of some chemical additives such as methanol, ethanol, sodium oleat, chloroform and sodium hexametaphosphate (SHMP) on the dry fine grinding of calcite (X50= 33 µm) using a stirred media mill. The experiments were carried out by a batch operation, and the change in colour properties (Ry, whiteness and yellowness) of calcite powder. The results showed that th...
