Mechanics of crushing media in ball tube mills with transverse-longitudinal motion of grinding bodies
The paper considers the method of calculation of kinematic parameters of the transverse-longitudinal motion of grinding bodies in a ball tube mill. The mathematical dependences allowing to calculate the angles of ball bounce from the inner surface of the mill tube and t...| Author: V.S. Bogdanov, S.I. Antsiferov, D.V. Bogdanov, Ye.A. Sychev |

Structural and heat insulating foam concrete made with drill cuttings
The article presents the results of drill cuttings effect upon the properties of cement foam concrete mix and naturally cured foam concrete. Drilling cuttings (a by-product of oil extraction) are suggested to be used as a fine aggregate for constructive and heat...| Author: A.B. Steshenko, A.I. Kudyakov, N.O. Kopanitsa |
