Comminution by gyratory crusher is the first stage in size reduction operation mineral processing. In copper industry, these machines are widely utilized, and their reliability has become a relevant aspect. To optimize design to improve availability of crushers, it necessary calculate power torque accurately. The discrete element method (DEM) been commonly used several mining applications power...

in this paper, we investigate the continuity of linear and sublinear correspondences defined on cones in normed spaces. we also generalize some known results for sublinear correspondences.

In the comprehensive development and utilization of crop straw, it is key to separate fibers in straw through a certain process or equipment. order obtain rice fiber material, crusher was designed using SOLIDWORKS software, its grinding simulated EDEM software verify feasibility machine principle structural rationality. The wheel speed, screw feed shaft clearance were used as test factors desig...

China is a large agricultural country, each year will produce number of straw. The recycling straw to China's development and environmental protection are very helpful, the mainly energy, fertilizer, feed several uses, different uses need crushing fineness, so adjust fineness can improve rate This paper on impact factors for focuses theoretical analysis study affecting crushing, provides genera...

In this paper, using Clarke’s generalized directional derivative and dI-invexity we introduce new concepts of nonsmooth K-α-dI-invex and generalized type I univex functions over cones for a nonsmooth vector optimization problem with cone constraints. We obtain some sufficient optimality conditions and Mond-Weir type duality results under the foresaid generalized invexity and type I cone-univexi...

In this paper, we prove some properties of algebraic cone metric spaces and introduce the notion of algebraic distance in an algebraic cone metric space. As an application, we obtain some famous fixed point results in the framework of this algebraic distance.

Recently, Choudhury and Metiya [Fixed points of weak contractions in cone metric spaces, Nonlinear Analysis 72 (2010) 1589-1593] proved some fixed point theorems for weak contractions in cone metric spaces. Weak contractions are generalizations of the Banach's contraction mapping, which have been studied by several authors. In this paper, we introduce the notion of $f$-weak contractions and als...
