The paper deals with the problem of stabilization of traction wheels engagement with the traction rail in a lever-type mechanisms. The stabilization systems used in suggested designs of traction devices make available to obtain the constancy of the transfer ration of the lever system, which is independent of both drive wheels and traction rail wear. Thus, the constancy of the engagement coefficient is possible to obtain without usage of any additional regulating device.
Traditionally, it is customary to determine the capacity of a jaw crusher based on the volume of the so-called dropout prism in the limiting zone. In case of straight jaw outlines, this zone is located at the very bottom of the working space. It is assumed that the material is discharged only when the movable jaw is moving away. As the jaws move closer together, the material is crushed and no discharge takes place.
The advantage of briquetting over such pelletizing and sintering processes is that briquetting allows to obtain a product of strictly regulated dimensions, and no chemical transformations take place in the initial mixture during the briquetting process. In addition, this process is the most favorable from the point of view of sanitary requirements.
Due to the involvement of poorer ores in production, the capacity and share of beneficiation equipment in the industry is constantly increasing, and issues of its safety are becoming increasingly important.
Основная цель расчета - определение мощности, потребляемой приводом во время работы машины. Расчет входит составной частью в комплекс расчетов, выполняемых при проектировании флотационной машины, причем выполняется он в первую очередь ...
In the literature on flotation theory, much attention has been paid to mathematical modelling of the kinetics of the flotation process ...
The influence of some basic factors on the process of wheel-rail adhesion can be evaluated using a bar model. Such a model has been applied when considering the contact between two flat surfaces. ...
One of the most important aerohydrodynamic indicators of any flotation machine is aeration. With the concept of aeration identify quantitative ratios of air and liquid phases, as well as qualitative characteristics of the size of air bubbles and their distribution over the volume of the chamber. The quantitative side of the aeration process can be expressed through the degree of aeration and the density of the flotation system. ...
One of the characteristic features of the flow in the chamber of a mechanical flotation machine is its inhomogeneity. Air bubbles of varying size pass through any point in the chamber, capable of increasing in size as they float and coalesce. The inhomogeneity is particularly strong in the lower layers of the chamber, where the turbulent nature of the motion prevails. ...
