In the case of process of mining of mineral resources as disintegration of variety of materials is always crucial to choose optimal technology to prevent wastes in energy, human resources and also financial resources. It is also essential to avoid negative impacts on the nature and prevent serious damages in environment in general. This article is focusing mainly on the various ways of mechanical disintegration of materials without usage of blasting in the mining condition (surface mines, coal mines, tunnel boring...

This article deals with the forming of sheet metal on a bending machine. The bending of sheet metal cut shapes or clippings is a very common operation in many companies. Oftentimes, many of these companies deal with the issue of how to bend the sheet metal to the required precision, especially while complying with the required bending angle. The sheet metal is bent correctly while it is in between the tools of the machine. However, stress develops in the material during bending and this stress remains in the mater...

Nowadays, when the whole world is increasingly engaged in environmental protection, it is necessary to come up with a fuel alternative for transport, which means generally abandoning the use of non-renewable resources (fossil fuels), as they are one of the many factors influencing the emergence of greenhouse gases and its associated global warming. In today's Europe, pressure is being put mainly on automotive companies, to search for sources other than conventional fuels. At present, there is a big boom in the are...

Recycling of spoil and demolition wastes is in general complicated process, that require quality processing technology connected with equipment designed for those purposes. During recycling is important factor perfect separation of spoil and demolition waste. Mainly separation of individual components of such waste as glass, plastics, metal parts, wood etc. From concrete, bricks, asphalt and similar construction material. Separated components are utilized by their type. It is necessary to not have dangerous admixt...

During the process of conceptual designing of earthmoving or construction boom type machine we have must ensure that it is applicable in practice, meaning stable. Unfortunately, not every time is design of upper structure of such a machine ideal in consideration of position of centre of gravity and that is the reason why are stabilizing outriggers usually attached. This article talks about possibilities of use various schematic drafts of stabilizing outriggers for earthmoving and construction machines on the wheel...
