Physical processes, arising up at removing of rock from the backwall of mining hole, are considered. The curve of sedimentation, allowing to determine the rate of climb of transporting of rock at cleaning of back-wall with newtonian liquids – air and water, is shown. The formula is shown out for the calculation of ex-pense of borax solution, necessary for the high-quality cleaning of backwall of mining hole at washing water or air
This article deals with the rules of observance of agriculture technology requirements for the production of potatoes in particular. On the example of the combine PDA 1.2, we have considered the places having the greatest damaging effect on roots. One can also find a summary procedure for calculating the probability of defective products
The article deals with key issues relating to energy efficiency in Russia, as well as the main directions of energy saving in agriculture
In this article, the dynamic characteristics of a hydraulic actuator of a wood soil-cultivating mill as object of automatic control are presented
The model of identification of process of a dust con-tent of the air is submitted. It is shown, that in a work-ing zone of foundry shops the significant amount of a dust is allocated. The most unsuccessful sites from a position of allocation of a dust are chambers and lattices. The experimental analysis shows, that in structure of a dust the weight maintenance of fractions with a diameter up to 20 microns reaches 43,8 % on weight. The dust is most dangerous to health of the working personnel and creates problems at clearing air. The model of structure of dusty air is received
In the article, wear resistance of an antifrictional poli-merno-metal material in direct and return steams of a friction, taking into account the conditions and modes of operation of bearings of sliding in timber equipment is considered
Methods of jet pneumoautomatics with reference to devices of moving on an air pillow are considered. The local system constructed on the basis of methods of jet pneumoautomatics, for management of thickness of an air pillow is shown. In clause the opportunity of automatic removal of dusty air from a working zone of pneumotransport system is reflected. On the basis of hydro dynamical calculation parities for engineering calculations of values of
In the given article, the role of application of auto-mated systems, and also computer facilities is consi-dered in detail at designing and production process of the enterprises of a wood complex. The theoretical substantiation of structure and structure of the information system, providing the decision of problems of the timber industry enterprise is resulted.
Processes of heat-mass exchange the thermo chemical processed wood, as object for modeling technology of convectional dryings of difficultly drying breeds of wood are considered
The article presents the results of the research of the density of wood, affected by various types of fire. The analysis of structural changes in the wood, based on its micro and macro structure is given
