Construction Mining Machinery – Industrial

In addition to duplex bearings that combine a pair of single row tapered roller bearings, there are also four-row tapered roller bearings composed of two double-row inner rings, one double-row outer ring, and two single-row outer rings. Four-row tapered outer bearings are used in high-load applications such as rolling mill roll necks.

(PDF) Ultimate bearing capacity of footings on coal

The bearing capacity of shallow foundations on ash fill estimated using conventional methods lead to arbitrary estimates because of the absence of the representative parameter for the progressive failure of the ash. This was incorporated by the use of the relative dilatancy index in prediction of ultimate bearing

Pulverizer - Wikipedia

Types of coal pulverizers. Coal pulverizers may be classified by speed, as follows: Low Speed; Medium Speed; High Speed; Low speed Ball and tube mills. A ball mill is a pulverizer that consists of a horizontal rotating cylinder, up to three diameters in length, containing a charge of tumbling or cascading steel balls, pebbles, or rods.

Impact Crusher - an overview ScienceDirect Topics

Impact causes immediate fracture with no residual stresses. This stress-free condition is particularly valuable in stone used for brick-making, building, and roadmaking, in which binding agents (e.g., tar) are subsequently added. Impact crushers, therefore, have a wider use in the quarrying industry than in the metal-mining industry.

Causes, effects and prevention of bearing failures

Often, two identical bearings are used in two identical applications, but because they are located in multiple areas of the same plant, different lubrications are required. Even slight changes in operating conditions can result in bearing and equipment disasters, so the lubricant should be re-examined to determine if a different bearing is required.
