A coal which caused excessive wear in commercial grinding in a pindisc mill gave an extremely high ''abrasive index'' when subjected to this laboratory test. Abrasive indices have been determined for a series of New Zealand coals.
coal [1].To study the abrasion of coals, an index namely abrasion index (AI) which has been used to assess the abrasive nature of the thermal coal was established first by Yancey, Geer and Price (YGP) in 1951 using YGP test rig. Over the years there have been some modifications to this method by both mining houses and coal users which have
Jun 05, 2013· Abrasion index is an index that shows the abrasive properties (abrasion) of coal on the part of the equipment used to grind the coal before being used as fuel in certain combustion systems. The higher the index the abrasive coal the higher the maintenance costs of the coal grinding equipment.

Coal sampling and analysis standards 4 Abstract Each year, billions of tonnes of coal are traded in regional and international market for use in power generation, steel and cement making, and many other purposes. In commercial operations, the price of coal not only
A 60 mm coal pencil, formed under pressure from minus 60 mesh coal, is inserted into a precisely calibrated retort tube with a graduated piston on top. The sample is then placed in a furnace. The apparatus is heated at 3°C/minute and the movement of the piston, as the coal pencil shrinks and expands, is recorded. The maximum dilatation value ...
area cleaned, blasting time, and the abrasive consumed, environmental performance of coal slag and garnet was evaluated. Simple mathematical models were developed to predict performance based on feed rate and blast pressure. Garnet was observed to be more productive, less consuming, and more environmentallyfriendly compared to coal slag.

Assessment and prediction of coal abrasiveness Chris Spero Queensland Electricity Commission. Box 10, Brisbane. 4001. Australia (Received 25 April 1990) The abrasive properties of coal were measured in terms of the content, composition and physical properties of the coal mineral matter, and the grindability and bulk density of the coal.
Abrasion testing. Abrasion is the property of the coal which describes its propensity and ability to wear away machinery and undergo autonomous grinding. While carbonaceous matter in coal is relatively soft, quartz and other mineral constituents in coal are quite abrasive. This is tested in a calibrated mill, containing four blades of known mass.

smallscale coal mill, which operates at a raw coal throughput of 5 kg h1, and which permits direct measurement of the weight losses of the coal grinding elements due to abrasive wear. The Minimill product was then employed as the feed material for the Erosion Rig experiments, and to provide samples of pulverised coal for the CCSEM work.
