Technological Process. Dry the wet slag first, and then feed it into the main grinding room for grinding. The fine powder after grinding is classified by the analyzer under the action of the air flow of the fan, and the qualified fine powder enters the collecting stage. The fine powder with qualified fineness enters the pulse dust collector.

Grinding. The first step of the grinding process requires the slag to be dried down to about 2.5% moisture. These dried granules are then pre-ground with two high pressure roll presses. These machines consist of two large rolls, forced together by high pressure hydraulics. The granules are fed between the rolls and crushed.

slag grinding offers a further benefit as the mill not only grinds the material but also dries it in the process. The normally-moist slag, with an eight per cent water content, is dried and ground in one step while the water helps to stabilise the mill operation during grinding. This also lowers vibration and specific power consumption on the

In cement industry, many grinding up systems are on operating now. The tradition process of tube mill grinding system is high energy consumption, so it’s low efficiency, especially in the final cement grinding process. The value and advantage of slag is recognized more and more, but it’s difficult to be grinded up. Furthermore, the disadvantage and shortages to grind up clinker compounded ...

While most grinding in the mineral industry is achieved using devices containing a steel grinding medium, the IsaMill uses inert grinding media such as silica sand, waste smelter slag or ceramic balls. The use of steel grinding media can cause problems in the subsequent flotation processes that are used to separate the various minerals in an ore, because the iron from the grinding medium can ...
