VSI sand maker, also called VSI crusher, is the major machine for sand making plant.
Ball mill is the key machine to grind the crushed materials. Ball mill machine is widely used to process cement, silicate product, building material, refractory material, fertilizer, ceramics and glass, etc.
On the basis of domestic mills, fote raymond mill is produced. The raymond roller mill enjoys the features of high working efficiency, low energy consumption, small floor space and small cost.
Nov 13, 2020 in coal-based dri process, accretion formation inside the rotary kiln is a genuine complex problem. accretion formation in a rotary kiln of 100 tpd dri plant has been investigated. the nature of accretion formation with respect to the charge burden and operational parameter have been discussed. high ash content in the coal and excess use of dolomite lead to accretion formation.

Iron ore sponge iron rotary kiln . mar 01 2017nbsp018332the geometry of rotary kiln of sponge iron process is developed using gambit 246 dimensions of kiln are 80 m length and 4 m internal diameter the kiln is inclined to 25 degree to the horizontal and rotated with 43 rpm bed material consists of iron ore coal and dolomite enters the kiln through feed end.
Computational fluid dynamics analysis of sponge iron. all walls of the kiln burner and air inlet are developed using no slip walls method 28 raw material which is a mixture of iron ore coal and dolomite is entered from the feed end at 27 c the product ie sponge iron is collected from discharge end at 950 c flue gases are released from feed end at 900 c
Iron ore and non-coking coal are the prime raw materials for the production of sponge iron. these are charged into a rotary kiln in requisite proportion along with some dolomite. coal plays a dual role in the process by acting as a reductant as well as a fuel for providing heat to maintain the requisite temperature inside the kiln at 950-1050 o c.
