In the cement grinding and mining industry, product fineness prediction has been subject to various industrial applications. ... For this reason, the output parameter to predict in our soft sensing study will be raw mill fineness at 90 μm mesh sieve residue. Download : Download highres image ... Another study shows that mill outlet ...
The raw materials are dried with waste process gases taken from the kiln system. The target grind is the bulk of the product is less than 75 μm. The mill product or "kiln feed" is pneumatically blended to ensure that the chemical composition of the kiln feed is well homogenized, and then stored in silos until required.
A cement mill (or finish mill in North American usage) is the equipment used to grind the hard, ... so ball mills operate most efficiently by making a coarse product, the fine fractions of this then being separated, and the coarse part being returned to the mill inlet. The proportion of the millexit material returned to the inlet may vary from ...

Cement mill Residue. Sir, We have a ball mill for cement grinding. The residue on 45 mic is 15 to 16 % for blains value of 3400 cm²/grms, any idea how to reduce the residue to around 10 %. jatinder... Reply. Know the answer to this question?

1. Introduction. In the cement industry, grinding is one of the most consuming energy stages in the production units. Around 65% of the total used electrical energy in a cement plant has to be utilized to grind raw materials, coal, and clinker [1,2].Through the process, many variables can affect the efficiency and productivity of this dry grinding procedure, such as the operating conditions of ...
However, the handling and processing of abrasive bulk materials causes significant wear to the roller mill components, leading to their eventual need for replacement or repair. Wear and abrasion can be found in the material feeding section, mill housing, grinding elements, integrated separating system and product outlet areas of the mills.
in combination with a ball mill for cement grinding applications and as finished product grinding units, as well as raw ingredient grinding equipment in mineral applications. This paper will focus on the ball mill grinding process, its tools and optimisation possibilities (see Figure 1). The ball mill comminution process has a high electrical
Additionally, the Portland cement mill technological process (its component parts), as well as the solutions regarding the reduction of the air emissions level, following the emission limit values (VLE), established in the integrated environmental authorization (AIM) from a cement factory in Romania, were analyzed.
By considering the drawbacks, the EP system was replaced by a bag filter (BF) system. The BF allows higher temperature of gas inlet and it has higher dust removal efficiency. In this study, the ...

As a rule of thumb, the residue on 90micron sieve should not be less than half of the volatile content for safety purpose. ie. R90>=1/2. Volatile Content %. Coal Moisture: The degree of drying, and therefore the required mill outlet temperature (from 6580 0 C) will depend upon the type of coal ground.
The air flow throu gh mill is necessary for several reasons. First of all the air tran sports the material inside of the mill and the product out of the mill to the bag filter. But the air also transport s the heat for the drying process .Furtherrn ore the air fluidizes and stabilizes the grin ding bed.

Re: Cement mill Residue. Dear Mr Jatin, You have not mentioned circuit of your assume that it might be a closed circuit cement mill. Best possible way to reduce residue on 45micron is by increasing circulation factor across the other way is to decrese cut size of your dynamic separator by increasing cage rotor speed.

Abstract: The utilisation of coal in the cement and concrete industries takes three basic forms: 1. As a fuel in the production of cement clinker, 2. Ash produced by burning coal in power stations is used as a component in cement rotary kiln feeds, 3. Ash produced by burning coal in power stations is used as a mineral additive in concrete mixes.
The outlet temperature of the coal mill is maintained at desired point so that the coal delivered from the mill is completely dry and achieves the desired temperature. Also, in case of high temperature at the mill outlet, cold air is blown in to reduce the risk of fire. Discussion

Strategy to fix the issue: Proper mapping of your mines, regular and frequent analysis of extracted material will fix the issue. Plot a time chart of various components (TC or CaO, SiO2, Al2O3, Fe2O3) while making stock piles for feeding in raw mill, monitor sigma capability of process continuously.
Optimum performance of ball mill could potentially refine Blaine fineness, thereby improving the cement quality. This study investigates the effects of separator speed and mill speed on Blaine ...
