You have not mentioned circuit of your mill.I 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 mill.The other way is to decrese cut size of your dynamic separator by increasing cage rotor speed.

CEMENT PLANT TALK-001

Cement Mill Common Issue:Higher cement temperature, Mill tripping under high cement temperature or mill outlet temperature is not an uncommon in cement mills. It happens in majority of cases due to high clinker temperature and the other reasons could be insufficient mill venting and insufficient or faulty water spray system.

cement blaine and residue on 45 micron control? Page 1 of 1

Apr 07, 2013· can you please share your opinion about the what are the main levers to control the blaine and residue on 45 micron in cement product indivisually. take any case -1,our blaine is 3400 cm2/gm and residue on 45 micron is 13% and if we want to reduce the residue by 3% with out affecting the blaine, how it is posible? (or vise versa). thanks. regards

Effect of insoluble residue on properties of Portland cement

Aug 01, 2000· 1. Introduction. Insoluble residue is a measure of adulteration of cement, largely coming from impurities in gypsum and can be found by treating the cement with hydrochloric acid and sodium hydroxide .ASTM C 150 limits the insoluble residue in Portland cement type I not higher than 0.75%. BS 12: 1996 sets the limit for insoluble residue at 1.5% for cement not containing a minor additional

If the bypass is 40%, and if the production is 100 t/h, then, naïvely speaking, this means that 40 t/h of good product is returned to the mill. This could be, naïvely, translated as an efficiency of 100/140 = 70% and would indicate that the production could be increased by

Oct 23, 2015· Better product quality can be achieved as compared to the ball mill product due to the better options for separate grinding. For example, in additive cement production, the blast furnace slag has to be ground to Blaine values of 5,000 cm 2 /g. Water demand and setting times are similar to that of a ball mill cement under comparable conditions .

product the cement. The fineness of cement is usually monitored by measuring the specific surface area (Blaine) or a sieve residue of the product. However, the effects of the mill system on the quality of the product are more complex than what is reflected by a Blaine value or a sieve residue. It includes the following factors associated
