Little abrasion wear, Long service life

Based on 30 years of development experience of grinding equipment, LM Heavy Industry produced LUM Series Superfine Vertical Roller Grinding Mill to make ultra-fine powder. The grinding roller doesn't contact with millstone usually, which makes abrasion little and service life longer.

Applications: Superfine dry powder of none-metal ores such as calcite, marble, limestone, coarse whiting, talc, barite and dolomite and so on.

    The Effect of Aggregate Properties on Concrete

    Aggregate is classified as two different types, coarse and fine. Coarse aggregate is usually greater than 4.75 mm (retained on a No. 4 sieve), while fine aggregate is less than 4.75 mm (passing the No. 4 sieve). The compressive aggregate strength is an important factor in the selection of aggregate. When determining the get price

    Effects of binder strength and aggregate size on the compressive

    To test the influence of binder strength, porous concretes with 4 binder strengths between 30.0–135.0 MPa and 5 void ratios between 15%–35% were tested. The results indied that for the same aggregate, the rates of strength reduction due to the increases in void ratio were the same for binders with different strengths.get price
