Method for measuring granularity of calcium oxide by wet process

The invention discloses a method for measuring granularity of calcium oxide by a wet method. Weighing a calcium oxide sample with the mass of m1 by using an electronic balance; putting the weighed calcium oxide sample into a dry beaker, adding absolute ethyl alcohol, and uniformly stirring to obtain a turbid liquid; selecting a proper standard sieve, cleaning the standard sieve and keeping the weight constant; pouring the obtained turbid liquid into a standard sieve under continuous stirring, washing residues in the beaker with absolute ethyl alcohol, and pouring into the standard sieve; washing oversize products with absolute ethyl alcohol; drying or naturally air-drying the standard sieve with the oversize substances until the weight is constant, and then weighing to obtain the mass m2 of the oversize substances; and calculating the calcium oxide particle size sieve residue percentage according to the masses m1 and m2. By adopting the method for measuring the granularity of calcium oxide by the wet method,
