Description

TECHNICAL FIELD

[0001] The utility model relates to cement fineness detection technical field, specifically is a kind of for the fineness detection device of cement. BACKGROUND

[0002] Fineness refers to the fineness of cement particles. The finer the cement particles, the larger the surface area of reaction with water, so the hydration reaction is faster and more complete, and the early strength is also higher, but the hardening shrinkage in air is larger, and the cost is also higher. If the cement particles are too coarse, it is not conducive to the development of cement activity. Generally, when the cement particles are less than 40 μm (0.04 mm), they have high activity, and when they are greater than 100 μm (0.1 mm), their activity is very small.

[0003] When detecting cement particles, the fineness of the cement particles is generally observed by sieving. When sieving on the surface of the set sieve, the cement particles that meet the specifications automatically fall down, and the particles larger than the sieve aperture remain on the surface of the sieve. If there are too many particles that do not meet the specifications, they will accumulate on the surface of the sieve, affecting the sieving detection effect.
