The aggregate raw materials in the concrete block machine equipment are mainly used as inert fillers, reducing the cost of raw material grinding and processing, and also improving the strength and durability of the product. However, when the ratio is large, the water absorption rate of the cement brick machine block will increase.
Firstly, the fine material can slow down the sedimentation and separation speed of the material, and create good conditions for the stability of the slurry that is being stirred evenly or just after the gas is released, so that the slurry has good water retention; secondly, the slurry has proper The consistency and fluidity create good conditions for initiation of swelling.
How to mix the coarse and fine materials? At present, most sieve analysis methods are used to determine the degree of thickness and particle grading: a set of standard-accuracy square-hole sieves with apertures of 4.75mm, 2.36mm, 1.18mm, 0.6mm, 0.3mm, and 0.15mm are used in order of the size of the sieve , 500g of dry sand sieved with a 9.5mm square hole sieve is sieved from coarse to fine, and the sieve amount on each sieve is weighed.
The above is the answer of how to mix the coarse and fine materials of the cement brick machine. I hope it will be helpful to everyone.
