Fines Recovery Fines recovery occurs in almost all forms of minerals and materials processing All plants that wash any kind of material will inevitably end up with some sort of wastewater effluent containing extremely fine material as a byproduct of the washing processAn exposed aggregate surface is obtained by placing concrete and then removing the outer skin of cement paste to uncover decorative coarse aggregate either batched into the concrete mix or seeded onto the surface Because of its durability and skid resistance an exposed aggregate finish is ideal for most flatwork including

Aggregates can be classified in many ways Classification of aggregates based on shape and size such as coarse and fine aggregates are discussed here Aggregates are the important constituents of the concrete which give body to the concrete and also reduce shrinkage Aggregates Based on the practical experience the fineness modulus of fine aggregate should be between 2 to 35 and of coarse aggregate between 35 to 8 Usually the Fineness modulus is calculated for fine aggregate rather than for coarse aggregate Remove the nest of sieves from the shaker and obtain the weight of material retained on each sieve
