sand vs clay vs crusher dust

 · Depending on the crushing equipment and the type of rock, you could end up with a lot of flat fines that distort the gradation and compact differently. That will not compact weel and can shift later. Also, if the rock is limestone, the fines can be cubic and there is an amount of cementing ability in the fine fines that can develop later.

Clean v. Minus: Your Questions Answered | Washington Rock ...

 · Clean rock products contain no fines (small particles of ground rock). Minus rock does contain fines. Fines help a product compact. For example, if you''re building a driveway over soft ground, a minus product can compact and stay in place. Watch the video to see the difference between crushed clean and crushed minus rock products.

Aggregates for Concrete

Crushed stone is produced by crushing quarry rock, boul-ders, cobbles, or large-size gravel. Crushed air-cooled blast-furnace slag is also used as fine or coarse aggregate. The aggregates are usually washed and graded at the pit or plant. Some variation in the type, quality, cleanli-ness, grading, moisture content, and other properties is expected.

Cone Crushers | McLanahan

A Cone Crusher will deliver a 4:1 to 6:1 reduction ratio. As we set the closed side setting tighter to create a finer output, we also reduce the volume or throughput capacity of the machine. Generally speaking, multiplying the closed side setting by two is a good guide to the top size of the gradation …

Sieve analysis

A sieve analysis (or gradation test) is a practice or procedure used in civil engineering and chemical engineering to assess the particle size distribution (also called gradation) of a granular material by allowing the material to pass through a series of sieves of progressively smaller mesh size and weighing the amount of material that is stopped by each sieve as a fraction of the whole mass.

5 Aggregate Production

Scalping (Figure 5-6) most often is used to divert fines at a jaw primary crusher in order to improve crusher efficiency. In this way the very coarse portion is crushed and then recombined with the portion of crusher-run material before further processing. This first step may, however, be an excellent time to improve a deleterious problem.
