Crushed stone #1 is the largest of the crushed stone grades and includes stone that is between 2-4 inches. This materials is great for larger jobs or for filling in larger holes. #3. Crushed stone #3 includes stone between 1/2 and 2 inches. This material is a great choice for railroad projects and those that require drainage.

Description: A starved crusher is an inefficient crusher. If there is not enough material in the crusher to fill it, then productivity and reliability are compromised. Underfilling a crusher will cause increased liner wear and coarser product gradation – it also has a negative impact on the crusher product quality for the quarry industry

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 exiting the machine.

Gradation is the size distribution of a particular riprap or aggregate. Material that is well graded has a uniform distribution of sizes, within a given minimum and maximum range. Void spaces between the larger rock are filled with the smaller material. Void space is reduced which results in a denser placement of riprap or aggregate that is less

Jaw Crushers are sized by the top opening of the crushing chamber. For example, a 32 x 54 Jaw Crusher measures 32" from jaw die to jaw die at the top opening or gape opening and 54” across the width of the two jaw dies. The narrower bottom opening of the crushing chamber is used to size the discharge material.

The gyratory crusher shown in Figure 2.6 employs a crushing head, in the form of a truncated cone, mounted on a shaft, the upper end of which is held in a flexible bearing, whilst the lower end is driven eccentrically so as to describe a circle. The crushing action takes place round the whole of the cone and, since the maximum movement is at the bottom, the characteristics of the machine are

Tables 1 through 5 have gradation guidelines for D50s of 4 inches through 12 inches. The smaller (i.e., 1 and 2 inch) diameters shown should be considered as “weight of material” rather than “number of rock.” The tables can be used to produce gradation sample piles showing the upper and lower limits of the desired gradation.

Jaw crusher output gradation is controlled by the closed side setting. This is the adjustable opening at the bottom of the jaw. With a 24” top size limit and an 8:1 reduction ration, the closed side setting should be no smaller than 3”. A well designed jaw should be 80 to 85 percent efficient. This means that 80 to 85 tons out of every 100
