crushing. These factors include (1) stone type, (2) feed size and distribution, (3) moisture content, (4) throughput rate, (5) crusher type, (6) size reduction ratio, and (7) fines content. Insufficient data are available to present a matrix of rock crushing emission factors detailing the …

The difference between a conventional impactor and a VSI of the Barmac type is that the latter offers lower operating costs, but its reduction ratio is lower also. In a Barmac VSI, the material undergoes an intense rock-on-rock crushing process. In the other crushers, most of the reduction is done by the impact of stone against metal.

High reduction ratios of between 20:1 and 40:1 can be achieved with hammer type impact crushers. Only low reduction ratios of about 2:1 can be achieved with kinetic energy type impact crushers. 5.1.3 Crushing mechanisms and product size distributions. The crushing action of a crushing machine is described most usefully through the classification -

Impact crushers (rotary or hammer mills) have the capacity for high reduction ratios (up to 40:1), but are rarely applied to hard rock mines. Since they depend on high velocities for crushing, wear is greater than for jaw or gyratory crushers.

All crushers have a limited reduction ratio m eaning that size reduction will take ... 5.0 Types of Crushers: ... The HSI crushers break rock by im pacting the rock with hammers that are fixed ...

As an example, suppose that it is required to make a reduction of 7:1 in two stages of crushers, one a standard gyratory and the other a fine-reduction crusher. We know from our examination of the crushing characteristics of these types that, for equal reduction ratios, the volume-reduction-ratio in the standard gyratory is considerably higher ...

Compression-style jaw, cone, impact crushers, and gyratory crushers are most often appropriate as primary crushing equipment types, though there can be overlap between primary and secondary crushers as far as suitable types. 2. Secondary Crushing. In secondary crushing, reduction ratios …

Jaw crushers offer reduction ratios of up to about 6:1, while cone crushers can reduce material size up to a maximum of 8:1 ratio. The finer the crushing, the smaller the reduction ratio. As a basic rule, jaw crushers are the primary crusher taking the mined aggregate and reducing it to a size that a cone crusher can accept.
