The Crusher throw is defined as the distance in the direction of compression the moving crushing surfaces/plates travel from OSS to CSS. Throw = OSS – CSS. OSS and CSS will define a crusher’s performance. The throw of the crusher is the distance that moving jaw moves in going from OSS to CSS. The capacity is a function of size and OSS.

Crusher Dust is a a finely graded crushed blue stone similar to Roadbase. It can be compacted firm and used as a sub-base for a variety of applications. Under pavers we recommend you use Roadbase due to its superior drainage and lower mineral content (high mineral content and moisture content can casue Efflorescence to appear). 1.6 Tonne = 1m 3.

With a mechanical filter, filter efficiency and the pressure drop across the filter increases as the filter begins to load. The increase in pressure drop will decrease airflow, which will eventually result in unacceptable air quality, and potentially cause leaks, leading to a decrease in the efficiency of the system to reduce respirable dust.

Quarried stone normally is delivered to the processing plant by truck and is dumped into a bin. A feeder is used as illustrated in Figure 11.19.2-1. The feeder or screens separate large boulders from finer rocks that do not require primary crushing, thus reducing the load to the primary crusher.
