Jaw Crushers. Jaw crushers are the most commonly used crushed stone machines. They have a simple design and are suitable for handling a wide range of materials, including hard and abrasive materials. Gyratory Crushers. Gyratory crushers are larger crushed stone machines that are used to crush large rocks into smaller pieces.

Crushing produces mainly coarse (TSP and PM 10) dust particles which settle near the dust source. The mass concentration of coarse particles varied from few tens of μg/m 3 to over 6 × 10 3 μg/m 3 downwind from the crusher. The mass concentration of fine particles (PM 2.5 and PM 1) ranged between ten μg/m 3 and few hundreds of μg/m 3 ...
