emission factors for tertiary crushers, screens, and con-veyor transfer points indicate that the pm 2.5 emissions range from 0.000013 to 0.000100 lb/t of stone. the ap42 section 11.19-2 pm 10 emission factors for these three types of processing equipment range from 0.000046 to 0.00074 lb/t. these emission factors provide a starting point for
a variety of material, equipment, and operating factors can influence emissions from 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 above classifications and variables.

the conveyor was contaminating the product. recommendations/solution: to eliminate the carry-back problem within the limited space, the recommendation was to install asgco ® ’s mini-skalper ® iv system with e-z torque ® tensioner. this pre-cleaner is designed for small diameter pulleys where space and size is a factor. asgco ® ’s
the validity of these emission factors is limited to the conditions under which they were obtained. ghose (2004, 2007) based on their own emission factors estimated that a typical open pit coal mine in india with a stripping ratio of 3.98 emitted 9366.7 kg/day of tsp while its production was 2500 t/day ie. 3.74 kg of tsp per mg of coal produced.
the overall emission from mine, besides other factors, depends on mineral production and quantum of overburden handling (chate, 2011). a review of earlier studies on the assessment of the pm emission rate from different mining operations is summarized as a part of this section. overburden removal is the first unit operation in surface mining.
