Mining
Our mining screens are ideal for coal, iron ore, gold, copper, phosphate, lead, zinc, bauxite, sand, and gravel mining processes. Our screening systems: Remove moisture in coal preparation, which lowers coal heating value. Also, too much moisture leads to handling/freezing problems and increased transportation costs.

CRUSHING SCREENING
The screening process is just as important as the crushing itself. Screens are the heart of every rock processing plant. They are used to classify materials both in different stages of the crushing process and in final product separa-tion. Designed as a non-welded frame with adjustable vibration features for different material types and screening

Screening 101
Screening is the passing of material through definite and uniform apertures is the only true and accurate means of grading to a required particle size. Air separation and hydraulic classification depend upon gravity and particle shape, and result in the segregation and retention of material of higher specific gravity and lower surface area irrespective of size.

Mineral Dust Emissions at Metalliferous Mine Sites
Crushing, milling and screening operations can be major sources of dust due to major reductions in grain size during comminution and segregation processes. Estimates of dust emissions from common mineral processes demonstrate that dust emissions increase as the size of the material processed decreases (US EPA 2004 ).
