is not always justified. A scalping screen used as a finishing or dewatering screen would have a greatly reduced capacity. A finishing screen used as a heavy scalper would also have a greatly reduced capacity. The type of stroke, length of stroke, screen rpm, timing angle, and incline of the screen greatly affect the basic capacity.

Two deck models augment the process while keeping the cost of the equipment range manageable. Meanwhile, the wet "slurry" produced by the sprinkler nozzles necessitates a dewatering stage. Having said that, there comes a point when dry screening is no longer viable. For example, powdered coal requires a wet screening …

2.4. Evaluation of the screening performance. The screening efficiency, S i, and the total mismatched material percentage, M o, were used to evaluate the screening performance. The screening efficiency is calculated as follows: S i = E c + E f - 100 (9) E c = γ c - M c γ c, t ∗ 100 E f = γ f - M f γ f, t ∗ 100.

Screening is a key process for classification of coal into different size fractions (Jiang et al. 2017a; Jiang et al. 2017b; Wang et al. 2019). Over the past fifty years, wet coal screening has been more important compared to dry coal screening, mainly because of good screening efficiency (Sahu, Biswal, and Parida 2009).

The total capacity of a deck is "A" multiplied by the area of the deck in square feet. This is the final result of the multiplication of all the screen factors. 6 "S", the "Incline" factor, depends on the actual slope of each deck and the opening size of the wirecloth.

This "sized" coal can be any length in the two other directions, i.e. slabbing occurs, which in turn gives problems at the next screening and secondary crushing station. In addition grizzly screens block up very easily, thus eliminating their usefulness. Our Odeca Primary Scalping Screen overcomes these problems.
