the screening of damp coal nonetheless remains problematic and low screening efficiencies can result when the surface moisture content of the coal is even moderately high. The problem is caused by fine coal agglomerating or adhering to larger coal particles and being carried over to the screen oversize product as a result.

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.

Having said that, there comes a point when dry screening is no longer viable. For example, powdered coal requires a wet screening …
Screening is a key link in the coal preparation, and flip-flow screening is the important method for achieving efficient classification of fine coal. During screening, the mechanical response of the screen plate caused by materials collisions not only changes its impact mechanical behavior, but also affects the final screening effect.
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.
