Which is a revolving screen?
Which is a revolving screen?
A screen consisting of a cylindrical (sometimes conical) screening surface mounted on a revolving frame for sizing coarse material; it is still common in gravel-washing, coal-washing, and stone-treating plants, but is not widely used in ore dressing.
How fast should a trommel spin?
The rotational speed of the trommel is critical for safety. About 20 or 25 rpm would be plenty. Plus, lowering the machine’s speed would increase its torque—the twisting force that creates rotation—allowing Brian to sift larger piles of compost.
Why choose dodove trommel screens?
DOVE Trommel Screens are designed for high performance screening, classification and grading applications. Largest processing capacity range in the history of mining industry. Unique screen design results in higher capacities, up to 4 times longer life and more efficient screening actions, with no material clogging and blockage of the screen.
What is trommel screening?
Installed at the end of grinding mills and scrubbers, trommel screening is an efficient, mechanically robust method of screening coarse particles, with a trommel screen machine delivering excellent performance over a long service life.
What is the design production rate for trommel screens?
A processing plant may process 30t/hr as an average over an 8 hour day, however if in 15mins the material inflow could be 10 tonne, which equals 40t/hr. In this case the design production rate must be the peak rate of 40t/hr. Trommel Screens can be built with a combination of the following specifications:
Why choose Multotec trommel screens?
Multotec provides tailor-made, process-specific heavy duty rotary drum screens in several forms to optimise drainage and sizing requirements. Using Finite Element Analysis (FEA) across the complete trommel screen design allows Multotec to calculate the stresses in the structure for a full rotation in order to optimise the fatigue life.
