Vibrating Screen: The Silent Killer of Your Profit

I completely understand your Situation. After all, you have invested considerably in this equipment, haven 't you? But everyone in this industry knows the Problem quite honestly: if the vibrating screen is the bottleneck, you will only accumulate expensive, unsorted soil.

I have experienced this many times before—operators struggling with insufficient power and finally solve the Problem by simply adjusting the angle of inclination by only 5 degrees. DBM not only delivers steel materials, but also the sorting accuracy itself, which directly affects the profitability of your company.

By the way, why a circular motion? Why not a linear movement?

When sorting hard rock, correct sorting is impossible if the stones do not "dance". This is the reality. The powerful throwing motion of a circular vibrating screen simply cannot reach a linear screen.

DBM 's YK series is designed precisely for this high-frequency "ideal point". It keeps the raw material in constant motion and ensures that every stone settles in the right place. Blockages are a thing of the past. You get clean, sorted minerals that can be processed directly.

Manganese steel vs PU (polyurethane): The honest choice

Choosing the wrong screen cloth is a common mistake made by beginners. These parts are exposed to harsh conditions, so there are essentially only two options:

Manganese steel: the absolute Standard in heavy secondary crushing. There is no Alternative. Its shock absorption is second to none.
PU (polyurethane): Are you tired of sludge removal every two hours? Switch to PU. It 's flexible and quiet. To be honest, it 's the best for micro sorting.

The cost of acquiring high-quality equipment is obviously high, but how does it compare to the cost of shutting down the entire plant every 48 hours for parts changes? This is far more expensive.

The following three points must be set correctly:

The mere rotation of the motor is not enough. To improve processing capacity, watch these:

Angle of inclination: Are 15-20 degrees too flat? Aren 't the stones moving too steeply? They fly away before they can be sorted.
Frequency: High-frequency vibrations are suitable for particle size separation.
Amplitude: A clear "jump" is necessary, especially for large rock fragments.

This is a simple law of physics.
