No. A belt press uses moving continuous belts; a plate filter press uses fitted stationary cloths. See F11 for plate press cloths.
A tighter surface may retain more fines but can reduce flow or blind more easily. Confirm the balance with conditioned sludge.
Check alignment, tension, feed distribution, roller condition and guiding components before attributing the problem only to the belt.
Provide press make and layout, both belt positions and dimensions, sludge type, feed solids, polymer conditioning, roller diameter, tension and cleaning details.
