Correia transportadora vs. esteira transportadora vs. tapete rolante
While correia transportadora, esteira transportadora, and tapete rolante all translate to "conveyor belt", their usage differs significantly based on the region (Brazil vs. Portugal) and the specific context (industrial, commercial, or public transport).
Correia transportadora
C1This is the most technical term, focusing on the actual mechanical loop or strap (the rubber or fabric material) that moves things. It is commonly used in industrial settings, distinct engineering contexts, and mining operations to describe heavy-duty machinery.
A borracha da correia transportadora precisa ser substituída imediatamente.
(The rubber of the conveyor belt needs to be replaced immediately.)
Essa máquina utiliza uma correia transportadora para mover o carvão.
(This machine uses a conveyor belt to move the coal.)
O técnico verificou a tensão da correia transportadora.
(The technician checked the tension of the conveyor belt.)
Esteira transportadora
B1In Brazilian Portuguese, this is the standard, all-encompassing term for almost any moving belt system. It applies to factory assembly lines, luggage carousels at airports, checkout counters at supermarkets, and even exercise treadmills.
Por favor, coloque suas compras na esteira transportadora.
(Please place your groceries on the conveyor belt.)
Minha mala demorou muito para aparecer na esteira transportadora.
(My suitcase took a long time to appear on the conveyor belt.)
A produção parou porque a esteira transportadora quebrou.
(Production stopped because the conveyor belt broke.)
Tapete rolante
B1In European Portuguese, this is the common term for luggage carousels and supermarket belts. However, in both Brazil and Portugal, it also distinctly refers to moving walkways—the flat, motorized belts at airports used to transport standing people horizontally.
Os passageiros usaram o tapete rolante para chegar ao portão de embarque mais rápido.
(The passengers used the moving walkway to get to the boarding gate faster.)

(Remove the luggage as soon as it arrives on the conveyor belt.)

(The cashier's conveyor belt was dirty with milk.)
Summary
Use correia transportadora for technical or industrial focus on the belt mechanism. Use esteira transportadora as the default word in Brazil for factories, airports, and supermarkets. Use tapete rolante as the default in Portugal for commercial belts, or globally when referring to moving walkways for people.
