What to decide first
Any four-head automatic liquid filling line has two main jobs: filling bottles in the 10-500ml range and moving those bottles through the process. The two options on the table take different paths to the same result. One is billed as a bottle filler with a belt conveyor; the other is billed as a mini filling line that arrives as a complete package. The listed price difference is about USD 15.64, so the deciding factor should be which package style fits your floor and how much specification detail you want up front.
Quick verdict
If you want a bundled system-filling machine host, conveyor belt, and assembly accessories-the mini filling line is the straightforward choice. If you want the conveyor called out in the product name and a fuller set of electrical and bottle-size specs, the belt conveyor version is the better match. Both are listed as new, so the comparison stays about setup and detail rather than condition.

Where each configuration wins
Prefer the belt conveyor version if...
You want the conveyor and the filler treated as one visible package. The belt conveyor version also comes with stated specs for the tabletop setup: US-standard 110V plug, 150W power, a 20-90mm bottle diameter window, and a 40-250mm bottle height window. Those numbers make compatibility checks easier.
Prefer the mini filling line if...
You prefer the idea of a ready-to-assemble line in one package. The mini filling line includes a filling machine host, a conveyor belt, and all assembly accessories, with a build that uses a stainless steel mainframe and aluminum spacer.
Product notes
4-Head Automatic Liquid Filling Machine Bottle Filler w/ Belt Conveyor 10-500ml
This option puts the conveyor front and center, so there is no guesswork about what the setup is supposed to look like. The specs go further: it runs on corded electric power with a US-standard 110V plug, draws 150W, and is built for bottle sizes from 20-90mm in diameter and 40-250mm in height. Those are useful numbers if you are comparing against your existing bottles. The natural limitation is that the setup is tied to those container windows and that plug standard. If your bottle diameter or height falls outside that range, or your power outlet differs, this configuration would not be the right match.
4-Head Automatic Liquid Filling Machine Mini Filling Line 10-500ml Bottle Filler
This is the complete-line presentation. The package is built around a filling machine host and conveyor belt, with all assembly accessories included, so you can treat it as a single project. The build uses a stainless steel mainframe and aluminum spacer, which gives it a sturdy, rust-resistant feel. The trade-off is that the technical focus stays on the complete package and durable construction rather than electrical specs, so it works best when you already know your power setup and bottle dimensions.
Final choice by use case
Choose the 4-Head Automatic Liquid Filling Machine Bottle Filler w/ Belt Conveyor 10-500ml when you want the filler and conveyor identified together and you want electrical and bottle-size parameters spelled out before you commit.
Choose the 4-Head Automatic Liquid Filling Machine Mini Filling Line 10-500ml Bottle Filler when you want a bundled host-plus-conveyor package with assembly accessories and a durable build story, without needing every electrical detail up front.
