They are used to divide resources between two belts, or balance Splitters are a 2×1 entity that splits incoming items on beltsįrom up to two input to up to two outputs, in a 1:1 ratio. Splitters are another form of item manipulation. This has several advantages: Firstly the throughput of the belt-car-boxes is amazingly high, secondly the inserter stack size bonus does apply here and makes inserters more effective. So, they can be used as moving boxes on belts. Cars have an inventory and can be filled by inserters. That way more turrets can attack a single spitter at once.Īnother useful usage is cars on transport belts. Secondly, spitters can be moved closer to your walls. Firstly, biters will have a harder time to reach your walls when placing express transport belt in front of them. This can be abused to improve your defense. Additionally, biters and spitters can be moved. However, the player is not the only unit that can be moved by transport belts. That is why building a belt towards your defenses can be beneficial. Running on a belt will increase or decrease the movement speed of the player accordingly to the belts speed. Moving fast can be essential to defend alien attacks in time. Simply place more belts carrying the item that needs throughput. More belts Adding additional parallel belts can also increase the throughput. In most cases, this will be the place where belt optimization is needed. There will be a part of the belt where the items don't move quickly (or at all) or stop at maximum density and suddenly they come to a point where this 'stop and go' effect releases itself, the bottleneck has been found. Finding the bottleneck is the first thing that needs to be done, usually it can be discovered quite easily. More speed If the belts in the factory are already at maximum density, their speed can still be upgraded with better belts. The squashed gap is extended to normal size once the front of the belt starts to move again. However, mining drills, inserters, and belt sideloading can still force an item into these gaps, temporarily squashing the items on the belt. More density Sometimes items have small gaps in between each other that aren't big enough for other items to fit in. So, there are three opportunities to enhance the throughput: It describes how many items pass by at a given time. Density How tight are the items put onto the belts each straight belt piece can hold exactly 8 items. This is 1.875, 3.75 and 5.625 for basic, fast and express belts. Speed How fast a belt moves in tiles per second. Maximizing the throughput means ensuring that as many items as possible are transported. For further explanation of the mechanics, see lane balancers.Ĥ stack inserters can compress an express belt at stack size 12 for the left inserters and stack size 8 for the right inserters. The former only works if only one lane is in use initially.

The gifs below show two ways how to do this. Maintain throughput, balancing the lanes may be necessary. The trick in the second gif is better described in the underground belt section.ĭue to how items are placed onto belts by inserters, their lanes can sometimes become unbalanced. It is also possible to unmerge a mixed belt by using underground belts since an underground belt will block half of the belt.īelts going across a splitter will have items from the splitter moving to one side of the crossing belt.Ĭommonly, merging and un-merging is done by using a splitter. The belt can be unmerged using a splitter filter. Smelting ore, or producing items with many different ingredients such as Utility science pack. This allows for either a double flow of one material, or to transport two different materials on the same belt. Belt mechanics Merging and un-merging beltsīelts of all tiers have 2 lanes for items to ride on.
