A Minecraft mob grinder is your personal loot machine, turning mobs into XP and resources. Not only does it save you time, but it also opens up a whole world of farming possibilities. In this Minecraft mob guide, we’ll show you how to build a mob grinder and break down the different types of grinders to help you get the most out of them.

Minecraft mob grinders explained

A mob grinder in Minecraft is an automated system built to efficiently kill mobs and collect their drops. These structures are usually created using spawners, dark rooms, or natural mob spawning mechanics for different purposes:

• Natural Spawning Grinder: Uses dark enclosed areas to spawn mobs, then pushes them into traps (fall damage, lava, or drowning). Best built high up or in oceans to maximize spawns.

• Spawner-Based Grinder: Utilizes natural mob spawners (zombie, skeleton, spider) for reliable spawning. Funnels mobs to a kill zone using water or other mechanics. Commonly used for XP farming.

• XP Farm Grinder: Designed for manual mob killing to gain XP. Mobs are weakened first (fall damage, suffocation) to be easily finished off by players. Ideal for enchanting and repairing gear.

• Passive Mob Grinder: Automates farming of cows, pigs, chickens, and sheep. Uses breeding systems and lava blade cooking for food and resources. Often employs water and trapdoor mechanics.

The grinder then funnels them into a killing mechanism and collects loot using hoppers and chests. 

How to make a mob grinder in Minecraft

You can build a mob grinder in both Java and Bedrock editions, and it works in all game modes. If you're in Survival or Hardcore, gathering materials will take time, so Creative mode can make construction easier. Here are the needed materials:

• 25+ stacks of cobblestone (or any solid block)
• 1 stack of trapdoors
• 4 hoppers
• 4 chests
• 4 slabs
• 2 water buckets
• Torches & scaffolding (optional)

How to build a mob grinder in Minecraft

This simple structure ensures a steady supply of mobs:

1. Build the grinder (Kill chamber)
   • Dig a 2×2 hole, place chests inside.
   • Add hoppers on top, then slabs to trap mobs.
2. Create the well & bridges
   • Build 22-block-high walls around the grinder.
   • Extend 2×8 bridges on all sides with 2-block-high walls.
3. Make the spawning room
   • Fill in bridges to create dark platforms with a roof.
   • Place trapdoors over canals and water at the ends to push mobs down.
4. Optimize & use
   • Light up the roof to prevent outside spawns.
   • Build an AFK room 80 blocks up for better spawn rates.
   • Wait for mobs to fall and weaken, then kill for XP & loot.

Minecraft mob grinder minimum distance

In Minecraft, mobs spawn within a 24 to 128-block radius from the player, with the optimal spawning occurring between 24 and 32 blocks away

How to get mobs to spawn in mob Grinder? 6 tips you should know

• Build a dark, enclosed space: Create a 24-block high enclosed area to allow mobs to spawn. Ensure it's dark enough inside, as mobs spawn in low-light conditions (light level 7 or lower).
• Use water currents and trapdoors: Utilize water currents and trapdoors to funnel spawned mobs into a central kill chamber. Mobs see trapdoors as walkable surfaces, so they’ll walk into them and fall into the grinder.
• Prevent spawning outside: Light up the surrounding area to stop mobs from spawning outside the grinder and interfering with the spawn rates. This ensures the area inside your grinder is the only place mobs spawn.

• Redstone-powered water systems (Java Edition): In Java Edition, use Redstone and Dispensers filled with Water Buckets to periodically flood the spawn area and push mobs toward the grinder. This method prevents mobs from freezing in place and ensures efficient movement.
• Water on scaffolding (Bedrock edition): In Bedrock Edition, placing water on scaffolding helps efficiently transport mobs. Mobs spawn with their feet inside the scaffolding and are immediately pushed by the water into the grinder.
• Dealing with spiders and baby mobs: For spiders and baby mobs that might get stuck in water, use the following tips:
  • Place buttons on every other block to stop spiders from spawning.
  • Use villagers to lure baby zombies into the water flow.
  • Place snow golems to push mobs into the water flow.
  • Build cascading water down a funnel-shaped spawn floor to pull spiders and baby mobs into the flow.

What is the most efficient mob grinder in Minecraft?

The most efficient mob grinder in Minecraft is typically a Spawner-Based Mob Grinder combined with Active Systems for mob movement. This design utilizes natural spawners, like those found in dungeons, to generate mobs consistently. Water streams or dispensers with water buckets can be used to actively transport mobs to a central kill zone, where they are weakened for easy XP collection. 

What is the weakest passive mob in Minecraft?

The weakest passive mob in Minecraft to farm is the Chicken. Chickens have very low health, with only 4 hit points (2 hearts). They can be easily killed with a single hit, making them an efficient source of resources like feathers, eggs, and cooked chicken (if you use lava blades in the grinder).

Additionally, chickens breed quickly with seeds, making them ideal for passive mob farming.
