The equipment that can accept the maximum feed size out of the options provided is the jaw crusher. Here's a brief overview of each equipment type:

1. Jaw Crusher:
   • Jaw crushers are typically used as primary crushers and can handle large feed sizes, often up to several meters in size.
   • They work by compressing material between a stationary piece and a moving piece of metal.
2. Ball Mill:
   • Ball mills are used for grinding materials into fine powder.
   • They typically accept feed sizes that are smaller, usually in the range of 1-2 cm.
3. Tube Mill:
   • Tube mills are similar to ball mills and are used for grinding purposes.
   • They generally accept similar feed sizes as ball mills, typically around 1-2 cm.
4. Jet Pulveriser:
   • Jet pulverisers use high-speed jets of air or steam to grind materials into very fine powders.
   • They usually require very fine feed sizes, often less than a few millimeters.
