These are paddle type mixers for handling powder materials along with water addition.
Pugmills are used as secondary pollution control equipment where the collected dust is to be conveyed and discharged with water addition. For capacity upto 20-30 TPH single screw Pugmill is recommended. For larger capacity twin screw Pugmills are preferred.
Pugmills differ with screw conveyors in the following manner:
Capacity | 100 TPH or more |

Trough type | U- type |
Trough liner | Abrex/ Sailhard/SS |
Paddle material | Abrex/SS/Hard faced |

Drive | Motor-Gearbox-Coupling |
Shaft seal | Gland packing with provision for nitrogen purging |

Twin Screw mixers are used for solid-solid mixing. These are very much similar to Pugmill except that no water spraying system is required.
