A flameproof vibro sifter uses a flameproof motor and electrical construction so the machine can be used in areas where flammable solvent vapour or combustible dust may be present. Sterial Machinery offers flameproof construction across its vibro sifter range, including double and triple deck machines.
Where Flameproof Construction Is Needed
- Pharmaceutical granulation areas using alcohol or other solvent binders.
- Sifting of solvent-damp or recently dried material.
- Bulk drug (API) plants handling solvents.
- Chemical, pesticide and pigment plants with combustible dusts.
- Any area classified as hazardous by the plant's safety assessment.
What Changes in a Flameproof Vibro Sifter
- Flameproof vibro motor in place of the standard motor.
- Electrical connections and controls suitable for the specified area.
- Earthing provision to reduce static charge build-up on the machine.
- Same SS 316 contact parts, screens and mechanical design as the standard sifter.
Information to Include in Your Inquiry
- Material and solvent being handled.
- Hazardous area classification of the installation area.
- Required gas group / temperature class if specified.
- Model size and number of decks.
- Power supply details.
Flameproof Model Range
