Gump 777-E

• Used for grinding various dry products in food processing.
• Suitable for milling grains, spices, and other granular materials.
• Applicable in industries requiring precise particle size reduction.
• Utilised in coffee processing for different grind consistencies.

Typical throughput

For this class of roller mill, throughput can vary significantly based on product and desired grind, but units of this type commonly achieve hundreds of kilograms per hour.

Power supply

Units of this vintage and capacity typically require a three-phase industrial power supply, commonly 400V, 50Hz in the UK.

Grind range

Roller mills like the Gump 777-E are known for their versatility in producing a range of particle sizes, from fine to coarse.

Construction material

Industrial roller mills are generally constructed from robust materials such as cast iron and steel for durability.

Footprint

The footprint for a roller mill of this capacity can be substantial, requiring dedicated floor space within a processing facility.

Maintenance requirements

Regular maintenance, including roller inspection and adjustment, is crucial for optimal performance and longevity of roller mills.

• What products can this type of roller mill process?

  Roller mills are typically used for dry, friable products such as grains, coffee beans, spices, and other granular materials where a consistent particle size is required.

• What are the advantages of a roller mill over other grinding methods?

• Is it possible to adjust the grind size on a Gump 777-E?

• What spares are typically required for a vintage roller mill?

• What kind of installation considerations are there for a unit of this size?

Food processing mills are valued for consistent particle size reduction across grain, spice and dry ingredient applications. Buyers typically prioritise motor condition, grinding chamber cleanliness and wear on grinding elements when purchasing used equipment. Industry sentiment highlights reliability and longevity as key strengths, particularly with well-maintained units. Attention should be given to throughput capacity matching production needs and compatibility with existing systems. Corrosion resistance matters for hygiene-sensitive environments. Reputable machines from established manufacturers generally command buyer confidence in the secondary market.
