Classic Hand Operated Mill

We all know the expression “Daily Grind” wasn’t coined as something to look forward to. However, where coffee, wheat, corn or spices are concerned, the daily grind can and should be one of life’s greatest simple pleasures. The rich, spicy aroma created by the grinding of fresh roasted coffee is nothing short of amazing. Grinding coffee, corn or spices can be not only enjoyable, but a relatively simple affair on our hand operated grain mill.

DIAMANT D.525 Hand-mill for all kinds of hard Grain

Our hand-mill is suitable for grinding of any kind of grain, corn, coffee, chemicals, spices, etc. and with this mill you will easily get fresh, wholegrain flour for your homemade bread.

The D.525 Grain Mill is Easily Operated

DIAMANT hand operated grain mill type D.525 is a strong mill which is designed to meet the requirements of a small hand-operated mill, easy to operate by means of hand power. No special tools are required.

This hand operated grain mill mill can be used for grinding of products with a high moisture content as it can easily be opened and cleaned without any special tools. Due to the special force-feeding worm the mill is suited for grinding products with a certain oil content.

Electric Motorised V Pulley Flywheel

The flywheel has a V groove for the V-belt drive and can be driven by an electric motor. We do not supply the motor, but recommend a 1 HP motor, 1400 r.p.m. and a pulley of 85-90 mm for the motor shaft, making the rotation of the grinding disc approx. 300 r.p.m.

Mill Specifications  

Steel Grinding Discs

The heart of the mill consists of the specially cast and hardened grinding discs. They are supplied in various types depending on the purpose. Type 14/15 for normal grinding,  type 14a/15a for finer grinding and type 16/17 for animal feed and cereal.

Distance Adjustment of Discs

The distance between the discs is adjustable so the grinding fineness can be changed during operation.

Unique Pre-Grinding System for Superior Results- Only the Diamant has it! Several blunt pre-grinding “”teeth”” gently crack grain. When it gets to the auger it’s perfectly prepared for a smoother, more even grind. Competitor models use an impractical spring arrangement that’s not nearly as effective and completely lacks the elegant engineering of the Diamant.

Grinds fast and fine – Extra large burrs churn out flour as fine as store-bought 20 percent faster and much more easily than any other hand-turned mill on the market.

Easy to use:

  • The large flywheel is made of solid cast iron, not aluminium. It adds momentum to the rotation, turns smoothly and can be easily motorised in the version with belt V-groove.
  • Adjusts quickly and easily from powder-fine to coarse.
  • Long wooden handle lets you use two hands for more leverage. Or share the work with a friend (face each other). Grinding is much easier – and more fun – with two people!
  • Bushing/sealed bearings eliminate maintenance – never need to be oiled!

Built to last – This mill hearkens to an earlier time when things were built to outlast their owner and be passed on to the next generation. Solid cast iron mill is one of the heaviest hand mills in the world. Non-toxic green finish with gold trim, force-feeding worm auger pre-cracks grains, three kinds of burrs add versatility, one-year warranty.

Note: After grinding oily or fatty foods, it may be necessary to demount the mill and clean the mill casing, cover and grinding plates. The mill comes with instructions on how to do this. If you are storing the grinding plates for several months in a humid environment, it’s a good idea to coat them lightly with vegetable oil to prevent rust. With normal use, the grinding plates should last for many years.
