Why choose a Peppink beater cross mill instead of a hammer mill?
A Peppink beater cross mill is ideal for fine milling. For the milling of products with high capacity, but lower requirements for the fineness and grain distribution, a hammer mill can be used as well.

When is a Peppink Pen Mill applied?
A Peppink Pen Mill is interesting when very high fineness is required, or when products with a high fat content are milled. When the grinding disks rotate in opposite directions, the mill does not clog up with fat, due to the centripetal forces. The disadvantage of the Pen Mill is the relatively higher energy consumption and the heating of the product.

Are Peppink AN mills suitable for an ATEX zone?
Peppink AN mills are produced from cast iron, which makes the mill cheaper and more reliable. When ductile cast iron or stainless steel is used, a Peppink AN mill is Explosion Shock Resistant up to 0.5 bar (ExPSR up to 0.5 bar) and suitable for use in an ATEX zone 22. Older Peppink AN mills are usually cast in gray laminar cast iron. These mills are not suitable for use in an ATEX zone 22.

Why are Peppink AN mills not available in welded steel?
The Peppink AN mills are usually cast in series and tooled by machines, which is favorable for the cost price. If a standard cast Peppink AN mill is not sufficient, a welded version can be chosen. This mill can easily be adapted to specific needs. Peppink then speaks of a W-type mill. The Peppink W mills can be built in larger dimensions both ExPSR and ExPR up to 0.5 bar (on request ExPSR up to 10 bar). Wall thicknesses of the mill are calculated according to the PED, in the same way the wall thickness of pressure vessels is calculated.

To what fineness can a Peppink Mill mill products?
This depends strongly on the settings of the mill and the product to be milled. Product that is easy to mill can be milled to a finenesses of <50 microns. A good example of this is sugar.

What explosion pressure is the Peppink mill designed for?
The Peppink mills for an ATEX zone 22 and 21 are designed ExPSR or ExPSR up to 0.5 bar. The hopper under the mill must be equipped with an explosion relief valve, which ensures that the overpressure caused by a dust explosion is diverted.

What is the difference between a beater cross mill and a cross beater mill?
There is no difference, both terms can be used. The term beater cross mill is mainly used.
