The mechanical process
The solid materials are grounded after being exposed to mechanical forces. The force overcome the interior binding forces of the material and pounce it into pieces. After subjected into the grinding process, the solid state of the material is changes. The grain size, shape and disposition are all altered. When employing the use of process engineering, there are several factors that play an important role and are as follows: magnification of the solid material’s surface area, allowing the material to undergo the pulping process to achieve the desired state and manufacturing of the solid material with the desired grain size.
Types of grinding mills
The different types of grinding mill include the mortar and pestle; and the grain mills.
Mortar and pestle
The mortar and pestle is used to mix and grind substances including food and chemicals when in the laboratory. The pestle is a heavy and small bat that is usually made from wood, porcelain or other materials. The pestle has a round end and is used in pounding and grinding. The mortar on the other hand is a bowl which is typically made from wood, porcelain, stone or other materials. The substance that needs grinding is placed in the mortar and is grounded by pounding the pestle against the mortar. Do this continuously until you grind the material into fine powder.
What are grain mills? A grain mill is a home tool that is used to grind wheat berries into flour. There are plenty of flour mills in the market to choose from. You can begin your search for the right mill to purchase using three basic decisions: the right milling mechanism, the appropriate power source to use and the maximum flour temperature that can be tolerated. There are plenty of mills out there that are handy and useful in a family set-up as well as in a business type of set-up. Your decision will have to be determined by the quality, price, convenient features and the versatility of the product.
If your primary objective is to get the flour grounded without any frills and hassle on your part, it is recommended that you use an electric mill. However, one drawback to this machine is that it cannot be used during power outages.
If you are not comfortable with an electric mill, you can opt for convertible mills. There are plenty of mill manufacturers that have devised ways in order to make the mills convertible from electric to manual and vice versa.
