Hello every one!I recently back from a trip around few of the most important engineering manufacturer equipment in europe and i found out that(at least in 3 of them) they were using tooling not available on the market for privates and meant for the industries,so i found out one of these brands named Freutek, a german/italian company and i have to say they have some serious stuff there but ...

A grinding machine or grinder is an industrial power tool that uses an abrasive wheel for cutting or removing the m aterial. It is a process of metal cutting by using a rotating abrasive whee l from the surface of the workpiece. Generally, the grinding is finishing operation to show the high surface quality, accuracy of the shape and dimension.

After that, you will proceed with the grinding process as the hopper releases the cocoa beans into the machine. Step Two: Grinding Process. The cocoa beans move slowly to the grinding zone, where the whole grinding process will take place. Here, the grinding process will proceed with the help of the relative movement from the stator and rotor.

2 The horsepower of the grinding machine can play a role in determining the grade of the bond or the hardness of the wheel. When a machine has a higher horsepower available at the spindle, harder wheel grades are wiser. The harder wheel will hold form and retain the grains as long as possible under the stronger forces.

The bean extraction, bean grinding, and Okara separating processes can be completed at one time, and the soy milk is directly heated. In addition, the concentration of soy milk can be monitored before heating the soy milk, and the programmable parameter settings can be adjusted quickly, so that the concentration of soy milk can be monitored more accurately and easier to control the quality.

Machining is a term used to describe a variety of material removal processes in which a cutting tool removes unwanted material from a workpiece to produce the desired shape. The workpiece is typically cut from a larger piece of stock, which is available in a variety of standard shapes, such as flat sheets, solid bars, hollow tubes, and shaped beams.
