The working principle of the self-grinding machine is basically the same as the ball mill, the biggest difference is that the sag grinding machine uses the crushed material inside the cylinder as the grinding medium, the material constantly impacts and grinding to gradually pulverize. sometimes, in order to improve the processing capacity of the mill, a small amount of steel balls be added appropriately, usually occupying 2-3 of the volume of the mill that is semi-autogenous grinding.

Ball mills are fine grinders, have horizontal ball mill and vertical ball mill, their cylinders are partially filled with steel balls, manganese balls, or ceramic balls. the material is ground to the required fineness by rotating the cylinder causing friction and impact. the internal machinery of the ball mill grinds the material into powder and continues to rotate if extremely high precision and precision is required.

The biggest characteristic of the sag mill is that the crushing ratio is large. the particle size of the materials to be ground is 300 400mm, sometimes even larger, and the minimum particle size of the materials to be discharged can reach 0.1 mm. the calculation shows that the crushing ratio can reach 3000 4000, while the ball mill8217s crushing ratio is smaller. the feed size is usually between 20-30mm and the product size is 0-3mm.

It was important to us that the pepper mill had adjustable settings that allowed for both coarse and fine grindsand options in between. sometimes you want crunchy flecks of pungent pepper. other times you want a smooth grind that blends well with salt and disappears into a dish. a good pepper mill will allow for a range of coarseness, with each setting producing a uniform grind.

A classic pepper mill operates by twisting the top portion of the mill, which activates the rotating blade at the bottom of the mill via a metal rod. the pepper gets pushed down and rotated through the blade. however, some models we tested operated by twisting a metal crank or by pushing down on a lever. in our testing, we found that the classic method of twisting at the top was the most comfortable and easy to use.
