If you use an impact mill or hammer mill, you feed the product that needs to be processed inside the mill through an inlet box found on top and it is already pre-crushed by a main beater tool as the top of the rotor is reached. Moreover, the beaters will have the product accelerated and move it right through the milling zone proper near the rotor’s side. The grinding stock will then be fluidized inside the air flow and will be comminuted by the grinding tools (stator or rotor). Stator is made by a covering that encloses rotor. Inside this cover is provided with toothed grooves that run vertically that is crosswise to the sense of rotation to the rotor.
Outside the rotor, it is being covered by various U-shaped sections that form in to some deep cassette-type of structure. Furthermore, this geometry then produces an extreme whirls of air inside the grinding zone of the rotor that induce an intense secondary comminution courses because the particles are crashing right into each other and also due to the shearing forces and friction. You can adjust your hammer mill’s final particle size from a wide array. This is done by modifying the rotor speed, grinding rotor clearance, and the air flow.
Aside from pulverization in the <100 um range, its impact mill truly demonstrated a highly reliable as well as efficient when taking out fibers from the organic substances including cellulose, paper and paperboard. It is also very much reliable in cryogenic grinding, grinding or drying, grinding-coating and combined grinding and blending.
In the market, there are different hammer mill varieties being sold. As the buyer, you need to ascertain from whom you should buy and the kind of hammer mill that your company needs. When choosing the right mill for your company, you can seek the assistance of experts or professionals who have ample experience in the industry. There are the so-called micro-grinding impact mill systems which are typically designed to be efficient, fast and long lasting.
You can also choose the freestanding 16 inches hammer mill which is designed specifically for larger productions of processing ultra-fine pulverization of materials. The equipment can produce as fine as 200 mesh which would be dependent upon the material. The 11 inches bench unit is also out in the market and can produce some 100 mesh fineness during the first pass. Every hammer mill has two outlets for the removal of ore.
These outlets will allow you to run the ore dry or wet. For the 11 inches bench unit, the ore bin along with vacuum bag attached will collect the very dry ultra-fine powder as it exits by the top outlet down onto the hose. In running your material wet, you can make use of the bottom outlet or place a cap on the top outlet. Both mills are designed in order to create minimal dust leakage so that there will be an air control of the environment. During 2013, standard units usually come with carbide tipped hammers in order to promote greater wear ability.
