High Pressure Grinding Roller (HPGR) has become an increasingly popular solution in the U.S. for processing of rough-hewn stone and other solid organic compounds in high volume. In particular rough coarse ores like Galapagos granite, marble and limestone are suitable for high-pressure grinding, because these materials contain small particles that are difficult to chip using conventional grinding methods. In order to increase productivity and profit from the high volume of processed material that HPGR can produce, companies must use more machines, including diamond-tipped grinders and electric shredders. But despite these benefits, it is important to keep in mind that the potential for damage to the grinding equipment when rough rocks are used in these machines is always a risk. This is especially true when fine particles of irregular shapes are involved.
One of the common causes of equipment damage in
high pressure grinding rollers is due to incomplete closing of the cutting edges of the wheels or an ineffective, poorly sized cutter. Both of these issues, coupled with wear caused by abrasions and chips caused by the use of rough water-based compounds, can significantly reduce the life of the machine. When using diamond-tipped, electric, or hydraulically powered high pressure grinding rollers, it is important to properly maintain the machine. The most common cause of damage to this equipment is poor maintenance practices, which include inadequate lubrication of the grinding components and a lack of size reduction.
In addition to poor maintenance, the use of low quality feed material can lead to equipment failure in high pressure grinding roller. Feed material is critical for the proper operation of most high pressure grinding rollers. Corrosion, which occurs with low quality feed material, can also reduce the life of the equipment. Feed material should always be made of graphite, stainless steel, or other high pressure resistant materials.
