In the mine beneficiation industry, all kinds of mineral processing equipment can be seen everywhere, especially the beneficiation ball mill
. Whether it is a magnetic separation production line, a flotation production line, or a metal smelting production line, this article will introduce you today. A more common model - 2200 * 7000 beneficiation ball mill.
Model parameters of 2200*7000 beneficiation ball mill
Dimensions: The 2200*7000 beneficiation ball mill is a large and medium-sized horizontal cylinder with a diameter of 2.2 meters and a length of 7 meters. It mainly relies on the rotation of the cylinder to give the grinding material and the grinding medium a certain speed and height. It satisfies the conditions of falling or throwing from a height, thereby completing the collision-crushing-grinding-forming process.
Internal grinding media: The grinding media of the ball mill are three kinds of steel balls, steel bars and ceramic balls. Among them, ceramic balls and steel balls are finely ground, steel bars are coarser, and each grinding medium has many specifications. Proportional mixing and grinding of different specifications can obtain different grinding effects, depending on actual production conditions.
Grindable material type: size 2200*7000 dressing ball mill can grind limestone, iron ore, copper ore, gold ore, tungsten iron ore, calcite, diabase, dolomite, lime clinker, not more than 25mm Hundreds of metal ore and non-metallic ore materials in the natural world such as slag and coal gangue have a wide range of applications.
To what extent can it be grounded: different materials in the natural world have different grinding difficulties, some are easy to grind, some are difficult to grind, and the material can be ground to 0.074-0.833mm, easy to grind material according to the material's easy to grind and hard-grinding properties. The time it takes to grind to the specified standard is shorter, and the time it takes to grind the hard-to-grind material to the specified standard may be longer, the coarse grinding time is shorter, the yield is higher, the fine grinding time is longer, and the yield is slightly lower.
Cylinder rotation speed: The cylinder rotation speed is a special parameter setting, which seems to have nothing to do with the grinding material, but it is an important factor to determine whether the material can be successfully ground to the specified standard. The cylinder rotation speed is not how to turn it. It doesn't mean how fast it will turn. At the beginning, its value has been designed. We just need to follow the instructions. The cylinder speed of the 2200*7000 beneficiation ball mill is 21.7 laps per minute.
The amount of grinding: related to the fineness of the grinding, the finer the grinding material requirements, the smaller the grinding amount. However, the fineness of the grinding is not infinitely small, and it has a discharge range, so the grinding amount of the ball mill is determined according to the grinding requirements, and is between 15 and 28 tons per hour.
