Metallic ores generally refer to minerals from which metal elements can be extracted by smelting. Metal minerals can be divided into five types according to their composition, properties and uses: ferrous metal minerals, non-ferrous metal minerals, precious metal minerals, light metal minerals, and semi-metallic minerals. The various types of metal mines are used in different industries and have high economic value.
Most of the metallic ore needs to be processed by crushing, grinding, beneficiation and other processes before it can be applied to the corresponding industrial field.Crushing is the first step of metal ore processing, and it is also an important step.Due to the hardness of most of the metallic ores is relatively high, when selecting the crushing equipment, it is necessary to select a suitable crusher according to the nature of the material. Let us introduce some crushing equipment for metallic ores which is commonly used in the market.
In the production of metallic ores, the jaw crusher is generally used, and the large-scale production unit (especially large foreign mines) adopts a rotary crusher. Jaw crusher is the most traditional and most stable and reliable coarse crushing equipment. It has the widest range of applications and is the preferred crushing equipment for metal ore processing plants. The outstanding advantages of this device are as follows:
(1)It can crush various metal ores such as copper ore, iron ore, nickel ore, molybdenum ore, tungsten ore, and has a large feed port, which can break up large rocks and is not affected by the nature of the ore and the working environment. It is very flexible, and the operation and maintenance work is relatively simple and easy.
(2)The processing capacity of metal ore is relatively large, the output and crushing efficiency are extremely high, and there are no vibration, shutdown and other faults during operation, and the operation is very safe and stable.
(3)The sturdy frame of the jaw crusher can be operated under high-strength pressure, while the high-manganese steel has strong toughness and firmness, such as movable jaws, jaw liners, heavy-duty eccentric shafts and large bearings which ensure its reliablity and long service life.
The impact crusher is also suitable for the crushing of metal mines, and has good pertinence and professionalism. The biggest advantage of this equipment is that it is smaller in size and lighter in weight, so it is more convenient to install and operate, and the degree of automation is relatively high. The realization of the unmanned ideal production state can save the investment factory a lot of manpower and material investment costs. In addition, the price of the impact crusher is relatively economical, and the cost performance is higher, which can achieve higher returns.
The cone crusher is one of the most advanced crushing equipments at present. Our cone crusher adopts the new concept of crushing technology, which can meet the crushing of different material specifications and meet the requirements of the new process of “multi-breaking and less grinding”. The machine not only has a large crushing ratio, but also has a fine and uniform particle size, and low unit power consumption. There is no requirement for the humidity of the crushed material, and it is also suitable for crushing any hard brittle material, and can be used for crushing various minerals.
The above are several crushers which commonly used for metallic ores.It can be selected according to production needs and budget to maximize economic benefits.
