1. Ball mill is the key equipment to crush the material after it is crushed. This type of mill is filled with a certain number of steel balls as grinding medium in its cylinder. It is widely used in cement, silicate procts, new building materials, refractories, chemical fertilizer, black and non-ferrous metal mineral processing, glass ceramics and other proction instries, dry or wet grinding of various ores and other grindable materials. Ball mill is suitable for grinding all kinds of ores and other materials. It is widely used in mineral processing, building materials and chemical instry. It can be divided into dry grinding and wet grinding. According to the different ways of ore discharge, it can be divided into grid type and overflow type
rod mill is a kind of mill in which the grinding body is steel rod. Rod mill generally adopts wet overflow type, which can be used as first-class open circuit grinding. It is widely used in first-class grinding of artificial sand, concentrator, chemical plant and power department. The mill is mainly composed of motor, main recer, transmission part, cylinder part, main bearing, slow transmission part, feeding part, discharging part, ring seal, playful voice station, big and small gear spray lubrication, foundation part, etc. The main recer has parallel shaft and hard tooth surface. The rod mill is an asynchronous motor connected with the pinion through the recer, which directly drives the peripheral big gears to decelerate and rotate, and drives the rotary part to rotate. There is a suitable grinding medium steel rod in the cylinder. Under the action of centrifugal force and friction, the grinding medium continuously enters the cylinder from the feeding part and is crushed by the moving grinding medium, And through the overflow and continuous feeding force, the proct is discharged out of the machine for the next process. Its working principle, structure, type, grinding medium, application, installation and installation precautions are introced in detail.

The motor of ore crusher drives the rotor to rotate at high speed in the crushing chamber. The material is fed into the machine from the upper feeding port and crushed by the impact, shearing and grinding of the hammer moving at a high speed. The device can adjust the gap between castor bars according to the user's requirements and change the discharging particle size to meet the different needs of different users. It has the characteristics of simple structure, large crushing ratio and high proction efficiency. It can be used for dry and wet crushing. The main working part of the machine is the rotor with hammer (also known as hammer head). The rotor consists of spindle, disc, pin and hammer. The motor drives the rotor to rotate at high speed in the crushing chamber. The material is fed into the crushing cavity from the upper feeding port, and is crushed by the impact, impact, shearing and grinding of the high-speed hammer. In the lower part of the rotor, there is a sieve plate. The stone particles smaller than the size of the sieve hole are discharged through the sieve plate, and the coarse particles larger than the size of the sieve hole are kept on the sieve plate and continue to be hit and ground by the hammer, and finally discharged out of the machine through the sieve plate
3. Ore small particle crushing, a lot of machines can be used, electromagnetic ore crusher, disc crusher, sample preparation grinder..... Our laboratory is using the sealed sample preparation grinder of Hangzhou Lantian laboratory instrument factory
4. Gold deposits in China are mainly divided into native gold and silver gold deposits, and a few of them also contain tellurite gold and black bismuth gold. Among them, some gold mine owners regard gold telluride as the main economic mineral, which is not surprising under the special distribution of gold deposits mentioned above in China. At present, the commonly used gold ore dressing method is to crush the gold ore by gold crusher (traditional crushing equipment or professional gold crusher), then crush it by gold grinding equipment (traditional grinding machine or special gold grinding machine), and then treat it by classifier, mixing bucket, chute, flotation machine and other equipment, and extract concentrate and tailings by gravity separation and flotation, Then, through chemical method and smelting, the proct finally becomes finished gold.
5. I used the planetary grinder of Changsha Tianchuang powder. The automatic planetary grinder is relatively high. I don't know what you want to do with this formula. Generally, I won't tell you.
6. Is it a single crushing or extraction of
iron concentrate? If single crushing with
jaw crusher
is OK,
box crusher
is also OK, if iron ore dressing with grinding equipment and cleaning equipment, Zhengzhou

7. In chemical changes, molecules can be subdivided, but atoms can not be subdivided; B. When water is heated to boiling, it turns into gas; C. The smell of flowers is the movement of molecules, no new substances, physical changes; D. When heating the mercury oxide, the mercury oxide molecule is decomposed into mercury atoms and oxygen atoms, the mercury atoms are combined to form metal mercury, and the oxygen atoms are combined to form oxygen molecules, which fully shows that the mercury oxide molecule is formed by the combination of mercury atoms and oxygen atoms
8. Equipment: vibrating feeder, jaw crusher, cone crusher, vibrating screen, ball mill, spiral classifier, magnetic separator, dryer, etc
process flow:
crushing and screening: e to the high hardness of iron ore, there are some requirements for the selection of crushing equipment. Large iron ore can be evenly sent to jaw crusher by vibrating feeder for coarse crushing, and the appropriate size of blocks can be sent to cone crusher for secondary crushing. After crushing by cone crusher, the fineness of materials can reach 0-12mm, After sieving by vibrating screen, it will be ground in the next grinding process
grinding: the choice of iron ore grinding machine is mainly ball mill. The materials from the upper level are evenly and orderly sent to the ball mill for grinding, and then screened by the spiral classifier. The qualified materials are eliminated, and the unqualified materials are returned to the grinding room for regrinding
precautions: it has to be emphasized that ball mill is the best choice for iron ore mill. Although Raymond mill, high-pressure mill and European plate mill can also be used for crushing, considering the demand of finished procts, output and secondary beneficiation process, ball mill is the most suitable. It is also clearly stated in the instructions for most mills that Raymond mill and other vertical structures are grinded by grinding roller and ring, It is not the crushing of metal minerals, inflammable and explosive ores
magnetic separation process: because there are many impurities in iron ore, impurity removal treatment must be carried out. Magnetic separator can effectively remove impurities and ensure the quality of finished procts
precautions: there are many kinds of impurities in iron ore, which are difficult to remove, and some of them are harmful impurities, which will not only damage the performance of iron ore itself, but also seriously affect the later use performance of iron and steel procts, such as sulfur, phosphorus, arsenic, potassium, sodium, fluorine. Phosphorus is easy to break in iron ore smelting, which leads to cold brittleness, and some manganese, nickel, chromium, vanadium, titanium and other beneficial elements, It can improve the performance of the finished proct to a certain extent
drying treatment: drying treatment is the last process of iron ore processing, and high quality iron concentrate can be obtained from the dried iron powder
ironmaking process has a long history in China. Iron and steel is also a necessary raw material for proction and life. At present, the iron and steel market is in a state of slow recovery, but the road ahead is still thorny. In order to change the development status of the iron and steel instry and promote its development progress, we should improve and innovate in the mining, processing, utilization and other environment, all with low carbon, environmental protection and energy saving as the premise, Stable and effective development.
