Iron Ore Crusher

Iron ore mining methods vary by the kind of ore being mined. You can find four major forms of iron ore deposits worked currently, with respect to the mineralogy and geology of the ore deposits. These are magnetite, titanomagnetite, massive hematite and pisolitic ironstone deposits.

Iron Ore Crushing Machine

Iron ore refers back to the ore containing iron or iron compound, which is one of the most important garbage in output of steel. There are many large-scale iron ore area which have high value of exploitation australia wide, Brazil, India, SA, Canada, Ukraine, Liberia as well as other countries. Main iron ores are magnetite,limonite, hematite ore, iron silicate ore, iron silicate mineral, etc. Probably the most widely used crushers in iron ore mining business are jaw iron ore crusher, cone crusher, hammer iron ore crusher and high-efficient iron ore fine crushers, etc. In iron ore mining, consumers usually choose a complete iron ore crushing  production line for better efficiency. Currently, typically the most popular iron ore production line consists of two jaw crushers. After iron ore crushing, the fabric is going to be sent for the magnetic separation, and then in to the ball mill for grinding.

Iron Ore Process Plant

The world’s iron ore resources are concentration australia wide, Brazil, Ukraine, Russia, Kazakhstan, India, the usa, Nigeria, Canada as well as other countries. Nearly all iron ore experiences iron ore processing and it is utilized to make steel. Iron ore processing can be a procedure that contains explosions, shoveling, moving, crushing, grinding, pelletizing etc. Iron ore processing provides a range of coarse sizing that may produce material in 24-inch to .0017-inch particle sizes.

In iron ore crushing and screening process is really a basic connect to concentrator will have an effect on producing indicators. Methods accustomed to include jaw crushing, impact crushing, roll crushing, and pulverizing. To make iron ore size as fine as you can before entering into ball mill, iron ore processors usually are use cone crushers in pre-grinding stage, cone crusher come with an excellent fine crushing power to minish iron ore size. In coarse crushing, 2.1m or 2.2m gyratory crusher is usually being selected, in medium crushing process, processer usually use regular cone crusher, plus fine crushing, short-head kind cone crusher would work.

Tantalite Crusher and Grinding Equipment

Tantalite is group name for minerals with the chemical formula (Fe,Mn)(Ta, Nb)2O6 and it is a brown black, almost completely black orthorhombic shape mineral. Tantalite is located mainly in granite pegmatites also it accumulates up in drifts and after that it’s extracted as Ta ore. Tantalum is really a chemical element found in tantalite which is noted for its hardness and resistant against corrosion. Tantalum is very rare.   In the tantalum processing plant, we have to pulverize the big tantalite into small particle. Then used tantalite crusher machine and tantalite grinding mill to get tantalite powder.

Tantalite Crusher

For your industrial tantalum manufacture, the mining or blasted tantalite, ought to be loaded to tantalite production line through the heavy truck. In the starting point, the tantalite ore ought to be transported into tantalite jaw crusher, impact crusher or gyratory cone crusher for your primary crusher by belt conveyor.Which crushing machine you choise based on the size of the tantalite. After tantalite crushing processing line and the vibrating screen, how big tantalite under 3 inch is going to be transported into tantalite vertical roller grinding mill or tantalite roller ball mill for grinding. How large tantalite above 3 inch is going to be vibrating and recovery for that second crusher process by vibrating screen. The procedure is going to be going on before tantalite ore below 3 inch.

Tantalite Grinding Plant

The pulverizing tantalite ore in the roller ball mill or vertical roller grinding mill or raymond mill, will be grinded into tantalite powder about 0.2 mm while using grinder roll, grinding ring and steal balls (iron shots). The grinded tantalite powder will probably be seem like tantalite slurry. Finally, the tantalite slurry will be pumped to the flotation deck using the fine sulfide ore (0~0.5 mm) going to froth flotation cells for recovery of tantalite powder. Then tantalite powder will be transported into industrial tantalum machine to obtain tantalum.
The tantalite grinding processing plant possess the production capacity from 5t/h to 39tph per unit. The more fine you need the greater less the production capacity will be.

Process of cement ball mills

Traditional methods, the ball mill during the processing of materials usually can play two effects, one is broken effect, one is the grinding effect. General sense, breaking effect can be broken using other ancillary equipment to complete.The ground level of the direct effect of the impact of factors can be attributed to the control of ball speed.

As a general rule, the speed of ball mill mainly from the basic power distribution equipment and gear drive gear and pulley device control.For large ball, since the drive motor to start the beginning of a great loss when the energy, and because the ball inertia force can not effectively use reducer mill to effectively control the speed in a short time.In cement production, cement ball mill into production, its breakdown of the number of cement particles and cement products taste directly linked to the size of ball speed.Well, that is, as long as improve their speed and the speed control system through the material out of a difference in their level of production or output to maintain a constant speed changes can greatly status companies to create more profits. However, because there are some reverse gear torque limit, can not indefinitely increase the speed of ball mill, after reaching a certain level, if that deliberately continue to increase speed, often driven gear coil mill burned, resulting in equipmentdiscontinued, the general maintenance cycle mill in 1-2 weeks.Such consequences are no different from a serious economic consequences for enterprises. 

Correct operation of the cement ball mill method
1.planetary ball mill gear dust cover must be tight to prevent dust, sand intrusion.

2.if found with the main gear bearing sediment may or invasive treatment should be immediately stopped and cleared, and definitely not delay.

3.the planetary ball mill large tile heating, the occurrence of an accident or near Burnt Burnt should take immediate measures for forced cooling may not be immediately stopped, to avoid causing “axle” vicious accident.

4.must be strictly enforced to the mining, water supply, add the ball of the provision prohibiting overload, attention to prevent “belly up” phenomenon, while to the amount of ore is not too small.Also not allowed to load Operation, avoid to damage the liner.

5.fixed ball screws should be added hemp liner ring seal to prevent leakage, leakage of slurry.

6.the gap between the liner for the 10-20mm for the replacement (available when oxygen welding cutting too tight).

7.the planetary ball mill no more than two consecutive start, the first and second should be an interval of 5 minutes.Starting the third time must be approved by electricians, fitters with the examination before starting.

8.the same workshop with several ball shall not also start two synchronized machine.
