It is also used in chemical industry and petroleum sectors. It is gray or black and the hardness is 5-5. It has weak magnetism.0-5. It can be used in aircraft, rockets, missiles, ships and so on. Belongs to the fragile material, its relative density is 4.Ilmenite is iron and titanium oxide mineral and it is the main refining titanium ore.5.

Stone crushing is generally operated in three stages: primary crushing, secondary crushing and tertiary crushing stage. The unrequired size will be returned by belt conveyer for re-crushing, The crushing and size reduction plants include PEW jaw crusher, PFW impact crusher, cone crusher, hammer crusher, mobile crusher etc.It is important to arrange an efftive quarry crushing production line, which will save investment cost and optimize profits. Between each crushing stage, there is vibrating screen to sieving the crushed materials. Crushing is the initial stage in the stone production line.

Ball mill is the most common used mineral grinding machine and the ball mill will work together with the mineral ore crushing machine and the beneficiation machine to reduce the size of the material. Now, the small scale ball mill is widely used both the dry and wet grinding department like the cement, portland products, new building material, refractory material, fertilizer. Most of these ball mills has high efficiency and can process the material into extremely fine powder. Recently, the small scale ball mill is very common to see on the mining production lines.

Many modern rock quarries also make aggregates, or small pieces of rock that are used in a variety of construction projects, by crushing large rocks into small pieces.Rock quarry is an open pit mine where various types of rocks are extracted from the earth for a variety of purposes. Most modern rock quarries strip the soil or mountain side to get to the hard rock underneath. With each subsequent bench, the mine becomes deeper in the center, with stepped benches reaching up to the surface. The hard rock is then broken off in a "bench" pattern, meaning it is broken off in layers that can be returned to year after year for more quarrying.

Without being bound by theory, it is believed that in addition to impact control by the grinding aid, the interaction between delocalized π-electrons of the grinding aid molecules and the freshly exposed surfaces of the graphene nanoplatelets stabilize the graphene layers, and the hydrophobic nature thereof repels oxygen and thus protects from the oxidation, amorphyzation and reagglomeration .
