The ore mined is first brought to jaw crusher for preliminary breaking, and after broken to reasonable fineness evenly taken into ball mill by hoist and vibrating feeder for crushing and grinding. The fine ore stuff grinded by the ball mill enters into the next process: classification. The spiral classifier uses the principle that solid particles of different proportion have different settling velocity in liquid to cleanse and classify the ore mixture. When the cleansed and classified ore mixture passing the magnetic separator, the magnetic materials contained in the mixture will be separated by magnetic force and mechanical force due to their different specific magnetization coefficient. And then the mineral particles that are preliminarily separated by the magnetic separator are sent to the flotation machine and mixed with different chemicals according to the characteristics of different minerals contained to separate the targeted minerals from other materials. After the targeted minerals are separated, as they carry a lot of moisture, they must be preliminarily enriched by the thickener and dried by the drier and then dry minerals can be got.
The mian method of molybdenum ore beneficiation is flotation. The recovery molybdenum is molybdenite. Sometimes in order to improve quality of molybdenum concentrate and to remove impurities, molybdenum concentrate is dealt by chemical beneficiation once again. Molybdenite crystals has six-layered or plate-type structure which is formed by paradigm of health along the inter-layer s-mo-s structure and the layer of polar covalent bond s-mo. The binding among layers is weak, but covalent bond binding inner the layer is strong. So molybdenite is easy solution fissure along structural layer to show sheet or plate. This is the reason that digenite has well floatability in nature. Practice has proved that with suitable grinding fineness, molybdenite crystals dissociat in s-mo-s layer and the hydrophilic s-mo takes up little area. But through mill, the area ratio increases, and floatability reduces. Although at this time to add some quantity of polarity collector such as xanthate, which is benefit for the recovery of molybdenite, new slime, caused during mill, affects flotation results. So molybdenite of sorting should avoid and prevent grinding. In the production, we should take the process of sub-ore grinding and multi-stage sorting to achieve monomer dissociation and to make sure high recovery rate of molybdenum.

PF Series Impact Crusher use impact energy to crush materials. When the impact crusher works, the motor drives the rotor of the impact crusher rotate with a high speed. When the materials get into the area which the hammers effect, under the impact function of the hammer at a high speed, materials are thrown to the impact device above the rotor continuously. And then the materials are rebounded from the impact liner to the area where the hammers effects for recrushing, then discharged from the discharge port. Users can adjust the space between Impact Rack and Rotor Support to get the expected size.
Feature and Advantage: SMH Series Hydraulic Cone Crusher possesses greater superiority than ordinary ones. 1.

Appliance: Vertical impact crusher is also known as sand making machine is applied widely for the powder process of mineral product including mental and non-metal ore, fireproof material, bauxite, diamond dust, glass raw materials, architectural materials, artificial sand and all kinds of metal ore materials, especially which has more advantages than any other machines in processing the more and most hard materials. Features and Benefits: 1.High efficiency and low consumption 2.Primary and second crushing capacity 3.More and most hard materials can be crushed4.Cubic shaped final product 5.Little noise and dust pollution 6.Convenient performance, maintenance, installation7.Simple structure, low production cost. Working Principle: Vertical impact crusher includes hopper, classifier, whirl pool cavity, impeller, main bearing assembly base, transmission device and motor etc. Operating principle is as follows: the materials enter the crusher through feeder hopper, which is divided into two parts, one part through the middle of classifier entering into the rotating impeller at high speed, then accelerated, whose speed can reach hundreds of acceleration, then is shot through the tunnels around the impeller by the speed of 60-75 meter/second. First the materials will impact with some materials fallen around classifier, then impact on the whirlpool cavity scale board together, then will be rebounded and impact on the top of the whirlpool cavity, then changes its direction and goes down, forms continual material layers with the materials shot from the impeller. Therefore some materials will be impacted, crusher, milled twice or more times in the whirlpool cavity, then crushed materials will be excluded through the bottom discharging hole. This can from a closed circulation through the circular classifier system; in general, materials can be crushed into 20 mesh through thrice circulation. Airflow self-circulation in the whirlpool cavity can eliminate the dust pollution well.

Description: Ring hammer crusher is a punching rotor type crushing machine with ring-hammer on the rotor. The material is firstly crushed by the punching force of the high speed ring-hammer rotating, then the crushed material is thrown forward to crushing board for the second crushing, required sizes material will get out through the sieve plate, but bigger sizes material will be shot back to the ring-hammer again for the third crush. Such process repeats until the materials are crushed to the required size. Applied scope: ring hammer crusher is suitable for many departments, such as mine, cement, coal, metallurgy, building material, highway, burning material and so on. The solid material with medium hardness brittle material¡¡¥s fine crushing is available from ring hammer crusher. Besides, ring hammer crusher can be used widely to meet customers different requirement of different product size by adjusting the gap between grates. Characteristics: The characteristics of simple structure, easy maintance make ring hammer crusher sell abroad, and be appreciated by
Application: Impact crusher can deal with any large, middle, and small materials(granite, limestone, concrete, etc.) with length no longer than 500mm, and compressive strength less than 350mpa. It is widely used in mining, highway, railway, and construction industries to produce artificial sandstone materials. At present, the comprehensive capacity of impact crusher is prior to cone crusher and hammer crusher. Working principles: impact crusher is a kind of crushing equipment which uses impact energy to crush maters. When getting into the effective area of hammer plates, due to the high speed of striking, the raw materials are thrown onto the impact equipment which is installed above the rotor. Then the materials are rebounded to the effective area of hammer plates and crushed again in the crushing chamber. At last, when the particles reach to the proper size, they will be discharged from the bottom of the machine. Main features: impact crusher has the characteristics of novel structure, no-bond connecting, high chrome plate hammer, special impact lining plate and energy saving. The finished product is in cubical shape and the discharge granularities can be adjusted. It simplifies the crushing process. They have the advantage of greater reduction ratio and the final materials are in cubical shape and even.
Jaw crusher is crushing stone equipment with long history. It is widely used in metallurgy, mechanical industry, building material, power, transportation until now, because it is simple in structure, b, reliable, easy for maintenance and repair, and with low cost. It can crush rocks with strength of 147-245mpa. As everybody knows, the main disadvantage of jaw crusher is that lifetime of jaw plates is short. In order to solve this problem, our company has developed special material for it. Also fluid coupling is used in large model jaw crusher to improve start process, and avoid overload.
Pe and pex series jaw crusher crust take high strength steel plate through processing of welding and heating and finally become stronger and tougher.
