There are numerous kinds of Red Star stone crushers. According to different crushing methods, Red Star stone crushers include hammer crusher,  and roller crusher. In terms of particle size of finished products, stone crushers fall into coarse crusher and fine crusher.
Red Star high efficiency stone crushing equipment is reliable in operation and smooth in performance, simplified processing flow, simple crusher structure, convenient maintenance, large production capacity and long service life of hammer head. They are perfectly suitable for making grinding material, refractories, cement, quartz sand, steel grit, etc. That without doubt is a kind of high efficiency, energy saving stone crushing and sand making equipment, which can save energy by 50% than traditional stone crushers. So far, Red Star crushers are the most advanced stone crushing equipment.

Stone crushing production equipment use processing flow:
The hammer crusher (hammer mill) crushes by the collisions between high-speed hammer and material, and the hammer crusher (hammer mill) has the features of simple structure, high reduction ratio, high efficiency, etc.

Red Star mining company ore dressing factory used stage wet type mill mine magnetic selected technology. As for lower grade of rough fine mine, we used two sets one stage ball mill and one set two-paragraph ball mill, forming of "Two Vs one" grinding mine process. After grinding and wet type magnetic selection, the ore grade above 25% of rough mine will eventually be processed into iron fine mine grade above 66. 0%, whose production cost is less than 200/t concentrates. Beijing Technology University did beneficiation technology experimental study on super lean magnetite ore in Hebei province. Study finds that rough ore is grinded to 2mm, which will abandon 75. 66% qualified tailings after wet pre-selection. In this way, only one-fourth of the original ore reserves for subsequent processing work, so that it greatly reduces the subsequent operational load. Rough milling adopts cylinder sieve and grinding machine, and the two constitute a closed circuit, mill productive capacity improved by 2.9~3.8 times. And the grinding unit energy consumption greatly reduced.

When gangue mineral disseminated is relatively fine granularity, ore can be broken into smaller ones, and we use wet magnetic separation treating tail. Red Star mining company did research to ore, many study results demonstrate that, coarse ore (refer to over 10 mm size) pre-selection parabolic tail effect is extremely poor, It only treats 1O% tailings when using dry magnetic separation, the grade is less 2%. Moreover, magnetic iron loss rate is more than 3%. Thereby, dry magnetic separation only to treat coarse parabolic tail cannot eventually solve the problem. In 2004, Sinosteel mining Institute and Germany KHD Humboldt ? weida did semi-industrial test of high pressure roller mill and roller mill products sorting test. In that study, they treated 3.0 mm ore with grade of 26.27% by using magnetic roller mill pre-selection. It can cast in advance qualified tailings with output rate 47. 80%, grade 8 310/e. The research created a new situation for domestic ultra lean iron ore utilize. To achieved ore pre-selection throwing tail, significantly improve ore grinding grade as well as upgrade ore processing capacity, reduce mill selection cost, Red Star mining company has made a breakthrough progress. After in-depth exploration and repeatedly tests and research, they used high pressure roller mill machine and line Shaker, and the two form a closed circuit broken system. It will be able to crush 20.0 mm ore to 3.0 mm, and then the tailing selection will be treated with wet midfielder strong magnetic selected machine. Thus rough fine mine grinded again and finally get grade 65.00% of iron ore concentrate.

Gravity separating equipment is of significance to ore concentration plant

In recent years, the successful development of weak magnetic gravity separation equipment, such as magnetic separation column, composite Flash and magnetic field screening separator machine, will be described in this paragraph. Beijing General Research Institute of mining and metallurgy researched BK series permanent magnet drum magnetic separator, including BKY, BKC, BKJ, BKW, and BKF 5 models, which respectively apply to the pre-selection, roughing, premium, flotation tailings re-election and anti-bubbles of magnetic separation. They gain a good technological specification, and play an important role in increasing yield and economic benefit for magnetic separation plant. In recent years, the successful development of the largest specification CTB-φ 1 200 mm X4 500 mm wet permanent cylinder type magnetic separator, the magnetic angle is 127 degrees, magnetic induction in sorting area tube sheet is 180-350 mT, dealing capacity is up to 200-320 t/h (mine), pulp processing capacity is 600-700m3/h.

Measurements and tolerances play an important role in most of the bearings whether it is angular contact bearings or clutch bearings. Most exporters or manufacturers have achieved world-renowned positions by going beyond 100% of measurements, stubborn commitments and consistent results to the customers who are always satisfied. This positions are not achieved in just some time or few years but takes long years of highly technical accumulation that includes experience of a to z of bearings. If you are in search of such bearings they are specified by a standard numbering system by it's industry or people. Indian manufacturers are also world-renowned with having over 30 years of experience in manufacturing of such bearings.
Cone crusher is the aggregate crushers that are most often employed in large mining or quarrying operations. A jaw crusher is designed to crush large pieces of ore or rock between two plates or jaws. One jaw is stationary, and the other is mounted so that the two jaws form a V-shape. The second jaw moves back and forth relative to the first jaw, crushing the material as it moves downward, until the pieces are small enough to fall through the opening at the point of the V. Multiple aggregate crushers of the jaw type are often employed in a series, gradually reducing the particle size.

Bearing are world-famous and its types counts too many. They are address different functions and performance with abilities to cater various applications. Bearings exporters manufacture or trade these bearings to all around the globe for various uses. You can find bearings into many things from automobiles to skates. They are meant to support various loads and they could be in various forms. Bearings you find commonly are ball bearings, clutch bearings, angular contact bearings, clutch bearings, tapered roller bearings and many more.

Angular contact bearings are meant to perform for radial and axial loading where its different designs and components used supports low to high axial loads. If these angular contact bearings are designed in specific to take high loads then the cages, lubricants, balls etc are expanded and specially designed. They function is high-speed and are used in precision applications including general industry, agriculture, utilities etc.
