Applied materials: quartz, iron ore, copper ore, gold ore, glass, construction waste, cement clinker, etc. in the industrial production such as refractory materials, chemical industry, metallurgy, glass, sand industry and others.
Rod mills are very similar to ball mills except for the use of steel rods as grinding media. In the rod mill, steel rods grind the ore by rolling and rotating. The feeding of rod mill is 50 mm, and its output particle size is -4 to 35 mesh.
If the rod mill is used for the first stage grinding equipment to grind materials from 20~6 mm to 3~1 mm in the two-stage grinding process, the production capacity will be larger and the efficiency will be higher.
In some cases, it can replace the short-head cone crusher for fine crushing. When processing soft ores (especially viscous ores) from 19-25 mm (or even 32 mm) to 6-10 mesh, using rod mills is simpler and cheaper than a closed circuit formed by the short-head cone crusher and the sieve.
For hard ores, it may be more economical to use a short-head cone crusher and a sieve to form a closed circuit. Whether to choose a ball mill or a rod mill must be determined according to the specific conditions.
The rods have a screening effect on the materials during movement, which can make the large particle material be lifted to the high position of each layer and concentrated to the place with strong crushing ability. Therefore, the working efficiency of the rod mill is high and the power consumption is low.
When the rod rotates and rises along with the liner, the coarse particles are sandwiched between them, allowing the fine particles to pass through the gap of rods, which is conducive to crushing coarse particles, so the coarse particles are concentrated in the place where the grinding medium hits.
The particle size of the material produced by the rod mill can be adjusted according to the needs of users, because there are a fineness control device and a screening device for discharging inside the rod mill. These two devices work at the same time.
The feeding device is a shoe-shaped hopper, and the upper flange is connected with the feeding equipment to receive the fed material. There is an inspection door on the back wall of the hopper, forming a round tube and extending into the spiral barrel mounted on the hollow shaft, through which the material enters the mill.
The rotating part is a cylinder rolled and welded by steel plates. A liner is arranged inside the cylinder, which not only protects the cylinder but also lifts the steel rod to a suitable height to improve the efficiency of sand making. There is an acid and alkali resistant rubber pad between the steel liner and the simplified end cover to reduce noise and vibration.
The large and small gears are driven by helical gears with balanced work, small impact and long life. It adopts spray lubrication and regular oil injection, which reduces the labor intensity of workers, has a good lubrication effect and reduces the consumption of lubricating oil.
The main bearing supports all the weight of the rotating part, steel bars, materials, etc. The bearing bush is supported on the spherical seat, which can play a self-defense function to adapt to manufacturing and installation errors.
After the long-term work of the main bearing, the bearing bush will wear and tear, resulting in the sinking of the hollow shaft. The sealing bracket can be adjusted downward to ensure that the seals and the hollow shaft are in good contact.
Rod mill makes tube run with the help of the reduction gears drove by dynamo or the low-speed synchronization electrical machine. There are steel rods in the tube which are thrown at a certain high speed by centrifugal and friction force and then fall.
The ground material enters into the tube continuously and is crushed by the moving steel balls. After that, they are discharged from the machine naturally and will start the following working process next.

Jaw crusher is mainly used for the medium-granularity crushing of all kinds of ores and large materials in mine, metallurgy, building material, highway, railway, water conservancy and chemistry. The maximum compression strength of the materials to be crushed is 320MPa.
The Advantages and Benefits of Jaw Crusher: Jaw crusher is a crushing machine that is researched and developed very early. With simple and solid structure, reliable work, easy maintenance and repair and low production and construction fees, it has long been widely used for the coarse, medium and fine crushing of various kinds of ores and rocks whose compression strength is 147~245MPa in many industrial departments such as metallurgy, chemistry, building material, power plant and transportation.
2. More advanced movable jaw assembly makes it more durable. The movable jaw assembly uses high-quality steel casting and drives through two large-sized cast steel flywheels. In addition, the heavy eccentric shaft also adopts forging stock which makes JC series jaw crusher have extraordinary reliability.
3. The bearing pedestal adopts unitary cast steel structure. The unitary cast steel bearing pedestal can ensure comprehensive fitting with the crusher rack, and at the same time, greatly increase the radial strength of the bearing pedestal, whereas split type bearing pedestal does not have these advantages.
Rhyolite is igneous, which belongs to volcanic ejectedrock, its chemical composition is the same as granite, due to the cooling of minerals formation is too fast, it cannot form crystallization, silica content greater than 69%, which is mainly made up of K-feldspar and quartz. The rocks are gray, pink or brick red, porphyritic structure and rhyolitestructure. In China, mainly exist in the southeast coastal areas. Because chemical composition isthe same as granite, it means include at least one kind of granite. Granite is most likely to be generated by the magma, and the phenocrysts of rhyolite may include quartz, alkali feldspar, Austria feldspar, amphibole or pyroxene.
