The rod mills have milling and grinding in the friction forces of the rods together with the vibration.
Our mills are designed according to processes to make wet and dry system.
The necessary factors to determine the mill size, preservation grain size, product grain size, ore properties, available options and option processing concept.
Ï?40-120mm, Length 2-6m ( HRC45-55) The grinding rod has high hardness(45-55HRC),low wear friction,strong toughness,The wear-resistant effect is 1.5 to 2 times the raw steel rod,after refining,the internal stress was relieved.So the rods are perfectly straight and not break,,Two head not nozzle, and with good wear resistance.
Grinding steel rods-grinding bar with proper heat treatment Diameter: 80mm-140mm Length: As per customer's request Hardness: HRC45-55 Application: Various rod mills for metal mines The grinding rods are produced by alloy steel materials, which have got the national patent. We have one complete strict quality control systems from the materials, production process and finished products to ensure the steady quality of the grinding rods. Should you have any interest, please feel free to contact us.
The rod mill is decelerated and driven by the motor through the reducer and the surrounding large gear, or by the low-speed synchronous motor directly through the surrounding large gear to drive the cylinder to rotate. The cylinder body is equipped with appropriate grinding medium - steel rod. Under the action of centrifugal force and friction, the grinding medium is lifted to a certain height and falls in a throwing or discharging state. The ground material continuously enters the cylinder from the ore feeding port, is crushed by the moving grinding medium, and the product is discharged out of the machine through overflow and continuous ore feeding to carry out the next process [2]. When 80% of the product particle size is required to be less than 2.0% to 0.5mm, the rod mill is generally used. The product particle size of the rod mill is generally no more than 4.7MM and no less than 0.4mm. The ore feeding particle size of the rod mill is 80%, less than 20mm to 4mm, and the maximum ore feeding particle size can also be up to 50mm. Due to the material of the grinding rod and other reasons, the length of the grinding rod shall not exceed 6.1m, otherwise it will cause bad consequences such as disorderly rods. Therefore, the specification of the rod unloader has not exceeded specification 4.6 Ã?? 6.3m. When the ore is fed into the rod mill, the coarse particles are at the feeding end and the fine particles are at the discharge end: therefore, the rod group cannot be completely parallel and inclined during operation, which is also a reason why the grinding rod cannot be too long.

Our company is Used Wire Rod Millfixing and revising a set of 135 m/s #High-speed #Wire #Rod #Mill equipment, annual output 30,0000 tons. Which including 350, 450mm intermediate rolling mill unit, 350, 450mm intermediate gearbox, one horizontal pre-finishing rolling mill, one vertical pre-finishing rolling mill, 10 stands finishing rolling mill units, laying head, pinch roll, and Sund Birsta packer. Because of the environmental problem, the government forced to close the whole line. The production of this set of units in Xian is less than 20, 000 tons, almost new. After the maintenance of our company, the machine unit can be completely new.
Grinding steel rods with heat treament Diameter: 50mm-140mm Length: As per customer's request Hardness: HRC45-55 Application: Various rod mills for metal mines Grinding rods made by Shandong Huamin are a type of grinding media used in mineral processing industries such as mining, cement, and power plants. These rods are cylindrical in shape and made of high-quality steel that is forged and heat-treated to ensure optimal hardness and wear resistance. Shandong Huamin uses advanced production technology and quality control measures to ensure that their grinding rods meet the highest standards of quality and performance. The rods are designed to provide maximum impact resistance and long service life, even under the most challenging operating conditions. Grinding rods made by Shandong Huamin are available in a variety of sizes and lengths to suit different grinding applications. They are typically used in rod mills, where they are used to grind ore by tumbling it in the mill. The grinding rods work by repeatedly impacting and grinding the ore particles, breaking them down into smaller sizes until they are fine enough to pass through the mill's discharge grate. Overall, Shandong Huamin's grinding rods are a high-quality and reliable grinding media option for mineral processing operations.
Swivel type lead-bronze bushed trunnion bearings are generally furnished on large diameter ball Mills. The bearing swivels are of Meehanite metal spherically turned outside and bored and faced inside to receive the removable bushing. The bushing is bored and scraped to fit the mill trunnion. The bushing is provided with end flanges thus assuring that the trunnion flanges run against a bronze face. On smaller mills rigid or swivel type bearings support the mill trunnions. The lower half of such bearings are lined with bronze or a special mill babbitt which is peened in place and bored to fit the trunnion. In all cases a low bearing pressure is maintained to assure freedom from overheating, long life and minimum maintenance. They are designed to provide support to the mill proper, its media and pulp load. Trunnion bearings are generally supplied with seals for use with a circulating oil lubrication system. They can be designed to accommodate block grease or oil with wool waste. For special applications trunnion bushings can be furnished constructed of Micarta to allow water lubrication or oil lubrication. In many dry grinding applications, or where heat is developed, the trunnion bearings can be furnished for water cooling. This system carries away the excess heat transmitted through bearings and protects them.
