Continuous ball mill refers to the continuous production of material processing process.Both feed in and feed out materials process are carried out in a row, which could adopt open or closed circuit production. By open circuit production process,it has a large production capacity, and there is no need to control the product size strictly. But the closed-circuit grinding to regrind the material that is non-stardard finished product size by the regrinding device. Continuous ball mill is widely used in different industries.

In the continuous type ball mill, the material is being fed from the one end through its hollow shaft, while the crushed material comes out from the hollow shaft, at the other end. Usually continuous Mills are used when the production rate is required to be high.

grinding cylpebs

grinding cylpebs

Our automatic production line for the grinding cylpebs is the unique. With stable quality, high production efficiency, high hardness, wear-resistant, the volumetric hardness of the grinding cylpebs is between 60-63HRC,the breakage is less than 0.5%. The organization of the grinding cylpebs is compact, the hardness is constant from the inner to the surface. Now has extensively used in the cement industry, the wear rate is about 30g-60g per Ton cement.

Grinding Cylpebs are made from low-alloy chilled cast iron. The molten metal leaves the furnace at approximately 1500 C and is transferred to a continuous casting machine where the selected size Cylpebs are created; by changing the moulds the full range of cylindrical media can be manufactured via one simple process. The Cylpebs are demoulded while still red hot and placed in a cooling section for several hours to relieve internal stress. Solidification takes place in seconds and is formed from the external surface inward to the centre of the media. It has been claimed that this manufacturing process contributes to the cost effectiveness of the media, by being more efficient and requiring less energy than the conventional forging method.

Because of their cylindrical geometry, Cylpebs have greater surface area and higher bulk density compared with balls of similar mass and size. Cylpebs of equal diameter and length have 14.5% greater surface area than balls of the same mass, and 9% higher bulk density than steel balls, or 12% higher than cast balls. As a result, for a given charge volume, about 25% more grinding media surface area is available for size reduction when charged with Cylpebs, but the mill would also draw more power.

Dry Grinding Attritors can be operated in Continuous or Batch operation. For a complete explanation of how Dry Grinding Attritors work in both Continuous and/or Batch operation, please download the Technical Paper Attrition Dry Milling in Continuous and Batch Modes.

The SD Dry Grinding Attritors can be operated in both continuous and batch processing applications. In the continuous operation, the material is fed into the vessel at the top. It then migrates through the agitating media bed where it is processed to a desired particle size and is discharged through metering bar grids at the bottom of the tank.

In the batch mode, material is charged into the mill at the top, ground for a predetermined time, then discharged through grids at the bottom. The system can easily be sealed for grinding under inert gases such as nitrogen or argon.

The SD Attritor is also used to make dispersion-strengthened metal (DSM). In this process (known as mechanical alloying or cold welding), the kinematic porosity results in the grinding media breaking the metals into small particles and beating them together to form agglomerates. By repeating the process, the various metals are evenly mixed and dispersed to form a new composition of alloy (DSM).

Union Process SD Dry Grind Attritors are ruggedly built machines with specially designed, two-speed, high starting torque motors. They are also equipped with jacketed, stainless steel tanks and tilting mechanisms for ease of cleaning and maintenance.

heat treatment process for high chromium grinding ball

heat treatment process for high chromium grinding ball

Ball mill is widely used in building materials, mineral processing, cement, thermal power generation and fertilizer production of the main grinding equipment, grinding ball is the largest consumption of wear-resistant parts. Therefore, with the continuous development of key industries such as building materials, the demand for grinding balls will increase greatly. At present, ordinary forged steel balls are mainly used, with an average consumption of one kilogram of steel balls per ton of cement, and about two kilograms of steel balls per ton of metal ore ground This was nearly ten times more relevant than at the time. Especially as the third generation of anti-wear Alloy High Chromium White cast iron developed successfully, so that more than 4.5 m of large-scale cement mill ball consumption to 30 ~ 50 G / T, medium and small-scale cement mill ball consumption also reduced to only 100 G / T or so The new material revolution has greatly improved productivity and economic returns. It was only in the mid-1970s that I began my research on the development of cr-based white cast iron. The Xian Jiaotong University of Mn-Cr-Cu-Mo series and high-cr-based wear-resistant white cast iron were selected and developed. Since the 1980s, a variety of new wear-resistant materials developed in China have been gradually applied to the actual abrasive wear operations, some of which have reached the level of similar products abroad.

The good wear resistance of high chromium cast iron mainly depends on its matrix structure and the type and distribution of carbides. High Chromium cast iron is a kind of chromium white cast iron with chromium content between 12% -28%. This alloy of carbon and hard compounds gives high chromium cast iron good wear resistance. On the other hand, during solidification, M7C3 type carbides distribute in a rod-like shape, which can improve the toughness of high chromium cast iron to some extent. The production of high chromium cast ball is mainly composed of casting and heat treatment. Casting is mainly composition design, the casting method, carbide, and matrix structure directly, affect the wear resistance and toughness. Carbides and Metal Matrix Organization is first, by its chemical composition, so must be the reasonable design of its chemical element, content, followed by the heat treatment process

As mentioned before, high chromium grinding ball has excellent wear resistance in abrasive wear and has been widely used in many industries of national economy This is mainly because the high-chromium cast ball can obtain strong and tough matrix structure and high hardness M7C3 carbide by proper heat treatment and alloy modification. Many units at home and abroad began to choose high-chromium cast ball as a cement, mining, electricity and other industries as Abrasives, so high-chromium cast ball production technology has been the main topic of study at home and abroad.

Heat treatment of high chromium grinding ball is the main method to obtain good wear resistance. The research on high chromium cast iron ball mainly focuses on chemical composition selection, heat treatment process determination, modifier selection, good carbide type and wear mechanism. Foreign foundry researchers are more committed to the high-chromium cast iron microstructure, wear-resistant mechanism, and new preparation process development. Here are the specifications for the High Chromium Grinding Ball:

From the above indexes, it can be seen that the hardness of the grinding ball before and after quenching is quite different. The heat treatment process of high chromium cast iron grinding ball includes wind quenching, oil quenching, and special quenching solution treatment. After repeated test and mining, the oil quenching can fully meet all its technical specifications The consumption of iron ore is twice that of iron ore. The heat treatment process is the use of two-stage heat quenching and low-temperature tempering. At the rate of less than 70 C / h, the temperature is increased to 650-680 C for 2 hours, at the temperature increasing to 950 C for 4 hours, forced air-cooling, oil-cooling, and special quenching liquid cooling respectively, and tempering is carried out at 200 C or 420 C According to the ball diameter was 4 hours, 6 hours, 7 hours, out of slow cooling.

After reasonable matching of all elements, ratio casting qualified grinding ball blank, adopt continuous heat treatment furnace to ensure the uniformity of furnace temperature, select the appropriate quenching medium and tooling, the equipment to ensure the consistency of the process, to ensure the stability of product quality. Problems such as low wear resistance of high chromium grinding balls, high rate of breakage and large roundness loss were solved.
