The size of the ball mainly depends on the particle size of the material to be ground, and the diameter and speed of the mill can be considered appropriately. Formula (1-15) is an empirical formula for spherical diameter and feed size. dmax — The maximum diameter of steel ball, mm; amax — the maximum size of feeding granularity, mm.
Comparing to the widely applied ball milling, the second law efficiency is 16.4% higher for the VRM than the ball mill. Results also showed when the classifier rotor speed increases from 53 to 65 rpm, the particle size of the product decreases from P 90µm = 18.2% to P 90µm = 10.8%, but the power consumption of the VRM unit increases from …
The efficiency of fine grinding in the second compartment is largely controlled by the size of grinding balls. Due to limitation of the mill's rotational speed, the smallest ball size is usually restricted to about 15 mm. Cement grinding using stirred mills (Pilevneli and Azizli, 1999) indicates that using smaller media (5–8 mm range ...

Widely used in cement plants, power plants, etc. High and low chromium multi-element alloy steel balls, cast and forged high and low chromium multi-element alloys. The ball mill is the key equipment for the material to be crushed and crushed again. Ball mill is one of the high-fine grinding machines widely used in industrial production.
An increase in the diameter of a mill gives greater economy in two ways : In the first place, the balls do more effective work in a large than in a small mill, because, falling from a greater height, they shatter the pieces of ore with greater force ; in the second place, the ratio of the deadweight of the mill to the weight of the ball charge …
Cement ball mill and vertical roller mill are two most widely used cement mills in today's cement grinding plants and are also the main types of cement mill we produce. As a professional cement equipment manufacturer, AGICO has rich experience in the designing and manufacturing of cement ball mills and vertical roller mills.
The vertical roller mill is less power consuming. The energy consumption of a vertical roller mill is around 75% of that of a ball mill of the same capacity. Vertical roller mills can be transported in parts and constructed onsite, avoiding difficult logistical issues and associated costs. The fineness of product cement can be adjusted easily ...

The proven classical option for cement grinding. Whether employed as a two-compartment separator mill in an independent grinding system, or in combination with a high pressure grinding roll, the Ball Mill is a robust and reliable alternative for cement and granulated blast furnace slag grinding.
We provide ball mill machine for cement plant, power plant, mining industry, metallurgy industry, etc. Ball mill machine can grind a wide range of materials, with enough continuous production capacity, simple …
Ball Mill. Ball mills with high efficiency separators have been used for cement grinding in cement plants all these years. Ball mill is a cylinder rotating at about 70-80% of critical speed on two trunnions in white metal bearings or …
What are the dimensions of the ball mill you are looking at? 40% ball charge is quite high (unless you are looking at a small mill). A difference (duty vs. maximum) of 5% to 10% is fairly typical and you would likely struggle to perceive an energy efficiency difference between the two operating points. Beyond this, the situation may change.

The cement ball mill is a kind of cement grinding mill. It is mainly used for grinding the clinker and raw materials of the cement plant, and also for grinding various ores in metallurgical, chemical, and electric power enterprises.
Inside, at 1400 degrees C, the raw material is transformed into clinker: small, dark gray nodules 3-4 centimeters in diameter. 9. Cement milling The clinker is ground by different-size steel balls while it works its way through the mill's two chambers, with gypsum being added to extend cement setting times. 10. Cement packaging and shipping
Forged Steel Balls are used for gold mining, cement factories, oil processing and large scale industrial applications. They are made by machine (standard) sizes 20mm–75mm. They are manually made (hit by air hammer) sizes 75mm–125mm. They have hardness 55–63 HRC. All forged balls are through-hardened, and shipped in 55-gallon steel drums.

Operation and Elements of a Closed Circuit Ball Mill System Cement ball mills typically have two grinding chambers. The first chamber is filled with larger diameter grinding media and lined with lifting liners. The first chamber coarse-grinds the feed material and prepares it for the second chamber. The second chamber is the fine grinding chamber.
Steel balls are one of the most widely used grinding media in cement ball mills, their diameters can range from 20mm to 150mm according to different grinding requirements. In a cement ball mill, generally, φ50-100mm steel balls are used in the coarse grinding chamber, φ20-50mm steel balls are used in the fine grinding chamber. 2. Short Cylinders.
