The main component of wet overflow ball mill is a cylinder with bigger diameter and smaller length which is revolved by transmitting machinery. Materials are put in cylinder through the feed opening and then thoroughly grinded. The falling course of iron balls and ores can produce huge falling impact and autogenous grinding

May 18, 2020 The overflow ball mill discharges the ore by the gravity flow with the slow speed, so its production capacity is relatively weak, and because the material stays in the ball mill for a long time, it is easy to cause the over-grinding phenomenon. 3. According to the grinding effect

Overflow Ball Mill Overflow ball mill is a kind of mineral processing ball mill. Its name comes from its discharge mode. The discharge mode of the overflow ball mill is non forced discharge. Only when the pressure in the cylinder reaches a certain degree, and the slurry is higher than the lower edge of the hollow shaft at the discharge end will

Oct 19, 2015 Overflow ball mills are the most commonly used mill in the grinding stage for a processing plant.Double rolling bears are adopted in overflow ball mill instead of sliding bears, which will reduce the friction during grinding work and solve the problem of tear and hard turn on

Aug 19, 2021 The work index of the material is 13kW-h/t, and the universal hardness is f=8~12; the working condition of the overflow ball mill is continuously feeding. 1.2 Energy consumption index Under the specified standard working conditions, the ratio of the measured power to the processing capacity of the overflow ball mill is expressed in kW-h/t

Overflow ball mill i s is composed of feeding part, discharging part, turning part and driving part (reducer, small driving gear, electric motor and electric control). The quill shaft adopts cast steel part and the liner is detachable. The turning gearwheel adopts casting hobbing process and the drum is equipped with wear-resistant liner, which has good wear-resistance

Kunming Ciba Mining Machinery Co., Ltd. is involved in designing and manufacturing wet-grinding grate-discharge and overflow-discharge ball mills, and wet-grinding overflow-discharge rod mill which own multiple patents. The advantages of such equipment includes properly designed feed opening, cylindrical section made of high-strength steel

Nov 14, 2014 Ball mills are the main machines in the grinding process. Mineral processing experts will choose different ball mills according to the different properties of ores, such as particle size, capacity. Ball mills are divided into wet ball mill and dry ball mill, overflow ball mill and grid ball mill

Aug 29, 2013 Metso Overflow Ball Mill sizes range from 5 ft. x 8 ft. with 75 HP to 26 ft. x 41 ft. with 20,000 HP. Larger ball mills are available with

Overview of overflow ball mill. According to different ways of ore discharging, ball mill is divided into grate ball mill and overflow ball mill, which is currently the most common ore grinding machine. Overflow ball mill is the key equipment for grinding after the crushing process, and it is widely used in the manufacture industries such as cement, silicate, new building

Feb 13, 2017 Overflow Ball Mill: Suitable for almost all applications where a ball mill is required. Simple and trouble-free grinding method. The discharge trunnion can be furnished with trommel screen. Grate Discharge Ball Mill: This type of mill usually works with a high circulating load and thus produces very little extreme fines. The specific power consumption is therefore less than

Jun 24, 2015 Allow me to compare: Ball mills can be of the overflow or of the grate discharge type. Overflow discharge mills are used when a product with high specific surface is wanted, without any respect to the particle size distribution curve. Overflow discharge mills give a final product in an open circuit

Overflow ball mill is a kind of ball grinding mill which works in wet water state. It belongs to a type of wet ball mill and is a very common grinding equipment in the concentrator. Ball grinding mills are classified according to the discharge methods

The overflow ball mill can be used for primary grinding or re-grinding for the expected particle size.
