The basic parameters used in ball mill design (power calculations), rod mill or any tumbling mill sizing are; material to be ground, characteristics, Bond Work Index, bulk density, specific density, desired mill tonnage capacity DTPH, operating % solids or pulp density, feed size as F80 and maximum 'chunk size', product size as P80 and maximum and finally the …
According to discharge in different ways, the ball mill can be divided into gate ball mill and overflow ball mill. The gate ball mill is enforced discharging, relatively the discharge would be coarser, but the capacity would be higher, usually the gate ball mill used for primary grinding, the overflow ball mill used for secondary grinding.
Overflow Ball Mill are generally used to grind materials with 1/4 inch and finer to the particle size of 20 to 75 microns. In order to achieve reasonable efficiency with ball mills, they must be operated in a closed system, with oversize material continuously being recirculated back into the mill to be reground.
A detailed case study of the ball mills operated in the 1–2 min residence time band was carried out to examine if 1 min can be used as a threshold of the volume-based residence time for the overflow ball mill capacity limit in the ball mill model.

Overflow Type Ball Mill 【Introduction】: A ball mill with simple structure 【 Capacity 】: 0.17~170t/h 【Improvement】: Wet type overflow ball mill is lined with Xinhai wear-resistant rubber sheet with excellent wear resistance, long service life and convenient maintenance
The overflow mill is better if the material needs to be ground to the fine products (150-200 mesh). 2. According to the production capacity. The grid type ball mill discharges the ore by relying on the grid plate, so its production capacity is higher than that of …
The grid type ball mill discharges the ore by relying on the grid plate, so its production capacity is higher than that of the overflow type ball mill. 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 ...

MQY Wet Overflow Ball Mill-Jiangsu Baisheng Machinery Ltd.-Introduction Baisheng MQY wet overflow ball mill is a cylinder with small diameter and big 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 …
One way of fully utilising the capacity of a ball mill is to convert it from an overflow to a grate discharge. This can allow an operation to increase plant throughput or reduce the product size, which can each contribute to higher revenue, but there are several factors to consider before the decision to convert is made.
Ball mill is one of the most variable and effective grinding machines which is mainly applied for further grinding the crushed materials. Compared with other grinding mills, the variety of grinding modes, available grinding tool materials, and flexible production capacity make ball mill grinders the perfect match for a vast range of applications, such as cement industry, new building …
The ball loading capacity of the mill can be calculated according to the formula (1-14). Gra — Quantity of Grinding Medium, T. Rho s — loose density of grinding medium, t/m3.
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 and can be divided into overflow ball mill and grate ball mill.
A ball mill with simple structure. Production capacity: 0.17~170t/h. Product Improvement: Wet type overflow ball mill is lined with Xinhai wear-resistant rubber sheet with excellent wear resistance, long service life and convenient maintenance.…
This ball mill is typically designed to grind mineral ores and other materials with different hardness, and it is widely used in different fields, such as ore dressing, building material field, chemical industry, etc. Due to the difference of its slurry discharging method, it is divided to two types: grid type ball mill and overflow type ball mill.
Compared with traditional ball mills, the grinding efficiency of the vibration ball mill is increased by 2-5 times and the energy consumption is reduced by 20% – 30%. Vibratory ball mills use high-frequency vibration to make grinding media in the cylinder produce inertial impact force. Raw materials are ground under the impact.
Three types of mill design are common. The Overflow Discharge mill is best suited for fine grinding to 75 – 106 microns. The Diaphram or Grate Discharge mill keeps coarse particles within the mill for additional grinding and typically used for grinds to 150 – 250 microns.
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.
