Advantages of this ball grinding mill include: less friction, less energy and more easily activated, because large diameter double row self-aligning roller bearing instead of sliding bearing is used as the main bearing. This ball grinding mill can achieve bigger capacity thanks to larger size of feed inlet and discharge outlet.
The mill has removable steel grates on the discharge ports to retain the grinding media and allow for the discharge of material. Optionally, Sepor can provide a ball retainer screen box. The mill comes standard with heavy duty bearings, full set of V- belts, a 15 HP/380V/3ph/50Hz or 220V/3ph/60Hz motor with motor mount and gear box.

Ball Mill Principle. The ball mill machine is mainly composed of cylindrical cylinder, end cover, bearing and big gear ring. Cylinder: The cylinder is filled with a ball mill grinding media (steel balls or steel cylpebs) with a diameter of 25mm-150mm. The loading capacity is 25%-50% effective volume of the whole cylinder.
We discuss the types of ball mill, the basic principles of the ball mill, how it works, the details of design including equations for optimum dimensions in all cases, some manufacturers for the ball mill, and estimation of the cost the ball mill. 6. 1. Introduction Ball mill is an efficient tool for grinding many materials into fine powder.
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.
If a ball mill uses water during grinding, it is a 'wet' mill. A typical ball mill will have a drum length that is 1 or 1.5 times the drum diameter. Ball mills with a drum length to diameter ratio greater than 1.5 are referred to as tube mills. Ball mills may be primary or secondary grinders.

The feed of the ball mill contains grinding balls. In order to effectively reduce the direct impact of materials on the ball mill feed bushing and improve the service life of the ball mill feed bushing, the feeding point of the groove in the feeding part of the ball mill must be as close to the side of the mill barrel as possible.

We can design and manufacture other type of ball mill according to the customer's requirement, or by the customer's mineral sample, capacity and size dimension.
The ball mill is a hollow drum closed with loading and unloading end caps, filled with grinding media and rotated around its axis.The drum of the ball mill (Pic. 1) is a hollow cylinder of steel, lined inside with armor lining plates which protect it from impact and friction effects of the balls and the grinding material.
Structure Features of Ball Mill. 1. Rotating Part. The tunnel body is made of steel plate (Generally speaking,the thickness: 1/100 of the tunnel body length). The feed port is connected tightly to the tunnel body by the bolts and a flange with two-"maze" groove. The discharge port is joint by an endcover and a tunnel flange, fixed by bolts.
The Inner Structure and Main Types of Ball Mill: Ball mill is mainly composed of feeding part, discharging part, rotary part and driving part which includes reducer, small drive gear, electrical machine and electronic control. According the materials and discharging method, ball mill can be divided into dry type ball mill and wet type ...

The overflow ball mills discharging speed is lower than that of grid ball mills. As a consequence, the capacity of the former is smaller than that of the latter, about 10% to 15%.
Our ball mills are industrial grade and designed for continuous operation, equipped with oversize roller bearings and a complete drive system. All wear parts are highly abrasion resistant and replaceable. The capacity, or throughput, of a ball mill is directly linked to particle size of the ball mill discharge.
Converting a ball mill from overflow to grate discharge involves installing a grate inside the mill at the discharge end. The grate holds the balls inside the mill but allows the slurry to pass through, and it is then pumped out of the mill by the pulp lifters. This is different to an overflow mill which holds the slurry and balls inside until ...
