Lead Oxide Ball Mill

About Ball Mill

Ball Mill is a basic device in the modern world of metallurgy and is extensively used in a variety of applications. In the field of Lead processing, Dry type Ball Mills are used for conversion of Lead pellets into fine Lead Oxide Powder (Lead Oxide Free Lead), also commonly called Grey Oxide due to its appearance.

Typical specifications for Lead Oxide produced in a Ball mill are:

Apparent Density

1.40, 1.60

Grey Oxide Plant consists of the following parts which have been described below:

  • Preparation Unit
    Ball Mill
    Collection Unit

Ball Mill

A Ball Mill is a hollow cylindrical tube sealed from both the sides, rotating on its own axis. The tube is generally in mild steel construction with or without lining. This tube has inlet and outlet pieces attached to it on both ends. Lead pellets are fed into the tube from the inlet side and powder is sucked from the outlet end. These inlet and outlet pieces also double up as shafts on which heavy duty bearings are fixed for the purpose of rotation of the mill. Inward spirals are provided on the inlet piece whereas reverse screw is provided with the outlet piece for increasing efficiency of the unit. The tube as a whole, after the inlet and outlet pieces have been fitted, is turned for alignment. A girth gear is fitted on the tube of the mill. This is provided motion with the help of a pinion gear fitted on a shaft which is driven by a motor. Depending upon the size of the mill, desired rotations of the unit are attained through reduction by pulley & belt arrangements or by use of gear boxes. The motor used is a standard TEFC squirrel cage induction motor, provided with a Variable Frequency Drive (VFD) for fine tuning the rotations of the mill. The mill is seated on a heavy duty structural frame which is properly balanced to enhance stability of the equipment. An automated water pump with a spray mechanism is provided outside the tube to control the temperatures within the Mill.

Collection Unit

A Collection unit is also called Classifier unit, this is an integral part of the Grey Oxide Plant. The raw material which is fine grinded in the Ball Mill is collected in this part. The collection unit works on the principle of negative suction and entrapment. While negative suction in the system is provided by the Induced Draft Fan (ID fan), the collection unit itself consists of Cyclone (pre-filtration device) and a Bag Filter Unit (fine-filtration device).

Air carrying Lead Oxide powder passes through an involute single tube Cyclone.Major collection of powdered particles is done here.It is received either in open trays, plastic sacks or into conveyors to carry them to silos, as per arrangement in individual units. ID Fan is placed at the end of the system.
