Electro Mechanical Vibrating Feeders

"Star trace" heavy -duty vibro motor powered vibratory feeder is a high frequency reciprocating machine of heavy duty capable on conveying bulk material from storage to processing or between processes at a continuous controlled rate of flow. Thus vibrating feeders are used in processing industries for handling all types of materials such as hot, damp, lumps, dusty or abrasive for various functions like flow material from storage, proportioning and blending, packaging, mixing, weighing, sprinkling, screening, scalping, crushing, washing, drying, heating, cooling, dusting, spreading, batching and etc.

"Star trace" heavy - duty vibrating feeders can be supplied with base mounted over hanging or combined single motor drive or with twin dual or dual twin motor drives or with multiple drives to serve as vibrating conveyors. These feeders are having a tray mounted on thedrive units. This drive unit is located beneath the tray.

"Star trace" vibratory motors are used in vibro feeders are totally enclosed 3 phase, squirrel cage induction motors with adjustable, eccentric weights mounted at both the ends of the shaft to set up vibrations during rotaion. The design of shaft and the selection of bearings has been carefully done to withstand heavy radial loads. Two identical motors mounted parallel to each other on a right and left, which is free to move in all directions, will produce to each other on a right and left, which is free to move in all directions, will produce linear vibrations. When connected for contra - rotaion so know this principle is adopted for handling large bulky material in large feeders.

Star Trace Power Saving Ball Mill – Energy-Efficient Grinding Solution for Ores & Minerals

The Star Trace Power Saving Ball Mill is a high-efficiency grinding device designed for the fine grinding of various ores and materials. Widely used in mineral processing, cement, silicates, refractories, fertilizers, glass ceramics, and chemical industries, this mill supports both dry and wet grinding methods. Depending on the discharge method, it is available in lattice (grate) and overflow types.

Purpose & Scope:

The Power Saving Ball Mill is essential equipment for secondary grinding after the crushing process. It is used to grind materials into fine powders, making it ideal for preparing materials in various industrial sectors such as:

• Cement plants

• Refractory manufacturing

• Metallurgical operations

• Fertilizer production

• Glass and ceramic industries

• Black and non-ferrous metal processing

It can efficiently grind a variety of hard materials, including ores, rock, coal, and other solid substances.

Working Principle:

The Power Saving Ball Mill is a horizontal cylindrical rotating device with an outer gear transmission and two grinding chambers.

1. Material Loading: The material is fed evenly through the feed device into the hollow shaft and then into the first chamber of the mill.

2. First Chamber: Fitted with ladder-type or corrugated liners and loaded with steel balls of varying sizes. As the cylinder rotates, centrifugal force lifts the balls, which then fall back, crushing the material by impact and grinding action.

3. Second Chamber: Coarser material passes through a single-compartment partition plate into the second chamber, which has a flat liner and finer steel balls for further grinding.

4. Discharge: The ground material exits through the discharge grate plate, completing the grinding process.

Key Features:

• Energy-saving design for reduced power consumption

• Supports both dry and wet grinding

• Heavy-duty steel construction for enhanced durability

• Available in grate type and overflow type configurations

• High efficiency and consistent particle size output

• Suitable for grinding rock, coal, minerals, and industrial raw materials

Applications:

• Grinding ores and minerals in metal and non-metal mining

• Powder production in cement and ceramic industries

• Size reduction for processing chemical raw materials

• Pulverizing refractory and abrasive materials

Note: While various grinding machines are used across industries, ball mills and rod mills remain the most preferred equipment for metal mining due to their grinding accuracy and efficiency in separating useful mineral components.
