Electro Zavod India Pvt. Ltd. Howrah, West Bengal

ontrolled mechanical vibrations are used in the transfer of bulk material in the form of solid, powder or granule form. Controlled mechanical vibrations can be produced by setting predetermined frequency and amplitude.

The decision to select a particular vibrating screen is critical. It impacts the operating life, efficiency of screening, maintenance requirement, inventory cost, environmental factors and of course investment. A wrong choice could lead to bottlenecks in material flow, preventing the plant from working to its capacity. Electro Zavod screens are rugged and designed for a long life. Due to the vast experience of JOST and the wide choice of vibratory drives available, Electro Zavod selects and delivers the most efficient and economical screen for each individual application. Selection of the correct drive is very important for screening efficiency and highest possible output especially for prolonged usage over the life of the machine. Electro Zavod has the complete range of vibrating drives which enables us to make the optimum selection. Screening performance is affected by various characteristics of the feed material including particle shape, bulk density, flow-ability and surface moisture. Most important perhaps, is the particle size distribution of the feed. It is essential to choose the correct screening motion and configuration for performance and durability.

Slipring Assemblies are used for carrying electrical current from a stationary part to a rotating part of an equipment such as Rotary Crane, Rotary Reclaimer, Cable Reeling Drum, Excavator, Circular blenders, Rotatory Kilns etc.

The sliprings or the brush holders can be mounted either on the fixed or the rotating part of the machinery as per machine design. Rings of various amperages can be combined to form Slipring Assemblies and a combination of Power, Control and Communication can be offered.

Our design range caters to the following requirements -

• Slipring Current rating 15 Amps. - 600 Amps.

Electro Zavod Metal Detectors detect the presence of metals-both magnetic and non-magnetic in moving bulk material. Tramp Metal affects many Industries, and presents Quality Control problems or a Hazard to processing equipments i.e. Crushers, Ball Mills, Conveyor Belts, etc. Electro Zavod Metal Detectors meet the requirements of a wide spectrum of industries like Iron Ore, Metallic Ore, Cement, Coal, etc.
Electro Zavod Metal Detectors with rugged design and continuous heavy- duty usage, are field proven. Electro Zavods R & D and continuous innovations ensure the performance and reliability of Metal Detectors. Principle of Operation
Electro Zavod Pulse Metal Detectors operate on the principle of Eddy Current induced imbalance in a set of mutually balanced coils. A frequency of 20 KHz to 100 KHz is used to generate an electromagnetic field in the aperture area. The system automatically maintains a high degree of balance which is distributed by the metal passing through the aperture resulting in a signal, which is amplified to operate an audio visual alarm and interlock or reject mechanism system.
Electro Zavod Pulse Metal Detector
The Electro Zavod Pulse Metal Detectors works well with magnetic and conductive ores. No other system can work effectively when a tramp metal is to be detected in the presence of magnetic and conductive ores. The Electro Zavod Pulse Metal Detector detects 25mm MS sphere/cube and 25mm Al sphere/cube.

Circular Motion Screens are operated either by a mechanical exciter or two unbalance motors. In both cases rotation in opposite directions creates linear vibration. Linear motion screens are very high performance machines, in terms of capacity and efficiency. They have a low inclination which varies between 0 degree and 15 degree. The drive is a combination of high amplitude and low frequency of vibration.
