The head pulley magnet named as head pulley magnet or dry drum permanent magnetic separator also, is a self cleaning magnet which removes foreign tramp ferrous metals from bulk materials on a belt conveyor or separate the non-magnetic materials out of magnetic materials on a belt conveyor.  The magnetic field adheres magnetic materials to the belt as all materials passes over the head pulley. The magnetic materials from the underflow can be safely captured together.

Large magnetic envelope angle design, magnetic envelope angle less than 180 degrees, increase the length of the separation area and the number of magnetic inversion, achieve the effective separation of magnetic materials and non (weak) magnetic materials.
Neodymium-iron-boron magnets are used in all magnetic systems to ensure high magnetic field intensity and large depth of action.
The demagnetization rate of magnetic field intensity is less than 5% after 8 years.
The magnetic system is protected by stainless steel plate to ensure that the magnetic block does not fall off.
The shell of the pulley is made of stainless steel and lined with wear-resistant rubber outside, which has a long service life.
When it is used as the driving pulley of the belt conveyor, the length of the conveyor should be less than 100 meters.

It is used for dry pre-concentration of magnetite ores with size less than 300 mm before grinding. Usually it can reject some gangues to improve the iron grade before grinding.

How do pulleys contribute to the operation of conveyor systems?

Pulleys play a critical role in the operation of conveyor systems by facilitating the movement of materials or products along the conveyor belt. Here’s how pulleys contribute to the functioning of conveyor systems:

1. Power Transmission: Conveyor systems typically utilize a motorized pulley, also known as a drive pulley or head pulley, which is connected to an electric motor. The motor rotates the drive pulley, which in turn moves the conveyor belt. The rotational power from the motor is transmitted to the belt through the drive pulley, enabling the continuous movement of the belt and the materials being conveyed.

2. Belt Tension and Tracking: Pulleys are used to maintain proper tension in the conveyor belt. Tension pulleys, also called idler pulleys, are strategically placed along the conveyor system to apply tension to the belt. These pulleys help to keep the belt taut and prevent slippage or sagging. Additionally, tracking pulleys are used to align the conveyor belt, ensuring it stays centered and runs smoothly along the intended path.

3. Load Support: Pulleys provide support for the conveyor belt and the load it carries. The belt wraps around the pulleys, and the load is distributed over the surface of the belt. Pulleys with larger diameters are often used at points where heavy loads are encountered to help distribute the load more effectively and prevent belt deformation or damage.

4. Directional Changes: Conveyor systems may require changes in direction to accommodate the layout or specific processing needs. Pulleys known as bend pulleys or snub pulleys are used to redirect the belt and change its course. These pulleys are designed to guide the belt smoothly around bends or corners without causing excessive stress or strain on the belt.

5. Speed Control: Pulleys can be utilized for speed control in conveyor systems. By using pulleys of different sizes or by employing variable speed drives, the rotational speed of the drive pulley can be adjusted, affecting the speed at which the conveyor belt moves. This allows for flexibility in the conveyance process, accommodating different material flow rates or specific operational requirements.

6. System Support and Stability: Pulleys, along with their associated support structures, provide stability to the conveyor system. They help to maintain the alignment and tension of the belt, preventing misalignment, vibrations, and excessive belt movement. Properly designed and maintained pulleys contribute to the overall reliability and smooth operation of the conveyor system.

Conveyor systems are widely used in industries such as manufacturing, mining, logistics, and warehousing. Pulleys are essential components that ensure the efficient and reliable movement of materials and products along the conveyor belt, enabling automated and continuous material handling processes.
