Calculating Output Speed Using Pulley Diameters and Input .
Your current ratio is 3.5/9 = .388 so any combination of pulleys that provides that ratio will maintain the speed. If you use an 8″ pulley on the fan than a 3″ pulley on the motor will be close. 3/8 = .375 ratio. If the motor is 1800 rpm your current fan speed is 1800(.388) = 698 rpm. A 3″ to 8″ pulley would give you 1800(.375) = 675

Dodge Heavy duty and Mine duty extra (MDX) drum pulleys deliver high performance and are available when you need them. Available from stock in many common sizes or custom made Dodge Heavy duty drum pulleys meet and/or exceed CEMA (Conveyor Equipment Manufacturers Association) application standards for use with conveyor belts rated up to 750 PIW (Pounds per Inch of Belt Width) / 131 kN/m.
Conveyor Tail And Drive Pulleys - Belt Conveyor Propulsion
The reducer is connected to the drive pulley with a chain . . . Now the Drive Pulley turns slower. All those parts (the motor the speed reducer and the drive pulley) are collectively called the conveyor drive. The Conveyor Drive. Drives must take up as little space as possible so the motor and reducer are put under and within the conveyor bed.

conveyor bed in the return section to support the return side of the conveyor belt. Drive/Head Pulley – A conveyor pulley used for the purpose of driving a conveyor belt. Typically mounted in external bearings and driven by an external drive source.
Drum & Pulley Lagging - All State Conveyors | Conveyor Belt .
Head tail and snub drums are subjected to continuous degradation and build up of debris. This is due to the repetitive fast high wearing environment and spillage from the conveyor belt. To safeguard your pulleys peak performance and your investment ASC would recommend shielding your componentry with high-grade rubber performance rubber lagging.

Single Belt Transmission - one driving pulley and one driven pulley. For a system with two shafts and two pulleys - as indicated with pulley 1 and 2 in the figure above: d 1 n 1 = d 2 n 2 (1) where. d 1 = driving pulley diameter (inch mm) n 1 = revolutions of driving pulley (rpm - rounds per minute)
3 Basic Conveyor Belt Tracking Rules To Follow - Accurate .
With conveyor aspect ratio (conveyor length to belt width) in excess of about 5 to 1 and in installations with reversing operations it is advisable to crown both head pulley and tail pulley. Following this method a correctly aligned belt can be maintained in its central position as long as there is no excessive deflection of the pulleys.
