The selection of the proper size and types of vibrating conveyor is based on the following three factors.
1. Quantity of material to be conveyed. - This is usually stated in tons per hour. However, since the vibrating conveyor is a volumetric device it is necessary to select a unit to contain and convey the largest instantaneous volumetric flow rat which may occur. For example, if a conveyor receives material from a batch weighing hopper it must be sized to convey at the maximum rate at which material is discharged from the hopper rather than at the average hourly rate. If a conveyor is to handle unit loads such as foundry mold, the cross sectional area of the pan must be somewhat larger than the vertical cross sectional area of the load so the load will be contained without spillage.
2. Properties of the material to be conveyed. - Material properties include bulk density, particle size, abrasiveness, corrosiveness, stickiness and temperature. Bulk density, together with the capacity in tons per hour determines the volumetric flow rate. Particle size has two important aspects. First, the conveyor pan must be somewhat wider than the largest piece of material which will be conveyed -- in this regard, material has much less tendency to jam in pans with flared sides than in pans with straight or vertical sides. Second, materials of very small particle size may convey poorly and may have severe limitations on the depth of the bed which can be conveyed. Abrasive materials may require pans fabricated of abrasion resistant steel or liners of abrasion resistant steel, or rubber. Corrosive materials may require pans fabricated of, or lined with, special materials. Sticky materials may require special liners or coatings. The temperature of the material will determine whether standard non-expansion construction will be satisfactory or if high temperature of heat-expansion construction is necessary.
3. Environment in which conveyor is to be installed. - Environment would include ambient conditions (hot, humid, corrosive or dusty atmospheres) and the type of support available for the conveyor. High ambient temperatures may require a supply of cooling air for the motor, V-belt drive and conveyor drive and an air-oil mist lubrication system for the drive bearings. If the conveyor is to be installed in an elevated structure, adjacent to equipment which would be adversely affected by vibration or in an area with poor soil conditions, a conveyor with vibration isolators may be required.
The following table lists the maximum allowable material temperature for the Webster flat spring conveyors. It is intended as a guide only and is based on the assumption that the bottom of the pan is completely and continuously covered with a bed of material.
| MODEL | Standard Construction | Heat-Expansion Construction |
| FSL | 150°F | 500°F |
| FSM | 150°F | 500°F |
| FSH | 150°F | 800°F |
