Vor 2 Tagen· A heavily loaded inclined belt conveyor can slip backward when the drive is off. Such conveyors employ A conveyor belt is susceptible to static electricity as the belt is continuously pulled against the end pulleys. If electrical components are being conveyed, static electricity can be hazardous. Anti-static conveyor belt measures such as conductive belts or static control brushes

You say you have 6000 lb — presumably that's the total load on the 20 feet of belt at any given time. Suppose your belt is moving at 2 feet/second — that means that any given bit of load spends 10 seconds on the belt, and that you're adding 600 lb/second to what the belt is carrying. THAT is the mass that needs to be accelerated from 0 to 2 fps, requiring torque from the motor to do so.

A Conveyor Belt is the carrying medium of a belt conveyor (by an electrical motor) the belting slides across the solid metal frame bed, moving the product. In heavy use applications, the beds in which the belting is pulled over are replaced with rollers. The rollers allow weight to be conveyed as they reduce the amount of friction generated from the heavier loading on the belting. The

Industrial and mining applications move heavy loads that can be very abusive on conveyor belts. In addition to impact and abrasive effects of the material being conveyed, the conveyor belts are often subjected to conditions that cause damage, such as trapped material due to spillage, chute plugs, overloading, slip and other common issues. In these environments, keeping the belt running is
