In a mining operation, the conveyor belts are equipped with many rotary and movable components, which are exposed to human contact most of the time, demanding special attention.
Some basic cares are necessary to avoid the risks of accidents that may cause both damages to the conveyor components (with equipment halting, reduction of plant availability and production loss), and physical damages, which is the most serious.
Stone Extraction and Processing in North America
Pressure remains strong in the North American mining industry to minimize the cost of stone and ore production. A ten-year trend of passing some of the production costs directly to customers continues.
The locations and physical requirements of these two types of mines vary. However, there is one common thread between them. They both need reliable and compact conveyor belt drives to handle bulk materials in harsh environmental conditions.
The motorized pulley structure
The motorized pulley (also known as “drum motor”) includes the use of an AC motor and a gearbox within the shell of a hermetically sealed conveyor belt drive pulley. Sealing and lubricating a motor and gearbox within a pulley shell protects all moving parts while minimizing the space occupied by the drive.
The pulley is partially filled with oil to lubricate the moving parts and cool the motor. “drip lips” are welded to the inside of the pulley shell to pour oil onto the motor stator like a waterwheeL The oil draws heat from the stator and continuously transfers it to the pulley shell.
The conveyor belt then acts like an infinite “heat sink” to pull heat from the pulley shell and maintain an appropriate steady state heat for the drive system .If you want to get the price of the mining of belt, just feel free to contact us,we would be help u with kind.
The purpose of manufacturing conveyor drives in this manner is to accomplish these five goals:
• increase system reliability.
• minimize conveyor drive size and weight.
• decrease maintenance expense.
• improve operator safety, and lower electrical power cost.
Mobile Crushing and Screening Equipment
Ten years ago North American mobile crushing and screening plant manufacturers turned to motorized pulleys as they sought to improve the design of their equipment. Now American, Canadian, Norwegian, and Swedish mobile plant manufacturers all use motorized pulleys as standard equipment.
Because motorized pulleys require no cantilevered motor, gearbox, and V-beit assembly, they are also commonly used to drive crusher recirculating belts, under screen belts, and screen feed belts.
