Tongxiang is conveyor equipment manufacturers ,we produce belt conveyor for bulk materials.The ore, rocks, and minerals that are extracted from open pit and underground mines have to be transported to trucks, storage piles, and processing facilities. This is usually accomplished via belt conveyor systems. These belt conveyors for bulk materials have to be able to withstand harsh conditions; they are outside, constantly moving, and hold tons of material, some of which may be sharp and abrasive. Since heavy, moving equipment, carrying tons of material can be dangerous, extra care should be taken to make sure belts are moving correctly, and at the correct speed.
To help ensure safety around the bulk process equipment and belt conveyors, there are a variety of bulk material belt conveyor monitoring instruments, tripping systems, and switches. We discussed conveyor protection switches in a previous article, but this article will expand upon some of the equipment that can help prevent accidents, protect equipment and reduce shutdowns.

Industrial process monitors watch operating processes for potentially hazardous conditions and activate an alarm when they occur.
There are motion monitoring systems that sense the speed variation of rotating parts and can detect under-speed, over-speed, and zero-speed conditions of machinery and systems. This not only helps keep workers safe from materials falling off the belt, but it also helps reduce downtime and increase productivity. Under-speed switches monitor the rotational velocity of a shaft or other rotating equipment to help monitor under-speed or slippage conditions. Alarms go off to notify workers when speed drops below an adjustable set point.
Blet Conveyor Protection Switches are used for position information, control signals, and to identify potentially hazardous situations with your process equipment. They utilize a rugged, heavy-duty design to protect your equipment, prevent accidents and reduce unscheduled shutdowns.
The belt misalignment switch is mounted on the top or bottom of belt conveyor stringers with its actuating arm adjusted to the outside edges of the belt. If the belt skews or misaligns, contacting the actuating arm and displacing it from its vertical position, a connection is made with one or more of the micro-switches. For example, a 10° displacement of the actuating arm activates an alarm signal to warn of a potential shutdown, allowing the operator to make adjustments and realign the belt. A 20° displacement will activate a signal to shut down the process in order to prevent or minimize damage to the belt.

We also produce various belt conveyor idler roller,such as steel roller,impact roller,return roller,hdpe roller and so on.If you need,contact us.
