These switches are designed for the safety of people and machines to avoid accidents and to stop the machine in an emergency. In belt conveyors, belt sway can result from uneven loading, misalignment of the idler set, and worn surfaces. Belted sway switches are useful to limit belt swings to tolerable limits. It is best to install the belt swing switch every 15 to 20 meters on both sides of the belt conveyor.

Belt Sway Switch is a protective switch for detecting the meandering (sway or deviation) of belt conveyors, and automatically sends out an alarm signal and an emergency stop signal once belt conveyors occur any sway or deviation. Working Principle When the meandering (sway or deviation) happens during the operation of belt conveyor, belt conveyors will touch the touch roller and make the touch roller meandering (sway or deviation), If the touch roller deflection angle is up to 1 level switch angle, the switch will send out an alarm signal. When the belt conveyors meandering (sway or deviation) seriously and is up to 2 level switch angle ,the switch will send out an emergency stop signal then the belt conveyors will stop automatically because of the meandering fault. After finishing the troubleshooting process, the belt conveyors will normal operation, and then the touch roller will realized automatic reset and return to the original state. Installation and Adjustment 1. The Belt Sway Switch can be mounted along the belt conveyors on the two sides, touch rollers should be perpendicular to the surface of belt conveyors and make the two sides of belt conveyors located in the 1/3 height of the touch rollers. 2. The optimum spacing between the touch rollers and the normal position of the belt conveyors is 50~100mm. 3. The conveyor length, type and the installation will decide the use quantity of belt sway switch. Belt sway switch generally mounted on the head section, tail section, convex curved section, concave curved section of the belt conveyor or mounted on the middle section of the belt conveyor. (Note: If the belt conveyor is longer, belt sway switch can be mounted on the middle section of the belt conveyor and each 30~35m can be installed one. 4. Belt sway switch should be contact with the belt conveyors intermediate frame via mounting bracket, switch bracket should welding with the belt conveyor frame after finishing the installation of the belt conveyor, belt sway switch and belt sway switch bracket should fixed with bolt. Application 2 level belt sway switch is widely used in the normal belt conveyor: underground, ropeway supporting belt conveyor: ship handing system; stacking/feeding conveyor; inclined and shuttle conveyor; crane, excavator, booms stopper: apron feeder/conveyor: heavy duty limit switch is a protective switch for detecting the meandering (sway or deviation) of belt conveyors, and automatically sends out an alarm signal and an emergency stop signal. It is widely used in metallurgy, coal, cement mining, electricity, port chemicals and other fields. Specifications 1. Nominal Voltage: AC380V 2. Rated Current: 5A 3.

hello to all experts We have recently replaced the steel chord belt of our Kiln feed elevator, we are unable to cotrol the sway of belt at its bottom and elevator gets tripped due to belt sway switch setting of 50 mm.we have replaced the head drum lagging,tail drum (bar type) and checked the brgs. of head and tail drum.we have noticed some manufacturing defets in belt, that the sides of belt are not straight at some places and these are wavy,can this affect the running of belt , for your reference i am attaching photographs of belt. pl. suggest how to control the sway.

Dear, 1. Tripping of Kiln feed B/E by 50 mm belt out on same side from top & bottom or only bottom side. -------If B/E current with belt sway tripping provided than belt can adjust to avoid tripping by belt sway fault in running condition. 2. what is shore hardness of your belt joint with respect to belt hardness. 3. why belt mfg make uneven edge of belt. With regards GKS

The hopper picks up the material from the underlying storage, and as the conveyor belt is lifted to the top, it rolls over the top wheel and then flips down. The bucket elevator pours the material into the receiving tank. The drive belt of the belt bucket elevator with belt drive is generally equipped with rubber belt, which is mounted on the lower or upper drive roller and the upper and lower redirection rollers. Belt bucket elevator: suitable for lifting from low place to high place. The supply material is automatically transported upwards and continuously after the material is put into the hopper through the vibrating table.
The standard configuration adopts the orthogonal shaft reducer and the fluid coupling, and is equipped with a backstop device. The transmission structure is compact and the flexible transmission is realized. It can not only stabilize the operation, but also protect the motor, reducer and traction parts.
Here are mainly steel buckets and high molecular polyethylene buckets, as well as shallow buckets, deep buckets, guide buckets, combination buckets, dewatering buckets, etc., which can be selected according to material characteristics and unloading methods. The bucket elevator can be equipped with a tear-resistant steel cord conveyor belt as the traction member, which has good toughness and high strength.

Plate feeder (plate feeding machine) is a kind of continuous conveying material machinery, which is used for continuous and uniform distribution and operation of materials along the horizontal or inclined direction for the crusher, conveyor or other working machineries. It can work reliably in high temperature and high humidity harsh environment, especially it is most suitable for transporting large and sharp materials of high temperature , and can work in humid harsh environment outdoors .
2The torsion force of the apron feeder is very large, so the bearing position is generally used with the discharge sleeve in the design. When the clearance between the discharge sleeve and the shaft has error, with the long time of use, it will inevitably lead to the bearing moving, and then aggravate the wear of the bearing.
3Because the bearing is installed on the release sleeve, the axial force positioning is mainly positioned by the front reducer against the spacer sleeve , when the reducer shuttles, it affects the stability of the bearing fixed, resulting in axial shuttling, and then the wear of the bearing.
The advantage is that it can be repaired online, but the disadvantage is equally obvious. Brush coating is limited by the wear, the general brush coating thickness is less than 0.2mm. When the wear is greater than 0.2mm, the efficiency of the brush plating will be reduced, and when the brush coating is too thick, the brush coating is easy to fall off in the process of use, and the service life is short.
Repairing by welding machine is one of the most common ways in traditional repairing , which is characterized by high repairing precision. The disadvantage is that it is easy to cause stress concentration or bending deformation of the shaft in the repair process of the small shaft. Repairing for the bearing position of the apron feeder and other large shafts can not be repair immediately while disassembly and transportation will increase the repair cost and repair cycle, and for high machining equipment requirements and the low comprehensive cost performance will affect the normal production of enterprises and increase the maintenance cost.
For the wear and tear of the bearing of the plate feeding machine, the method of replacing parts with other parts is not only high cost, but also high supply cycle ,disassembly and transportation, which is generally not adopted by enterprises as a last resort.
Above we introduced Analysis of Varied Repair Methods and Options for Wear at the Bearing position of the Plate Feeder (Apron Feeder). The HENAN EXCELLENT MACHINERY CO.,LTD is a professional bulk material conveying equipment manufacturer.

The bucket elevator is equipped with some protection switches. The protection switches will give early warning of possible accidents, and also to be connected to the central control room for real-time monitoring of the operation of the bucket elevator.
The gearbox can be equipped with auxiliary drive according to the need. When the main motor has an emergency failure or the bucket elevator needs maintenance, the auxiliary drive will start and the bucket will run at slow speed.
Gravity+Spring tensioning device is used in the tail part of the bucket elevator to realize automatic tensioning. Constant tension force can be maintained after one installation adjustment to avoid belt slipping or chain taking off.
The drive pulley of belt bucket elevator can adopt segmented diamond-rubber plate. When the drive pulley wears out, just replace the diamond-rubber plate which reduces the maintenance cost and save repair time.
