Chute jam detector is a very important safety protection switch in belt conveyor system. When conveying materials causes chute jam, the detector can immediately send out alarm signal and stop belt conveyor operation, avoiding serious accidents such as material accumulation, conveyor belt damage and even fire from the source.
This product can effectively prevent conveyor emergency shutdown chaos caused by chute blockage, help you quickly control the risk of failure, and ensure the continuous, safe and stable operation of belt conveyor lines. It is an essential safety protection equipment for material conveying systems in mines, ports, metallurgy, building materials and other industries.
The product adopts the simple structure design of swing detection plate + limit switch, which is convenient to install and reliable to operate. It can adapt to harsh working conditions and flexibly adjust the detection force, which can meet the jam detection requirements of different transportation scenarios from fine particles to bulk materials.
Simple structure and reliable operation
Harsh environment adaptation
Flexible and adjustable detection power
Automatic reset maintenance-free
Product core characteristicsThe core structure consists of a swinging detection plate and a limit switch, which are installed at a reserved round hole in the chute wall. When the detection plate is pushed out by blocked material, the limit switch immediately triggers action. The structure is simple and has no redundant components, ensuring the stability and reliability of equipment operation from the root cause.
The detection board adopts a dustproof bearing suspension design, which can swing smoothly even if dust adheres to it. In order to prevent failure problems caused by dew condensation, a proximity switch type detector can be selected to adapt to high dust, high humidity and harsh working conditions such as mining and metallurgy. environment.
The detection force at the tip of the detection plate can be flexibly adjusted within the range of 9.8N to 14.7N, adapting to various transportation scenarios from fine particulate materials to large materials, meeting the chute blockage detection needs of materials with different specific weights and different particle sizes, and has a wide range of application.
For special scenarios such as moving dischargers, the detector should be installed on the side wall parallel to the running direction to effectively avoid misoperation caused by inertia; the automatic reset design can restore normal working conditions without manual intervention after the fault is resolved.

Note: For the chute used to move the discharger, the detector must be installed on the side wall parallel to the running direction to prevent inertia from causing misoperation
