proximity sensor

In mine crushers, the depreciation of parts is high and the presence of iron parts causes damage to the jaw or other parts of the crushing system, which increases the maintenance costs of the crusher. By installing this sensor in the jaw and feeder of the crusher, in case of observation and physical presence other than the stone, such as the sensor hardware, it announces the cut-off and shutdown of the device to remove iron from the device, reducing Also, the presence of iron in mineral products reduces the grade of the mineral and requires the separation of iron, which increases the costs and difficulty of executive operations. Therefore, identifying and removing iron before initial crushing reduces costs and increases the mineral grade. In the hydraulic system, by mistake of the operator and by raising the jack too much, the rotating part collides with the frame of the device, which causes excessive depreciation and increased costs. By installing this sensor and reducing the distance too far, the sensor is allowed not to raise the jack too much.

In the conveyor system of crushers, installing this sensor prevents overloading or its empty operation in order to reduce energy consumption costs and reduce maintenance costs. Also, if the conveyor is torn, it can be notified and the sensor can stop the conveyor to prevent further damage.

Other applications of this sensor can be used to control the amount of production and hours of non-operation. Thus, with proper management of the crusher and crushing system can be achieved by reducing costs to achieve optimal production.

Due to the dimensions of mining machines and the high blind spots of machines, accidents such as collisions between machines and other equipment always increase maintenance costs. The use of detection sensors in the blind spots of machines can increase the field of vision of drivers and operators to reduce collisions and accidents, and maintenance costs of machinery, which is a large part of the cost of mining workshops north This sensor can be used to prevent collisions in tunnels. By installing this sensor on the machines, in case of reducing the distance compared to other equipment, by announcing the warning, possible dangers can be prevented. Machinery and equipment announced to prevent damage to machinery.

Other applications of this sensor and using other sensors, can be used to determine the safety range of machines. Due to the darkness of the underground mine, night operations, high environmental pollution, and blind spots above the machines, installing This sensor in places out of sight of the driver and defines a certain distance, if people approach the machines and cross the safety distance of the device, warns people to reduce the possible risks of collisions with machines.

Due to the pollution of their work environment, such as dust caused by the operation of machines, dust caused by shot create operations, etc., reduces vision, which is removed by this sensor.

Purpose

· Reduce stress for users

· Significantly reduce the cost of depreciation and breakdown of the device

· Increase work efficiency and employee satisfaction

User Problem

· More job satisfaction

· Less fatigue

· Do their job faster

· the concern about the breakdown of the equipment they have

User Value

This sensor reduces the stress of drivers, crushers, and diggers for worrying about the breakdown of the machines at their disposal.

And their drilling forces feel that their work is going faster with the detection of iron and unusual materials by the machine.

Requirement Details

A proximity sensor, also called a proximity switch, needs to be able to detect surrounding objects without making physical contact with them, and it does the following:

Creating a field, electromagnetic beam (such as infrared or any light beam), sound pulse

• Signal propagation and radiation towards objects

• The signal hits the target object and changes the signal

• Receive a return signal due to beam collision

• Check and calculate changes in the field or return signal

• Identify targets according to the structure and type of sensor

An induction proximity sensor consists of a coil wrapped around a ferrite core (iron oxide) at the head of the sensor. An oscillating electromagnetic field is generated around this coil and an internal circuit (monitor) controls and controls it.

By moving a metal object around the sensor, an electric current is created inside the object. This current leads to a transforming effect, which reduces the internal energy of the coil.
