PROBLEM AND RECTIFIER

BELT RUNNING NOT SHOWING --

According to the control room, the running indication of Bc 101 is not coming. Again we isolated and racked out the acb breaker first and saw that the slide contact 19&20 no of Circuit of the breaker is burnt. Then we took out the slide hook of a spare breaker and put in it. After re-installing, put the breaker in service position. Then when the acb breaker was run, the running indication came in the control room.

OVER LOAD

Overload -:Hello friends, if overload is coming, then first look at the overload relay installed in the panel, whether the fault has come or not. If fault has occurred, make breaker system healthy by pressing reset bottom. If there is no fault in the relay then Em stop and pullcard comes before the relay under the circuit of the breaker. Therefore you have to physically check Em stop and pullcard switch at Jb location.

CRUSHER MOTOR 1&2

DESCRIPTION -

A crusher motor is an essential component of industrial equipment that is used to crush and grind materials such as rocks, ore, minerals, and other granular substances. The motor provides the power to drive the crusher and is typically a high horsepower, high-torque unit that can handle the demanding and high load applications in which crushers are used.

The primary function of a crusher motor is to convert electrical energy into mechanical energy, which is then used to drive the crusher. This is accomplished through the use of electromagnetics, which involves the interaction between magnetic fields and currents. Essentially, the motor generates a rotating magnetic field that interacts with the magnetic fields of the stator, causing the rotor to rotate and turning the shaft of the crusher.


In order to achieve the high torque requirements of crushers, crusher motors are typically designed with a high number of poles. This means that they have a large number of magnetic poles per revolution, which makes them capable of generating high torque at low speeds. This is essential for crushers that need to start up and overcome the initial resistance of materials that are being crushed.
Crusher motors come in different sizes and power ratings, depending on the particular application they are used for. Some motors can have power ratings of several hundred horsepower or more, while others may only have a fraction of that power. The size and power rating of the motor will depend on factors such as the size and capacity of the crusher, the type of material being crushed, and the operating conditions in which the motor will be used.
When selecting a crusher motor, it is important to consider factors such as efficiency, reliability, and durability. Efficient motors can help reduce operating costs by consuming less energy and minimizing heat generation, while reliable and durable motors can reduce the risk of downtime and costly repairs.

Another important factor to consider when selecting a crusher motor is the type of motor enclosure. Open enclosures are typically used for indoor applications, while enclosed motors are used for outdoor applications or in environments where the motor may be exposed to dust, moisture, or other contaminants.

In addition to the motor itself, crushers may also require an accompanying controller unit to ensure optimal performance and safety. The controller unit can help regulate the speed and torque of the motor, as well as providing protection against overload, overheating, and other potentially damaging conditions.

In conclusion, a crusher motor is a critical component of industrial equipment used to crush and grind minerals, ore, rocks, and other granular substances. It provides the power necessary to drive the crusher and is typically a high horsepower, high-torque unit capable of handling the demanding operating conditions in which crushers are used. When selecting a crusher motor, factors such as size, power rating, efficiency, reliability, and durability should be considered, as well as the type of motor enclosure and the need for an accompanying controller unit.
