Level Measurement in Mining

Problems at the site

Raw material (ore stone) is charged from trucks to vertical shafts.

This level should be maintained at an appropriate level so that the conveyor receiving material at the bottom of shat does not break by the impact.

Level sensor should be installed for this purpose but there are some problems:

The next process (primary crushers) crushes ore stone.

This crusher process has a risk of overflow when bigger ore bites in the facility. Level sensor is useful to detect the plugging situation but there are some problems:

Solved by the Radar Level Transmitter

Non contact principle Radar Level Transmitter with superior followability provides stable level measurement without bad influence from flying dust or vapor.

It monitors storage level and tells to the next process.

• Protection case is recommended to protect the sensor from the rebounding ore stone.

Immediate detection for plugging situation to prevent overflow at the primary crusher.

• Installation at the place, where prevent direct vibration from the site, is recommended.

26G Radar Level Transmitter (Ver.2.0) has a faster followability so that catches even 10m rapid level change in only 2 seconds.

Microwave has a useful characteristic that can go through flying dust or vapor, so it provides stable measurement under such conditions.

Achieved by the technology

Non contact measurement away from the charging area can prevent damage from the rebounding ore!

Fast followability allows immediate measurement (detection) even when 1m size ore is charged!
