MOISTURE METERS FOR COAL (ANTHRACITE), IRON-ORE CONCENTRATE, SALT AND OTHER HIGH-CONDUCTIVITY MATERIALS

7 Декабрь 2017

We have manufactured the first batch of FIZEPR-SW100.10.16 moisture meters designed to measure moisture content in coal (anthracite), iron-ore concentrate and NaCl salt.

These meters can also be used to control other high-conductivity bulk materials e.g. as potash moisture meters, soda moisture meters, aluminum hydroxide moisture meters, ore moisture meters, potassium salt moisture meters, etc. FIZEPR-SW100.10.16 is also applicable when measuring moisture content in iron-ore concentrate and other magnetic materials.

The FIZEPR-SW100.10.16 coal moisture sensor is similar to the widely used FIZEPR-SW100.10.6 bulk material sensor in its design and installation in hoppers and on belt conveyors.

As opposite to the FIZEPR-SW100.10.6 version used on conductive materials with a probe-covering dielectric case (tube) only, the new moisture meter ensures measurements at virtually any conductivity of a material measured, and without any dielectric layer between the probe and the material. The solution designed improves significantly sensor reliability when operated on abrasive and lump materials.

The FIZEPR-SW100.10.16 sensor is made entirely of AISI 321 abrasion-resistant steel. On request, the sensor can be made of AISI 420 spring stainless steel hardened to 58… 60 HRC featuring exceptional strength and abrasion resistance.

In its other parameters the FIZEPR-SW100.10.16 coal moisture meter is equivalent to the well-known FIZEPR-SW100.10.6 version and similarly uses the dielectric measurement method.

The measured volume of a material to be controlled is 10…20 liters. Such a high volume of a simultaneously measured material eliminates any effect of inhomogeneous moisture distribution in the material and loose material-to-sensor contact while enabling measurements of materials with a size grade up to 3…4 cm

 

 

 

The moisture meter is available in explosion-proof version to control moisture content in coal and other explosive materials. FIZEPR-SW100.10.162 sensor for high temperatures

The new moisture meter is available in the 10.162 version (see figure enclosed) for measurements at temperatures up to 200ºС.

 

The FIZEPR-SW100.10.16 moisture meter was originally designed to measure moisture content in sodium chloride (NaCl) in a hopper or conveyor belt flow. The moisture measurement range is 0 to 100%.

FIZEPR-SW100.27.x sensor The FIZEPR-SW100.10.16 moisture meter was designed in parallel with FIZEPR-SW100.27.х moisture meters similar to it in their operating principle intended to control the composition of sodium chloride slurry and other high-conductivity liquid materials in pipelines.

 

 

 

FIZEPR-SW100.27.х sensors are the result of FIZEPR-SW100.20.х series development and similarly made as a pipe with flanges. Working pressures (PN) are up to 160 bar, nominal bores (DN) are 50 to 100 mm. FIZEPR-SW100.27.х moisture meters are applicable in slurry control at cement production, measurements of coal-water slurry (CWS) fuel composition and salt slurry composition control (solid-to-liquid ratio measurement in a slurry flow).

Concentrate, W=10% Concentrate, W=13%FIZEPR-SW100.10.16 moisture meters were tested on iron-ore concentrate at Karelsky Okatysh and Evraztekhnika plants.

The instrument ensures iron-ore concentrate moisture measurement in the range from 0 to 15%, i.e. from the dry material to the liquid slurry where concentrate is under the water layer as shown in the photo enclosed.

Concentrate, W=15,7%
