Cement & Steel industry background

India is the second largest producer of cement in the world & was the world’s second-largest steel producer with production standing at 111.2 million tonnes (MT) in 2019. No wonder, India's cement & steel industry is a vital part of its economy, providing employment to more than a million people, directly or indirectly. Ever since it was deregulated in 1982, the Indian cement & steel industry has attracted huge investments, both from Indian as well as foreign investors.

Cement production reached 334.48 million tonnes (MT) in FY20. The cement production capacity is estimated to touch 550 MT by 2020, whereas India’s finished steel consumption grew at a CAGR of 5.2 per cent during FY16-FY20 to reach 100 MT. India’s crude steel and finished steel production increased to 108.5 MT and 101.03 MT in FY20P, respectively.

Export and import of finished steel stood at 8.24 MT and 6.69 MT, respectively, in FY20P.

With this increasing demand, the quality of cement & steel is increasing and thereby increasing the need for separation of Ferrous particles from the raw materials, final product etc.

Hence, PML with its 60 years in this industry has been successfully manufacturing and supplying high end quality products to almost all the big players in the Cement Industry. Please find a brief description of PML products which are mostly used in the cement industry.

  1. Magnetic filter :

    Magnetic filter is the preferred product which is used in liquid & semi liquid process lines. The high power magnetic elements (rods) present in it are able to catch fine iron particles also from the product. The construction is in SS , and provides good corrosion resistance. Available in 12000 Gauss power also.

  2. Magnetic grill :

    Magnetic grills are preferably used for dry powder or granular like products. It also contains high power magnetic rods which are able to catch fine iron articles. Available in square & round shape which makes it easier to place into the material feeding hoppers. SS construction provides good corrosion resistance. Available in 12000 Gauss also. body construction. Suitable to use for vertical process pipelines.

  3. Magnetic drum separator :

    It is the ideal separator to use where self cleaning of iron impurity is required. Suitable for continuously running production. Available in high power i.e 4500 Gauss. Effectively separates small (e.g. staple pins, wire thread, broken washer etc) as well as big iron particles (e.g. nut, bolt, nail etc.) No need of manual cleaning of iron impurity.

  4. Magnetic rod :

    This is the same rod which is used in magnetic grill, filter, drawer grill, chute etc. Can be used where space is less. Ideal to use for inspection purposes to check iron presence in the product.SS construction, provides good corrosion resistance.

  5. Magnetic chute :

    Magnetic chutes are used for products which are sticky in nature. The pointed magnetic rod present in it does not allow material bridging hence facilitates the material to flow without clogging. Designed to use in vertical pipelines. SS body construction.Door is provided for easy cleaning.

  6. Magnetic Hump :

    The Z type design helps to break lumps & facilitate to trap embedded iron material from the product. SS 304 & SS 316Stainless steel construction. The High power magnetic plates are hinged type & can be easily cleaned periodically. Most preferable for high volume poor flowing or abrasive materials. Available in two variants i.e. High intensity with Flux density of 4500 +/-500 Gauss for & Low intensity i.e with Flux density of 1200+/-500 Gauss for attraction upto 4” distance.

  7. Suspended permanent magnet :

    Suspended permanent magnet is preferred to use on a conveyor belt. It is hanged on the conveyor with the help of chain slings to catch any tramp iron (nut, bolt, rods, angle, plates) present in the material which can damage the crusher or blender. Flux density: 1500 ± 200 gauss. The maximum operating temperature of 450 Degree C.

  8. Magnetic pulley :

    Magnetic pulley is used in conveyor belt. It is installed at the discharge end of the conveyor. It help of chain slings to catch any tramp iron (nut, bolt, rods, angle, plates) present in the material. Available in two variants i.e. High intensity with Flux density of 4500 +/-500 Gauss & Low intensity i.e with Flux density of 1200+/-500 Gauss.

  9. Magnetic plate :

    Magnetic plate is used to install in the ducts to catch any iron particle present in the flowing material. Magnetic plates are preferable where the flow rate is higher & iron is not fine (micron size) particles. It can effectively catch nails, pins, wire threads, broken blades etc from raw material. Depending on the size the attraction range varies between one to four inches.Magnet plates are available in a wide range from 1200 Gauss to high intensity 4500 Gauss.
