Es Em International started its operation in the middle of year 1986 and since its inception we are determined to work for the excellence. We have our factory for processing, grinding, segregation and stocking of various minerals in the outskirts of Jaipur City in Rajasthan India. Major Minerals we are trading are:

  • Acidic Ramming Mass​
  • Quartz Lumps/Grains/Powder/Sand
  • Feldspar Lumps/Grains/Powder/Sand
  • Hematite (Iron Ores & Oxides)
  • Calcite
  • Soda & Potash Feldspar
  • China Clay


"Feldspar is a common raw material used in glass making, ceramics, and to some extent as a filler and extender in paint, plastics, and rubber. In glassmaking, alumina from feldspar improves product hardness, durability, and resistance to chemical corrosion. In ceramics, the alkalis in feldspar (calcium oxide, potassium oxide, and sodium oxide) act as a flux, lowering the melting temperature of a mixture. Fluxes melt at an early stage in the firing process, forming a glassy matrix that bonds the other components of the system together. In the US, about 66% of feldspar is consumed in glassmaking, including glass containers and glass fiber. Ceramics (including electrical insulators, sanitary ware, pottery, tableware, and tile) and other uses, such as fillers, accounted for the remainder.

Our Silica Ramming Mass is high on purity. Silica Ramming Mass is also known as Acidic Ramming Mass or silica Mix, is used in Core less Induction Furnaces, for melting of scrap .They find their vast usage in various industries. We bring superior quality silica ramming mass which is acidic in nature having the melting point 3274 F. Lining is the imported part of induction furnace, Furnace performance is directly related to the lining performance.

It is manufactured under strict supervision of qualified & experienced work force. Proper check is exercised on magnetic process to assure iron free material and to assure proper composition of granules according to furnace capacity. The granulations of the mix are optimized keeping in view the furnace make and capacity, thus giving maximum and best results. It is characterized by thermal stability, corrosion resistance and wears resistance because it contains less binders, fire clay and moisture compared to plastic refractories.

We Keeping in view the different needs, different types of scraps, end products and several other factors, we have got different grades of Silica Ramming Mass for lining induction furnace.

Premium Silica Ramming Mass:This is the widely used grade of Silica Ramming Mass made of best quality quartzite. This shows at least 30-40 % better results as compared to other Ramming Masses.

Snow white silica ramming mass:Made of best quality of quartz available on this earth, most popular among small furnace

Ordinary silica ramming mass:Made of quartz, specially made for nali top of induction furnace.

Pre-mix silica ramming mass:Ready to use material for induction furnace lining, pre mixed version of KV-165 .We mix Boric Acid as per customer requirement

We manufactured silica Ramming mass under completely controlled conditions and the formulation is prepared with consultations of major furnace manufacturers. It is best suited to control:--

Reactivity of the refractory

Temperature in which reactivity takes place

Sintering characteristics of the lining

Density and strength of the lining

Other Detail:

HEMATITE is a high-density weighting material. The hematite ore used as a weighting agent in drilling fluids has a mica-like crystal structure ground to a particle size suitable for use in drilling fluids.


OUR HEMATITE is used to obtain mud weights in excess of 20.0 ppg in water based drilling fluids, 19.0 ppg in oil based drilling fluids, or any time that exceptional control is required of solids percentage for rheology control.


OUR HEMATITE has a specific gravity of > 5, which is 19% greater than the density of BARITE (4.1). Thus, for a given mud weight, a system weighted with HEMATITE will contain fewer solids by volume. A lower solids concentration will contribute to improved rheological properties, improved penetration rate and decreased overall mud costs.
