Cement Testing Equipment

Product Details:

Laboratory Pulverizer is a disc type grinder. designed to grind virtually any material to produce a fine mesh sample in one operation. It is a self contained grinder. with a rotary disc. having a planetary movement in a vertical plane Grinding is done between two discs- one stationery and the other revolving eccentrically at high speed. The discs are made from heat treated ahoy steel, With the help of a convenient hand wheel, the size of the final product can be adjusted. This can be done. even while the machine is in operation. A self locking device holds the hinged grinding chamber in place and affords easy and quick access to it, for removal of ground samples and for cleaning. The Pulverizer has a capacity of reducing about half of a kilogram of a quarts type sample to 72 mesh in about a minute. The Pulverizer is fitted with a 3 H.P. motor, a 'V' belt pulley drive and mounting

Proving Rings are used for load measurements and are used in the outfits of a number of Soil/Cement & Bitumen Testing Equipments like Direct shear Test Apparatus, Triaxial Shear Test Apparatus, C.B.R. Test, Uncontained Test, and Marshal Test etc.

Proving rings can be designed to measure either compression or tension forces. Some are designed to measure both. The basic operation of the proving ring in tension is the same as in compression. However, tension rings are provided with threaded bosses and supplied with pulling rods which are screwed onto the bosses.

 

The dial gauge readings thus obtained versus load applied enable the operator to find out unknown load, just by nothing the dial gauge reading for the unknown load. The proving rings have high elasticity and on removing load the regain their original shape provided they are loaded in their elastic limit

A dial gauge and plunger anvil are mounted on brackets clamped ton the ring body .The dial gauge is held perfectly rigid without the remotest chance of shifting due to in advent shocks or pressure exerted on it. The dial gauge plunger rests on an adjustable anvil.

Proving Rings range with 500KN capacity provided with ½ inch BSF female threads loading bosses and a loading ball nipple and steel ball are supplied with each ring. Rings of capacity are not thus threaded.

Each ring are individually calibrated and supplied with works calibration chart and a carrying case.

Calibration charts from Standard Laboratories for the Proving Rings ordered are also available at extra cost. All Proving Rings are Integral Type. Integral type Compressive Proving Rings of different capacities from 50 to 500KN are available.

Glazed tile test autoclaves device is used to evaluate a combination of glazes quickly, efficiently and at a low cost. Pottery and ceramic industries make an extensive use of glazed tile test autoclaves to determine the glazes of the tiles at different point of time. Though being of a same composition, at times the glaze of two tiles differs and this device helps in measuring such differences.

Glazed tile test are undertaken to determine any kind of defects in the glazing of tiles like the crazing, thermal expansion mismatch, moisture expansion, peeling, metal release etc. Glaze surface defects include crawling, metal marking, pin hole and blisters.

Some of the features of glazed tile test device are:

• Manufactured using latest technology which makes it efficient in performance
• Designed to match varied requirements of the market
• Available in popular dimensions and made out of standard quality materials
