Cylindrical measures are used to determine unit weight of concrete or fine, coarse and mixed aggregates, as well as for void content of aggregates. These measures are immune to cement paste and can also be used for unit weight and yield of fresh concrete. It also indicates the angularity, spherical nature and workability of fine aggregate in a mixture.

• These are watertight with top and bottom true and even.
•  Steel units are seam welded with bail handles; aluminum ones are machined to accurate dimensions and have integral cast handles.

Applications
There are mainly used for determining unit weight of concrete or aggregates. Some of the areas where they find application are:

• Testing crushed rock
• Cement & concrete industry
• Testing of crushed slag & crushed and uncrushed gravel
• Construction (Buildings, Roadways, etc.)

Salient Features
The important features are:

• The crusher is made of cast steel.
• The jaws of the crusher are made of manganese steel.
• The opening of the jaws is adjustable from 20 mm to 6 mm and its capacity is 200 kilograms per hour.
• The crusher is provided with a hopper at the top for pouring materials.
• The equipment is supplied with 3 HP electric motor, triple V-belt pulley type and mounting frame.

Components
The various components of jaw crusher are :

•      Crusher Frame
•      Jaw Stock
•      Pitman
•      Eccentric Shaft
•      Anti-friction Bearings
•      Crushing Jaws
•      Wedge Setting Block
•      Toggle Plates
•      Side Plates
•      Fly Wheels
•      Draw Back Strings & Fittings

Working Principle of Jaw Crusher
The working principle of these crusher is based on modern design, that is, "crushing without rubbing."

The equipment consists of two Jaws, one is fixed and the other moves back and forth. The jaws are positioned in such a way that there is a wide opening at the top, known as the gape, and a narrow discharge aperture at the bottom, set to the desired output size. The pitman lever moving on an eccentric shaft on bearing suspend the moving jaw on the center pin. The material held in between the two jaws are crushed by mechanical pressure.

Applications
There are very useful in aggregate industries for crushing rocks and stones. Some of the areas where they are commonly used are:

•  Building Construction
•  Roadways Construction
•  Aggregate Production
•  Concrete Preparation

For resistance of aggregate that is caused by wear two hollow cylinders are attached. These cylinders are closed at one end and are provided with tight fitted covers at the other end. The inside diameter of the cylinder is of 20cms and 34cms depth. These cylinders are mounted on a shaft at an angle of 30 degrees with the axis of rotation. The shaft rotates at 30-33 r.p.m through a reduction gear, coupled to a motor.

Suitable for operation on Three phase AC Supply with 440 volts & 50 cycles. The m/c is fitted with a push button and counter starter for easy user interface. Complete with abrasive charge the machine consists of 12 cast iron spheres of steel spares. The spares are steel balls that are hardened & are of approximately 48mm dia meter, each weighing between 390-445 gram.

This machine is used for determining the resistance of aggregate to wear by abrasion. Two specimen can be mounted simultaneously and then kept loaded by weights against a machined flat circular grinding surface. The grinding disc rotates at 28-30 r.p.m and two funnels release a continuous flow of Suitable sand for operation on 230 Volts, Single phase 50 Cycles A.C. Supply.

Optional: digital timer.

It is used for determining the resistance of flooring tiles to wear or abrasion.

It consists of the following :-

• A grinding disc furnished with a replaceable grinding path and rotating horizontally about its vertical axis.
• A circular tray enclosing the grinding disc.
• Holding device for test specimen.
• Reduction gear coupled to a motor for operation on 220 v, 50 Hz, single phase supply.
• Revolution counter. (Preset cumulative).
• A 7.5 kg weight to apply 30 kg load on specimen through lever.

Accessories:-
Thickness Measurement Jig with 0.01 mm x 25 mm dial gauge.

We are engaged in offering length gauge, which is used to measure sample sizes of aggregates, sand and fillers. The product offered by us has a hard wood base with vertically mounted metal studs. In addition to this, it consists of a steel plate on which eight steel pins are vertically mounted with the specified distance in between. Following are the working principles and application areas of the product:

 

Working principle of length gauge:

 

• Particle is elongated when its length is more than 1.8 mm of the mid-size of the sieve fraction
• Aggregate to be classified is parted into 7 sieve fractions from 63 to 6.3 mm and each part is examined separately
• There are 6 labeled openings between pairs of metal pins. These pins measure particles from each of the 6 sieve cut below 50 mm
• Elongation index is the mass of elongated particles failing to pass between pins as percent of the sample

Applications:

 

• Research & development
• Soil analysis
• Cement & concrete industry
• Ceramic industry
• Rock & aggregate testing

Thickness gauge, also known as flakiness index is an instrument used to select samples from aggregates, sand and fillers. They can also be used to determine the flakiness index of aggregates.

Salient Features

•  The instrument consists of a frame with a sliding panel.
•  The slot comprises of properly cut standard slots of different length and width.
•  They are usually made of steel with chromium coating.

Working principle of thickness gauge:

• A particle is said to be flaky when its thickness is less than 0.6 of the mid-size of the sieve fraction.
• This type of gauge has 7 labeled slots for rapid hand trying of particles from each of the slots.
• Flakiness index refers to the mass of all flaky particles, passing appropriate slots, as percent of the sample.

Applications
Thickness gauge finds application in following areas :

•    Cement & concrete industry
•    Soil study
•    Rock & aggregates industry
•    Ceramic industry
•    Research & development
