This technology is air-pulsed jig which is best suited for areas where water is scarce and also where customers are particularly interested in keeping water contamination to a minimum. Since it uses no water and processes solely using air, it has a distinct advantage of not adding an undesirable increase in moisture content which is normally associated with wet processes. Typically in a Sponge Iron unit where minimum moisture addition is sought in the clean coal and the rejects could be used in the power generation through AFBC boilers, this jigging machine would be preferred by customers. To add to these features its fully automatic operation with analog measurement of bed depth, low capital investment and low operating costs makes Allair a very interesting proposition for the customers.

The Ring & Roller Mill is particularly suitable for obtaining the fractions. This mill, particularly useful for grinding refractory materials, is generally used as a secondary grinder in combination with an Air Separtor.

Construction- The body is of robust construction consisting of casing in two halves and three yokes for housing the roller shafts with wearing rings and plates complete with cover plates for dust protection. The grinding is done by one rind and three rollers. The whole Mill is compact unit to withstand the vibrations caused while grinding.

Grinding Tools- Three convex-shaped rollers and one matching concave-shaped ring (to prevent lateral displacement) do the grinding. The motor drives the top roller which in time drives the rind by frictional contact. The ring in turn drives the two bottom rollers. Manganese Steel is used to give longer life to the rind and rollers. The rollers are pressfitted on the roller shafts which are supported at ends by the yokes on strong roller bearings.

Pressure Spring- Each roller is pressed against the ring by a pressure spring located between the casing and the yoke. The spring is centrally placed on the yoke to ensure uniform pressure distribution.

Economy- Due to its unique design features this Mill gives maximum economy of power of grinding. The beating and the frictional contact with the adjustable pressure gives remarkably high grinding effect. The material is continuously in circulation and stays inside the mill for a very short time. Hence, power consumption is very low compared to the high grinding effect.

Adjustment- The great advantage of the Ring and Roller Mill is that the fineness of the product can be adjusted to any desired size by simply adjusting the pressure spring. As wearing takes place in the Mill the springs are adjusted to maintain the desired fineness. The adjustement of the spring is very simple and can be done while Mill is running.

Safety- As the rollers are spring supported occasional tramp iron or big hardlump of material in the circuit will not damage the mill.

Environment- Due to minimum number of moving parts, the noise level of the Ring and Roller Mill is minimum. Extra care has been taken to ensure that it gives dust free operation.

Increased market demand for larger and denser bricks have created the need for heavy duty high capacity presses. The latest addition to Hari Machines Ltd. product range includes 800 Ton, Friction Screw Press with complete state-of-the-art technology. With the growth in Refractory Industry to cater to stringent quality requirements of Steel industry, the need for Heavy Duty presses was strongly felt.In the early 80's Hari Machines Ltd. introduced 400 T Friction Screw Press, indigenously designed and developed for manufacturing large high density refractory bricks. The machine became an instant success with the refractory manufacturers throughout the country. It was an ideal substitute for the imported hydraulic presses because of low capital cost.Keeping pace with changing trends Hari Machines Ltd. introduced The 800 TON.HSP designed & developed indigenously for the first time in India which was commissioned at O.C.L .

SALIENT FEATURES

Sturdy DesignThe press is closed frame construction consisting of base, head & cloumn rigidly clamped by tie rods

Hydraulic Pre-CompactionAdjustable pre-compacting strokes are given by hydraulic actuated press slide which can be pre-selected thereby controlling initial compaction of material.

Mould Car System with Floating MouldMould box is mounted on 'Floating' table suspended & firmly guided by sturdy springs along with guide rods. Entire assembly moves from ejection centre (located outside press) to pressing centre on a movable trolley which is hydraulic actuated. Trolley is locked at pressing centre during pressing. After completion of pressing trolley is unlocked and moves out to the ejection centre for brick ejection. Material filling to mould is done with the trolley located at the ejection centre. Depending upon the quality and type of brick 'Floating' can be controlled and also floating table can be locked in position if desired.

Vaccum Pressing ArrangementThere is provision of Vacuum pressing arrangement wherein the mould is sealed from top and bottom through rubber diaphram forming a sealed chamber which can expand or contract. The vacuum system, which comprises of a vacuum pump, control valves and tank creates vaccum in the flexible chamber after it has been completely sealed. When the specified degree of vacuum has been achieved, the initial pre-pressing is done hydraulically. The impact bumpings follows through screw spindle which moves independent of the press slide. When the brick gets shaped, air is allowed into the sealed chamber and the rubber diaphram along with press slide is retracted. The entire operation is automatic through PLC.

Adjustable 'Soft' and 'Hard' Impact StrokesInitial entry speed of the main screw can be preset & controlled for 'SOFT' initial compaction. Subsequent 'HARD' impact strokes are also controlled for intensity and ferquency. This control permits effective deairing during pressing and thus eliminates lamination.

Press Operation- Press up & down movement is accomplished by a operating handle with good leverage foreasy operation. Optionally pneumatic pressing system can also be supplied on request.

An air separator comes in handy when very fine materials are to be separated from coarse and where normal vibrating screens tend to have very low efficiency and give frequent trouble by choking etc. Fine materials of 200 mesh or more are separated from coarse when a material containing fines is passed through the separator, with a separating efficiency of more than 95%. This can be used for separation of even coarser materials upto 1 mm. The efficiency of the separator though tends to be lower as more and more coarse material is separated.

Working- Material is fed to the separator through a chute at the top which can be connected directly or indirectly to the outgoing chute of the mill. It falls through the admission cone onto a spray plate which is rotating at a high speed. This throws the materials towards the outside by centrifugal action. The various fans are also rotating at a high speed and they generate an air current the lighter material rises up, getting separated from the coarse grains. It passes through various fan blades, taking the path shown by the arrows. While moving up, further separations take place.When the air starts flowing downwards near the outer casing the fine material drops off and comes out through the cone of the outer casing. The cone can be fitted to chutes directly over the hoppers or to conveyors to transport the fines as desired. (Suitable air sluices may be provided if desired.) The air again goes into circulation through the shutters as shown

Construction- The fabricated steel plate body of this separator has been so designed as to provide ease in erection and transport. Since material is going to remain in contact with the casings, they are suitably lined with plates to increase the life of the body. All the fans are of removable type so that they can be easily replaced when worn out. Man-hole door is provided for easy access within the separator while changing of worn out parts and other maintenance work. Suitable adjustments are provided with the fans to control the fineness of the material to be separated.

Feed- For maximum efficiency the feed to the separator should be continuous and at a constant rate. If the grinding of the feed is uniform this also helps in better separation

With the increasing requirements of refractory castables and precasts, the need for quick and small batch mixing was strongly felt. To meet the growing requirement, Hari Machines Ltd. developed a portable design Planetary Mixer suitable for various castable applications (Dry as well as wet).

Mixing Principle- The mixer works on planetary principle wherein the mixing tools along with the agitator rotate inside the fixed pan at slow speed and simultaneously the agitator tools rotate in its own axis at a higher speed. The Planetary movement ensures a very homogenous mix.
