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.

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.

The 150T - Friction Screw Press designed & developed by Hari Machines Ltd. in the seventies is widely used for pressing all kinds of refractory materials. The superior performance & low maintenance requirements made it very popular even with the smallest of the refractory manufacturers. As of today about 300nos. of such presses are operating successfully with almost all refractory manufacturers in India.
Design- The press is closed frame construction consisting of base, head & coloumn rigidly clamped by tie rods.
Press Slide- The movement of press slide is guided by bushes moving over guide rods. This helps in avoiding any sizing problem in the moulds, particularly in the case of taper & key shaped bricks. This also minimises the chances of mould damage & reduces the incidence of rag rectification as well.
Floating Moulding Table- The mould table is suspended on four pneumatic cylinders & also firmly & properly guided in the columns. The table "FLOATS' during pressing to achieve the so called bottom pressing effect which improves the bulk density distribution from top to bottom of the brick.
Brick Ejection- Brick ejection is accomplished by pneumatic actuated slider-cum-locker mechanism. Ejection shaft lowering & lifting is contorolled by pneumatic valves.
Daspot Mechanism- Ejection shaft is connected to an oil daspot at the bottom to provide adequate cushioning effect during dropping of the bottom punch on the press bed.
Brake System- An effective brake system is incorporated by providing two spring loaded friction shoes which hold the flywheel in upper position in the pressing cycle. Effective functioning of the brake is ensured by proper adjustment in the operating mechanism.
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.
Construction- The mixer is of fixed pan design mounted on a pedestal. The mixing tools are mounted on the rotating Planetary gear box which is driven by a geared motor. The mixing tools comprise of 2 Nos. wall scrapers & 3 nos. mixing plough, made out of special quality hardened material for better life. Heavy duty roller & ball bearings are used which can take continuous load under different circumstances.
Portable Design- With the fixed pan mounted on a pedestal, complete machine can be transferred even to the application site by truck/overhead crane. Rigid structure ensures vibration free operation without foundation.
Discharge System- Hydraulic actuated side discharge arrangement is there for smooth and quick operation. Also motorised side discharge system can be incorporated optionally.
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 adjustment 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.

The brick linings of converters particularly trunnions, are submitted to mechanical stresses, thermal shocks and metal/slag corrosion. These areas are repaired by gunning in order to increase the life of the converters. The main advantage of a shooter equipment is the remote controlled system which allows the operator to move away from heat, and to conduct easily a gunning operation.The gun to which material is fed from the conveying unit - basic gunning m/c acts as the manipulator i.e. it has got all the basic movements (swiveling, tilting, rotating, forward, backward) so as to reach every corner of the converter for easy maneuvering during hot repairs. The manipulator is mounted on a transporter, which is diesel driven and thus can move to every corner of the converter shop and also can be easily positioned before the converter.Material from the basic gunning machine is fed to the gun via feed hose by compressed air. Water is added to the material at the gun while being conveyed pneumatcally. The mixed material is sprayed at the intended position by the same blast of air.The operator through a remote control panel positions the gun inside the converter at a correct distance & angle from the desired spraying point . The operator can easily guide the manipulator inside the converter so as to uniformly deposit the spraying material at the eroded portion.
