Material is received from top in Rotary Air Lock Valve. Fills volume between rotor vanes and discharge at bottom side. Material is discharge without air leakage. It can be mount directly on bottom flange of silo of outlet spout.Rotary Air Lock Valve consists flange mounting type housing, rotor and rotor shaft. Rotor is fitted inside housing. Rotor rotates in bush bearings. Stuffing box with gland packing is provided both sides to prevent material leakage. Rotor is driven by geared motor and chain sprocket.

Nipped material pieces pass between two rollers. Material is crushed by passing through two rollers and collected at bottom tray. It can be nipped without slippage. Gap between two-roller need to adjust for getting desire material size and out put. Material size reduction ratio is 1-4 per pass. Production rate and energy consumption is affected by changing reduction ratio and differential roller speed. Roll design like smooth, grooved or water cool (for hot material) are offer to suit various requirement. The angle of nip varies for different operation.

Application : Industrial

Capacity : 15 to 50 kg/h

Voltage : 240 Volt

Lump is fed from the top. Wide flanged inlet area is for accommodate a greater mass. It has single shaft with evenly placed impacting fingers and fix comb on body. Shaft with Lump is brake between rotating finger and fix comb. Broken lumps are collected from bottom.It has single shaft supported on flange mounting bearings. Bearings are bolted on fabricated body. bars (fingers) are fixed at evenly placed on shaft. Similar size bars are fixed one side-wall of body. Bars on shaft and on body are staggered to each other. Shaft is driven through motor and pulleys. Fabricated body fixed on base frame. Rubber tyres are fitted at bottom of frame to move unit easily, where every you need.

Lump breaker is for size reduction at economical price. It is for increase productivity by reduce size of lump by using less time and energy. It reduces soft products such as dry cake into sizes that can be further processed. Compact machine can be placed to reduce material into manageable size for conveyor or process equipment. It is alternate of manual breaking of partially dried lump of material like Pigments, Dyes and colours etc.

All the data given are nominal only. It may vary widely from case to case depending upon many factors.Micronizing as well as classification is to be done in Varahi JetMill by taking advantage of fluid energy. Mill is designed to inject high pressure Air or Steam in to cylindrical chamber through Specialy designed Nozzle. Nozzles are placed at equally spaced on peripheral wall to have each Jet is tangential at imaginary smaller circumference. Venturi system is control fed rate of material very precisely to get productivity. Jets are generate high velocity vortex during material feeding which create vacuum to suck product into high speed vortex. Suspended partical of the material are collide with each other and reduce themselves by attrition as well as collision whenever it comes in strong velocity gradients near the jet. Micronised particals are getout with jet fluid through center of chamber and get collected into the cyclone collector system. Heavier or oversize particals are stay in to chember until micrinized due to Centrigugal force.

centrifugal screen is for screening Starch, pharmaceuticals, Animal feeds, Food product, Agro product, Agro chemicals, fertilizers, Gum powder, matel powder, Chemicals, Minerals, Agrochemicals, dyes, pigment, ceramics, minerals, paints, polymers, magnetic material, papers etc.New technology shifter is giving horizontal, vertical and circular mechanical vibration. Vibro Shifter is for screening dry powder OR wet medium. It is also useful for separation solid-solid OR Solid-liquid and classification of solid. It is rigid screening device, which vibrates with screen above its center of mass. Whole mass is suspended on coil springs, which gives thrust to screening unit by its own compression and de-compression. Spring allow unit to vibrates freely and also prevent transmission of vibration on floor. Number of screen decks and spacing frame assembled on circular base frame. Screen is uniformly tensioned in all direction by center support. Specially designed vibrating motor generates vibration. Eccentric shaft is fixed on both side extended motor shaft. Eccentric weight is rotate with motor and generates vibration of whole masks.

Rotary Air Lock Valve design: Rotary Air Lock Valve consists flange mounting type housing, rotor and rotor shaft. Rotor is fitted inside housing. Rotor rotates in bush bearings. Stuffing box with gland packing is provided both sides to prevent material leakage. Rotor is driven by geared motor and chain sprocket.Different design and construction of material for vanes and housing are offer for different application.
