Side Entry feeders are used on applications involving relatively large particles that can not be reduced by shearing between the rotor blades on the housing at the inlet. Side entry feeders are also used where fine products by this shearing action might cause damage to the system or create hazard. The inlet and outlet flanges are offset. Material entering from the side settles into the pocket of the rotor and particles do not get trapped between the blade and the housing. This type of feeders operates at fix speed and about 40% of the pocket capacity.

Sanitary Type feeders have both the bearings on one side like monoblock pump and the side cover can be opened and also rotor can be dismantled. As this type of feeder ensures high sealing performance. It is ideal for food and chemicals industries where frequent material change take place and better washing performance is required.

The material to be sifted is fed into the stationary cylindrical screen by means of a screw mounted on the rotating shaft. A series of paddles which rotate inside the screen without contact, centrifugally force the material against the screen breaking up soft agglomerates. Sub-sieve material (fines) that pass through the screen discharge into a collection hopper at the base of the machine. Oversize material and hard lumps (that cannot be broken by hand) traverse down the length of the screen to the overs outlet. An adjustable baffle plate at the end of the screen regulates the flow of overs.   Designed to meet high-capacity scalping and sifting for both large and small process applications, the Ricon Rotary Sifter proves its cost efficiency daily in the handling of a wide variety of powder, granules, agglomerates and other free flowing materials.

All clearances being perfectly sealed and lubricated with vacuum oil to achieve higher vacuum. Unique valve design virtually eliminates valve maintenance and noise.   Each pump is equipped with controllable Gas Ballast to provide good vapor handling capability.   Volumetric efficiency is as 80% los pressure (High Vacuum).   Rugged construction is simple design and low maintenance.   Air and water cooled construction.   Cage slide pin avoids consumable spares commonly required in other types of pumps.   A separate oil tank is provided above the pump with inbuilt design, which pours down the oil on the rotor and like other conventional pump the rotor does not remain immersed in the pump at all the time. This is the specialty of this pump which helps the user substantially in cutting down the cost of Vacuum Oil.

Everybody wants to have clean and pollution free air around, and since industries are more responsible for Air pollution. We combat this section. There are several varieties of Bag Filter   A Dust Collector is a system used to enhance the quality of air released from industrial and commercial processes by collecting dust and other impurities from air or gas. Designed to handle high-volume dust loads, a dust collector system consists of a blower, dust filter, a filter-cleaning system, and a dust receptacle or dust removal system. It is distinguished from air cleaners which use disposable filters to remove dust.   In reverse-pulse-jet Bag Houses, individual bags are supported by a metal cage (filter cage), which is fastened onto a cell plate at the top of the Bag Houses. Dirty gas enters from the bottom of the Bag Houses and flows from outside to inside the bags. The metal cage prevents collapse of the bag.   Bags are cleaned by a short burst of compressed air injected through a common manifold over a row of bags. The compressed air is accelerated by a venturi nozzle mounted at the Reverse-Jet Bag Houses top of the bag. Since the duration of the compressed-air burst is short (0.1s), it acts as a rapidly moving air bubble, traveling through the entire length of the bag and causing the bag surfaces to flex. This flexing of the bags breaks the dust cake, and the dislodged dust falls into a storage hopper below.   Reverse-pulse-jet Dust Collectors can be operated continuously and cleaned without interruption of flow because the burst of compressed air is very small compared with the total volume of dusty air through the collector. Because of this continuous-cleaning feature, reverse-jet dust collectors are usually not compartmentalized.   The short cleaning cycle of reverse-jet collectors reduces recirculation and redeposit of dust. These collectors provide more complete cleaning and reconditioning of bags than shaker or reverse-air cleaning methods. Also, the continuous-cleaning feature allows them to operate at higher air-to-cloth ratios, so the space requirements are lower.   This cleaning system works with the help of digital sequential timer attached to the fabric filter. This timer indicates the solenoid valve to inject the air to the blow pipe.

The RICON Dual Tunnel type diverters have been specially designed to route powders and pellets with minimum degradation in pneumatic conveying systems. The RICON plug type diverter is applied in the chemical, pharmaceutical, plastic, food and other related industries.   The RICON plug type diverter consists of an Aluminum housing and end covers in which a plug with two pipes is installed. All product contact surfaces are made from SS 304. Three approved silicone seals guarantee the sealing between housing and plug. The body is pressure tight, so ensuring no leakage to atmosphere. The standard diverter can be used in systems with positive pressures up to 3 bar g (static seals). The sizes 50-150 are optionally available for pressures up to 6 bar g (inflatable seals). The RICON Dual Tunnel Diverter Valve is supplied with a complete electro pneumatic control system, including solenoids and inductive position sensors. The standard diverter can be used for product temperatures ranging from –25 °C up to +80 °C at ambient temperatures of –10 °C up to +40 °C. Versions for higher temperatures are available on request.

Double Flap Valves, also known as Double Flap Valves or Double Flap Gates, are a type of airlock valve commonly used in industrial applications as a component in bulk material handling applications.   Double Dump Valves are primarily used to discharge chunky, pellets, granules or fibrous, bulk materials from hoppers, bins, and cyclones operating under positive or negative pressure.   Double dump valves are used to discharge a flow of material while at the same time serving as an airlock transition point to preserve the pressure differential above and below the valve.   This type of material handling valve is ideal for use with bulky or abrasive materials that would tend to jam or damage a Rotary Feeder   Double dump valves have two trap-door flap plates which open and close on an alternating cycle. The top gate opens to allow collected material to drop through onto the bottom gate. The top gate then re-closes to prevent air leakage above the valve. The bottom gate then opens to allow material to pass completely through the valve. The bottom gate then re-closes to prevent air leakage below the valve. This cycle is continuously repeated in order to maintain a steady discharge of material from the valve, while maintaining a positive seal on the system.   Each flap plate has its own pneumatically operated cylinder and solenoid valve. The timing of the valve is controlled by an electronic signal sent to the solenoid valves. This method of operation is design to provide first class automation with sequential controller for accurate timing of the desire functioning of the valve.

When used to seal Bottom Discharge of a dust collector handling a relatively light dust load and operating at not more than 300 mm W.G. static pressure the light series Rotary Airlock will generally suffice. For a heavier dust loading and higher pressure or other materials handling and feeding applications a heavy duty gravity discharge feeder should be used.

The Blow-Through feeders has been used for many years in flour handling systems and non-abrasive material conveying systems in large bakeries, flour-mills etc. Being an integral part of the pipe line, Blow-Through Feeder allows the material into a pressure pneumatic conveying system in a very simple and positive way. Feeders in this services has limited range of application involving products which are relatively non-abrasive such as flour, finely ground coating clays, koalins etc.
