Application

The primary aim of the Drum Sieve is to separate coarse impurities like straw, strings, stones, wood, paper, leaves etc from various cereals and grains in the intake section of the mill. The machine is suited to separate impurities such as Straw, String, Stone, Wood, Paper, leaves etc. . A specially designed aspiration hood removes majority of dust and light impurities. The machine  helps to reduce the amount of wear and tear on the subsequent machinery in the cleaning section. It also helps in keeping the environment dust free.

Key features:

  1. Very easy installationdrum sieve
  2. Less space requirements
  3. Low power requirments.
  4. High output.
  5. Solid design and negligible maintenance.
  6. Double operation (Scalping and Aspiration)

Construction

The machine is all metal construction with side inspection doors. An aspiration hood (with regulating valve) is provided to aspirate the stock to ensure dust free operation. the speed of the drum is set in such a way that the gravity is more intense than the centrifugal force, that helps to achive the maximum efficiency of the machine.

 

Operation :

The grain to be cleaned passes through a specially designed feed roll over the revolving sieve drum of SS Wiremesh which is open at one end.  The grain after passing through the sieve crosses through a strong air current in front of the said aspiraion hood. Thus dust and lighter impurities are taken away by the air current to the cyclone dust collector of the system to which the aspiration is connected. The cleaned grain is discharged through a hopper and the coarse impurities tail over to an outlet.

Applications

The Vibro Seperator Type VTRA is one of the latest developments in grain cleaning by machinery. It can be used both as preliminary and secondary cleaning seperator.

There being three controls (throw, stroke, inclination of sieve) the machine can be used in a large variety ofvirgo separator type
applications such as rice, wheat, paddy, barley, maize, all pulses, groundnut and oilseeds like mustard, soyabean, sesame, sunflower etc.

 

Functions

The main body of the machine has two decks of sieves - for renewal of both small and large impurities. The movement of stock along the sieve is brought about by the vibrating motion imparted by two vibrating devices at the feed end of the machine. Oversized and undersized impurities are taken through the spouts located at the side and bottom of the machine respectively. The cleaned stock comes at the tail end of the machine.

Key Features

  • Minimum maintenance, since moving parts in the machine are kept to the minimum. There is no other moving part except the vibrators.
  • Angle of throw can be adjusted to suit the application at site.
  • The stroke length can be adjusted as per requirment at site.
  • Screen inclination is adjustable. It is pre set at works at 1.0 to 13.5. For special applications, continuous adjustable system for screen slope can be provided on request.
  • Drive by means of double vibrators located at the feed end.
  • Free moving sieve box supported on specially designed rubber section.

The VJF type pulse jet filters are designed for use in grain, cereal and food handling systems as well as in machine aspiration systems. It operates continously and automatically , the only moving parts are simple diaphram valves. Dust laden air is allowed to pass through fabric filters, thus separating the dust from the outgoing air. The filter sleeves are cleaned by intermittent pulse of compressed air, sleeves are fitted on metal cylindrical frames and suspended below nozzles. They are secured to their supported flanges by quick release clips, a features that reduces maintenance time.

 

Designed for use in a Flour Mill as well as grain, cereal and food handling systems and cement industry. Dustpulse jet filter

Key Features

  • A full range of filter sizes .
  • High air to cloth ratio capacity.
  • Very low power requirments.

Application

Type-HPL Plansifter is designed for sieving process in the Flour Milling Industry. It can also be used for grading purposes in other field of Industry.

 

Operations:

The machine consists of a vertical nest of horizontal sieves, the whole assembly gyrating in a horizontal plane. plansifter-hpl
The ground stock is fed in the top and falls from sieve to sieve by gravity. Owing to movement of sieve, the stock resting on it becomes strarified, thus the finest Particles work down, whilst the largest ride upto the surface of the stock and tails out.

 

Special Features

The plansifter Type HPL represents the latest development in sifter design and technology. this Plansifter is a high capacity machine having square sieves. The range of its feed section is four and eight and can make upti=o eight separations per section. Each section can be further divided into two to give more flexibility of scheming. All sieve frames, sieve housinga nd Flow channel are fully laminated thus making the machine highly waer resistant which also meets all criteria for durability and hygine. The sifter can handle 30 to 40% higher capacity due to the adoption of latest production techniques.

Vashist Indent Cylinder (Length Grader) is used in cleaning and grading various types of seeds and cereals. It separates shrivelled, immature and broken grains from whole grains by length.

The machine is primarily a horizontal rotating cylinder made of a special carbon steel sheet with pressed indents. The material to be treated enters the machinethrough the feed hopper and is taken up by the indents of the rotating cylinder. The short and broken grains are lifted by the indents into the collecting tray. Longer grain tail out of indents and are passed to the delivery end. There is an indicator scale provided at the tail end of the cylinder which indicated the position of the collecting tray. The position of the tray can be adjusted by a hand wheel to achieve the best separation possible.

Key Features

  • The machine can be used in parallel or in series to obtain two or more separations from a single feed.
  • The machine is such designed that the collecting tray can be inverted to clean the tray thoroughly and quickly.
  • The indented cylinder has been made split to facilitate easy cleaning or cylinder change.
  • To ensure double cylinder replacement life, compared to other locally available machines,the machine has been so designed that reversible indented cylinders can be turned , end for end when indents wear on one side.
  • To prevent dust accumulation, the machine can be connected to an aspiration system.
  • To offset the practical problems of noise and maintenance of variable speed devices a three step pulley drive device has been incorporated to achieve speed variations.
  • Comparatively higher efficiency and capacity is achieved due to about 18% more indents in unit area of the indent cylinder when compared with oter machines available in the market.
  • To keep the indent cylinder clean of any dirt accumulation, a newly developed brushing system with engagement and disengagement device has been incorporated.
