  Design to remove unwanted particles like Staples, Stones Screws, Nails, Pabbles and other debris from stock and it collected in the reject chamber. The Reject Chamber is provided with a glass which helps to observe the rejection collected in to chamber. Clogging free operation. It protects the rotating part of refiners, deflakers and other down stream equipment against excessive wear and breakage. Zero fiber loss. Motorized model is available. Customized HD cleaner up to 2500 LPM are also manufactured. Fabricated with S.S. 304 and 316 material.

Hi-Con pulper With Dilution Pulper   Slushing waste paper/broke/virgin pulp in a continues or batch operation. Low to medium consistency (4 to 6%) M.O.C. S.S. 316 to M.S. Sandwitch plate fabricated & as per requirement. Poconsumptionis reduced. Dynamically balanced S.S. Pulper impeller with hydrodynamically designed vanes. Easy Maintenance. Capacity up to 16 cubic meter.

  Open type head box made out of the S.S. 304 plate suitable for low and medium speed paper machine up to 350 m/min. Tapered flow header for uniform velocity conditions. Uniform cross direction basic weight profile. Two holly rolls maintain defloculation or fiber dispersion. Easy accessibility of inside area for cleaning & easy of operation. Stability of flow. Minimum Maintenance. Foam killing shower also provided.

Dryer Section   Dryer Section designed to optimize the drying rate, reducing the investment cost. M.S. Fabricated dryers up to 2.0 mt. Dia and 25 mm to 36 mm shell thickness and the width up to 5 mt. Dryer is suitable for 4 to 5 kg/ cm2 operating pressure. The dryers are mirror finished and the width up to 5 mt. Our dryer system components are designed to provide best drying efficiency and uniform drying control. Heavy duty cast iron framing is also available its excellent for vibration dampening. The drying cylinder can be provided with stationary syphons or inside bucket system for proper removal of condensate. (Optionally). For high speed application above 200 m/min rope feeding arrangement is provided.

Cylinder Mould With Vat   It is the heart of a paper/board machine. It controls stick flow, pickup on the felt part and is responsible for good single layer/multi layer formation & substance profile across the full web. Designed according to Production requirements. M.O.C of Cylinder Mould. We also supply phosphorous/S.S./ Bronze spiders with bronze strips with 10 gauge S.S. wire wounding on request. Tapered flow header for uniform velocity condition. Design type of Vat. Counter Flow Vat- This type used for mainly in Board M/C & Slow Speed. Uniflow Flow Vat- This type used for good formation of Craft board & duplex board.   DRY VAT TYPE Increase in formation pressure. Shortening of the forming zone. Reduction in the amount of water carry-over from the inside of mould. Possibility of regulation the flow speed of stock suspension in forming zone. Reducing the effect of centrifugal force.

ATS Pulper   Low Consistency (2 to 3%) Used for slashing of all type of waste paper and machine, Broke from paper machine. Power efficient pulper with continuous application. You can chose S.S. Perforated screen of 5 to 8 mm. Hole depending upon your raw material quality requirements. Different size depending on requirements from 3m to 14m volumetric, capacity.
