Description : Dryer framing design will be depend on mill speed, we are providing heavy duty MS framing. The MS framing will be specially designed and calculated for carrying load and suitable for absorb a vibrating stress. The Press Section Mainly Consists Of Following Accessories : A group of MS felt rolls with anti-friction bearings, bearing housing and brackets. Doctor Holder with Doctor Holder arrangement for dryer cylinder. A set of Felt Stretcher is provided in each dryer group. A set of Felt guide is provided in each dryer group. MS fabricated framings for dryers will be provided. The whole assembly is mounted on CI base plates.

  Description : Paper machines have an extra smoothing process called a calendar, which is added to the dryer screen. The calendar consists of several rollers arranged vertically one upon the other. By running the almost dryer paper web between the rollers under high pressure, the paper is compacted and smooth. The finished paper web is wound up on a steel shaft (reel). The paper now contains 5 – 8% moisture content. The paper now has all the characteristics required for its end use, but must be cut into narrower reels by a slitter / rewinder. Conversion solutions for the highest efficiency and quality, machine calenders are indispensable for satinage of many paper grades and make an important contribution in the paper machine to the production of gloss and smoothness. With the increasing demand for the satinage process and the often insufficient technical equipment of the machine calenders, there is a large potential for modernization. The objectives of these rebuilds are: increased speed and efficiency, improved quality.

  Technical Specifications : The vibrating screen consists of a M.S. fabricated screening though with S.S. 304 screen plate or Nylon Screen plate having 3mm diameter holes. A shaft supported on two heavy duty bearings in a grease lubricated CI bearing housing is fitted to the centre of the screening trough. Two in-balanced weights are provided at both ends of the shaft for attaining vibration. The screening trough is freely carried on 4 nos. Coiled springs which rests on a M.S. fabricated bottom vat. The bottom vat is provided with adjustable partition for maintaining the level of the accepted pulp. A nozzle is provided on the bottom vat for the collection of accepted pulp. A shower pipe is also provided on the screening through for washing off good fibres which adhere to the rejects. The bottom vat is provided with hand holes for cleaning purpose. The Vibrating Screen is driven by a separately mounted electric motor by coupling directly to the screen through a flexible shaft.

principle : one of the basic principle of the extractor press says: is to squeeze out as much water as possible, where the wet fibre web passes between large rolls loaded under high pressure. features : in mould plant, removal of water, from the wet web through press section is very important. extractor press is the only press with works at 8% (±1%) consistency & that is the only reason. extractor press is selected as the 1st de-watering equipment in mould plant. in this process, bottom mould having a wire mesh of 40 & top roll is of bd. so both will have a technically self-explanatory easy water removal, without having a problem of web crushing.

The conical shaped diffuser in the turbo head slows down the accept velocity and converts it in to a straight pressurized flow enabling users to reduce inlet pressure requirements for a given flow and velocity. In addition the spiral guide welded to the vortex pipe conveys the inlet down ward away from the inlet nozzle avoiding any flow disturbance and initiating the centrifugal process. Centricleaner operates at consistency range of 1.5 to 2% against normal cleaner range of 0.6 to 1% consistency. Centricleaner bottles are arranged in planetary system with inlet header at the centre, distributing pulp stock evenly to all centricleaning bottles at constant pressure. Accept of all centricleaner bottles also collected in planetary manner at the centre. Rejects collect in closed loop in the reject header directly connected to reject pump feeding to secondary stage cleaner. Deareation system also provided for approach flow cleaner to remove air from pulp stock. Bottom cone of Primary bottles provided with ceramic cone for improved life and for efficient separation of heavy contaminates from pulp stock. Flexi glass with quick release fitment provided between bottom ceramic cone and reject header for easy cleaning of nozzles. Dilution at middle of cone provided to increase centrifugal action at bottom cone increasing efficiency of cleaners. Secondary stage cleaner provided with in built tertiary stage and auto flushing in reject chamber for fiber recovery and efficient disposal of heavy contaminates from the system. Features : Can operate at lower inlet pressure. Inbuilt with spiral guide vanes at inlet nozzle to avoid turbulence losses. Inbuilt with DLR system. (Light reject & air removal system). Higher cleaning efficiency. Less plugging tendency. Uniform turbulent free flows and no cross flows. Minimum payback period. Less Floor area – bottles arranged in planetary design. Longer life of bottles – ceramic bottom cone with dilution nozzle. Ceramic cone provided with HDPE cove to avoid damage during handling. No reject nozzle jamming – Flexi glass reject discharge for easy cleaning. No civil works – reject collected in header avoiding reject tanks. Reduce thickener size up to 50%. Power consumption reduced up to 50% in centricleaning.
