Pulp Testing Instruments

Consistency determination apparatus for quick determination of pulp/stock consistency. The measured stock is poured on to the grid plate of the equipment and drained under suction.

The filtration is repeated until the filtrate becomes perfectly clear. After drying and weight of the sheet the consistency can be determined.

Optional : Vacuum pump Rapid Sheet Drier for shortening the drying time, as an optional accessory Couch Plate.

We Are prominent Manufacturer, Dealer, Supplier & Exporter of Fiber Classifier in Uttar pradesh, India. We Supply Fiber Classifier All Across india. These Fiber Classifier Are manufactured With High-quality Material. An agitated pulp suspension is fractionated by means of a screening process employing vertical screens with increasing wire sieve cloth numbers. The screens are mounted in tanks arranged in cascade.

The mass of the fibres retained by each screen and of those passing all the screens in determined and expressed as a percentage of the oven-dry mass of the original sample.

Fiber classifier consisting of five units mounted in cascade. Each units comprises a S.S. tank having the One of the flat sides has a rectangular aperture sealed by a detachable frame, which is clamped against a gasket. The frame is fitted with a slit plate and a wire sieve cloth, 335 cm2 (165mm x 23mm) in area and the lower edge of the frame is 50mm above the bottom of the tank .The slit plate, which equalizes the flow through the wire sieve cloth, can be removed from the frame. It has three vertical slots measuring the middle slot is located centrally with respect to the screen. The guide plate in the tank is mounted inside the screen and parallel and symmetrical with it. It has three vertical slots measuring 2mm x 190mm and set 41mm apart; the middle slot is located centrally with respect to the screen. The guide plate in the tank is mounted 14mm inside the screen and parallel and symmetrical with tank.

Floatation is a physical-chemicals process of separating materials. It is based on the phenomenon that separation is achieved by influencing the wet ability with water of the particles to be separated, whether the surface of these particles is hydrophilic or hydrophobic. The water repellency of the surface of the particles to be separated is achieved by the addition of special hetero polar chemicals, called collectors, which deposit on the surface of the particles. In the case of ore and mineral floatation, the polar metal- affined component of the collector deposits on the surface of the particle of the collector deposits on the surface of the particle so that the a polar component, mostly a CnN2n-1 chain, a with a dense packing of the adsorptive substance steeply erects on the surface of the particle, thus rendering it difficult to wet. At the same time, the treated particles can deposit on air bubbles that are introduced into the suspension, stabilized by frothers acting on the gas liquid boundary, as a result of the buoyancy of the air bubbles, the adhering particles are conveyed to the surface of the slurry or suspension to concentrate as froth, in which from they can be removed all hydrophilic particles remain in the slurry or suspension.

Lab Hydrapulper is a complete pulping unit used for marking pulp from secondary fiber waste paper, on lab scale. It can also be used for mechno-chemical pulping. It has 30 liters capacity and can be also made available in 10 & 20 liters capacity, if required. The tub made of stainless steel, is provided with lid to fit tightly on the tub. There is an outer cover on the tub to make an access to the heaters and their connections. Four Heaters of 500 W each are fitted in the double wall annular space of the tub with glass wool as heat insulation to provide the heating controlled through thermostat. The Helicon Turbine fitted inside the tub is driven through V-Belt by the 5 HP motor at 500 RPM, for the desired time duration to form the pulp, at around 80 0C. The pulp samples can be checked by opening the top lid at intervals to ascertain its readiness.

Beater of valley type is used for laboratory beating of pulp under standardized condition. The degree of betting can be varied. Beating is a preliminary step to the testing of the physical properties of pulp. In principle, this standard applies to all kinds of satisfactory results with certain extremely long fibred pulps, such as cotton linters

Apparatus :
The lab beater consists of a pulp chest of acid proof ground and polished internally. The pulp chest is divided in the centre and forms a circular basin in which the pulp can flow around. A hardened, portion separate the two halves of the pulp chest. The pulp between the beater roll and the beater plate. The beating pressure is controlled by means of the lever which is loaded with dead weights.

A measured quantity of pulp with a specific consistency is beaten between the knives in the beater. Samples of the beaten pulp are taken at predetermined intervals during the beating.

The Digester is a complete pulping unit for producing pulps by cooking wood chips in a manner similar to a commercial digester. The unit is easy to operate and features precise control of pulping variables to ensure good repeatability of results. Digital temp Indicator-cum-controller precisely control the temperature range upto-200 ^oC. The rotation with change in turning direction provide efficient agitation to the samples.

A pulp sample is said to be disintegrated when it has been subjected to mechanical treatment in water so that interlaced fibres, which were free in the pulp stock, are gain separated from one another without appreciably changing their structural properties.
