It doesn‘t matter how heterogeneous the sample is – even household waste, construction waste, German recycling system bales or light shredder fractions from automobile recycling: Within five minutes, our extra-powerful double mill will reduce any of these materials into a representatively divided analysis sample with a final fineness of < 500 μm! This is the ideal solution for inexpensive preparation of heterogeneous materials for analysis according to the Technical Instructions on Municipal Waste (TOC) or for determination of the calorific value and chlorine content.WORKING PRINCIPLEOperating principles of the powerful FRITSCH Cutting Mill CombinationThe extra powerful FRITSCH Cutting Mill Combination consists of the Power Cutting Mill PULVERISETTE 25 and the Universal Cutting Mill PULVERISETTE 19. The entire sample is pre-crushed by the PULVERISETTE 25 then falls automatically through a funnel into a sample divider which divides the sample according to a 1:13 ratio by default. The division ratio is variable.This smaller sample is then automatically comminuted in the PULVERISETTE 19 down to a final fineness of 0.2 mm and drawn into the glass sample bottle by the connected FRITSCH high-performance Cyclone separator.Through selection of the cutting tool sets and sieve cassettes, the FRITSCH Cutting Mill Combination can be individually adapted to any specific application. All accessories of the PULVERISETTE 25 and PULVERISETTE 19 are available for this.FEATURESMaximum feed size 120 x 85 mmPatented fully-automated two-stage comminutionDefined final fineness due to interchangeable sieve cassettes 0.2 – 6 mm, (further sieve sizes available)Sample exhaustion via high-performance Cyclone separator in a collecting vessel 60 litresIntegrated sample division to reduce quantity for fine size reductionSample cooling during the comminution processProcessing of sample material with moisture content up to 30 %Exceptionally high material throughputCutting rotor and sieve cassette can be removed and replaced without toolsFRITSCH HIGH-PERFORMANCE CYCLONE SEPARATORThe extra powerful FRITSCH high-performance Cyclone separatorThe FRITSCH high-performance Cyclone separator completely made of stainless steel 304 is particularly indispensable in the analytical sector and in the food and pharmaceutical industries, and for the processing of heterogeneous mixtures of material, e.g. in the cement industry. Due to its high surface quality, it offers enhanced resistance to corrosive media such as alkalis and acids and is especially easy to clean with a wide range of possible cleaning agents, without leaving any residues. In addition, it can be completely dismantled, fully emptied, flooded and sterilised, and thus offers reliable protection against cross-contamination.TECHNICAL DATAWorking principlecuttingOptimal for material typesoft, medium-hard, brittle, tough, fibrous samplesCutting toolsrotor with V-cutting edges and fixed knives, rotor with straight cutting edges and fixed knives, disk milling cutter rotor with indexable inserts and fixed knivesMaterials of the cutting toolshardened stainless steel, hardmetal tungsten carbide, chromium-free tool steel, stainless steel 316L, chromium-free steel DC01Max. feed size (depending on the material and funnel)120 x 85 mmMax. throughput (depending on the material and sieve size)60 l/hFinal fineness (depends on sieve cassette - additional sieve sizes available)0.2 - 6 mmFeedingbatchwise/continuousRotor speed300/360 resp. 2,800 /3,400 rpm*Rotor peripheral speed1.57/1.88 m/s resp. 14.92/17.9 m/s*Electrical Details - other voltages on request400 V/3~, 50/60 Hz, 5380 WattEmission sound pressure level at the workplace according to DIN EN ISO 3746 (depending on the material to be ground, rotor and sieve insert used)LpAd = 78 dBWeight215 kgDimensions (W x D x H)on included undeframe 100 x 65 x 145 cm*depending on voltage and frequency The PULVERISETTE 25/19 with voltage of “/3~” can only be operated on a three-phase supply network.Other voltages and configurations on request!Alat Laboratorium Umum

Order No.  02.2000.00FRITSCH Mortar Grinder  PULVERISETTE 2OVERVIEWVersatile UseThanks to its special mode of operation, the FRITSCH Mortar Grinder PULVERISETTE 2 is the ideal universal grinder in the laboratory – for analysis, quality control and materials testing as well as for the mixing and homogenisation of pastes and creams on a laboratory scale. Its particularly gentle grinding by friction with almost no thermal load is ideal for the preparation of tablets in galenics. Using liquid nitrogen it also grinds difficult-to-mill samples with moist, fibrous or elastic structures. And the PULVERISETTE 2 is also ideally suited for mixing of solids or liquids and solids. With brief, reliably reproducible grinding and mixing times, it is loss and dust free. For final finenesses of between 10 and 20 μm, with a feed size of 6 – 8 mm and a max. sample quantity of up to 190 ml.WORKING PRINCIPLEGentle fine grindingThe principle of the Mortar Grinder is the oldest grinding principle in the world: using pressure and friction, the pestle, with its large grinding sur face, grinds the material against the walls and bottom of the mortar bowl. Your advantage: a particularly uniform and gentle grinding through friction, mixing or homogenisation of organic and inorganic samples with no thermal load – dry or in suspension at 70 to 80 rpm.FOR SPECIAL APPLICATIONS: CRYOGENIC GRINDINGFRITSCH ADVANTAGEThe PULVERISETTE 2 is ideally suited for cryogenic grinding, where the material to be ground is embrittled with the addition of liquid nitrogen. In this manner moist, fibrous or elastic samples such as tomatoes, rubber, synthetic resins or plants can be ground without problem in the stainless steel grinding set.EQUIPMENT / ACCESSORIESConfigure your Mortar Grinder PULVERISETTE 2 exactly to your specific applicationOnly available from FRITSCH: the mortar bowls of the PULVERISETTE 2 are rimmed regardless of the material, in a robust shell of shock-resistant plastic, which protects the actual bowl. This makes it particularly durable and the integrated all around grip ensures optimum working conditions. All FRITSCH mortar bowls have an extra high rim and are sealed by a sealing lip in the lid.For contamination-free sample grinding, select the grinding set of your PULVERISETTE 2 from seven different materials – the appropriate pestle and scraper are also supplied. A grinding set made of stainless steel without a plastic frame is available, especially for cryogenic grinding using liquid nitrogen to embrittle the material to be ground.

The maximum feed size for bulk solids is up to 25 mm. For batchwise operation, a 5 litre collecting vessel with filter hose is delivered as standard. A 30 litre collecting vessel with filter hose is also available for larger quantities. The final fineness depends on the selection of the bottom sieve and the breaking properties of the respective material. A final fineness of < 100 μm can often be achieved after the first step due to the powerful drive and a rotor speed of up to 4,000 rpm. The PULVERISETTE 16 offers highest operational safety: if the quick-clamping lock is opened unintentionally, a safety switch activates the motor brake so that the rotor comes to a stop in less than 0.5 seconds. WORKING PRINCIPLE Impact, Friction, ShearingComminution in the Cross Beater Mill takes place through impact, friction and shearing forces. The feeding funnel guides the grinding material directly into the centre of the grinding chamber, where it is comminuted between the cross beater and the teeth of the grinding insert. The selected bottom sieve determines the final fineness. The rotating cross beater also creates airflow through the funnel that accelerates the discharging of the ground sample into the collecting vessel. The supplied filter hose can be integrated here to effectively reduce the release of fine dust.FEATURESMax. feed size 25 mmFinal fineness < 100 μm already in the first step depending on the materialIdeal for the comminution of coal, coke, lime or slatePerfect for fast work with a high throughputEasy-to-change bottom sieves with perforations sizes of 0.12-10 mmEasy cleaning due to grinding tools that are removable without toolsSpeed adjustment for different applicationsBatchwise or continuous operation possiblePractical grinding chamber quick-clamping lockEasily replaceable impact plates 1.1 kW brake motor, adjustable speed of 2,000-4,000 rpm (in 200 steps)Toothed grinding tools made of stainless steelTrapezoidal and round perforation bottom sieves made of stainless steel in various sizesUseable as a table-mounted or free-standing instrument with support stand (order separately)Extensive accessories for simplifying your daily workTECHNICAL DATAWorking principleimpactOptimal for material typemedium-hard, brittleGrinding toolscross beaterMaterials of the grinding toolsstainless steelMax. feed size (depending on the material)25 mmMin. sample quantity40 - 50 mlMax. throughput (depending on the material and sieve size)approx. 80 l/hFinal fineness (sieve inserts)0.12 - 10 mmFeedingbatchwise/continuousRotor speed2,000 - 4,000 rpmElectrical Details200-240 V/1~, 50/60 Hz, 1500 WattEmission sound pressure level at the workplace according to DIN EN ISO 3746 (depending on the material to be ground and instrument configuration)approx.

The maximum feed size for bulk solids is up to 25 mm. For batchwise operation, a 5 litre collecting vessel with filter hose is delivered as standard. A 30 litre collecting vessel with filter hose is also available for larger quantities. The final fineness depends on the selection of the bottom sieve and the breaking properties of the respective material. A final fineness of < 100 μm can often be achieved after the first step due to the powerful drive and a rotor speed of up to 4,000 rpm. The PULVERISETTE 16 offers highest operational safety: if the quick-clamping lock is opened unintentionally, a safety switch activates the motor brake so that the rotor comes to a stop in less than 0.5 seconds.WORKING PRINCIPLE Impact, friction, shearingComminution in the Cross Beater Mill takes place through impact, friction and shearing forces. The feeding funnel guides the grinding material directly into the centre of the grinding chamber, where it is comminuted between the cross beater and the teeth of the grinding insert. The selected bottom sieve determines the final fineness. The rotating cross beater also creates airflow through the funnel that accelerates the discharging of the ground sample into the collecting vessel. The supplied filter hose can be integrated here to effectively reduce the release of fine dust.FEATURESMax. feed size 25 mmFinal fineness < 100 μm already in the first step depending on the materialIdeal for the comminution of coal, coke, lime or slatePerfect for fast work with a high throughputEasy-to-change bottom sieves with perforations sizes of 0.12-10 mmEasy cleaning due to grinding tools that are removable without toolsSpeed adjustment for different applicationsBatchwise or continuous operation possiblePractical grinding chamber quick-clamping lockEasily replaceable impact plates 1.1 kW brake motor, adjustable speed of 2,000-4,000 rpm (in 200 steps) Toothed grinding tools made of cast ironTrapezoidal and round perforation bottom sieves made of stainless steel in various sizesUseable as a table-mounted or free-standing instrument with support stand (order separately)Extensive accessories for simplifying your daily workTECHNICAL DATAWorking principleimpactOptimal for material typemedium-hard, brittleGrinding toolscross beaterMaterials of the grinding toolscast ironMax. feed size (depending on the material)25 mmMin. sample quantityapprox. 40 - 50 mlMax. throughput (depending on the material and sieve size)approx. 80 l/hFinal fineness (sieve inserts)0.12 - 10 mmFeedingbatchwise/continuousRotor speed2,000 - 4,000 rpmElectrical Details200-240 V/1~, 50/60 Hz, 1500 WattEmission sound pressure level at the workplace according to DIN EN ISO 3746 (depending on material to be ground and instrument configuration )approx.
