ALPINE SIEVE SHAKER TYPE LS-N-200 WITH SUCTION AND AIR JET
Standards: EN-196. ASTM C109,C184, C230 and C340
PRINCIPLE OF OPERATION The only thing that moves the materials being analyzed is the air flow.
This system works without any and all mechanical means of influencing the sieving process, e.g. tappers or brushes. Which means that at the same under pressure and same sieving duration, exactly reproducible particle size analyses are possible at any time.
The strong jet of air exiting the rotating slotted nozzle purges the sieve gauze continuously.
This leads to exceptionally short sieving times and ensures that even those materials which are known to cause difficulty can be sieved successfully.
The transparent plastic cover permits constant monitoring of the sieving process.
The integrated processor permits direct conversion of the sieve residue (g) into the undersize fraction (%). The sieving results are displayed on screen or can be printed out by a matrix printer.
The basic unit has two serial interfaces to permit connection of a laboratory balance, printer, under pressure controller, electronic tapper and for optional PC operation, with the LS-PRO software.

UNDERPRESSURE CONTROLLER The under pressure controller constitutes a process-technological enhancement of the 200 LS-N air jet sieve.
The sieve now has an automatic controller with motorized regulating flap which monitors the under pressure in the sieving chamber and thus the dispersion effect of the nozzle jet and which keeps the under pressure constant throughout the entire sieving process.

FULLY AUTOMATIC SIEVE IDENTIFICATION Manual input of the sieve mesh width is no longer necessary, thus reliably preventing sieve insert errors.
This is particularly advantageous for laboratories in which a number of different products are analyzed with different sieve sets. Control via either the unit itself or by means of the LS-PRO software with stored database.

ULTRASOUND CLEANING CIRCULAR BATH MODEL TS-540
Standards: EN-196. ASTM C109,C184, C230 and C340
INTRODUCTION The cleaning principle by ultrasounds consists in the use of sound waves with higher frequecies than the human ear can detect, these go from 15 Hz to 20 kHz.
The generator of this bath produces sound vibrations in frequencies between 35 and 50 kHz, which are propagated inside the recipient mechanically, getting a sound resonance. The energy density for the acoustic field is so high producing a cavitation effect.
This effect consists in the formation of millions of low pressure microscopic bubbles (vacuum) which promote the cleaning of the surface immersed in the liquid in a molecular stage, taking the polluting impurities and dirt away from the parts or materials which must be cleaned.
The complex parts can be cleaned without be disassembled, as the cavitation penetrates in any place where the liquid remains in contact with the surface.
The “sandwich” type construction of the generator promotes a high efficiency degree for the ultrasounds waves, ensuring a heavy and uniform cavitation and minimizing the crepitation.

TESTING AREA DESCRIPTION
Compact design with one testing frame incorporated The machine is formed by one testing areas placed on the same frame. The hydraulic group and the control computer are located inside the frame, reducing laboratory space requirements.
The monitor, keyboard and printer (optional accessory) are installed on the worktop, at one side of the two testing areas.
COMPRESSION AREA
- Main columns. The tests frame has two columns made in chromium-plated and rectified bar
- Upper crosshead. The upper crosshead is to close the upper part of the testing frame providing a high level rigidity. In its lower part the load cell can be assembles together with the upper compression plate.
- Base plate. The group piston-sleeve is assembled in this piece. The lower plate is assembled over the piston as well as the waste collection tray resulting from the concrete compression tests.
- Piston-sleeve group. The piston finishing is chromium-plated/rectified. The water tightness on the sleeve is guaranteed through a high pressure and low friction joint.
- Compression plates. Two plates are available as compression elements, which are described below:
- Upper plate: The upper plate is assembled through turn on the load cell and will be the transmitter of the force to the mentioned transducer. It is made of hardened steel.
- Lower plate: The lower plate is assembled on the piston and is the one giving the force to the upper plate through the compression device.
- Waste-carrier. It is the dump which serves to collect the material waste once the compression process of a specimen is finished. This dump is placed in the lower part of the compression area, where you can enter through the frame’s frontal door. It is recommended to send to the back area the specimen’s rests with the help of a brush, so that they are poured through the hopper waste from the waste collecting tray to the waste-carrier.
- Protection against projections. The security device is formed by a rotatory transparent screen with an electric security closing, which forbids the equipment’s functioning if the protection screen is opened.
- End of stroke detector. As a security element the machine includes an end of stroke to avoid the piston going out of its guide in an excessive stroke.

- End of stroke detector. As a security element the machine includes an end of stroke to avoid the piston going out of its guide in an excessive stroke.
BENDING AREA
- Main columns. The tests frame has two columns made of chromium-plated and rectified bar. The
columns are threaded on their endings to fix them to the upper crosshead with two nuts and to the piston’s sleeve. - Upper crosshead. It is the closing device of the testing frame. The load cell is assembled in its lower part.
- Base plate. In this part is assembled the piston-sleeve group and it is fixed to the machine’s frame through Allen screws.
- Bending bridge. The bridge is assembled directly on the load piston and receives the force through it. It is formed by two rollers of 10mm diameter over which the specimen will be supported, and one top carpenter’s square to place the specimen such that it receives the load in its central part. The bending bridge includes an anti-rotation system, which centers it in relation to the piston.
- Piston-sleeve group. The piston’s function is to transfer the generated force to the specimen. The piston sleeve group is assembled over the base plate with three Allen screws. The piston is made of chromium-plated /rectified steel. The water tightness over the sleeve is guaranteed through a high pressure and low friction joint. The working pressure is of 250 bars.
- Load roller. The load roller is placed in the lower part of the load cell which is joined to the upper crosshead. This roller, the same as one of the support rollers, is articulated to allow a uniform load distribution on the specimen’s transversal section, without subjecting it to torque efforts.
- End of stroke detector. As a security element the machine includes an end of stroke to avoid the piston going out of its guide in an excessive stroke.
- Protection anti splashing. The safety device is composed by a Makrolon door with a safety electric close system, which avoids the machine to work if the anti splashing door is opened.
