The Machine Structure of Lab Jaw Crusher:
This series of jaw crusher is composed of machine body, eccentric shaft, belt pulley, fly wheel, movable jaw, side guard, gap adjustment screw, return spring, fixed jaw plate and movable jaw plate. This series of crusher have: high crushing ratio, regular finished product size, simple structure, reliable operation, easy to maintain and other characteristics.
Lab Jaw Crusher Operating Principle:
For this crusher, crushing way is squeeze-press type, motor drive belt and belt pulley, through eccentric shaft to make movable jaw move up and down. When the movable jaw rises, the angle between toggle plate and movable jaw plate will become large, so that moving the movable jaw plate closed to the fixed jaw plate, meanwhile the material is pressed, rubbed, grinded for many times. When the movable jaw plate down, the angle between toggle plate and the movable jaw plate will become small, with the effect of spring, the movable jaw plate will leave fixed jaw plate, at this time, the crushed material has be discharged out from the crushing chamber. With the motor continuous rotation, the movable jaw plate will make a periodic crushing and discharging to realize continuous crushing.
The Laboratory Davis Magnetic Tube Tester consists of an extremely powerful electromagnet which can generate a magnetic field intensity of up to 4,000 gauss, a glass separation tube and a motor driven agitation mechanism. The tube is positioned between the poles of the magnet at an angle of approximately 45 degrees (the angle is adjustable). During the operation of a small electric motor drives the agitating mechanism that supports the water filled glass tube. The tube moves forward and backward while it rotates simultaneously. Any magnetic particles present in the product sample inside the tube are collected in the zone of intense magnetism. A vigorous washing action by agitation is applied to these magnetic particles. Eventually all non magnetic particles are flushed from the tube. A clean concentrate of magnetic particles is then available for determining percent.
The Laboratory Vibrating cup mill operates on the principle that the grinding set is fixed on a freely vibrating structure and the grinding media (the disc and the ring(s)) inside the grinding set are accelerated by centrifugal force. The sample material is ground by a combination of impact and friction forces, which depending on the material can reduce the particle size down to 10-20µm. Additional Information:
Applications: laboratory testing of particle size and size distribution in samples of solid materials
Laboratory Ro-Tap Sieve Shaker are used for laboratory testing of particle size and size distribution in samples of solid materials. Used for soils, geological materials, alloys, and a host of other solid sample types that have individual particle sizes of from over 5" down to 20 microns. Testing is accomplished by stacking a set of sieves of various sizes on top of each other, where the larger-hole sieves are on top and smaller-hole sieves are on bottom, in decreasing order. A solid pan is at the bottom to catch all sample particles that can pass through the smallest sieve's openings. The ro-tap sieve shaker is an apparatus that holds the entire stack of testing sieves, mechanically shaking / rotating them in a circular motion and tapping the top of the stack at the same time (this, rotap). These actions help the various sized particles to be able to move through the stack of sieves until they rest on a sieve whose openings are too small for them to pass through. After a designated period of time of this mechanical shaking/tapping, the screens are removed from the ro-tap, and each sieves contents are weighed up and recorded individually, from this data set, the % retained on each sieve is used to classify the size fractions present in the sample.
The materials of construction of grinding media depends up on the type of samples to be grind for geological ores & minerals - hardened steel grinding media, for alloys - tungsten carbide lined grinding media for coal & coke - tungsten carbide coated grinding media.

Hydro cyclone has no moving parts. It consists of a conically shaped vessel, open at the bottom, variously called the underflow, apex or spigot, and connected to a cylindrical section which has a tangential feed inlet. The top of the cylindrical section is closed with a plate through which passes an axially mounted overflow pipe. The pipe is extended on to the body is the cyclone by a short, removable section known as vertex finder, which prevents short- circulation of feed directly into the overflow.
Hydro cyclone Test Rig is designed for laboratory testing of classifying various solids in a slurry. It is equipped with a Hydro cyclone, a sump a slurry pump with a internal piping and valves to circulate the slurry through the cyclone from the sump or to re-circulate the slurry, and a pressure gauge to monitor the pressure drop across the cyclone. All equipment is conveniently mounted on floor or steel frame.
Jigging is the process of separating the particles of different specific gravity, size and shape by introducing them on screen though which a fluid is made to pulsate alternately. It is consists of a rectangular open top container. The bottom of the container is either a screen or a perforated surface which supports the bed of the solids. Pulsion and suction strocks of water through the screen are given by means of a reciprocating piston. During the pulsion stroke, solid bed is opened and the particles are lifted. The particles settle into more homogeneous layer during the suction stroke. By repeated pulsoin and suction stroke, a complete stratification is achieved with the heavy particles at the bottom and lighter particles above them.
The following three effects contributes to the stratification in Jig:-
Hindered settling classification.
Differential acceleration at the beginning of fall.
Principle: Wilfley table is most widely used shaking table.
It consists of a slightly inclined deck on to which feed, about 25% solids by weight, is introduced at the feed box and is distributed along the feed launder, washes water is distributed along the balance length of the feed launder.
The table is given shaking motion longitudinally using a slow forward stoke and a rapid return, which causes the mineral particles to move along the deck parallel to the direction of motion.
In this table, the riffles run parallel with the long axis and are tapered from the maximum height on the feed side till they die out near the opposite side, parts of which is left smooth.
Where the riffles stand high, a certain amount of eddying movement occurs, aiding the stratification and jigging action between the riffles.
As a load of material is jerked across the table, the uppermost layer is swept or rolled over into the
In this way, the uppermost layer of sand repeatedly moves over to riffle after riffle after riffle until it leaves the deck.

Laboratory Electro Wet Magnetic Drum Separator (Wet Process):
When a stream of ore particles is continuously passed through a field of magnetic force, the magnetic particles are attracted towards the source of magnetic force while the non-magnetics travel unaffected. The processing materials enter the top of the magnetic drum separator and flows across the surface of the drum. The rotating drum in the magnetic field captures the ferrous tramps whereas non ferrous falls free from the drum into the cleaned material flow. As the drum rotates, the ferrous metal so captured is carried past the diverted and released outside of the magnetic field.
Laboratory Electro Magnetic Drum Separator(Dry Process):
Description: Electro Magnetic Drum Separator consists of a rotating non-magnetic drum containing electromagnet. Magnetic particles are attracted by the magnets, pinned to the drum, conveyed out of the field and discharged while the non-magnetic particles are discharged unaffected. The magnetic drum is fed at the top vertical centre, but, with appropriate magnet positioning, it can be fed at any convenient point or even front fed or underfed.

The laboratory rod mill is a rotating drum that causes friction and attrition between steel rods and ore particles. But note that the term 'rod mill' is also used as a synonym for a slitting mill, which makes rods of iron or other metal. Rod mills are less common than ball mills for grinding minerals.The rods used in the mill, usually a high-carbon steel, can vary in both the length and the diameter. However, the smaller the rods, the larger is the total surface area and hence, the greater the grinding efficiency.
