3 ROLLER MILL

INTRODUCTION

Material to be ground is fed to the grinding chamber through star feeder. The positioning of the ploughs ensures that the material continuously passes between the rotating rollers and the stationary bull ring and as such this brings about grinding process. The ground material is swept by the ascending stream of air and carried to the classifier. Over sized particles are returned by the classifier to the grinding chamber for regrinding. The desired product is carried to the cyclone. The final product is collected at the bottom of the Cyclone while the Air having fine dust is discharged from the Top of the Cyclone and the Dust laden air goes to the Dust Collection Unit where the dust is separated and clean Air is discharged in the Atmosphere

Staying tuned up with time and technology for over 25 years, LEW aspires to give our customers best solution, better products and services. We strive hard to contribute substantially to the global priority areas of energy conservation and environment protection. For saving energy and achieving good quality products, we have developed a THREE ROLLER MILL and a CLASSIFIER for it which ensures consistent output upto 400 Mesh.

PRINCIPLE

Material is ground by pressure & friction between stationary bull ring and the rotating rollers, which swing outwards due to the centrifugal force 

DESIGN.

·         MILL

The mill foundation houses the drive pull which incorporates a thrust bearing to support the central shaft and endures the roller loads. The grinding rollers are hinged on the spider. The roller assembly is uniquely designed to prevent the possible entry of fine powder. A perfect ball bearing with neoprene rubber seal is incorporated to prevent the entry of dust to the roller arm assembly. The contact area between roller arms and bull ring is maintained in such a way to achieve uniform and gradual wear & tear of the Roller. 

·         CLASSIFIER

The Classifier helps to obtain any mesh size upto 400 mesh by increasing or decreasing the RPM of the Whizzer Classifier through a Variable Speed Drive Motor. A knob is provided to adjust the required mesh. This helps in saving a lot of Time, Money & Energy. A Gear Box is mounted in the Classifier driven by 5 HP Electric Motor which is designed in such a way to prevent entry of the dust in the Gear Box.

·         BLOWER

The Fan casing is made from 5 mm M.S. Plate and suitable base is mounted with casing for the Electric Motor arc bearing Housing. The Base is made from 8 mm thick plate The M.S Fabricated Impeller is fitted on the shaft and shaft is mounted with Mono Plumber block and bearings. The blower is driven through a V-belt transmission with the help of Electric Motor.

APPLICATIONS

Ultrafine Air Classifying Mills are used for size reduction of various products to microfine particle sizes. The system incorporates integral classifier where the fine particles of desired size are segregated and the over size particles back to the grinding chamber and re-grinded until the desired particle size is obtained. Air Classifying Mill is very compact and efficient, having sharp classifier cut points which are instantly adjustable. The system incorporates grinding and classification in one single compact space saving design.

SALIENT FEATURES :

o   Grinding and Classifying in one machine

o   Cool and smooth grinding

o   Steep particle size distribution

o   Sharp Classifier cut point, instantly adjustable.

o   Easy cleaning and maintenance.

o   Low specific energy requirement

o   Compact space saving design.

operating..PRINCIPLE:
The material to be ground is conveyed from a hopper by screw feeder or pneumatically fed through Rotary Air Lock Feeder to the grinding chamber of the Air Classifying Mill (ACM). The pins/bars of the rotor break the particles of the material. These particles are entrained by an air stream which enters below the pin rotor and are carried up between the inner wall and the shroud ring with baffles which decrease the air swirl. These particle then enter the classifying section where the fine material is carried out with the air through the classifier rotor to the outlet, the course material is thrown against the shroud rind and carried down to the pin rotor for further reduction. After leaving the micronizer air mixed with fine particles enter the bag filter where the fine particles are separated and the clean air is discharged to the atmosphere.

Microniz Air Classifier

Our Micronizing plant consists = feed hopper with screw feeder, Ultra fine air classifier ,,inter-connecting Ducts, Dust Collector (Bag Filter), Blower, Air Compressor and  Electric Control Panel with Electric Motors.

OPERATION: This unit has specially been designed to serve the purpose of classification of the ground material. The mineral powder of 400/500 mesh size is feed to the hopper through screw feeder which further leads to the classifier unit which classifies the powder in the  order of 20 or 10 micron size and the coarse material (i.e. Tailing) is recovered from the  bottom of the Air lock. The classifier runs through ‘V’ Belts drive with the help of Electric Motor. The RPM of the classifier is adjusted through variable frequency drive in order to obtain different microne sizes. The Blower Placed in the circuit pushes the material to the classifier unit for classification of the  material as per requirement and then the same goes to the RPJ Dust Collector from where the final product is collector through Air Lock. It is a Continuous process wherein we feed new material with tailing material through screw feeder.

ABOUT GYRO SCREEN (vibro shifter)
New technology shifter is giving horizontal, vertical and circular mechanical vibration. Vibro Shifter is for screening dry powder OR wet medium. It is also useful for separation solid-solid OR Solid-liquid and classification of solid. It is rigid screening device, which vibrates with screen above its center of mass. Whole mass is suspended on coil springs, which gives thrust to screening unit by its own compression and de-compression. Spring allow unit to vibrates freely and also prevent transmission of vibration on floor. Number of screen decks and spacing frame assembled on circular base frame. Screen is uniformly tensioned in all direction by center support. Specially designed vibrating motor generates vibration. Eccentric shaft is fixed on both side extended motor shaft. Eccentric weight is rotate with motor and generates vibration of whole masks.

HOW GYRO SCREEN (vibro shifter) WORKS
Material for screening is to be fed into upper screen deck. Fine material enter into lower deck after pass from top screen and coarser remain over screen. Material over each deck is automatically discharge from individual discharge spout. Over size material discharge rate can be increase by increasing horizontal throw. Horizontal throw is increase by rotation of upper eccentric mass. Maximum vertical vibration is desirable for clean the screen and dislodge material. Vertical and tangential plane vibration is change by lower weight. Angular position of upper and lower eccentric weight is for control circular motion of particles in the screen for getting better screening efficiency.
