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.

PELLETIZER DESCRIPTION

 SHALIMAR Engineering owing to rich industrial experience, we manufacturing and supply a quality tested assortment of Pelletizers. These products undergo strict quality checks before being introduced in the market. The offered products are made accordingly to meet the requirements of clients. Besides this, we ensure our prestigious clients to deliver these product in committed time frame.

The rotating pan is mounted on a tilting frame. Material is fed from above through a conveyor. Pelletizing liquid is sprayed through nozzles mounted on a movable manifold .Pellets are formed by the rolling motion of material in the pan and the liquid spray. Pellet size is determined by pan inclination, amount of liquid and other parameter. The rolling motion causes the larger pellets to rise to the surface and discharge continuously over the pan rim into a discharge chute.

Pelletizers can agglomerate fine, dry feed materials such as chemical powders, limestone, fertilizer, coal fines, cement / lime kiln dust and fly ash as well as wetter materials such as filter / centrifuge cake, minerals, ores, vibrating sludge and pond tailings.

1)   Fertilizer plant

WE Offer Trunk-Key plant NPK fertilizer plants, NPK plants, NPK mixture fertilizer plants and other fertilizer plant. We also have a formulation team by which we can also formulate any type of Fertilizer.

NPK mixture fertilizers are formulated & recommended by agricultural scientists to enhance the output of the crops by giving it specific and exclusive blend of plant nutrients. All the major plant nutrients like Nitrogen, Phosphorus Sulphur and Potash are mixed in different ratios to make it suitable for specific crops. These specific ratios of NPK & 8 are called grades. The numbers in the grade's name represents the percentage of N1, P2O5 & K2O respectively in the mixture. There are separate grades for Rice, Wheat, Potato and Sugarcane, etc.

NPK fertilizer plants are used for production of complex with different concentrations and types, such as inorganic fertilizers and biological fertilizers. These fertilizers can be obtained in the form of uniform granules from upto 4mm size. These granules are white, cream brown, gray or black in colour.

 

Process Design

The raw materials is in the weight belts conveyors are weighed in hopper and moved to grinding and then to mi Mixer for producing homogenous mixture. The material is mixed with the recycle material and taken for granulation in granulation drum where the partial granulation is achieved with very fine jet of water spray. The fine powder gets deposited on a small naclei. This process can be controlled to produce particle size as per the demand of the customers. The material is taken to dryer drum where hot air generated in the furnace is passed though it. The raw material having low melting points easily melts and gets deposited on the nuclei. The high temperature evaporates water and the material is air dried. Further, the material is cooled by blowing ambient air through it in cooler drum. The 1 - 4 mm or desired size homogenous particles are obtained using vibrating screens. The screened particles of uniform size are precisely packed in bag. The oversize material (after crushing) and undersize are recycled. The dust in the system can be separated with cyclones and scrubbed with water.

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   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.

Dry Mix mortar Making Plant

Shalimar Engineering is well recognized Manufactures, Exporter and Suppliers of various Adhesive Mortar Production Line plant & machinery. 

What is dry mortar:

Dry mortar is also called pre-mixed mortar, which made in the factory by precise batching and uniform mixing. It can be used directly just by adding water in construction site. It has different properties though adding different additives. The demand for dry mortar has increased rapidly due to its outstanding merit compare to the mortar production in job-site.

Description

It is use where high speed mixing process is required

1. Horizontal Plough Mixer consists of four parts: Transmission part, Agitator, Round Container, High-speed cutter. 
2. Two kinds of Transmission parts: Direct Connection type ( It can be installed as required to solve space problem.), Divided type (Chain driving and Belt driving).

3. The high-speed rotation coulter of the agitator disperse the materials from the axial direction, it also makes simple circle movement along the container.

4.The cutter in the mid rotates at a speed of 1440rpm to assist the materials mixing and agglomerate dispersing and depolymerization.
