Leading Manufacturer, Exporter and Supplier of 3 Roller Mill Plant, 3 Rollar Mill Manufacturer in India
Shalimar Engineering is a prominent manufacturer and supplier of three roller mills, also known as vertical roller mills, Raymond mills, dolomite grinding mills, manganese grinding mills, and coal grinding mills in India. With its state-of-the-art manufacturing facility located in South India, the company has been catering to the needs of customers in Odisha, Jharkhand and Madhya Pradesh, among other regions.
Three-roller mills are grinding mills with three horizontally positioned rollers rotating oppositely. The material to be ground is fed into the center of the top roller, which then passes through the gap between the other two rollers, undergoing a series of compressions and shearing forces that result in the desired particle size reduction. This design offers several advantages over other types of grinding mills, including higher efficiency, lower power consumption and better control over the product quality.
Shalimar Engineering has been in the business of manufacturing three roller mills for over a decade and has established a reputation for delivering high-quality, reliable and cost-effective solutions to its customers.

Operation
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
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.
Construction
the plows are cast out of Manganese Steel while the rollers and the bull ring are of Carbon See Casting. Classifier, Cyclone, Dust Collector, Blower, Ducting & supporting structure are made of Mild Steel Sheet a~z structural. Heavy duty Base Plate, Shell and Gear Box ar e made from Cast Iron and Mill Shell Body is single piece casting.

Salient Features
- SHALIMAR ROLLER MILL is designed in such a special way ensuring easy repair and maintenance. Easy access helps quick replacement of worn out parts.
- The Wear & Tear Cost per ton is Low.
- A (*) distance piece is provided between Gear box and Base Plate to prevent Dust Entry into the Gear Box. A fan is fitted on the Centre shaft which throws away the -particles coming out of the Centre Plate of the Base Plate. Thus a 100% Dust proof system ensures long life of the Bevel Gear, Pinion & V-Belt.
- Roller Arm Assembly incorporates a perfect Rubber seal to prevent the possible entry of the fine powder, which reduces easily wear & tear.
- Even a Semi-skilled person can operate the mill.
- The Worn-out parts can conveniently be replaced through an easily accessible service door
