ASHOKA is a one stop shop for the cement and mineral plants supplying individual equipment as well as complete production lines. We have managed to build a brand as a manufacturer and exporter of equipment designed to life long performances at lowest maintenance levels and least down times. We are a brand that builds equipment most suitably adjusted to customer requirements.

Ashoka an ISO 9001:2008 company, undertakes its production activities from two self sufficient units located outside the national capital New Delhi covering approximately 120,000 sq. feet of covered area with further expansion plans underway. The company comprises of a dedicated and talented team of over 200 skilled professionals including engineers, design draftsmen, management experts and certified machinists.

At Ashoka, our vision is to integrate, to provide ‘total solution’ to our customer. We firmly believe that one needs holistic approach in order to exceed. We have well anticipated the diverse and growing needs of our customer and become a total solution provider. We have emerged as a single window for all major activities relating to setting up a cement and mineral processing plants including-

• Conducting site surveys for site selection
• Raw materials (limestone) testing and suitability analysis
• Preparation of detailed project reports
• Basic and detailed plant engineering and design
• Manufacturing of process machinery
• Manufacturing and supply of factory sheds and steel structures
• Selection and procurement of bought outs
• Project planning and scheduling
• Civil works designing and drawing development
• Equipment inspections and CIF dispatch to international destinations
• Supervision of Erection and commissioning of plant machinery supplied by us
• On site training of plant personnel.

We undertake contracts on EPC basis in order to be the one stop shop for our customer. Works and services are outsourced to extremely experienced experts in the respective activity whether it be process design and engineering or on site services.

The range and capacity of projects undertakern by us includes:

• Vertical shaft kiln cement plants- 50TPD to 300TPD
• Rotary kiln cement plants- 300TPD to 2000TPD
• Clinker grinding units- 100TPD to 2500TPD
• Lime plants
• Grinding units for special minerals such as - Feldspar, dolomite, slag based minerals, quarts etc.

Ashoka manufactures horizontal cylindrical shaped drums and mills for grinding of minerals, scrubbing, drying, cooling etc. We can manufacture drums upto 5.0 m diameter and 15.0 m length. 

The grinding operation is generally achieved through motorized rotation of the cylinder with steel balls or ceramic pebbles freely rotating onto the material being ground. that causes balls to fall back into the cylinder and onto

These mills are divided into multiple chambers along its length with the chambers further divided by diaphragms.

ROTARY DRYERS AND COOLERS 

Rotary Dryer/Coolers are used for drying/cooling of reasonably free flowing materials through the introduction of drying/cooling media subjected directly onto the material being processed. The material which needs to be processed enters through one end of the rotating drum and is puched along the length of the drum through a sequence of inner fins/lifters that are fixed on the interior wall of the drum. 

We can offer these dryers with the option of customization in different configuration and specifications.

Working Principle of Direct heaters/coolers:

• Material that requires being dried/cooled comes in direct contact with drying/cooling medium.
• Here, Drying/Cooling media is admitted through stationary inlet hood at one end and is discharged from stationary discharge hood at another end.
• Feed admitted through suitable feeding mechanism like screw feeder/simple chute.
• Rotating shell provided with the specially designed material showerings mechanism like lifters and others.
• Shell inclination & rotating speed allow forward movement of material towards discharge end, thus offering required residence time.
• Drying (or Cooling) is done through heat transfer to/from showering material with drying/cooling media within a shell.
• Product discharged from stationary hood using suitable equipment like rotary valve/ flap valve/screw conveyor/chute among others.

Working Principle of Indirect heaters/coolers:

• Material which needs to be dried does not come in direct contact with dry media.
• Dryer comprises assembly featuring two concentric rotating shells that come supported on rollers & tire stations and driven through suitable drive arrangement.
• Feed admitted through suitable feeding mechanism including screw feeder/flap valve into dryer through stationary inlet feed hood.
• Specially designed return gas passages on the inside of the outer shell that allows drying media admitted through the inner shell to travel towards discharge end & again return towards feed end.
• Inner shell provided with suitable radial lifters.
• Drying takes place through heat transfer to showering material by direct contact with inner shell & return passages.

General Features:

• Dryers/coolers come steel fabricated and are supported by solid steel columns and beams/rollers and tire arrangement.
• Rotating shell driven through suitable drive arrangement which comprises girth gear and pinion driven through gear reducer and coupled to the motor of suitable rating.
• Also provided with separate pollution control equipment installed alongside dryers.
• Firing arrangement makes use of different fuel forms including liquid, gaseous and solid fuels.
