Engineering Machine

We have wide ranges of engineering machine and these machines are appreciated by our clients i.e. Briquetting Machine, Paper Mill Machinery and Spares, Sugar Mill Machinery and Spares and Biomass Briquette.

Biomass Briquette

Biomass Briquettes are made from the Agricultural waste, Forest Waste and Industrial Waste. It is converted into solid cylindrical shape. The major residues are Rice Husk, Coffee Husk, Coir Pitch, Jute Sticks, Sugarcane Bagasse, Groundnut Shell, Mustard Stalks, Cotton Stalks, Sawdust, Castor Seed Shells / Stalk, Wood Chips, Bamboo Dust, Tobacco Waste, Tea Waste, Paddy Straw, Wheat Straw, Sunflower Stalk, Palm Husk, Soya Bean Husk, Veneer Residues, Barks and Straws, Forestry waste, Seeds Cases etc., Briquettes are the only Binding. Biomass briquettes are eco-friendly renewable source of energy and avoid adding fossil carbon to the atmosphere.

A number of companies in India have switched from furnace oil to biomass briquettes to save costs on boiler fuels. The use of biomass briquettes is predominant in the southern parts of India, where coal and furnace oil are being replaced by biomass briquettes. A number of units in North India are also using biomass briquettes as boiler fuel. Use of biomass briquettes can earn Carbon Credits for reducing emissions in the atmosphere. Biomass briquettes also provide more calorific value/kg and save around 30-40 percent of boiler fuel costs.

Bio-mass briquette is one which takes a waste products such as saw dust, compresses it and then extrudes it to make a reconstituted log which can replace firewood. It is a very similar process to forming a wood pellet but on a larger scale. There are no binders involved in this process. The natural lignin in the wood binds the particles of wood together to form a solid. Burning a wood briquette is far more efficient than burning firewood. Moisture content of a briquette can be as low as 4%, where as green firewood may be as high as 65%.

Raw Materials Used

  • Groundnut Shell
  • Saw Dust
  • Coir Pith
  • Sugarcane Bagasse
  • Coffee Husk
  • Tobacco stems
  • Charcoal Powder


Depending upon the customer's requirement of using Raw materials and availability, it can be tried and presented. The above material can be individually Briquettes or in mixed form also.
Products and its Advantage.

Fuel Briquettes are used to replace conventional fuels like coal, firewood in heating and steam generation etc., Briquettes have the advantage of having high risk calorific value ranging 3500-5000 K Cal. Kg depending upon the raw material used.

Briquettes do not emit smoke with sulfur or phosphorus and also fly ash. Hence no need of pollution control equipments. Briquette fuel is sized 80 mm in diameter and 50-350 mm in length screw type and 45-60 mm in diameter in ram type to get complete combustion.

Easy handling, storage and transportation as the briquettes are uniform in diameter and can also be packed in bags.
Briquette fuels, as it is made out of Agro waste can be made easily available and there is an advantage of bulky garbage reused with high fuel efficiency.

Sawdust Drying Machines

Drying is significant for the good preparation of resources previous to their briquettes. To build superior quality briquettes with high mass, it is very vital to manage the wetness content of the raw stuff to 8-12% before loading them into briquette machine, so sawdust and other kinds of biomass want to be dried first.

Operation principle:
 The entire systems consist of fan blower, motor engine, fuel boiler, steel pipe, cyclone and air lock.
In this structure, wet objects is input into the hopper by screw feeder; Fuel boiler produces large amount of hot air, that hot air is motivated into steel pipes, varied with wet sawdust and moved through twist pipes and ventilation chamber by the power of fan blower. Fast moving hot air sustains and is mixed with raw material sent by twisting feeder in the suspending state through the steel pipe; moisture evaporates as the material traverses along the steel pipe and is rendered dry at the discharge end. Humid air is continuously exhausted, thus the material is dried. The air lock in the outlet stops the hot air to be exhausted to the atmosphere, but release the dried material via cyclone.

Typical Applications:
Ultimate for subtraction of moisture from free of charge smooth materials which is light and tiny like sawdust, rice shell, milled stalks etc., suitable for small production scale below 700 kgs per hour.

It is suitable for drying materials of moisture 30-35%. It takes the advantages of low cost consumption and high efficiency, reducing the moisture to 8-12%. Wet material is input into the hopper.The stoves (boilers) generate hot air which mixes with wet materials and then is sucked into the pipes by the exhaust blower (fan) quickly. And then hot air are flowing and going though the curving pipes and buffer (drying chamber) of dryer, thus wet materials is finished to dry, and the dried materials are discharged from the outlet with air lock.

Technical data :

Consumption of Waste 70 Kgs.


Briquetting Machine

Briquetting is a process of fuel manufacturing system from Agro waste like groundnut shell, cashew nut shell, saw dust , coir pith, coffee husk, cotton stalk etc.

The best and chief process found in experience is manufacturing briquettes from a mixture of 80% saw dust and 20% groundnut shell. In other cases like 100% groundnut shell briquettes, pulverized is to be done which increases the production cost.

Marketing :

The marketing potentially is very high in tea estates, Tyre retreading units,Bricks Kiln,Textiles processing units etc.The ideal and viable and users now are Tea estates and Tyre units because they will consume large quantity.

Working Method :

The Briquetting Plant consists of

  • Feeding system with screw conveyor
  • lubrication system
  • Cooling line &
  • Electrical

The above system is a semi automotive one with less labour.

The Briquetting Press is the main machine forming solid bio-Fuel briquettes from loose Agro wastes. The press consists of main the body called Skeleton fabricated from 30 mm steel plates.The approximate weight is 1.50 M.T. The other parts are two casting fly wheels each weights 900.

Production Cost Per Ton :

  • Average Material Cost  2300/-
  • Die spares : 120/-
  • Labour Cost : 200/-
  • Current : 200/-
  • Gunny Bags : 50/-
  • Administration : 100/-
  • Oil and Etc : 15/-
  • PB Bush : 15/-

Maintenance :

  • Change the spares like Taper Die , Split Die , Ram in 160 Hrs. and 40 Hrs. Once change the wear ring.
  • Change oil (ALFA ZN 220) in 2000 Hrs. (40 Lts.) C. Change the all Phosphor Bronze bush in 5000 Hrs.

The machine capacity is 1.5 Ton/Hour. If the machine run 10 Hour per day the production is 1.5 tons and for 20 hours 30 tons/day. The cost of machine will be Rs. 13 lacs. Building required with roof 100 sq. feet open area for sundry 4000 sq.feet. Raw materials storage & finished goods stock area are to be provided.
