Description
System Overview
Which cow dung log machine is suitable for gaushalas in India?
Managing wet cow dung is a significant operational and environmental headache for gaushalas (cow shelters) and dairy farms. The Radha Solar Cow Dung Log Machine is specifically designed to meet this demand. It processes wet cow dung (moisture content 30-40%) blended with dry agricultural residues (wheat straw, sugarcane bagasse, or sawdust). The high-torque screw compresses the mixture through a heated die, melting the natural lignin in the biomass to form solid, dense logs without requiring any chemical binders. This machine is ideal for gaushalas looking to clean their premises while generating a highly profitable product.
Cost Savings, Profitability, and Government Grants
This machine offers a fast ROI of just 10 to 12 months. Cow dung logs are in massive demand by municipal crematoriums (which are actively mandated to adopt eco-friendly cremation logs) and local brick kilns. Under the GOBAR-Dhan scheme and various state-level animal husbandry grants, gaushalas and dairy entrepreneurs can secure capital subsidies covering up to 50% of the machinery cost. Additionally, being an MSME-approved product, banks offer collateral-free machinery loans.
Designed for Rugged Gaushala Environments
The machine is built using a reinforced steel chassis and a heavy-duty gearbox to handle continuous, multi-shift operations in harsh gaushala environments. It is highly resistant to corrosion from wet manure. During the hot Indian summers, the logs can be air-dried in open yards within 2 to 3 days. During the monsoon, the machine can be paired with Radha Solar Dryers to dry the logs in under 24 hours, ensuring year-round, uninterrupted production.

FAQ
Frequently Asked Questions
How do cow dung logs help in Hindu cremations (Shmashan Ghats)?
Traditional cremations in India consume about 350-400 kg of forest wood, causing significant deforestation. Cow dung logs (Gomaya wood) are a direct, culturally accepted substitute. They burn completely, generate minimal smoke, and one cremation using cow dung logs saves 2 to 3 fully grown trees.
What raw materials do I need to mix with the cow dung?
You use raw cow dung (30-40% moisture content). To improve the log's binding strength and increase its heat output, we recommend mixing in dry organic waste such as wheat husk, sawdust, sugarcane bagasse, or dry crop straw.
Can we get government grants for Gaushalas to buy this machine?
Yes. Gaushalas and dairy entrepreneurs are eligible for green technology grants, organic waste management subsidies, and animal husbandry grants from state governments in India.
Do I need to add chemical binders to make the logs?
No. The machine uses a heating element inside the die. This heat, combined with the extreme friction pressure of the screw, melts the natural lignin present in the cow dung and biomass, which binds the log naturally.
How long does it take for the logs to dry after extrusion?
In sunny weather, the logs dry in 2 to 3 days in the open air. If you use our Radha Solar Dryer, they can be dried and ready for sale in less than 24 hours.
What is the daily production capacity of the machine?
Our standard machine produces 500 kg to 1500 kg of logs per hour. In an 8-hour shift, a gaushala can easily manufacture 4 to 8 tons of logs.
Which cow dung log machine is suitable for a gaushala with 100 cows?
For a gaushala with 100 to 200 cows, our 7.5 HP model (500 kg/hr capacity) is the perfect fit. It is cost-effective, easy to run, and handles the daily dung yield efficiently.
Does the machine require three-phase electricity?
Yes. Because it uses heavy-duty industrial motors (7.5 HP to 15 HP) to compress the biomass, a three-phase power connection is required.
What is the lifespan of the extruder screw?
The screw is made of hardened alloy steel. Depending on the abrasive nature of your biomass mix (e.g., sand content), it will need refacing or replacement after processing 150 to 200 tons.
How much profit can a gaushala make from cow dung logs?
The raw material is virtually free. By selling logs to crematoriums or boilers at ₹6 to ₹8 per kg, a gaushala can generate a net profit of ₹2,000 to ₹4,000 per ton of logs produced.
Can the machine process wet cow dung directly?
No, the dung should not be slurry-like. The optimal moisture content is around 30% to 40%. If the dung is too wet, you must mix in dry straw, husk, or dry powdered dung first.
Are the logs water-resistant?
Once fully dried, the logs are dense and stable. However, they should be stored under a shed to protect them from direct monsoon rains, as moisture will soften them.
What diameter logs can the machine make?
We offer interchangeable dies of 50mm, 75mm, and 100mm. The 75mm (3-inch) and 100mm (4-inch) dies are the most popular sizes for cremations and industrial boilers.
How do cow dung logs perform in industrial boilers?
They have a calorific value of 3000 to 3500 kcal/kg. They burn steadily and leave behind clean ash that can be directly packaged and sold as organic fertilizer.
Does the machine make a lot of noise?
No. The heavy-duty gearbox ensures a smooth, low-noise operation, making it safe and comfortable for gaushala workers.
Is there any risk of fire inside the machine?
No. The heating element only warms the die to help form the log; it does not reach temperatures high enough to ignite the damp biomass inside the hopper.
Can we mix neem leaves into the logs?
Yes. Many gaushalas mix neem powder, camphor, or holy basil (tulsi) into the logs. This makes them highly popular for religious havan rituals and acts as a natural mosquito repellent.
Is the machine easy to clean?
Yes. The hopper is wide-mouth, and the screw can be reversed using the electrical panel to flush out any leftover material at the end of the shift.
What is the warranty period?
We provide a 1-year comprehensive warranty on the motor, gearbox, and electrical panel, alongside phone and onsite engineering support.
How many operators are required to run the machine?
Typically two operators: one to mix the materials and feed the hopper, and another to collect, cut, and stack the extruded logs on drying racks.
