How a Reverse Screw Conveyor Makes the Maharaja-2 and Samrat 60 Zero-Handling Systems

The most expensive part of running a compost plant is not electricity or spares — it is people carrying material. Every time compost is shovelled from a bed into a barrow, wheeled to the machine and lifted again, you pay for labour and lose product to spillage. A reverse screw conveyor is the piece that removes one of those manual steps entirely, and it is why the Maharaja-2 and Samrat 60 can run as near-complete systems rather than standalone screens.

What a reverse screw conveyor does

When a screen separates fine compost from oversize, something has to happen to the oversize — the lumps, the not-yet-broken clods, the coarse fraction. On a plain screen a worker rakes it off and carries it back. A reverse screw conveyor instead carries that oversize back toward the grinder or the bed automatically, using an enclosed auger that handles moist, heavy material without spilling it. The tailings re-enter the cycle instead of piling up beside the machine.

The complete in–screen–out system

Because Anand Organics fabricates the machines and the conveyors in-house, they are built to work as one line. The Maharaja-2, for example, runs as a full system: an incline conveyor feeds material in, the machine grinds and screens in the middle, and finished compost comes out the other side — with almost no manual handling in between. The reverse screw closes the loop by returning oversize, so a single operator can keep the whole line fed and clear.

Labour and wastage saved

The payoff is steady output with fewer hands. Material moves at machine speed instead of shovel speed, the oversize never becomes a heap someone has to deal with later, and less compost is lost to repeated handling. On a plant sized for 40 to 60 quintals an hour, that difference in labour and lost product is what a conveyor pays back — usually far faster than its price suggests.

Which machines it fits

The reverse screw conveyor is matched to the larger machines in the range. The Maharaja-2 pairs with an 8 ft reverse screw conveyor; the Samrat 60 pairs with a 10 ft unit. Indicatively, reverse screw conveyors run from about ₹80,000 with a Maharaja to ₹1,00,000 with a Samrat, and are built to suit the machine and the plant layout. Prices exclude GST and transport.

Frequently asked questions

What is a reverse screw conveyor?

It is an enclosed auger conveyor that carries the oversize coming off a compost screen back toward the grinder or the bed, so the coarse fraction re-enters the cycle automatically instead of being raked off and carried by hand.

Can a conveyor be integrated with the screening machine?

Yes. Anand Organics builds machines and conveyors in-house, so conveyors feed directly into the screening machines. The Maharaja-2 runs as a complete system with an incline conveyor in, screening in the middle and finished compost out, with almost no manual handling.

How long is the reverse screw conveyor on the Maharaja-2 and Samrat 60?

The Maharaja-2 pairs with an 8 ft reverse screw conveyor and the Samrat 60 with a 10 ft unit. Indicative pricing is about Rs 80,000 with a Maharaja and Rs 1,00,000 with a Samrat, built to suit the machine and plant layout, excluding GST and transport.
