Pelletizing Pin Mixer


Applying Industrial Experience to Agriculture

Mars Mineral is a leader in the design, manufacturing and servicing of manure pelletizing systems that help poultry farmers dispose of their animal waste in a manner that is environmentally safe and profitable. The systems include pin agglomerators, disc pelletizers or deep drum pelletizers.

For more than 40 years, the technology we are using to pelletize poultry manure has been employed primarily for agitation agglomeration -- the conversion of fine powders and dusts into spherical pellets. Over the past decade, we have established a presence in the poultry production market while continuing to serve customers in the steel, foundry, chemical, mining, cement, lime and fertilizer, and consumer products manufacturing sectors.

Our equipment and services are backed by solid experience, an engineering staff qualified in material handling, a veteran technical support group and in-house manufacturing expertise.

Regardless of your specific application, we have the experience to meet your needs while exceeding your expectations.

Mars Mineral is based in Mars, PA, about 20 miles north of Pittsburgh. The company is a division of Woodward Inc.

Why Pelletize

Turn Manure Into Money!

With federal Concentrated Animal Feeding Operations (CAFO) regulations in effect, the time is right for you to consider pelletizing your poultry waste and creating a new revenue source while complying with potentially burdensome government rules which are being updated continually.

Mars Mineral's Manure Pelletizing Systems give you everything necessary to make pellets for sale to fertilizer users such as agricultural production companies, independent farmers, golf courses and commercial landscapers, and "middle men" who deal with companies that use or sell fertilizer.

Our systems enable you to process from 500 to 50,000 tons (100 million pounds) of poultry waste annually.

The pelletizing process captures agriculturally valuable nutrients and minerals that originate from grain-based feed, along with organic material and humus to produce a certified organic fertilizer.

Pellets Made-To-Order

Mars Mineral is capable of designing customized manure pelletizing systems to almost any specification. Systems may include pin agglomerators, disc pelletizers or deep drum pelletizers.

The Gold Standard

Your Mars Mineral Manure Pelletizing System can enable you to generate significant new revenue from a waste material in five easy steps:

Pelletizing Advantages

  • Converts composted manure into a form that is safely, easily, and cost effectively packaged, transported , and distributed to soils in need of conditioning and natural nutrients.

  • Decreases the need for expensive, water-soluble, chemical-based fertilizers that may create harmful runoff into waterways and groundwater supplies.

  • Provides a beneficial soil amendment / conditioning aide for moisture retention and control – key to foster higher seed germination rates, plant growth, and yields.

  • Provides a totally safe growing medium that is environmentally friendly to people, pets, and the environment.

  • Provides an easy, cost effective means of combining composted manure with chemical fertilizers to create custom fertilizer blends.


Designing a Custom Chicken Manure Pelletizing System is a five-step process:







How a Typical Pelletizing Plant Works

Drying pellets

The Pin Mixer receives dried chicken manure from the storage bin and feeder, mixes it with binder, pelletizes and sends the pellets to the Dryer.

Drying pellets

The Dryer dries and cools the pellets, discharging them onto a conveyor belt that carries them to the Screen.

Drying pellets

The Screen removes and recycles oversized and undersized pellets, sending the “good” ones to the pellet storage bin, located outside the building.

Bagging pellets in 40 pound bags

The Bagger takes the pellets from the pellet storage bin and automatically fills a flexible intermediate bulk container (FIBC) or other package.

Wrapping pellets

The Palletizer & Stretch Wrapper arrange the filled bags on pallets, stacking them for shipment and stretch-wrapping them to the pallet for stability in transport.

With a Mars Mineral Pelletizing System, you’re helping to reduce environmental and public health problems by converting dusts, fines or powders into pellets which are easy to transport, re-use or store.

What You Should Know About Mars Mineral Manure Pelletizing Systems

What are the advantages of manure pelletizing?
Pelletizing poultry manure is an effective way for poultry growers to comply with new federal regulations that govern waste disposal in concentrated animal feeding operations (CAFOs). CAFO regulations became effective in 2006 and continue to be updated. These rules present an opportunity for pelletizing poultry waste and creating a new revenue source while complying with potentially burdensome government rules regulations.
What are some common applications for poultry manure?
Agricultural production companies, independent farmers, golf courses and commercial landscapers can use poultry manure as fertilizer, and do-it-yourself retail chains and lawn & garden stores can sell poultry manure to consumers who need fertilizer to help their plants, lawns and gardens grow lush without harming people, pets and waterways.
What is the chemical composition of poultry manure?
In general, poultry manure, after processing, consists of 4% nitrogen (N), 6% phosphorous (P), 4% potassium (K), and 86% organic material from dead plants and animals that will nurture the soil with optimal effectiveness.
How much room does a pelletizing plant require?
On average, a pelletizing plant is about 20,000 square feet.
What is the cost of a pelletizing plant?
The cost depends upon the plant's specifications. Mars Mineral provides customized solutions that precisely identify costs prior to plant construction.
How much does pelletized manure cost?
The retail price of a 1-1/2 pound jar is about $9.00, which translated to a retail price of about $12,000 per ton! Thus, the market opportunities are excellent.
How can I determine if my material is suitable for pelletizing?
Mars Mineral maintains a laboratory and pilot scale testing facility to process materials for determining the pelletability of your poultry manure.
How much poultry manure is produced in the United States each year?
In excess of 1 billion chickens are grown in the US annually. Each chicken generates about 4 lbs. of raw manure.
Why should I choose Mars Mineral to supply pelletizing equipment or systems?
Mars Mineral has been in the pelletizing equipment business for more than 40 years. During that time, we have supplied equipment and turnkey systems to the limestone industry. That experience and knowledge of limestone-related applications makes Mars the logical choice for meeting your pelletizing needs.
