PELLET MILLS
RICHI offers a full range of pellet processing equipment, covering animal and aquatic feed, biomass energy, organic fertilizer, cat litter, and other fields. The equipment is stable, efficient, robust, and durable, perfectly meeting various production needs.
Biomass Pellet
Machine Series
Biomass pellet mills can efficiently process various renewable biomass wastes, compressing them into high-density pellet fuel. Specifically, they can be divided into the following four categories:
●Wood Materials
Used for Bioheating
Primary raw materials include logs, branches and wood chips. Featuring high bulk density and compact fiber structure, wood-based materials produce pellets with high calorific value and remain the mainstream feedstock in the global biomass pellet market.
●Crop Stalk Materials
As a Clean Energy Source
Agricultural residues such as corn stalks, wheat straw and rice straw are lightweight, bulky with long fibers and high toughness, requiring primary crushing prior to pelleting. Stalk pelleting effectively curbs air pollution caused by open-air burning.
●Rice Husk Materials
Waste Recycling
As a by-product of rice processing, rice husk features low raw material cost and acts as a vital supplementary feedstock for regional biofuel production. Pre-treatment or blending with wood meal and stalk powder is commonly required before pelleting.
●Alfalfa Materials
Used for Ruminant Feed
Our equipment can process high-protein, high-fiber forage such as alfalfa and oat grass into high-density pellets, which can be used as high-quality biomass fuel or as high-nutrition feed pellets for ruminants.
Feed Pellet
Machine Series
Depending on the specific livestock being raised and the characteristics of the raw materials used, they are primarily applied in the following four major fields:
●Livestock Feed
Suitable for both sows and piglets
Designed for the omnivorous nature and stage-specific nutritional needs, our pellet mills allow flexible adjustment of pellet diameter and hardness. They process a wide range of feedstocks including grains, meat and vegetable residues, promoting voluntary feed intake and healthy weight gain.
●Poultry Feed
Chickens, Ducks, and Geese
With robust feedstock processing capability and flexible custom-engineered design, our mills efficiently produce premium-quality pellets or mash feed in multiple sizes. Generated feed improves palatability, effectively eliminates feed selectivity, and enhances poultry digestibility and nutrient absorption.
●Ruminant Feed
Camels, Cattle, and Horses
Ruminants have specific requirements for feed hardness, fiber content, and nutritional composition. To address this, our machines are equipped with forced feeders and single-stage extended conditioners, ensuring stable production of high-quality pellets even from lightweight feedstocks such as grass meal.
●hay pellet
alfalfa, grass and straw
Forage has high fiber content and low bulk density, making it prone to clogging. Our pellet mill is equipped with an arch-breaking feeder and a forced feeder, along with a high-torque motor, which can stably compress forage pellets. An optional conditioner can also be used to soften the fibers.
Fertilizer Pellet
Machine Series
RICHI organic fertilizer granulators are ideal equipment for creating green, efficient, and sustainable organic fertilizers. The raw materials for their granulation are widely available and can be broadly categorized into the following four types:
●Animal Manure
Soil Fertility Restoration
Through fermentation and granulation, manure resources are transformed into odorless, easy-to-store, and convenient-to-apply granular fertilizer, which helps farms utilize manure resources while retaining the organic matter and nutrients in the manure.
●Organic Waste
Crop Fertilization
Complex raw materials such as kitchen waste, food residues, and landscaping trimmings can be processed into granular organic fertilizer or biomass fuel, effectively reducing the environmental pressure from landfilling and incineration of organic waste.
●Compost
Garden Maintenance
Compost is a stable organic material produced through aerobic fermentation, rich in humus and trace elements. After processing, it can be used for fruit trees and landscaping, effectively increasing its added value and enabling commercial operation.
●NPK
Animal Pen Bedding
A compound granular fertilizer made from urea, potassium sulfate, and other raw materials, with uniform nutrients and resistance to clumping, suitable for mechanized application, effectively improving fertilizer utilization and crop yield.
Aquatic Feed
Extruder Series
Aquafeed extruders are the cornerstone of modern aquafeed processing, widely utilized in the production of fish feed, shrimp feed, pet food, and raw material extrusion applications.
●Fish Feed
Floating Feed
Our extruders are suitable for freshwater and marine fish such as grass carp, carp and grouper. They can produce floating, slow-sinking and sinking feeds to match feeding habits of fish at different water depths, cutting feed waste and maximizing aquaculture profits.
●Shrimp Feed
Sinking Feed
Traditionally, shrimp feed is produced by pellet mills. As demand for better palatability rises, high-end producers adopt extruders to make slow-sinking feed. Extruders are now gaining growing market share in the shrimp feed industry.
●Pet Food
Slow-sinking Feed
Suitable for manufacturing complete feed lines for dogs, cats, hamsters, and all other pets. We offer custom-engineered solutions for pellet shape, size, and nutritional composition to meet the specific taste and digestive requirements of different animals.
●Raw Material Extrusion
Functional Feed
Used for the gelatinization and extrusion processing of raw materials including corn, soybeans and wheat, improving digestibility and safety. Extruded raw materials can be used as feed bases, pet food ingredients, or raw materials for the food industry.

Frequently Asked Questions
The following is a summary of frequently asked questions regarding configuration, installation, after-sales service, pricing, and complete plant setup, to help you quickly understand RICHI products.
What role does the conditioner play in the feed production process?
The main function of a conditioning machine is to heat and condition the material before pelleting, so that the material fully absorbs heat, moisture and liquid, so that the starch paste, to achieve or close to the requirements of the pelleting process.
What are the core components? How is quality ensured?
Key components feature Siemens motors and SKF bearings. All product-contact parts, including feeder, conditioner, and ring die, are 304 stainless steel. The ring die undergoes vacuum heat treatment; rollers are made of 42CrMo alloy steel. The control cabinet supports independent operation, enabling isolated shutdown for maintenance without disrupting the full line.
Are wood pellet mills and stalk pellet mills interchangeable?
They can be used interchangeably in general scenarios, yet with significant output discrepancies. Due to distinct physical properties, dedicated stalk/forage pellet mills (CZLH Series) deliver 50%-100% higher output than wood pellet mills (MZLH Series) under the same power rating. We strongly recommend selecting a dedicated model according to your primary raw material for optimal return on investment.
Can organic fertilizer pellet mills produce both pellet fertilizer and powder fertilizer?
Yes, achievable by adjusting production workflow.For powdered organic fertilizer: Fermented and crushed materials bypass the pellet mill and directly enter screening and packaging, while the pellet mill can remain standby for pellet production.For pellet organic fertilizer: Activate the pellet mill; materials go through pelleting, drying, cooling and screening before final packaging.
What are the advantages of twin-screw extruders over traditional single-screw floating extruders?
Twin-screw extruders are high-performance machines capable of producing both floating and sinking feeds. They feature two intermeshing, co-rotating screws inside the barrel, with a complex structure and high precision. Compared to traditional single-screw floating extruders, they offer superior shearing and mixing capabilities, enabling efficient processing of high-fat, high-moisture, high-fiber, and low-starch formulations.
What is the minimum requirement to start a commercial animal feed production project with RICHI?
We only focus on large-scale farming animal feed projects and commercial feed production projects. If you are looking for a small machine to produce your own animal feed at home, we are not the right choice – we would rather tell you upfront to save your time.Our configuration include small-scale equipment for crushing, mixing, granulating, etc. If you are unsure of your specific requirements, just send us your basic requirements.
