What Is a Nut Flour Grinder Machine and How Does It Work?
The machine works by feeding nuts into a hopper. The nuts then pass through a set of precision-engineered roller mills or grinding discs. The rollers crush and shear the nuts at high speed, turning them into uniform powder. The grinding fineness is controlled by adjusting the gap between the rollers — the smaller the gap, the finer the output.
Key working principle: Roller compression + shear force → continuous grinding → adjustable mesh output → fine, uniform nut flour.
Types of Nut Flour Grinder Machines: Which One Is Right for You?
Not all nut flour grinders are the same. Jiangsu Hongda Powder Equipment Co., Ltd. manufactures the YGJ Series Roller Mill, which comes in four main types based on grinding fineness and multiple sizes based on production capacity.
1. YGJ1 Series — Coarse Nut Flour Grinder (8–20 Mesh)
Best for coarse grinding applications. Ideal for producing chunky nut meal or pre-crushing before further processing. Low power consumption and compact size.2. YGJ2 Series — Medium Nut Flour Grinder (8–40 Mesh)
A popular choice for standard nut flour production. This type is widely used in sesame milling machines, groundnut crushers, and almond flour machines. Balances output quality and energy efficiency.3. YGJ3 Series — Fine Nut Flour Grinder (8–60 Mesh)
Delivers fine powder output. Suitable for food manufacturers who require smooth texture nut flour for baking, confectionery, or health food production.4. YGJ4 Series — Ultra-Fine Nut Flour Grinder (8–80 Mesh)
The finest grinding available in the YGJ series. This machine produces silky, ultra-fine nut powder. It is the preferred choice for high-end food processing, pharmaceutical applications, and premium product lines.Each series is available in four size variants — 100, 150, 300, and 500 — representing the roller diameter in millimeters and directly affecting production capacity.
Key Parts of a Nut Flour Grinder Machine Explained
Understanding the key components of a nut crushing machine helps you evaluate quality and make the right purchase.• Feeding Hopper: Evenly distributes raw nuts into the grinding chamber for consistent input.
• Roller Mills (Hobs): The heart of the machine. Three sets of roller hobs — two for chopping, one for fine grinding. Made from high-grade hardened steel for durability.
• Adjustable Gap System: Controls the distance between rollers to set grinding fineness from 8 to 80 mesh.
• Drive Motor: Powers the rollers. Ranges from 0.75 kW to 11 kW depending on model and capacity.
• Stainless Steel Frame: Food-grade stainless steel construction ensures hygiene and corrosion resistance.
• Discharge Outlet: Collects finished nut flour after grinding, ready for packaging or further processing.
What Nuts Can Be Ground into Flour? (Almond, Peanut, Walnut & More)
The YGJ Series nut flour grinder from Hongda is designed specifically for oily materials. It handles a wide variety of nuts and seeds without oil separation, sticking, or oxidation issues — a common problem with standard crushers.• Peanuts (Groundnuts): The most common application. The machine produces uniform peanut powder with no oil leakage.
• Almonds: Produces fine almond flour at 8–80 mesh, ideal for baking and health food industries.
• Sesame Seeds: Specially suited for sesame grinding. Output is uniform and fine, with no stickiness — a key advantage of the YGJ roller design.
• Soybeans: Common in food manufacturing. The machine handles large continuous batches.
• Walnuts: Ground into walnut flour for bakery and confectionery use.
• Coffee Beans: Roasted coffee beans are easily processed by this dry nuts grinder.
• Cocoa Beans: Used in chocolate and food processing industries.
• Rapeseed: Processed for oil extraction and food manufacturing.
This makes it a truly versatile roasted nuts grinder, dry nuts grinder, and sesame seed grinder machine all in one platform.
Understanding Mesh Size: How Fine Can a Nut Flour Grinder Go?
Mesh size is one of the most important specifications when buying a nut flour grinder machine. It directly determines the particle size of your finished product.Here is a simple breakdown:
• 8–20 Mesh: Coarse — crumbly texture, visible granules. Suitable for nut toppings or animal feed.
• 8–40 Mesh: Medium — similar to coarse breadcrumbs. Used in standard food manufacturing.
• 8–60 Mesh: Fine — smooth flour texture. Ideal for baking, confectionery, and beverages.
• 8–80 Mesh: Ultra-fine — silky powder. Used in premium food products and health supplements.
With the YGJ Series roller mill grinder, operators can adjust the gap between rollers to achieve the exact fineness required — without stopping production. This flexibility gives food manufacturers complete control over product quality.

Stainless Steel vs Other Materials: Why Food-Grade Matters
When buying a nut grinding machine, the construction material is not just about durability — it is about food safety and international compliance.Hongda's YGJ Series is built from food-grade stainless steel. Here is why that matters:
• No Rust or Corrosion: Stainless steel resists moisture and oils naturally present in nuts, extending machine lifespan.
• Hygienic Surface: Smooth stainless steel surfaces are easy to clean and prevent bacterial growth — essential for food manufacturing.
• International Compliance: Food-grade materials meet export standards for markets in Europe, the USA, Southeast Asia, and beyond.
• No Contamination: Unlike carbon steel or plastic components, stainless steel does not react with food materials.
If a manufacturer offers a peanut grinder for sale or almond crusher made from non-food-grade materials, walk away. It will create compliance problems in export markets.
How to Adjust Grinding Fineness on a Nut Flour Grinder Machine
One of the most practical advantages of the YGJ Series nut flour grinder is its simple, tool-free adjustment system.Step-by-step adjustment process:
• Step 1 — Start the machine and allow it to reach full operating speed.
• Step 2 — Feed a small test batch of nuts into the hopper.
• Step 3 — Collect the output and check the fineness using a test screen or visual inspection.
• Step 4 — Turn the adjustment knob to reduce the gap between rollers for finer output, or increase the gap for coarser output.
• Step 5 — Run another test batch and repeat until you reach the desired mesh size.
This process takes just a few minutes and requires no special tools or technical expertise — making the machine extremely easy to operate, even for new staff.
Industrial Nut Flour Grinder vs Commercial Nut Flour Grinder: Key Differences
Many buyers confuse industrial and commercial nut flour grinders. Here is a clear comparison to help you choose:
| Feature | Industrial | Commercial |
| Capacity | 100–1000 kg/h | 20–80 kg/h |
| Power | 5.5–11 kW | 0.75–3 kW |
| Best For | Factories & export | Small shops & labs |
| Mesh Range | 8–80 mesh | 8–60 mesh |
| Machine Size | Large footprint | Compact |
Hongda manufactures both types under the YGJ Series, allowing buyers to select the exact configuration that matches their production volume and budget.
