Rice Mill Jali (Sieve/Screen)

The “jali” in a rice mill, often translated as sieve or screen, is a perforated metal sheet that is fundamental to the rice milling process. Its primary function is to separate rice grains from husks, bran, and broken grains during various stages of milling.

Function:

• Husk Separation: In the initial de-hulling stage, jali with larger perforations allows the husked rice to pass through while retaining the larger unhusked paddy or husks.
• Bran Removal/Polishing: During the polishing stage, the rice grains rub against each other and the emery roller within a chamber enclosed by jali. The fine perforations of the jali allow the bran particles to be sieved out, resulting in polished white rice.
• Grading and Separation: After polishing, different jali sizes are used in grading machines to separate whole rice grains from various grades of broken rice, immature grains, and other impurities. The mesh size of the jali directly determines the fineness of separation.

Importance:

• Quality Control: The correct mesh size and quality of jali ensure consistent rice quality and purity.
• Efficiency: High-quality jali prevents clogging and ensures efficient separation, leading to higher output.
• Reduced Waste: Proper jali selection minimizes the loss of good rice grains with waste products.
• Material: Often made from durable materials like mild steel or stainless steel to withstand constant abrasion.

Pulverizer Jali (Sieve/Screen)

When a rice mill is combined with a pulverizer (for grinding grains into flour), the pulverizer section also uses specific jali. This “pulverizer jali” is distinct from the rice milling jali and is designed for fineness control during grinding.

Function:

• Particle Size Control: The pulverizer jali features very fine perforations that determine the ultimate fineness of the flour or powder produced. As the grinding mechanism (like hammers or discs) pulverizes the material, only particles smaller than the jali’s holes can pass through.
• Separation: It prevents larger, un-ground particles from exiting the pulverizer, sending them back for further grinding until they reach the desired fineness.

Importance:

• Product Consistency: Ensures uniform flour texture, crucial for baking, cooking, and various food applications.
• Efficiency of Grinding: Selecting the right jali optimizes the pulverization process, preventing over-grinding or under-grinding.
• Versatility: Different pulverizer jali sizes allow the same machine to produce various grades of flour (e.g., coarse meal for animal feed, fine flour for human consumption).
• Material: Typically made of robust mild steel or stainless steel to endure the abrasive action of grinding.

Pulverizer Roll (Grinding Roll/Rotor)

In a pulverizer, especially disc mills or those with grinding surfaces, the “pulverizer roll” refers to the grinding element that crushes and grinds the material. While hammer mills use hammers, other pulverizers, like disc mills, utilize rotating elements or stationary/counter-rotating rolls for grinding.

Function:

• Crushing and Grinding: The pulverizer roll, often a rotating disc with serrated edges or a cylindrical roller, works in conjunction with a stationary plate or another rotating element to crush and grind the material fed into the pulverizer.
• Friction and Impact: It applies mechanical force, through compression, impact, shearing, or attrition, to break down raw materials (like grains, spices, or herbs) into smaller particles.
• Material Introduction: The design of the roll facilitates the continuous feeding and processing of the material.

Importance:

• Grinding Efficiency: The design, material, and speed of the pulverizer roll directly impact how effectively and quickly materials are ground.
• Particle Size Reduction: It is the core component responsible for the actual size reduction of the material.
• Durability: Given the abrasive nature of grinding, pulverizer rolls are made from hardened, wear-resistant alloys to ensure a long operational life.
• Product Quality: The quality of the roll and its interaction with other grinding surfaces influence the uniformity and texture of the final powder.

These components are consumables and require periodic replacement to maintain the efficiency and output quality of rice mills and pulverizers.
