400*1250 Crushing Mill Roll for Oilseeds Grinding Machine

Product Description

Oil seeds Cracking Mill Roller
Cracking rollers are the main components in oil seeds cracking mills. Oil seed cracking rollers are used to crack or crush oilseeds like soybeans, sunflower seeds, cotton seeds, etc. Oil seed cracking rollers are a key component in the oil seed processing industry.
The rollers consist of two corrugated or ribbed cylinders rotating in opposite directions with a very small clearance between them. The clearance, known as the cracking gap, is usually between 0.25-0.35 mm. As the oilseeds pass through this gap, they are cracked into smaller pieces and flattened.
Cracking the oilseeds achieves several purposes. It ruptures the cell structure of the seed to release the oil and improves the efficiency of extracting the oil. It also increases the surface area of the crushed seed for better oil release. The cracking rollers break the seed into uniform sized cracked pieces for efficient downstream separation of hulls and meats.
The rollers are typically made of cast iron and range from 12-54 inches long and 5-20 inches in diameter. They are mounted on bearings and driven by motors and gear systems at different speeds. Proper roller gap adjustment, seed feed rate, and roller corrugation pattern are necessary for optimal cracking. The rollers require routine maintenance and lubrication for smooth operation.

Advantages:
With over 30 years of history the cracking roller is the core product of our company.
Wear resistant: made of high quality nickel-chromium-molybdenum alloy by compound centrifugal casting to ensure durability under high pressure.
Low dust generation and high safety: Rollers produce less dust compared to impact or roll mill cracking methods. Less risk of dust explosions.
Energy efficiency: Corrugated surface to improve grip and feeding The continuous crushing action of the rollers requires less energy than impact crushing. Suitable for various oil seeds like soybeans, peanuts, cotton seeds, etc.
Simple maintenance: Rollers have relatively simple maintenance without complex parts prone to wear and failure.
Increased oil yield: Cracking the seeds ruptures the oil cells and exposes more surface area for extraction, improving oil recovery.
Competitive price: Adopted German casting technology, manufactured in China.
