Center Sizer – High Efficiency in Primary and Secondary Crushing

Precision and Power with the Center Sizer
The MCI Center Sizer is your go-to solution for primary and secondary crushing, delivering a precisely defined product size with minimal oversize content. It crushes material between the teeth in the middle of the chamber using a combination of shear and tensile forces. This method ensures efficient reduction of feed sizes up to 2,000 mm with throughput rates reaching up to 9,000 tph.

Key Features

Optimized Crushing Ratio: Achieve a crushing ratio between 3:1 and 6:1, tailored to your specific needs.

High strength Bullet Teeth: Hard material crushing, easy maintenance and long durability with well proven hight strength bullet teeth alloy.

Low and easy Maintenance: The robust design and easy replaceable bullet teeth with high-quality materials ensure long service life with minimal maintenance requirements.

Minimal Fines and Dust: The low circumferential speed of the rolls reduces fines and dust, resulting in a cleaner final product.

Flexibility for Secondary and Tertiary Crushing

Adaptable Crushing Solutions with the Side Sizer
For secondary and tertiary crushing, the MCI Side Sizer offers unmatched flexibility and precision. It crushes material between the longitudinally arranged teeth and adjustable crushing combs, providing a clearly defined product size with the ability to handle feed sizes up to 800 mm.

Key Features

Precise Product Sizing: Achieve a final grain size of up to 30 mm with adjustable crushing combs that allow for a flexible range in the final product size.

Low Fines Content: Similar to the Center Sizer, the Side Sizer’s design minimizes fines and dust in the end product, enhancing overall product quality.

Replaceable Crushing Components: Easily replaceable toothed segments and combs are designed for quick maintenance, reducing downtime and ensuring long-term operation.

Side sizer principle for secondary and tertiary crushing

Optimized Crushing Ratio: The Side Sizer can achieve a crushing ratio between 2:1 and 3:1, depending on the application, with throughput rates of up to 2,500 tph.

Durable and Efficient Design: Like the Center Sizer, the Side Sizer is constructed from materials chosen for their durability, ensuring the longest possible service life while maintaining low operational costs.

Advanced Drive Systems: The Side Sizer’s drive system can be customized with either electrical or hydraulic options, depending on the specific requirements of your operation.

Enhanced Flexibility: The adjustability of the crushing combs allows the Side Sizer to adapt to varying material types and sizes, making it a versatile choice for complex crushing needs.
