BHOS High-Performance Hammer Mill Without Blower

Buschhoff hammer mills are renowned for their efficiency and ease of maintenance, with designs built upon over 40 years of accumulated experience. This extensive, decades-long know-how guarantees successful and reliable operation for your business.

Unlike conventional blower-equipped mills, the BHOS hammer mills, operating without a blower, achieve significantly higher grinding capacity at the same motor power output. This superior efficiency is due to the BHOS design, where 100% of the motor's power is dedicated exclusively to the milling process, eliminating any diversion of energy for material conveying.

Implementing the BHOS can lead to energy cost savings of up to 40% within your milling and mixing facility. This provides substantial benefits for both your operational budget and the environment.

The BHOS is available in two robust sizes, featuring powerful AC motors across a range from 11 kW to 110 kW. To ensure optimal and consistent performance, each hammer mill is equipped with either 24, 32, or 52 (depending on the model size) hard metal hammers. These hammers boast an impressive service life of at least 5,000 tons. Complementing this durability are our reinforced round-hole and mesh screens, engineered for similar exceptional longevity.

Hammer Mills type 150-300: Optimized for Smaller Livestock Operations

The BHOS 150-300 hammer mill series is specifically engineered for smaller animal farming facilities that demand efficient and dependable feed processing. These models deliver ample power and exceptional flexibility, positioning them as a prime choice for farms aiming to streamline their feed production without the need for extensive capital investment. Their space-saving design, coupled with compatibility for integration with screw conveyors or conveying spirals, ensures broad adaptability across diverse production requirements.

This advanced hammer mill brings distinct advantages to your processing workflow. It is powered by robust three-phase motors, available in the 11–22 kW range, guaranteeing consistent and optimal performance. A user-friendly quick-change mechanism allows for seamless transitions between perforated and wire mesh screens, providing unparalleled versatility to meet varied grinding specifications. Furthermore, the inclusion of reinforced hard metal hammers substantially extends maintenance intervals, significantly boosting the mill's reliability and longevity across a wide array of applications.

Industrial Hammer Mills BHOS 500 - 1200

The BHOS 500 – 1200 series industrial hammer mills, featuring power ratings from 37 kW to 90 kW, are engineered for exceptional durability and outstanding efficiency. These robust machines are capable of producing a wide array of feed textures while simultaneously delivering significant energy savings. This is achieved through a combination of their compact design, an exceptionally large screen surface, low-wear hard metal hammers, and a rapid screen-change system.

With an expansive screen area of either 0.65 m² or 1 m², these industrial mills are generously dimensioned per kilowatt of power. This thoughtful design ensures a consistent and uniform feed structure, even when operating at impressively high throughput volumes.

Every mill in this series can be optionally equipped with a frequency converter. This allows operators to precisely control the rotor speed, tailoring it to specific ingredient characteristics or recipe requirements, thereby ensuring the production of desired feed textures with optimal precision.

The resilient construction of these mills, including double-sided rotor bearings, a substantial number of reinforced hard metal hammers, and Buschhoff's extensive decades of experience in mill manufacturing, collectively establish these models as a true powerhouse, adept at meeting the most demanding grinding applications.

BHOS DUO Hammer Mills

The BHOS DUO system represents a cutting-edge solution for the efficient and economical processing of feed. It features two independent screens, significantly boosting both flexibility and throughput capacity. The reversible rotor rotation optimizes processing characteristics, while motor power ranging from 11 kW to 22 kW ensures robust and powerful operation.

Designed for maximum screen surface area, the system incorporates reinforced hard metal hammers, which provide an exceptional service life of approximately 15,000 tons. Users benefit from enhanced feed quality, as the unit can be precisely adapted to the specific requirements of various livestock species without the need for manual screen changes. This innovative design promotes superior efficiency and effectively addresses the diverse feeding needs within livestock management.

For the BHOS mill, we recommend an autofilter

When operating a milling system without a built-in blower, integrating an automated filter is highly recommended. The fully automatic Buschhoff auto-filter system is designed to handle three essential functions:

Efficient Material Extraction: It uses powerful suction to draw the processed grain out of the mill. This method significantly reduces the amount of fine dust and meal in the final product, ensuring a higher quality mix.
Optimal Cooling: The unit actively cools the milled grain immediately after processing. This crucial step protects valuable nutritional ingredients and prevents the buildup of harmful condensation.
Dust Prevention: By generating consistent negative pressure across the entire installation, the system effectively eliminates dust emissions, maintaining a clean and safe working environment.
