Jaw crusher BIZON-450 with gasoline engine

Bizon-450-S is the most efficient jaw crusher in the series, designed for effective crushing of large construction materials such as stone, concrete, brick, and rubble with a strength of up to 320 MPa. Thanks to its large feed opening, it can crush pieces up to 450 mm in size, making this model perfect for recycling and construction industry applications. The Bizon-450 model is also available in an electric version, allowing for quieter operation without exhaust emissions.

Unlike the smaller models in the BIZON series, this jaw crusher allows processing of stone with a larger fraction (up to 450 mm in length and up to 250 mm in height and width).

To obtain a fraction below 10 mm, we recommend setting two jaw crushers in a single technological line — the larger crusher pre-crushes the material to a 50–80 mm fraction, and the smaller one then grinds it down to the required, fine fraction.

Operating principle

The jaw crusher is powered by a motor of your choice — it can be either a gasoline or an electric motor. The moving plate/jaw moves up and down via an eccentric shaft. The angle and distance between the fixed plate/jaw and the moving one become smaller as the moving plate descends — this is when the material is crushed into pieces. The distance increases as the moving jaw rises. When the moving plate is pulled away from the stationary one by springs, the crushed particles exit the working area.

The key working elements of the crusher - the jaws - are available in several material variants, selected depending on the type of material being processed. In the standard version, included in the set, the jaws are made of EN-GJL-250 grey cast iron. Optionally, jaws made of Mn18Cr2 high-manganese steel and Hardox steel are also available. These materials are characterized by high resistance to wear and impact loads.

For crushing softer materials, such as brick or ceramics, the use of grey cast iron jaws is recommended. For hard materials, such as fieldstone or granite, jaws made of Mn18Cr2 high-manganese steel or Hardox steel are recommended.

The crusher's working section is available in two versions, selected depending on the type of material being processed:

• The standard version, included in the set, allows adjustment of the output material fraction. It is primarily intended for crushing softer materials, such as brick, concrete or ceramics.
• For working with the hardest materials, such as granite or fieldstone, a second variant is available - the reinforced working section. This design has been developed for crushing hard materials and intensive operation. When ordering the machine with the reinforced working section, the use of jaws made of Hardox steel or Mn18Cr2 high-manganese steel is recommended, as they provide increased resistance to wear and impact loads.

When the reinforced working section is used, the output fraction cannot be adjusted. The output fraction has a fixed value of 30 mm. The design has been developed to minimize the number of moving components, resulting in high equipment reliability.

Applications

The Bizon-450-S is a universal concrete crusher, stone crusher, rubble crusher or even a brick crusher. Its simple design enables easy operation and use in a wide variety of conditions. It is perfect for recycling, road construction, the chemical industry, and mining. The gasoline-powered version is ideal for worksites without access to electricity, where high performance combined with mobility is required.
