MBI Primary Crusher

Speed-Valve Technology

Speed-Valve Technology is an advanced feature, designed to significantly enhance the attachment’s efficiency and productivity. This innovative hydraulic valve system optimises the flow of the hydraulic fluid within the attachment. This reduces the time taken for the jaws to open and close during demolition tasks. 

This technology maintains smoother operation and minimises delays allowing for more jobs to be completed in a shorter period of time. Increased productivity and cost-effectiveness on the worksite are a major benefit of the Speed-Valve Technology. The improved fluid dynamics within the hydraulic system also helps reduce stress on the components, prolonging the attachments lifespan.

4-Sided Cutting Edges

Unlike conventional cutting edges that require replacement when they are worn out, our MBI Primary Crusher has 4-sides edges that can be rotated and reused, effectively quadrupling the service life of the product.This will not only reduce the frequency of blade replacements, but also ensures the crusher continues to maintain optimal performance for longer periods of times.This feature also minimises the downtime associated with maintenance and blade replacement. This increases overall operational efficiency and productivity. By using all four sides of the cutting edges, there is also more uniform wear and tear, allowing for consistent performance throughout their lifespan.This innovation is particularly beneficial in operations which require the crusher to be subject to constant and intense use.

Specific Tooth Profile

The tooth profile on the MBI Primary Crusher has been specifically designed and engineered to maximise the crushing efficiency and effectiveness. Each tooth is shaped to maintain optimal material engagement, enhancing the crusher’s ability to break down tough materials efficiently.This increases the crushing process, resulting in finer and more consistent material output. This profile of the teeth also reduces strain on the crusher, helping to evenly distribute the forces involved when crushing. The improved performance when crushing also reduces the risk of damage to the equipment, prolonging the life of the equipment.The specific tooth profile is particularly beneficial when processing heterogeneous materials, as it ensures efficient crushing regardless of the material's size or hardness, making the crusher highly versatile and adaptable to various industrial needs.
