As an important equipment for biomass energy processing, the design and performance of mobile diesel crusher must meet multiple industry standards to ensure the processing quality, efficiency and safety of biomass raw materials. The following is an explanation from three aspects: core standard requirements, equipment adaptability and advantages:
I. Core standard requirements for biomass energy processing
Biomass energy processing (such as straw, wood chips, agricultural and forestry waste, etc. converted into fuel or power generation raw materials) must meet the following key standards, and mobile diesel crushers must be adapted specifically:
(1) Raw material particle size standards
Different biomass utilization scenarios have different requirements for raw material particle size: when used for biomass pellet fuel, the raw material must be crushed to 3-5mm; when used as feed for biomass power generation boilers, the particle size is usually required to be ≤20mm.
The crusher must be equipped with an adjustable crushing gap or screens of different specifications to ensure that the output material particle size is uniform and meets downstream processing requirements.
(2) Raw material moisture content adaptation
Excessive moisture content of biomass raw materials (such as more than 30%) will affect the crushing efficiency and subsequent processing (such as drying and molding). Some standards require that the moisture content of raw materials before crushing must be controlled at 15%-25%.
Mobile crushers must have certain anti-clogging designs (such as wear-resistant blades and reversing functions) to meet the crushing needs of raw materials with medium moisture content.
(3) Safety and environmental protection standards
Equipment must comply with mechanical safety standards (such as guardrails and emergency stop devices) to avoid material splashing or operating accidents.
Diesel-powered equipment must meet exhaust emission requirements to reduce pollution to the surrounding environment; at the same time, it must be equipped with noise reduction devices to meet the noise limits of the workplace.
(4) Processing efficiency and stability
The crushing structure (such as hammer type, shear type) must be designed according to the characteristics of the raw materials (such as hardness and fiber content) to ensure crushing efficiency during continuous operation (usually requiring a processing capacity of 5-50 tons per hour, suitable for small and medium-sized biomass projects). The equipment must be wear-resistant, and key components (such as blades and hammers) must be made of high-strength alloys to reduce maintenance frequency.
II. Adaptable Design of Mobile Diesel Crusher
To meet the above standards, this type of equipment typically possesses the following features:
Mobility: A tire or track-mounted chassis allows direct access to agricultural and forestry sites, reducing raw material transportation costs and making it particularly suitable for on-site processing of dispersed biomass resources.
Power Adaptability: A high-torque diesel engine ensures stable operation in field environments without an external power source, adapting to varying processing capacity requirements.
Multifunctional Crushing System: By replacing the blades or adjusting the crushing chamber structure, it can process a variety of raw materials, such as straw, branches, bark, and rice husks, meeting processing standards for varying particle sizes and shapes.
Intelligent Control System: Some high-end equipment is equipped with material flow monitoring and overload protection to prevent damage caused by raw material impurities (such as rocks), ensuring operational safety. In summary, the mobile diesel crusher can effectively meet the standards of biomass energy processing in terms of particle size, efficiency, and environmental protection through targeted structural design and performance optimization. It is a key equipment for the development and utilization of dispersed biomass resources.
