High Energy Efficiency and Low Operation Cost

The energy conversion efficiency of the motor reaches over 80% (fuel engines are about 30%-40%). Under the same crushing volume, power consumption is much lower than fuel consumption, saving 30%-50% of energy costs in the long term.

There is no need to frequently replace fuel engine consumables such as engine oil and filters. Maintenance items are simplified (only regular inspections of the motor, bearings, and hydraulic system are required), reducing maintenance costs by more than 40%.

Low Noise Operation and Friendly Working Environment

The noise of the motor operation is usually below 85 decibels (fuel engines can reach over 100 decibels). With the design of a soundproof cover, it can meet the noise restriction requirements for urban night construction and operations around schools/hospitals, reducing disturbance disputes.

Intelligent Control and Simple Operation/Maintenance

Integrated with a PLC control system, it supports remote operation and automatic adjustment of crushing parameters (such as rotation speed and feeding amount), which can optimize crushing efficiency in real-time according to material hardness, reducing manual operation difficulty.

The modular structure design (such as detachable crushing chambers and one-key lubrication systems) allows for quick positioning of faulty components during maintenance, shortening maintenance time by more than 50%.  Strong Crushing Performance and Wide Adaptability

Equipped with high-torque motors and wear-resistant alloy crushing chambers, it can crush rocks with a compressive strength ≤300MPa (such as granite and basalt). The finished product has uniform particle size (0-40mm adjustable), meeting the material requirements of different engineering projects.

It supports various crushing processes (such as jaw crushing, cone crushing, and impact crushing), and can flexibly switch modes according to material characteristics. Its application scenarios cover mines, construction, environmental protection, and other fields.

II. Typical Application Scenarios

Urban Construction Waste Treatment and Recycling

- Scenario: Crushing and recycling of concrete blocks and bricks in old urban area renovation and road renovation, converting construction waste into recycled aggregates (used for subgrade filling and environmental brick production).

- Advantages: Low pollution and low noise characteristics avoid affecting surrounding residents. Electric drive is convenient for connecting to urban power grids without fuel transportation, suitable for operations in dense urban areas.

Green Mining in Mines and Quarries

- Scenario: Primary crushing of ores in open-pit mines and rock crushing operations in underground mines, especially suitable for mines around ecological protection areas and water sources to meet environmental protection mining requirements.

- Advantages: No exhaust emissions, reducing mine dust and air pollution; explosion-proof motor design (some models) can be used in high-risk environments such as gas mines, with higher safety than fuel equipment.

Highway and Railway Engineering Construction

- Scenario: Rock crushing in subgrade construction, crushing treatment of tunnel excavation debris, and processing production of railway ballast (crushed stone).

- Advantages: Can be connected to temporary power grids at construction sites to reduce transportation costs of fuel equipment; intelligent control ensures uniform crushing particle size, meeting the standards of road base materials.

Environmental Protection Projects and Tailings Treatment

- Scenario: Crushing and screening of tailings sand and smelting waste, converting industrial solid waste into building materials (such as non-fired bricks and concrete admixtures).

- Advantages: Low energy consumption by electric drive, and with a dust removal system, it can control dust diffusion during waste crushing, complying with the harmless treatment requirements of environmental protection projects.

Emergency Rescue and Special Scenario Operations

- Scenario: Debris clearance after disasters such as earthquakes and mudslides, requiring rapid crushing of concrete obstacles; or operations in flammable and explosive areas (such as around chemical plants).

- Advantages: No open flame and low noise, avoiding secondary disasters; some models support vehicle-mounted mobile power supply, adapting to field environments without power grids.

Small-Scale Building Material Processing and Rural Infrastructure

- Scenario: Rural road construction, crushed stone production in small mixing plants, and processing of sand and gravel for rural self-built houses.

- Advantages: Compact equipment size (some small electric crushers occupy
