Analysis of the application and development of ash spreader technology

I. Industry Overview

Ash spreader is a special equipment used to evenly distribute lime, cement and other stabilized soil materials in road engineering. It is widely used in the construction of bases such as highways and airport runways. Its core function is to achieve material metering and paving through a precise control system, improve construction efficiency and reduce manual errors.

II. Technical classification and principle

Mechanical spreader

Adopts a spiral distributor or belt conveyor structure, suitable for large-particle materials, low cost but poor accuracy.

Hydraulic spreader

The spreading roller is driven by a hydraulic motor, and the flow valve is adjusted to control the material thickness, with an accuracy of ±5%.

Intelligent spreader

Integrated GPS and sensors, real-time monitoring of paving thickness and automatic adjustment, such as German VOGELE brand products.

 
III. Key performance indicators

Spreading width: common 3~6 meters, expandable to 12 meters (large projects);

Work efficiency: 200~400 tons of material are processed per hour;

Environmental protection: The closed design reduces dust pollution and meets the National IV emission standards.

IV. Application scenarios and cases

Highway construction: used for water-stabilizing layer construction, such as the Beijing-Shanghai Expressway expansion project;

Soil improvement: improve acidic soil in the agricultural field and spread lime powder.
