Rock drilling machinery and pneumatic tools

The small diameter front wheel drives the steering wheel.
The larger diameter rear wheels are the rollers.
The engine is equipped with a relatively high-powered internal combustion engine and a hydraulic plate for compaction of the extruded material.
The width of the curved flat blade is also in addition to the width of the chain scraper conveyor and the propeller type vibrating roller.
The apparatus for extracting substances from a mixture is specialized, and a patented apparatus is used for extracting a viscous sample from a mixture, for example, from an asphalt material.
The device consists of a sieve member for screening the sample.
A solvent supply system and a discharge member for removing the analyzed material.
The structural features of the device ensure the minimum consumption of solvent.
The feed member is formed as a solvent feed sprayer having a rotary spray head or a fixed spray nozzle type.
Fig. Asphalt Pavement Adhesive Layer Reinforced with woven mesh. The German patented honeycomb woven mesh is mainly used for the reinforcement of asphalt road surface layer.
The net is formed by weaving the polymerized or heterocyclic compound fiber strands that can bear load in a crosswise and crosswise manner, and is glued or welded in sections and coated with attachments having a chemical bondability to the asphalt.
Woven nets have good adhesion properties and are a non-woven, thin material.
