40 [%] Grade according High, F 150 High, F 150 to frost resistance Grade according M 1200 M 1000 to crushability
Hardness in 6/7 -- 10-point scale [points] Grade according High, ST-1 High, ST-1 to abradability Strength at 7.
After analysis of numerous laboratory tests (made by Road Research Laboratory of the Vilnius Gediminas Technical University, SE "Problematika" and JSC "Laboratorinitj bandyrruj centras" laboratories) evaluating key material properties of dolomite and gravel chips, it was found that gravel chips gave better results in: Crushability
Index SR8/12, the Polished Stone Value (PSV), amount of particles of P form, adhesion to bitumen (%), with the amount of "Wetfix", adhesion to bituminous emulsion, frost resistance; dolomite chips presented better results in: Flakiness Index Msk, resistance to fragmentation by the LA test method, resistance to fragmentation by the impact test method (SZ), losses in the mass of particles after 10 freezing and thawing cycles (F50, F100).
It also allows us to get better control over crushability
Each has four infeeds and 61 delivery chutes which can cater for all shapes and sizes, packaging and crushability
The layer ratio changes from 90% HDPE in the neck, which requires stiffness to withstand capping, to 90% mLLDPE in the body, which makes it soft for squeezability and crushability
Firstly the system is capable of adapting the crusher's operating parameters to changes in moisture content, crushability
and wear characteristics of the feed material.
