Sometimes the terms "coarse" (or UNC/Unified Coarse Thread) or "fine" (UNF/Unified Fine Thread) are used to describe the thread. The term does not refer to the quality of the thread but rather to the frequency of threads per inch. "Fine" has more threads per inch than "coarse".
smaller sized coarse aggregate produces higher strengths for a given water-to-cement ratio. In fact, it is generally agreed that, although larger coarse aggregates can be used to make high-strength concrete, it is easier to do so with coarse aggregates below 12.5 mm (Y, in.) (ACI 363-95).

Impact Impact refers to the sharp, instantaneous collision of one moving object against another. During the collision, both the objects may be moving, such as a cricket bat hitting a fast moving ball, or only one object may be moving, such as a rock being struck by hammer blows. There are two types of impact: gravity impact and dynamic impact.
Primary and secondary stages involve crushing of coarse materials while the tertiary and quaternary stages involve the reduction of ore particles to finer degrees. Activities at the primary stage will depend on gyratory, jaw or impact crushers. Cone crushers, roll crushers and impact crushers are mostly used at the secondary stages.
The discharge granularity is different.Counter-crushing with some micro-shaping effects, the material produced is sharp and angular, and the grain shape is good, which is also determined by the working principle of the impact crusher; the cone crushing is divided into coarse, medium, fine, superfine, etc.Model, the broken material is finer and ...

Investigating Coarse Aggregate Impact on Concrete Shrinkage While most bridge decks in Arkansas perform adequately over their design life, early-age shrinkage cracking is a recurring issue in some bridges that can lead to compromised durability. Shrinkage cracks may lead to serious deterioration such as rebar corrosion and freezing and thawing.
crusher's discharge gap, because the production continues through an on-line coarse size analysis of the crushed product (digital image analyses). Dance, A. 2001) More attention is being paid to the impact on crushing circuit style caused by variations in ore characteristics, size distribution, moisture content, ore grade and climatic conditions.
This is a new type of cone crusher, adopting the whole hydraulic operation, is easy to operate. Owing to the use of better crushing frequency and eccentric distance, the percentage of fine graininess is much higher, and the content rate of the granularity smaller than the discharge opening on closing edge may reach 80%.As a result of handling capacity of following operating procedures is ...
The impact absorbed energy of two pass thermal simulation samples at different T p2 conditions is shown in Fig. 4. The average impact absorbed energy is 26.6, 29.1, 46.5, 81.5 and 12.1J at T p2 of 150, 600, 800, 1000 and 1300 °C, respectively. The hardness is 273, 226, 220 217, and 231HV, respectively.
This steep decrements in impact toughness are attributed to the formation of coarse PAGs, fine bainitic ferrite, and martensite with hard and coarse M/A islands (Figs 3, 4, 5). An improved impact toughness in the CGHAZ sub-regions was measured due to relief in the thermal stresses (b/w T 2p 600 ºC to Ac 1 ) and reconstruct microstructure at ...
