The impact crusher is commonly used for the crushing of limestone, coal, calcium carbide, quartz, dolomite, iron pyrites, gypsum, and chemical raw materials of medium hardness. Effect of process conditions on the production capacity of crushed materials is listed in Table 8.10.
Suitable for softer, friable and non-abrasive materials. Ok for wet and sticky materials. Cone crusher and short head cone: feed diameter < 25 cm; reduction ratio 5:1 to 10:1 usually 7:1; capacity 5 to 300 kg/s: Mohs hardness < 8. Usually secondary or tertiary crusher. Impact crusher pulverizers, shredders or smooth roll: feed diameter 1 cm
Even ceramic and composite material hardness measurements are possible. The most commonly used scales are “B” and ”C”. In Rockwell hardness test, prior to applying the testing load, a small minor load is applied to seat the indenter into the test piece and remove the effect of any surface irregularities. This provides better accuracy.

Raw Material Properties. Different types of crushers have different working principles. The physical properties like hardness and fragility of raw material will all affect the crushing efficiency of a stone crusher. If we adopt the proper type of crusher to process proper raw material, the crushing efficiency of the crusher is high.
Impact crusher includes hammer and impact crusher, hammer crusher uses high-speed rotating hammer to strike, crushing and grinding, suitable for processing medium and soft hardness materials.
Impact Crusher Material Hardness. The hardness of crusher wear parts has a directly impact on crusher wear parts, such as cone crusher wear parts, jaw crusher wear parts.So it is necessary to have a detection on them before the crusher parts are delivered to customers.Here are some detection methods.
Bond impact crushability work index (CWi) (Bond, 1963) results reported for iron ores vary from hard iron ore (17.7 kWh/t) to medium hardness iron ore (11.3 kWh/t) and friable iron ore (6.3 kWh/t) (Table 2.11; Clout et al., 2007).

Impact strength – also called impact toughness – is the amount of energy that a material can withstand when the said load is suddenly applied to it. It may also be defined as the threshold of force per unit area before the material undergoes fracture [1]. The strength of materials may be defined in many ways, and some of the most common
Therefore, the materials used for the parts require higher hardness and higher toughness. When selecting the material of the jaw crusher parts, three factors must be fully considered: Impact load. Impact load is one of the important factors that should be considered in the rational selection of materials.
Roll crusher is suitable for medium and high hardness materials crushing in metallurgy industry, building materials and refractory materials industry. Features: 1. Reliable operation, good crushing effect. 2. Easy maintenance, ling service. 3. Low operation cost, resource saving. 4. Adjustable discharge size. Roll Crusher …:::The roller crusher has widely application in the industries of

Impact crushers make use of impact rather than compression to crush material. The material is contained within a cage, with openings of the desired size at the bottom, end, or side to allow crushed material to escape. There are two types of impact crushers namely (i) horizontal shaft impact crusher, and (ii) vertical shaft impact crusher.
impact crusher material hardness. The Complex Vertical Impact Crusher is fine crushing equipment that crushes materials in middle hardness such as rocks and mines with pressure strength less than 210MPa and humidity less than 5 Eg limestone dolomite cement clinker iron ore molybdenum ore aluminum cobble rock phosphorite copper ore burned magnesite serpentine calces gypsum lump coal zeolite
2 days ago· Introduction to compound cone crusher. The compound cone crusher is widely used in the metallurgical, building material, construction, chemical, silicate and other industries, which is suitable for crushing various ores and rocks with medium and above medium hardness. The compound cone crusher consists of standard type and short-head type.:::Impact crusher has a higher […]
Impact crusher blow bars material Different working conditions need to choose different types of blow bars, from high manganese steel, martensitic alloy steel to high-chromium iron. These types of blow bar can ensure that the impact crusher always maintains the best operating condition with the best cost performance.
technology, construction, working and maintenance of crushers for bulk materials is given in this article. Crushing Technology There are four basic ways to reduce size of a material: by impact, by compression, by shear or by attrition. Most crushers employ a combination of all these crushing methods. Impact

Dewo machinery can provides complete set of crushing and screening line, including Hydraulic Cone Crusher, Jaw Crusher, Impact Crusher, Vertical Shaft Impact Crusher (Sand Making Machine), fixed and movable rock crushing line, but also provides turnkey project for cement production line, ore beneficiation production line and drying production line.
Material QUALITY of Impact Crushers vs. Jaw Crushers. Quality is based on each client’s specific needs. The hardness of the finished, crushed product, depends on the hardness of the material being fed into the crusher. The gradation will be dramatically affected by the type of crusher used. The jaw crusher will generate less dust, less powder

In the context of mining and mineral processing, particularly mineral crushing, Teeri et al. (Ref 92) evaluated different powder-metallurgical steels and reference steels, and showed that the materials with the highest hardness do not display the best impact-abrasion wear performance.
The hardness of a material is a major consideration when selecting the type of crusher to use. Hardness is a factor in the amount of wear and tear crushers and screens experience. In most cases the hardest materials are: • Igneous formations (granite) • Metamorphic formations (quartzite) Softer materials are usually sedimentary formations
Crushing in Mineral Processing. In mineral processing or metallurgy, the first stage of comminution is crushing. Depending of the type of rock ( geometallurgy ) to be crushed, there are 2 largely different techniques at your disposition for crushing rocks. In principle, compression crushing is used on hard and abrasive rocks by placing them
PFS Strong Impact Crusher. PFS Strong Impact Crusher PFS strong Impact crusher can crush limestone, marble, granite, shale, coal, construction waste and other materials under medium hardness for medium and fine operations.This machine can directly crush the material less than 600mm, get the building aggregate less than 40mm which combines the primary and secondary crushing into one.
Smaller is the aggregate impact value, tougher is the material. This is because the fraction that passes through 2.83mm sieve is actually the crushed material that otherwise was a part of aggregate particle/s. More is the fraction finer than this sieve; less tough the material is.
Even ceramic and composite material hardness measurements are possible. The most commonly used scales are “B” and ”C”. In Rockwell hardness test, prior to applying the testing load, a small minor load is applied to seat the indenter into the test piece and remove the effect of any surface irregularities.
