VI Series Vertical Shaft Impact Crusher. 1.The capacity is total tons per hour passing through crusher at open circuit when crushing medium and below hardness material and bulk density with 1.6x10³kg/m³.Capacities are relative to physical character and type of feeding,feeding size and composition and so on.
5. Material hardness. The reason for the material is that the material may be too hard or broken raw material is too large, beyond the maximum crushing range of impact crusher. The effective solution is that the crushing size should not exceed the prescribed range and hardness.
However, as crusher boards are easy to wear, there is a limitation to crush hard materials, PF series impact crusher is usually used for coarse and fine crushing of mediumhardness materials. The ideal feed size of PF impact crusher is 100500mm, the maximum sizes shall not exceed the specifiion.
Impact Crusher Working Principle Mineral Processing & Extractive Jun 23, 2015 An example of gravity impact would be dropping a rock onto a steel of a crusher is much helped by measuring the rock''s hardness during
Both the Impact Crusher and the Cone Crusher can be as secondary crushing equipment, but they crush different hardness materials. In general, the Cone Crusher mainly breaks some hard materials such as granite, basalt, tuff, etc., while the Impact Crusher is used to crush materials with less hardness, such as calcium carbonate and limestone.
Differences mainly in structural designs, crushing stages, working principles, performances, sides on environmental protection, finalsized products and product shape. Materials like granite, marble, etc. for impact rock crusher. Toohigh hardness materials like pebbles, limestone, basalt, iron ore, aluminum ore for fixed jaw crusher.
Working Principle Impact crusher is a crushing machine which uses the impact energy to break the material. When working, the rotor rotates at high speed driven by the motor, and when the material enters the crushing cavities, it will be broken into pieces with the plate hammer on the rotor and thrown on the impact liner to break again.
The paper presents the results of the testing of hardness impact on the stone fragmentation by hydraulic hammer and upon crushing in the laboratory crusher. Testing of Schmidt rebound hardness In order to test the impact of hardness on fragmentation of stone by hydraulic hammer and crushing in a jaw crusher
This series impact crusher can process the materials whose length of a side is below 100~500mm and maximum compression strength is 350Mpa, and it has the advantages of big crushing chamber and that the crushed materials are in the form of a cube so that it is suitable for crushing medium hard materials.

There are many factors affect impact crusher ability. the hardness of materials. The more hard material,the more difficult crushing up, but also for the equipment wear the more serious. The broken rate is slow, of course, crushing capacity is small.
There have been reported cases of the crusher jaw failure due to the high level of impact, tear and shear stresses experienced by the crusher jaw during service. The purpose of this paper is to select a suitable candidate material for the design of crusher jaw that can sustain fracture by any of the three modes of failure – tear, shear and impact at low cost using CES EduPack.
PFW European Type Impact Crusher European type impact crusher could process coarse, medium and fine crushing on materials with hardness below medium level, such as granite, barite, marble, limestone and so on. Mainly used in highway, railway, water conservancy, electric power, construction and other industries with sand and stone production.
The selection or sizing of a crusher is much helped by measuring the rock''s hardness during engineering. Impact Crusher Rock Particle Breakage in Impact Crushing Rapidly increasing operating costs for minerals beneficiating plants continue to be the biggest single problem in maximizing profitability from these operations.
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
Jaw Plate Material Selection. The impact of jaw plate wearable reason is mainly wearresistant material hardness and toughness. ① material is too hard, the material extrusion depth is shallow, the material deformation is small, the material for material shortrange sliding chisel cut is also small ② material toughness, resistance to fracture ability, can eliminate squeezing impact process
Vertical Shaft Impact Crusher Overview: Vertical shaft impact crusher is widely used in crushing and reshaping of rock and artificial sand making. It is suitable for crushing of fragile materials below level 9 of Moh''s hardness rather than viscous materials or stone materials containing much solid.
The impact crusher is widely used in railway, highway, energy, cement, chemical, construction and other industries. The size of the discharge material can be adjusted with diversified crushing specifiions. This series of impact crusher can process materials with side lengths of 100500 mm.
The majority of maintenance costs on an impact crusher comes from wear on the blow bars and aprons which if used to crush highly abrasive material, may surpass the initial cost of the cone crusher. As stated earlier, producers must understand their industry needs and the materials they will mine in order to choose the optimal crusher.
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.
