Operational factors. The way how you run your impact crusher affects your wear life greatly. Fines management: the more fines entering the impact crusher the higher the wear. Fines inside an impact crusher is like sandblasting your consumables.
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 with a reduction ratio of 7:1 to 10:1; capacity 0.3 to 50 kg/s.
crusher components. • Small feed size increases wear at the bot-tom of the cavity and may cause poor uti-lization of wear parts. 2. Check the feed arrangement • In order to reach optimum capacity and maximize on the life of the wear parts, the crusher cavity should be full. • The feed must be distributed evenly across the crushing chamber. 3.
Download White Paper June 3, 2020. TAILORED SOLUTIONS. The Rio Tinto operated Hope Downs iron ore mine located in the Pilbara region of Western Australia, Australia operates HP800 crushers and was experiencing excessive wear and inconsistent life with their competitor supplied crusher liners, across all three cone …
Best suited for secondary crushing applications, cone crushers are designed to crush pre-sized materials, usually 100mm, 150mm or 200mm, depending on the size of the crusher. Cone crushers can form finished products down to 12mm or less. Like the jaw crusher, the cone crusher provides a relatively low cost crushing solution, but there are ...
Advantages of 6AF Hydraulic Impact Crusher for Sale: It is more convenient to replace the wearing parts with configuring the 500 kg maintenance boom.; The crushing cavity is larger by adopting curved design, which can meet the need of crushing larger materials.The counterattack liner adopts the saw tooth type, which can crush the material with higher …
As a basic rule, impact crushing is suitable for rocks with a low work index (<12) as well as low silica (<20%) and moisture levels (<5%). Rocks with these characteristics are soft and non-abrasive, and easily broken within the crushing chamber, keeping wear rates at a minimum, and producing high reduction ratios with a better …
Too small feed size for the cavity increases wearing at the bottom part of liners and may cause poor utilization rate of wear parts. Fines (0-4) should be screened away before the crusher as they may cause packing (AF secondary is not sensitive to fines). ... and crushability have a significant impact on the crusher capacity. 3. Check the ...
Wear rates were generally increasing with test temperature, especially FeCrC as it more than doubled from RT (0.0015 mm 3 /impact) to 0.0034 mm 3 /impact at 700 °C. The hardfacing FeCrNbBWC showed a 4-fold increase in wear rates at 700 °C compared to RT, nevertheless it was still observed to be the best material for this condition.
Feeding impact crushers. Size reduction in an impact crusher relies on energy being conveyed into the rock from the rotor, and it begins with your feed. The initial impact is responsible for more than 60 percent of the crushing action, with the remainder made up of impact against an adjustable breaker bar and a small amount of inter-particle ...
The crushers include machines with two and four bar rotors and the design and materials used for blow bars and wear liner plates provide maximum wear / metal utilisation factors. Impact arms of the crusher are …

A more advanced system using a laser scanner tool to profile the mantle and concave produces …
Depending upon the hardness of the crusher feed, the specific wear of the impact hammers is 1.5 to 3.0 grams per ton of crushed material. The wear rate of Cr-Va-steel is 3 grams and that of Cr-Si-Va-steel was estimated to 2 grams per ton of crushed material [47]. The rim speed of the hammers is in the range of 25 to 50 m/s.
Wear damage of the double roll crusher due to: (a) impact and (b) abrasion. The roll teeth experience greatest degree of damage with abrasion and impact damage levels being comparable. Fig. 25 shows various energy spectra for the double roll crusher.
manganese liner wear concentrated at the top of the liner. A feed that is too fine for the liner will cause high horsepower consump-tion, increased and irregular wear on bottom section of the crush-ing chamber, and high loading on the lower section of the crushing chamber, which can overload the crusher and cause bowl float.
• Reduced rock lining within the crusher, leading to possible crushing chamber damage. • An increase of larger gradation sized recirculating load, which can again in turn lead to crushing chamber and rotor wear part failure. Optimum operation of the crusher (lowest possible cost per ton), is always achieved when operating the crusher
The right wear profile improves crusher performance and extends wear life, leading to less downtime and fewer liner replacements, which in turn increases safety, reduces the cost per ton and the environmental impact. Our cone crusher wear parts are available for all crushers, but we also offer crusher wears for third party crusher brands.
