Heavy duty hammer crusher

Description

Heavy-duty hammer crusher commonly known as spindle breakage; It is a new heavy-duty hammer crusher developed on the basis of the user feedback information and the development of the crushing industry, which is suitable for the material size does not exceed 160Cmm and the crushing resistance is less than 150MPA. Calcium content ≥40% brittle materials, such as limestone, bluestone and other materials, suitable for mining, cement, building materials, chemical and other industries. It has the advantages of one break molding (less than 600 tons per hour), large feed size, high crushing ratio, large yield, round grain shape and so on. Compared with the traditional hammer breaking, the operation is more simple, the operation is more safe and reliable, and the maintenance is more convenient. In the case of suitable mineral physical properties, this series of crusher can directly replace the jaw break! Counter break (one break against two breaks) use, larger output, more perfect grain shape, crushing + finishing machine to achieve. Therefore, this series of crushers will become the mainstream of the market instead of the traditional hammer crusher.

Performance Advantages

• 1. Large feeding size and high output The maximum feed size can reach 160mm, the crushing ratio is high, and the output can reach 300 tons. The crushing shin design conforms to the dynamic principle, the unique non-grating structure design, increases the material passing amount, can break wet material, and solves the problem that the traditional hammer is easy to jam and the output is low.
• 2, a broken molding, low investment, fast return When the production is below 600 tons, it can be broken (instead of jaw + counterattack) : the production of 150C tons can be 2 sets, the multi-stage crushing can be changed to -stage crushing, and the low-cost transport palace of one break against two breaks is completely realized, and the same output cabinet is reduced by about 35% than the jaw break + counterattack.
• 3, good grain shape, flaky rate of powder yield is low The crushing chamber design is more in line with the dynamic principle of the platform. After the material enters the tablet breaking machine, it is broken in 3 stages, and the grain shape becomes a cube and the grading is reasonable, which meets the national building materials standard. The unique flow trough design of the lining board can automatically discharge qualified materials with a diameter smaller than the gap, reduce the repeated crushing of materials in the crusher, and greatly reduce the powder yield.
• 4, super wear-resistant rotor The unique patented rotor disc wear-resistant retainer technology overcomes the disadvantages of serious wear of the traditional rotor disc and the trouble of artificially surfacing the wear-resistant layer. The wear-resistant retainer is fixed to the rotor disc through the pin circlip, which has strong wear resistance and easy replacement. The cylinder is designed with eight hammer shaft holes and four spare ones. The hammer shaft holes are embedded with alloy steel shaft sleeve, which greatly extends the rotor
• 5, the structure is more reasonable Crusher back adopts through reinforcement structure, double nut fixed, rotor hammer can be rotated 360 degrees, single hammer weight, rotor disc diameter, reasonable speed, can resist the strong impact of large materials, shell inner panel arranged tightly by 10.9 high strength square fixed to ensure that the shell is firm and never deformed, the size of the discharge particle is adjustable. After the optimized design of the lower shell, the traditional way of controlling the discharge particle size of the hammer is changed, the wear of the hammer head in the crushing chamber is reduced, and the life of the hammer head is increased by 3-5 times, which is more energy saving and more efficient.
• 6, more durable wear-resistant hammer head Our company focuses on the research and development and production of crusher hammer head, so far has more than 20 years of wear-resistant bell head casting, production experience, with an independent modern casting room and casting parts spectrum analyzer, can produce a single weight of 10 tons of wear-resistant castings. All wear-resistant parts on the crushing equipment are produced by their own foundry, strict control of the quality of parts, the production of Gaoming alloy double-liquid composite hammer, has won the "China's best hammer prize", by the industry's police as "the most wear-resistant crusher hammer".
• 7, independent shaft plate structure Independent shaft plate structure: each hammer shaft baffle can be controlled separately, and the replacement of the bell head is more convenient and fast. The structure is safe, reliable and replaceable.
• 8, hydraulic counterattack frame When the hammer head or movable liner reaches a certain degree of wear, the spring box rear backing plate can be increased or reduced through the hydraulic adjustment device: to achieve free adjustment of the movable liner to the hammer head, the operation is simple, convenient and quick.

Working Principle

The hammer crusher uses impact to break materials. The main working part is a rotor with a hammer head, which is composed of a spindle, a disc, a pin and a hammer head. The motor drives the rotor to rotate at high speed in the crushing chamber, and the material enters the machine from the upper feeding port, and is crushed by the blow, impact and grinding of the high-speed moving hammer head. In the lower part of the rotor, a screen plate is provided, the particle grade of the crushed material less than the size of the screen is discharged through the screen plate, the coarse particle grade greater than the size of the screen is blocked on the screen plate, continues to be hit and ground by the hammer head, and is discharged through the screen plate.

Question&Answer

Q：Is the heavy hammer crusher easy to use? Can hard stones be broken?

A：Hammer crusher is suitable for processing medium and soft ore, such as limestone, coal gangue, dolomite, shale, etc., can also deal with high hardness materials, but the hammer head wear quickly, better frequency is higher.

Q：What are the components of the hammer crusher?

A：The main working part of the hammer crusher is the rotor, which is composed of a spindle, a disc, a pin, a hammer and other parts.
