Vertical Shaft Impact Crusher

1, sand making machine What is the equipment? What is sand making machine?

sand making machine system is used for artificial sand equipment, according to materials in and finished request, it could be counter broken, can be broken cone, can also vertical shaft impact crusher, according to the extent and scope of industries, the vertical shaft impact crusher Machine is the application of the most extensive equipment, the industry usually known as vertical shaft impact crusher sand making machine is, in fact sand making machine not limited to the vertical shaft impact crusher. Vertical shaft vertical shaft impact crusher from the feed, the feed, whirl crushing chamber, impeller experience, spindle assembly, chassis, transmission and electrical seven components. It is widely applicable to different types of rock, abrasives, refractories, cement clinker, quartz stone, iron ore, aggregate concrete, and other hard, brittle materials in the debris, a chronology (of sand). Construction sand, gravel roads used for the appropriate distinctions.

2, how to choose sand making machine manufacturers?

First of all manufacturers depend on the strength, reputation, size; Secondly manufacturers depend on the quality of products, technical level, level of maturity; Inspected again to the manufacturers, production site, users scene is the most convincing. Shop around final must be carefully inspected and selected carefully.

3, What is the sand making machine principle? The vertical shaft impact crusher (sand making machine) as an example.

Materials from entering into the crusher hopper, feeder by the materials will be divided into two parts, part of the feeder from the middle to high-rotating impeller, the impeller being rapidly accelerated its acceleration up to several hundred times the acceleration due to gravity, and then to 60-70 m / s speed impeller three from the uniform flow of projectile out, first of all, with the feeder from around since fallen to a part of materials vertical shaft impact crusher, and then a shock to the vortex cavity-lining materials, , the lining material rebound oblique impact on the cavity to whirl at the top has changed the direction of its movement, deflected downward movement of the rotation, fired from the materials formed by the continuous material screen. Such a material whirl broken twice by the cavity and repeatedly hit probability, friction and grinding fragmentation. Be broken by the lower nesting materials from the mouth. Screening and recycling of a closed-circuit system, three general circulation materials can be broken into the following 20 orders. Under broken in the whole process of mutual self vertical shaft impact crusher materials, direct contact with the metal components, but with a lining material impact, friction smash, which reduce the pollution angle, mechanical wear extended time. Whirl ingenious internal cavity flow from circulation, eliminate dust pollution.

4, what problems the vertical shaft impact crusher (sand making machine) in the process of running will arise?

Working mainly spare parts and consumable parts in high-speed condition more serious problem of wear and tear, especially the impeller wear vertical shaft impact crusher normal work.

5, how to solve vertical shaft impact crusher (sand making machine) the problem? Also vertical shaft impact crusher (sand making machine) is the key issue.

How to solve the crushing machine parts and components and consumable parts in such high-speed conditions of wear and tear, so that equipment will operate normally? This particular that of a high-speed vertical shaft vertical shaft impact crusher industrialized use of the key problems. Therefore, although this crusher is an efficient and product size and grain shape superior characteristics it has been to 20 in the 1980s did not achieve a breakthrough.

Until the mid-1990s the world's leading firms to solve the wear this critical issue.

First of all, and designers to use the "stone at Stone 'new ideas to the actual production in order to achieve the" stone at Stone "design intent." Stone at stone', the stone is the impact of broken stone, stone formation from lining working components so that the wear and tear of the machine itself. Since stone lining to protect the vulnerable parts without itself is broken materials. Stone at work constantly undermining a form of a broken clock security updates make it to be effective since lining.

Second, designers material aspects of machine components to achieve a breakthrough, high wear-resistant materials used since lining the floor. In the structural design of effective measures have been taken to dismantling most aspects.

Third, designers to increase the line speed and reduce crusher feed particle size, so that for the third or fourth broken. Crusher reasonable work for the creation of a good working conditions. sand making machine work features:

(1) simple structure, and low cost. (2) Efficiency, broken high efficiency. (3) a chronology, coarse grinding function. (4) through non-broken materials, and a strong ability to affect small water materials, moisture may reach 8 percent (5) can be broken in the hardware, special hardware materials (such as corundum, sintered aluminum V soil, etc.). (6) a cube products, iron contamination small. (7) impeller and whirl since broken cavity lining materials significantly reduce maintenance costs and wear and tear of the workload. (8) operation and maintenance, and ease of installation, (9) The noise of less than 75 dB (dB level), (10) light weight, installation methods and diverse, mobile installation characteristics.
