There are more than 13 million unique physical music releases in the Discogs Database. We categorize and connect releases in a few different ways at Discogs: by looking at the musicians who created them, the labels that produced them, the years that define them, and the formats you can find them recorded on. Genres and styles are another way to connect these releases, albeit in a more subjective way. Sometimes these nebulous similarities are geographic in nature; sometimes they are purely stylistic.
The genre and style definitions on Discogs are based on how releases are tagged by Contributors. Few releases have a categorical style, so they are often assigned based on subjectivity. Think about it how hard is it to accurately describe a piece of music? How many arguments over genres have you had with your friends?
Genres: The umbrella classification that houses different styles. Genres were decided by Discogs Contributors when the Database launched in 2000. They dont necessarily mirror genres defined by other high-profile sites (for example, Billboard). The genres on Discogs range from hip-hop to classical to stage and screen.
Styles: The more specific term that applies to different kinds of music, grouped together under genres. Discogs Contributors are consistently adding new styles to the Database, and you can too by submitting an official request. A style can be as broad as Ambient, as specific as New Jack Swing, or regional like Norteo.
Below, youll find an exhaustive list of all the styles in the Database broken up by their parent genre. We created this so Contributors can compare styles for new releases and as a fun way for you to unearth the different connections between releases. For an even cooler visual tool, check out our map of musical styles by region.
Hammer crusher has the characteristics of simple structure, high production efficiency, large crushing ratio and convenient maintenance. It is suitable for crushing various brittle materials, such as limestone, coke, coal, carbon, etc. The compressive strength of the material does not exceed 120Mpa, and the material humidity does not exceed 8%. Widely used in mining, electric power, metallurgy, aluminum carbon, cement, building materials, chemical and other industries.
Hammer crusher is a new type of crushing equipment by our company which was researched on domestic and foreign documents. The machine has the following characteristics such as simple structure, high productivity, large reduction ratio, maintenance easily. It is mainly suitable for medium and fine crushing brittle materials such as lime, coke, coal and carbon. It is suitable for materials with its compressive strength no more than 120MPa and moisture contenting less than 8%. It has been widely used in industries such as mine, power, metallurgy, aluminum carbon,cement, building material, chemical.
Many cement plants extract limestone by blasting, which often leads to oversized boulders containing a lot of clay and sand. The crusher therefore has to handle feed that contains larger blocks as well as some sticky materials. Our EV Hammer Impact Crusher is a proven, reliable and cost-effective impact crusher that help to overcome these crushing challenges.
In traditional hammer crushers with a top inlet, introducing large blocks in the feed can impede the action of the hammers and block the crusher. Our EV Hammer Impact Crusher, however, competently reduces quarry-size limestone boulders measuring up to 2.5 metres and weighing up to 5 tonnes to mill feed of 25 millimetres. This is a reduction ratio of 1:100 in a single operation. The EV Hammer Impact Crusher features a highly effective two-stage crushing process. Primary crushing takes place by impacting. Secondary crushing takes place by shearing and compression between the impact hammers and the breaker plate and between the hammers and the outlet grate. This ensures that even the smallest particles absorb energy and that no oversized particles leave the hammer impact crusher. The horizontal feed system can also tolerate coarse feed blocks because of its shock-absorbing inlet rollers.
The EV Hammer Impact Crushers throughput capacities range up to 2200 tonnes per hour (tph) with an outlet grate and 2500 tph without an outlet grate. Motor sizes are typically in the range of 500 - 2500 kW.
The hammer rows, which can vary depending on your crushing capacity needs, are arranged to provide complete coverage across the outlet grate. By arranging them in this way, the raw material can be crushed at multiple points increasing overall efficiency.
Adjustment of the spacing between the hammers, breaker plate and outlet grate can be optimised to compensate for hammer wear. Even when the hammers lose up to 30 percent of their original weight, the required product size curve is unaffected.
The adjustable outlet grate gives the EV Hammer Impact Crusher control of the maximum size of the product. The grate ensures a consistent flow to the conveyor and protects it against any sudden impact of material leaving the impact crusher at high speed. The grate also protects other nearby machinery from being damaged during operation.
The hold-up mechanism of the outlet grate generates a crushed product with a relatively high proportion of fines. In this way, more of the comminution work is moved from the less energy-efficient raw mill to the more energy-efficient hammer impact crusher.
The hammer rows are fitted in a staggered configuration to give complete coverage across the outlet grate. This provides several points for crushing of the raw materials, increasing the overall efficiency of the crusher.
The hammers are pivotally suspended from bolts and are symmetrically shaped. This reduces the full brunt from the contact between material and hammers, which protects the rotor and crusher housing. The hammers can easily be turned to reverse the leading and tracing edges for maximum service life.
Equipped with sturdy, replaceable grate bars supported by heavy cheeks, the adjustable outlet grate allows unique control of the mill feed size using hydraulic systems. This ensures a consistent flow to the conveyor. The outlet grate also serves as protection for the conveyor and other machinery such as reclaimers, sluices and mills, against operational upsets and mechanical damage.
A horizontal feed system incorporating one or two shock-absorbing inlet rollers helps to handle coarse feed blocks. The inlet rollers accurately control the feed to the hammer impact crusher and ensure a smooth and even flow of material. Whether one or two inlet rollers are used depends on the method of feeding the crusher.
Bolted-on, wear-resistant plates protect all exposed surfaces, including the adjustable breaker plates, from abrasive feed materials. The inlet rollers of the horizontal feed system consist of a cylinder and a concentric shaft driven by a separate motor. Rubber pads inserted between the shaft and the cylinder make the inlet rollers shock absorbent.
The hammer rotor assembly consists of a heavy-duty, forged shaft with a square cross section and is also fitted with rotor discs. The unique sandwich assembly of the discs is a robust construction, that helps prevent distortion and crack formation.
The top part of the EV Hammer Impact Crusher can be accessed by means of hydraulic cylinders. The supply package includes hydraulically-operated tools for fitting and dismantling of the heavy hammer bolts.
The hydraulic cylinders and tools are served by a mobile hydraulic power unit which can be stored in a separate room when not in use. A lifting yoke facilitates handling of the hammer rows when changing hammers. It also holds them in position when dismantling and fitting hammer bolts.

Hammer stone crusher is a kind of equipment that crushes materials in the form of impact. Crushing the size of 600-1800 mm material to 25m or less. Hammermill machine can not only be used in stone crusher plant, sand plant, but also can replace the cone crusher in the mineral processing.
JXSC hammer mill machine that hammerhead adopts a new technology cast which wear-resistant and impact-resistant. The airframe structure of the hammer mill is seal which solves the problems of dust pollution and dust leakage in the crushing workshop. And it is easy to maintain.
1. Hammerhead uses new cast technology which with wear-resistant and impact-resistant characteristic. 2. Can adjust the granularity size. 3. The seal structure that solves the problems of dust pollution and dust leakage in the crushing workshop. 4. The overall design of hammer crushing equipment has the advantages of beautiful appearance, compact structure, few wearing parts, convenient maintenance, etc.
Hammermill crusher mainly rely on impact energy to complete the crushing of materials. When the hammer mill rock crusher works, the motor drives the rotor to rotate at high speed, and the material enters the crusher cavity evenly. The hammerhead with high speed turns impacts and tears the material lead to the materials are crushed.
At the same time, the material from the high-speed rotating hammerhead to the baffle and screen strip in the frame under the gravity effect. The material larger than the size of the screen hole remains on the screen plate and continues to be hit and ground by the Hammer. Then finally through the sieve plate discharge machine until the crusher material size discharge.
The advantages of the hammer: The ratio of crushing is large, generally is 10-25, high up to 50. High production capacity. uniform products. Less over-powder phenomenon. Simple structure, light equipment quality. Simple operation and maintenance, etc. The series hammer crusher products are suitable for crushing all kinds of medium hardness and brittle materials, such as limestone, coal, salt, gypsum, alum, brick, tile, coal gangue and so on. The compressive strength of the crushed material shall not exceed 150 MPA.
The series of crushers are mainly used in cement, coal preparation, power generation, building materials, and compound fertilizer industries. It can crush the raw materials of different sizes into uniform particles for the next working procedure. Reliable mechanical structure, high production efficiency, good applicability.
But the hammer crusher also has some disadvantages, such as the hammer and grate screen wear quickly. When crushing hard materials, they wear out faster. When crushing sticky wet materials, it is easy to plug the screen seam of the grate. Therefore, it is easy to cause shut down, so the moisture content of the material should not exceed 10 %. When milling hard objects, the hammer and lining plate have big wear. And the consumptive metal material is much, often needs to replace the wear-and-tear piece.
