Hammer Crusher Application Field Mining, metallurgy, building material, cement, quarrying, gravel & sand making, aggregate processing, recycling, and chemical industry, etc. Suitable Material Limestone, slag, pebble, rock gold ore, salt, concrete, coal, coke and other materials in the primary/secondary crushing and fine crushing operations.

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.

Processing Materials: silica, iron ore, granite, gangue, river pebbles, calcite, limestone, bluestone, coal, gypsum, glass, cement, bricks, tiles, and some mental ores.

Hammer crusher is also called hammer mill crusher or industrial hammer mill, which can be used in the dry or wet crushing processes. It can crush materials into the required size in one time to save lots of energy and investment costs.

According to different features of different materials, HXJQ has improved the hammer crusher in its structure, application and function, and developed coal hammer crusher, glass hammer crusher, ceramic hammer crusher, cement hammer crusher, gypsum hammer crusher, limestone hammer crusher, quartz hammer crusher, etc.

1. Reversible type hammer crusher is often used for fine crushing process, and the finished products are uniform and fine. Reversible type hammer crusher has a large crushing ratio and can work stably.

2. Irreversible type hammer crusher is usually used for medium crushing process. Because its rotors can't rotate back and forth, it is also called as the impact hammer crusher. Irreversible type hammer crusher combines the advantages of hammer crusher and impact crusher and performs well in the crushing process. It is a technical and compact crushing machine with the features of low energy consumption, high capacity and low price.

Hammer crusher is used to crush materials with medium hardness and low corrosivity. The compressive strength of materials processed should be no more than 200Mpa, and water content should be lower than 15%.

Hammer crushing equipment is suitable for processing coal, gypsum, brick, tile, limestone, quartz, iron ore, granite, basalt, gangue, river pebble, calcite, wollastonite, bluestone, glass, cement, and other metal ores. Also, it is used to crush wood, paper, construction waste and recycled asbestos fiber, etc.

Besides, the hammer crushing machine can be not only applied in the crushing process and sand making process, but also can be adopted as the secondary crushing equipment to replace cone crusher and impact crusher, and used in the beneficiation processing line.

Hammer is made of high-quality manganese steels and treated by strict heat processing and then it becomes single austenite. After the process, the service life has been prolonged 4 times than traditional hammer crushing machines and working efficiency has been improved more than 30%.

The crushing process of hammer crushing machine is that the power drives the hammer to crush materials, and the crushed materials are impacted on the counterattack plate, and then the materials rebounded by the counterattack plate hit the materials impacted by the hammerhead.

Hammer crusher mainly relies on the impact force to complete the crushing. When the hammer crusher works, the motor drives the rotor in high-speed rotation. The materials are sent into the crusher chamber evenly and after a high-speed impact of hammer, the material is crushed into a smaller size.

The material larger than the sieve mesh is remained in the screening plate for further impacting and grinding. The material smaller than the sieve mesh is discharged from the hammer crushing machine to the material piles.

HXJQ as one of the professional hammer crusher manufacturers in China, mainly produces jaw crusher, cone crusher, hammer crusher, impact crusher, sand making machine, vibrating screen, feeding machine, sand washing machine and supporting equipment such as dust collector and conveyors, etc.

HXJQ undertakes various construction projects of large-capacity sand and aggregate production lines and serves from the equipment design, manufacturing, project survey, production line design, construction, equipment installation and debugging to after-sales service.

crusher type and product shape - crushing, screening & conveying - metallurgist & mineral processing engineer

crusher type and product shape - crushing, screening & conveying - metallurgist & mineral processing engineer

Try Chapter VI "Attributes of Comminution" in A M Gaudin "Principles of Mineral Dressing" First Edition (1939) page 124. "The shape of crushed or ground particles varies but little with size and the finest particles that can be examined under the microscope are as angular as any".Note though, that the separation device after the crusher or grinder may affect the shape of the product (screen or cyclone, for example).

One obvious exception I must mention is that of malleable materials such as gold (in an old-fashioned stamp mill, for example). In this case the shape of the particle will be distorted by the 'crushing' process.But, in general, (and I think that this is the point of the question), we see little change in particle shape parameters by comminution processes (such as micronization in the pharmaceutical industry). Materials split along cleavage planes and the basic crystal shape is preserved in size reduction. Gaudin knew this well in 1939.

What I am trying to figure out is which crusher would give a definite type of particle (cubical, flaky, etc), because this might help me to take a decision about which crusher to pick in a determined process (metallurgical processes preferably).

Unfortunately it doesn't work like that; the only way to get (approximately) cubic particles out is to start with a material with cubic structure - for example NaCl or perhaps iron pyrites. Mica or talc would produce flaky particles on comminution.

All you could do is put the processed material through, say, a screen and this would select somewhat on the basis shape (also a cyclone where there's also a separation based on size, shape, and density).The shape of the starting material governs the shape of the crushed material- back to Gaudin again.

To some extent, one can effect on the particle shape with crushing. I take an example. Flaky chippings (do I use the right word?) for roofing felt is produced from shale type of rock material. If you crush this type of rock with a cone crusher, the shape of the particles is more cubical compared if you do the crushing with a hammer (impact) crusher. Impact crusher obviously produces better chips for the said purpose.For more amorphic or nonoriented rocks type of crushing obviously is of lesser importance.

HPGR crushers are said to produce fragmentation along grain borders.To produce cubical particles is very difficult unless impossible. (Of course, you can find one almost cubical piece from 10 000 pieces of crushed rock.)

Speak to Magnus Evertsson from Chalmers University. They have conducted lab-scale as well as industrial tests to improve the yield of crusher product shape. They have developed control methods to produce particular shaped product based on the CSS, throw and compression ratio. There are opportunities in the down-stream process if you can bias the crushing to produce particular product shape. Read "The Effect of Blends of Rock Shapes in AG / SAG Mills and Comminution Circuits" - SAG 2011

Yes, I agree there can be some selectivity for shape especially if a shape specific separation technique is utilized after the comminution stage. However, I would think that such selectivity would be small - although I'd love to be proved incorrect! The example of shale is similar to that of mica and talc and shows the validity of Gaudin's comment in 1939 - again we're starting with a material that cleaves along a preferred axis or grain boundary - exactly as states. The other roofing example is roof tiles (shingles in the US) made of slate - these are made by a size reduction process in the broadest sense.

A high speed high throw crusher, like the Weir Enduron cone is used in the aggregate industry for cubic shape. If you requirea finer product size than the Enduron VSI could be what youre looking for.How many tons per hour do you need to process?

A VSI crusher such as a Barmac will provide an improved cubical shape to slabby or flaky feed material. The rolling action within this type of machine will act on the total feed gradation curve. The downside is it will also produce an increase in proportion of attrited fines.
