Detailed difference between crusher and ball mill
According to the modes of action of crushing force,crusher can be roughly divided into two categories:
(1) crusher;
(2) grinding machine.
So what is the difference between them?
Crusher and ball mill
crusher general handle big chunks of materials, product fineness is a little coarse, usually thicker than 8 mm. Generally speaking the materials grinding machine handled is fine, granularity of product is fine grained, can reach 0.074 mm, or even smaller.
About tectonic characteristics, crusher parts has a certain gap , they don’t touch each other. Crusher also can be divided into coarse crusher, middle crsher and fine crusher.
The structure characteristic of grinding machine is that crushing parts (or medium) touch each other, the media are steel balls, steel rods, gravel or ore blocks, etc. But some machinery both have crushed and grinding function concurrently, for example autogenous grinding machine. For ∮5.5×1.8m autogenous grinding machine, the ore size limit for processing can reach 350 to 400 mm, product fineness can reach – about 40% 200 meshes.
ore crusher is widely used in metallurgy, mining, building material, railway, highway, water conservancy and chemical industries etc. multitudinous departments. Now the common ore crushers are jaw crusher , cone crusher,gyratory crusher,impact crusher, hammer crusher, roll crusher, combined crusher etc.
Ball mill is the key equipment for repeat crush after the material being broken. Ball mill is widely used in silicate products, cement, refractory material, chemical fertilizer, new building materials, black and non-ferrous metal processing, glass-ceramics industry. It can grind all kinds of ores and other materials by wet or dry grinding. According to the material and discharging way, you can choose wet grate ball mill and dry ball mill.
All kinds of crusher have different specifications, different use range. At present, in beneficiation, coarse crushing adopts Jaw crusher or Gyratory cone crusher,medium crushing adopts standard cone crusher, fine crushing adopts short head type cone crusher. The coarse grinding uses the rod mill, fine grinding adopts ball mill.
To sum up, crusher and grinding machine all belong to a crushing equipment. Crusher and ball mill is an integral part of beneficiation equipments, crusher is mainly used to do the work at earlier stage, the ball mill is used to do the coarse grinding and fine grinding at later stage.
Debris screening industry

Sand production line application
The crusher designed sand making processing plant is specified for manufactured sand production, as well as fine or medium aggregate production with coarse material, rocks and minerals such as limestone, basalt, cobble, granite and slag. Sand making production line is widely applied in construction, highway, railway, civil construction and hydroelectric centrals.
crusher will provide you with customer made complete sand processing line according to your raw material hardness, input size, and required output.
Sand making production line process
crusher sand making line consists of vibrating feeder, jaw crusher , cone crusher, vertical shaft impact crusher (sand making machine), vibrating screen, sand washing machine, belt conveyor and central electric controlling system.
Raw materials (igneous rock for high compressive strength construction or sedimentary rock for hydroelectric centrals) are firstly transferred uniformly by vibrating feeder to jaw crusher for primary crushing. The crushed particulars less than 40 mm will be sent by belt conveyor to cone crusher for secondary crushing. The crushed materials of required size will then be transferred to sand making machine (vertical shaft impact machine) for the tertiary crushing. The resulted product is manufactured sand.
During the sand making process, vibrating screen plays the role of screening and separating particulars of different size. In the case of wet sand production process, you will need sand washing machine to effectively remove impurities of the final product. In the case of dry process, classifier and deduster will be attached to complete the same object.
Crushing Plant Maintenance Requirements
Crushing plants must be designed for ease of access and maintainability if they are to meet their production goals. Keeping maintenance requirements to a minimum helps achieve higher overall operating availability. Scheduled preventive maintenance at crushing plants involves a number of elements, including:
• Crusher wear parts • screen decks • feeder wear parts • conveyor skirting and adjustment • Oil and lubrication • Conveyor belt repair • Visual inspections • Electrical and instrumentation adjustments.
Provisions must be made for overhead cranes to remove and replace crusher wear parts. Supports must be provided for gyratory and conveyor main shafts and laydown space for the cone crusher bowls is essential. Some operators carry a complete spare screen and change out for major screen maintenance. Trolleys, jib cranes and pull points should be designed to facilitate equipment maintenance. Oil and lubrication systems should be centralized and designed for easy automatic changes, with provisions for well-ventilated centralized lubrication rooms where possible. (e.g., a line of fine cone crushers should have a central oil receiving area, with piping to and from each crusher lube package for quick and easy oil changes.)
Conveyor head chutes should be designed for easy access (not just through an inspection door, but through a man door in the chute). Conveyor belt change areas should be provided. Maintenance personnel should have easy visual and rapid access to screen decks for panel replacement. Designers should work with the screen manufacturers to ensure that covers provide good access for working on screens. Screening facilities must meet rigid dust emission requirements, but many off-the-shelf screen dust covers have not kept pace with these requirements. It may be necessary to custom-design covers that minimize emissions and provide easy access to the screen.
Climatic Conditions
Building for cold-weather operations is very challenging, as is designing a plant in a desert environment. This is particularly true when year-round operation is required. Seasonal variations can change ore moisture content, so the crushing plant must be adaptable to changes in the material flow characteristics. Higher moisture requires greater angles of withdrawal, and stoneboxes must be designed to avoid plugging. The crushing plant equipment itself must be adjustable to climatic changes; for example, screen decks must be designed to maintain production, possibly by using wire mesh during the wet season and plastic during the dry. (Vary screen deck types dependent on seasons and material characteristics to achieve maximum passing through deck openings.
Climate also dictates the type of plant enclosures required as shown in Figures 1 and 2. Many crushers in milder weather climates or desert areas are installed with an open face and have no enclosures at all.
Crushing of hard Materials
Processes used for crushing hard materials
These processes are used to reduce a material from its original size to a smaller, defined output size.
The main physical size reduction processes are: shattering (breaking), squeezing, grinding.
Shattering (breaking) is used, as a rule, to reduce materials with grain sizes of > 50 mm in size. In squeezing and grinding processes, materials already reduced to grains sizes of 5 50 mm are reduced/ground to extremely small grains. The boundaries between squeezing and grinding are fluid.
Machines used for crushing hard materials
Machines used for crushing hard materials can take materials with edge lengths of up to 2500 mm and reduce them to sizes of a few hundredths of a millimeter in a series of processes. In these machines – crushers, mills and presses – moderately to extremely hard stones, other minerals, coal and sands are processed. Depending on the material and on the desired end product, the following machines may be used:
- jaw crushers
- Cone crushers
- Hammer crushers
- Roller grinding mills
- Roller presses (cylinder crushers) – Tube mills
Machines used for crushing hard materials must be characterized by a high efficiency and operational reliability, and they must be easy to maintain. As a leading rolling bearing manufacturer, FAG are making their contribution to meeting these requirements.

Crusher Machine in Europe
Crusher Machine in Europe
In Europe,the greatest cost to mining crushers in real terms is not the purchase price of a mining machine, but its operating costs over time, reports crushing equipment supplier Liebherr in Europe mining crusher industry.
With the dollar:rand exchange rate and diesel being imported, fuel efficiency is a critical cost factor for Europe crusher. Another cost factor in crushing equipment is the comparative productivity of a crushing machine and its maintenance costs in Europe. Trans Hex group mining equipment engineer Keith McCulloch says that the company has found the crushing equipment supplier’s to be cost-effective across a range of applications, and singles out the wheel-loaders as units which come in at substantially lower fuel costs, proved in field trials. He also praises the hydrostatic drive system as efficient and cost saving in Europe.
The diamond producer’s fleet includes three of the crusher supplier’s R 994 tracked hydraulic crushers ranging from one to four years old, used for overburden removal and prospecting; five R 984 hydraulic excavators and two R 974 excavators ranging from three to six years old, which are used for ore recovery and overburden removal compared with other crusher equipment in Europe. One of the crushers is working at Reuning Mine, another at Bloeddrif, with two more crushers, one fitted with a ripper at Saxendrift. A total of six crushers, including an older L 551 and five L 564s are used for loading run-of-mine ore into hoppers and as general plant tools at Saxendrift and Baken Mines. Among the company’s branded cranes are a four-year-old LT 1025 mobile crusher and an LTM 1060 mobile crusher purchased last year, both of which were used to help erect the new dense-media separation plant, currently being commissioned at Baken, as well as for general mining crusher and equipment maintenance applications.
The diamond producer of Europe also led the industry move in the last few years in breaking with the long-standing tradition of using 65-ton crushers coupled with blasting, in favour of the the supplier’s mining crusher. The diamond producer began using the crushers at Baken, as part of the group’s expansion strategy to maximise productivity by matching the crusher and bucket capacities to the application and size of the loading trucks used. The larger mining crushers were extremely successful in improving productivity, and their breakout forces allowed the mine to break out up to 90% of the layered material characteristic of the Orange river area using the crushing machine exclusively, so also mining expensive blasting. Many other mines subsequently followed the diamond producer’s lead, and even the smaller diamond digging operations started using 100 t class crushing machines.
According to the crushing equipment supplier in Europe, the demand for inceasingly larger crushing machines is an international trend in mining of Europe, as the industry chases production to keep financially viable in a highly competitive environment. While the move from 65 to 100 t crushing machines was relatively recent, the even more powerful crushers in the 300 t to 600 t category, are now proving popular with mining and contract mining clients of Europe, the firm claims.
Crushed Stone Processing
Crushed Stone Processing
Major rock types processed by the crushed stone industry include limestone, granite, dolomite, traprock, sandstone, quartz, and quartzite. Minor types include calcareous marl, marble, shell, and slate. Major mineral types processed by the pulverized minerals industry, a subset of the crushed stone processing industry, include calcium carbonate, talc, and barite. Industry cla ssifications vary considerably and, in many cases, do not reflect actual geological definitions.
Rock and crushed stone products generally are loosened by drilling and blasting and then are loaded by power shovel or front-end loader into large haul trucks that transport the material to the processing operations. Techniques used for extraction vary with the nature and location of the deposit. Processing operations may include crushing, screening, size classification, material handling and storage operations. All of these processes can be significant sources of PM and PM-10 emissions if uncontrolled.
Quarried stone normally is delivered to the processing plant by truck and is dumped into a bin. A feeder is used as illustrated in Figure 11.19.2-1. The feeder or screens separate large boulders from finer rocks that do not require primary crushing, thus reducing the load to the primary crusher. Jaw, impactor, or gyratory crushers are usually used for initial reduction. The crusher product, normally 7.5 to 30 centimeters (3 to 12 inches) in diameter, and the grizzly throughs (undersize material) are discharged onto a belt conveyor and usually are conveyed to a surge pile for temporary storage or are sold as coarse aggregates.
The stone from the surge pile is conveyed to a vibrating inclined screen called the scalping screen. This unit separates oversized rock from the smaller stone. The undersized material from the scalping screen is considered to be a product stream and is transported to a storage pile and sold as base material. The stone that is too large to pass through the top deck of the scalping screen is processed in the secondary crusher. Cone crushers are commonly used for secondary crushing (although impact crushers are sometimes used), whic h typically reduces material to about 2.5 to 10 centimeters (1 to 4 inches). The material (throughs) from the second level of the screen bypasses the secondary crusher because it is sufficiently small for the last crushing step. The output from the secondary crusher and the throughs from the secondary screen are transported by conveyor to the tertiary circuit, which includes a sizing screen and a tertiary crusher.
Tertiary crushing is usually performed using cone crushers or other types of impactor crushers. Oversize material from the top deck of the sizing screen is fed to the tertiary crusher. The tertiary crusher output, which is typically about 0.50 to 2.5 centimeters (3/16th to 1 inch), is returned to the sizing screen. Various product streams with different size gradations are separated in the screening operation. The products are conveyed or trucked directly to finished product bins, to open area stock piles, or to other processing systems such as washing, air separators, and screens and classifiers (for the production of manufactured sand).
Crushed stone plant
Some stone crushing plants produce manufactured sand. This is a small-sized rock product with a maximum size of 0.50 centimeters (3/16 th inch). Crushed stone from the tertiary sizing screen is sized in a vibrating inclined screen (fines screen) with relatively small mesh sizes.
Oversized material is processed in a cone crusher or a hammermill (fines crusher) adjusted to produce small diameter material. The output is returned to the fines screen for resizing. In certain cases, stone washing is required to meet particulate end product specifications or demands.
