Cone crusher from DSMAC help you crush river pebble

With more and more sand is needed badly, river pebble and granite have been the main raw material for sand making production line. In the world, there is a large amount of river pebble, which can be used to make a lot of sand to meet the building material needs. So, the river pebble crushing equipment has been more and more popular in market.
Now, the river pebble crushing equipment consists of jaw crusher, impact crusher, cone crusher and vertical impact crusher and so on. While the cone crusher is the best choice for a small 30-300t/h river pebble production line. But why we select the cone crusher to crush river pebble, the most professional experts from DSMAC give us these three reasons:
1. Reduce the wear of crusher spares and expand the crusher service life. As we all know, Sio2 is the main chemical composition of river pebble. So it is very hard. If we choose the hammer crusher to crush, the crusher hammers will be seriously worn, even leading to a low capacity. While the cone crusher adopts the theory of “layer pressing”, so it is more suitable for crushing hard river pebble, which can improve the crushing ratio and capacity, greatly reduce the spares’ wear and expand the crusher service life.


2. The final products have good shape. Apart from crushing river pebble, the cone crusher also has the ability of fine crushing and coarse milling for river pebble. In addition, the final products have good shape, the cubic products can reach over 90%, and the final products are even and have good gradation.
3. Realize the exchange of coarse crushing, middle crushing and fine crushing through the exchange of cavity types. The cone crusher has large crushing ratio and large capacity. The cone crusher from DSMAC adopts the modularity design, which can realize the exchange of coarse crushing, middle crushing and fine crushing through the exchange of crushing cavity types. So the cone crusher has adjustable capacity and wide applications.

So, in order to meet the needs of different clients, DSMAC Group offers our clients a series of cone crushers, such as PYS cone crusher, PYT high-energy cone crusher and GNY hydraulic high-energy cone crusher and so on.

Some basic principles of designing a crushing plant

Designing a crushing plant to obtain the lowest cost per ton produced, and meet your market needs, requires balancing the entire process.

•Starting with the best method to extract the raw material and deliver it to the crushing plant

•Designing the crushing plant to be able to process that raw feed and then produce the final marketable products

•Choosing the equipment so all components work together efficiently

Designing a crushing plant is similar to designing a manufacturing production line. All components must work together to create a smooth flow, consistent production, and as uniform final products as possible. The raw material can change during the life of the operation, weather can influence the operation, and normal wear can affect the production and quality of the output of the plant. The plant operator must be constantly adapting the operation to reflect these changes. In the end, crushing is an art rather than an exact science.

There are some basic principles that if followed will help you obtain the greatest production with the least capital investment and lowest operating costs.

• The raw feed needs to be as uniform in gradation, type, and feed rate as possible.

• Remove all rock that is already smaller than your discharge setting prior to feeding each crusher.

• Using grizzlies and screens to reduce the amount of material that needs to be crushed will save you capital costs and operating costs.

Primary crushing is normally done by horizontal shaft impactors, gyratory crushers, or jaw crushers, and sometimes cone crushers.

Secondary crushing can be accomplished by using a jaw crusher, horizontal shaft impactor, or a cone crusher.

Tertiary crushing is normally done using a fine, shorthead, or PYG cone crusher, and vertical shaft impactor.

Roll crushers are used both for secondary crushing or when fewer fines are wanted, such as producing “chips”.

For more information on the various types of rock crushers, their method of crushing, and the average reduction ratios they produce, please go to crushers types.

For more information on various crushers go to cone illustrations. For pictures of some aggregate plants.

All crushing is based upon starting with a raw resource and transforming it into final products or a from which you can extract value from. It is important to konw what you are starting with,and what you want to end with. It is that information that is used to determine what equipment you will need.

Basic information needed includes:

1. What are the physical characteristics of the rock? Type of rock? Hardness of rock? Chemical composition of the rock? Weight per unit of measure (such as pounds per cubic foot or kilograms per cubic meter)? Is the rock abrasive? Average moisture content?

2. Gradation of the rock? What are the average percentages of each size range?

3. Source of the rock? Is it from a sand and gravel deposit, or a shot rock quarry?

4. How many tons per hour can you supply the plant?

5. What is your market demand? What is the demand for certain size ranges?

6. How many different products will you need to produce? What is the size range of each product?

7. Do you want to have your operation stationary or portable? Portable equipment costs more to purchase, to ship, and to maintain.

8. Do you want equipment that is simple in design, easy to trouble-shoot and repair, and built to last.

9. Do you want equipment that uses high technology such as electronic sensors, computers, control consoles, and designed for high production but short useful life.

How to choose a more suitable limestone crushing equipment?

Limestone brief information
Limestone is also called calcite or Caco3, whose MOH is three. Limestone is a kind of rock which contains single calcite ore composition, in which the calcite accounts for 95%, and some few minerals are also contained, such as dolomite, siderite, quartz, feldspar, mica and some clay ore compositions who can embody the ore color. And the pure limestone is white.

Limestone material size, hardness, discharge size, capacity can affect to select of the machine:

For one part, we can select the suitable limestone crushing equipment according to the raw material size. If the raw material size is over 1 m, we should choose the jaw crusher, impact crusher or hammer crusher as the primary crushing equipment, and the impact crusher, cone crusher or XPCF high-efficiency fine crusher as the secondary crushing equipment.

If the raw material size is less than 400 mm, we can choose the high-efficiency cone crusher or DPX fine crusher, which both can crush the material into the standard particles size meeting the clients’ needs.

For another part, the limestone hardness is very small, so all the common crushers can meet its hardness requirement.

 

For the third part, if we want to have the limestone crushed into a very small size, such as 0-5 mm, we should choose the limestone production line. In this line, we can choose the primary crushing equipment, and select the deep cavity jaw crusher, high-efficiency cone crusher, or high-efficiency fine crusher as the last crushing equipment according to our output material size requirements.

What’s more, if we want to have large limestone capacity, we can choose the impact crusher as the secondary crushing equipment.

Therefore, more crushing and less grinding efficiency is more significant, crushing and grinding power consumption is reduced greatly. Perfect combination of high crushing efficiency and highly efficient chamber makes larger capacity than other crushers. More materials are crushed by different layers, so size of final product is evenly cubic.

Features

1. Materials are crushed into much smaller size, so more crushing and less grinding efficiency is realized. The crushing capacity in the following process is increased, and the system power consumption is reduced.

2. Larger capacity and smaller size of final product reduce cyclic load, so chute of vibrating screen and belt conveyor are worn slightly, and power consumption of belt conveyor is reduced too.

3. Spare parts can be easily changed, so downtime is shortened.

4. Hydraulic adjustment and method for cleaning chamber make operation and maintenance much more convenient and automatic.

5. This series of Single Cylinder Hydraulic Cone Crusher has much less trouble, and operating ratio is increased more than 85%, so the whole cost is reduced greatly.

Working principle:

Crushing process is completed between the fixed cone and eccentric rotating moving cone.  Horizontal axis of crusher is driven by motor through the V-belt, and drives eccentric cover by gear.  Eccentric cover makes main shaft rotate to cause eccentricity.  Materials enter crushing chamber through upper inlet of crusher, and are discharged out through lower outlet.

Advantages

1. Human design and hydraulic adjustment of discharge outlet save time and work. Adjustment can be controlled precisely.

2. Single hydraulic system adjusts main shaft and body, the body can rise and decline integrally to adjust discharge size, so side cylinder and upper frame with slope can be avoided.

3. Working pressure system can be adjusted hydraulically, pressure adjusting system can discharge super hard materials to protect the machine.

4. Spare parts can be changed easily. Fixed cone and cone body combine stably after precise design, and filler is not necessary to be filled again, so time to change spare parts can be saved. Fixed cone is installed stably, so stuffing is not necessary to be filled.

5. Hydraulic pressure of the whole machine is so low that it gives lower pressure to the main frame, and hydraulic system lasts longer.

6. The machine is designed with small size, so installation and transportation are very convenient.

The equipment advantages of coal crushing plant and grinding process from dsmac company

Coal

Coal is a readily combustible black or brownish-black sedimentary rock normally occurring in rock strata in layers or veins called coal beds. The harder forms, such as anthracite coal, can be regarded as metamorphic rock because of later exposure to elevated temperature and pressure. Coal is composed primarily of carbon along with variable quantities of other elements, chiefly sulphur, hydrogen, oxygen and nitrogen.

Coal crushing plant

In order to use coal more rationally, efficiently and effectively, the coal need to be processed and crushed into different sizes, 0 ~ 25 mm particle size for coal gas stove, 25 ~ 8 mm for steam locomotive, 25 ~ 6 mm for the industrial furnace, and coal power plant requires grain coal of 0 ~ 25mm. So coal process in coal preparation plant includes coal crushing and coal milling.

Coal crushing and grinding process

So in order to get the needed particles, Coal crushing plant consists of many types of crushers and grinding mills. Coal crushers include primary jaw crusher, secondary Impact crusher and cone crusher etc. Coal mill includes ball mill, Vertical mill etc.

If the coal block is bigger than the mill’s max input size, it must be crushed before grinding. The crushing plant common includes vibrating feeder as feeding material to jaw crusher, which is as primary jaw crusher. If need secondary crusher, Cone crusher or Impact crusher can be used. After primary crushing, the coal can be fed to Ball mill to fine grinding. To increase Ball mill effectively, the vertical coal mill or coarse powder mill can be set before Ball mill as pre-grinding.

The equipment advantages from DSMAC in this process

Jaw crusher: coal jaw crusher is the most common crushing machine. Usually it is used as primary crushing machine with high crushing ratio, high capacity, little dust, low noise and reliable performance etc. Using two jaw plates extrude the raw coals to small pieces.

Impact crusher: coal impact crusher is also the common crushing machine for coal. It is used after jaw crusher for secondary crushing. Impact plate with high chrome is wearable. The coal after crushing is cubic in shape. Also, it features quick and easy installation, very simple design with high mechanical reliability, simple to use and fixed or mobile applications.

Cone crusher: coal cone crusher is fine crushing machine in this process. It has these types: spring cone crusher, hydraulic cone crusher etc. Spring cone crusher is the early cone crusher, while Hydraulic cone crusher is adjusted by hydraulic device and lubricated by the dilute oil. And with locking sleeve assembly, it can overcome the trouble of oil and water being mixed together.

These coal crushing machines are not used alone, they compose a complete crushing plant with belt conveyor and vibrating screen. In Electric Power plant, coal gasification and clean coal process, crushing process is the first step and essential step. Natural coal is fed evenly into jaw crusher through belt conveyor, and after being crushed, it enters into impact crusher or cone crusher for fine crushing. Final it is screened out by screening machine.
