STONE CRUSHER LINE

The constitution of stone crushing production line

It consists of hopper, vibrating feeder, jaw crusher, impact crusher, vibrating screen, sand washer, belt conveyor and so on. (Depend on the actual condition)


The application of the equipments

(1)Vibrating feeder------continuously supply the raw materials

(2)Jaw crusher------the main type is primary crusher (CTNPE series), that is to say, the  materials transferred to the jaw crusher for the primary crushing. CTNPEX series for the secondary crushing: sometimes use the impact crusher or cone crusher instead of CTNPEX series jaw crusher.

(3) Impact crusher------mainly used for the secondary crushing. they can crush the stone to desirable size and good shapes.

(4)Vibrating screen------to screen the crushes material

(5)Belt conveyor------ to convey the materials. Transfer the material from one equipment to another.

1. materials

To select the suitable equipment, first, we need to know what is to be crushed, that is to say, the materials. The common materials to be crushed are granite, quartz, basalt, limestone, river gravel, iron ores and so on.

The materials¡¯ photos as follows:

What is the stone hardness? Different stones have different Mohs¡¯ scale of hardness. For instance, the Mohs¡¯ scale of hardness of the limestone is 3 Mohs; the quartz 7 Mohs; marble 3-4.4 Mohs; basalt 5-6 Mohs. Sometimes, the materials to be crushed may come directly from river, for example, river gravel, and the hardness of river gravel is very big. Of course, the hardness of river gravel depends on the actual geographic conditions. As usual, the bigger the hardness is, the less the output of the suitable will be from stone crushing production line. On the contrary, the more the output is. So the hardness of the stone is an important factor to be considered.

2. output

Usually, the output of the stone crushing production depends on the customers¡¯ requirement. It can manufacture from 20t/h to 800t/h of capacity. The output is decided by the processing capacity of stone crusher. The amount of output is an important factor to the input of the stone crushing production line. Generally, a 20t increase in the output per hour means $33000 increase in the capital input. The unit of output is t/h in the crushing industries. There are two ways to calculate the output.

(1)By weight. Knowing the processing capacity tons per hour will be better. But under the conditions of materials¡¯ volume and density, we can calculate the output. For example, the density of marble is 3.5-4T/M3 and the output is 100 m³/T, we can know the output is 350-400T/H.

(2) By the working hours. If the customer gives the working hours in a month or year, we still need to confirm the working days in a month or the working months in a year, then the particular working hours per day or month will be calculated out.

3. Feeding size

Feeding size is the decisive factor for the primary crushing.

In the crushing mill, there are varied sizes of stone after the crushing. There also maybe clay and waste products. If the content of clay and waste product is high, you need a vibrating screen to separate the stone materials and waste products firstly. It is true that the cost will rise. On the contrary, you needn¡¯t to do the screening. Then select the jam crusher type as per the stone volume.

4. Final product size

The customers should clearly know the size and amount of the final product. The more product kind you need, the more screen layers should have, the higher the cost will be.

The finer of the final product size means that more large stone will be transferred back to the jaw crusher for further crushing. For example, the processing capacity of the vibrating screen is 250t/h, perhaps 200t materials become the final desirable product, the remaining 50t will return back and will be crushed again.

If the final product size is sand with 10mm below, then the customer need to use sand making machine. If clean sand is needed, the sand washing machine shall be included in the production line.

The final product consists of various sizes product. The product requirements are size ranges with percentage. For example, : 0-10mm, 20%; 10-20mm, 30%, 20-30mm, 50%.

5. How to choose crusher manufacturer?

The following factors should be considered carefully: First, manufactures¡¯ strength, reputation and scale; second, manufactures¡¯ product quality, technical level and maturity; Third, visiting the work-site, for work-site speaks loudest. Finally, compare different manufacturers. Visit carefully, and do choose seriously.
