European Version Jaw Crusher and Ordinary Jaw Crusher Difference?

What is the difference of european version jaw crusher and ordinary jaw crusher? How to choose a suitable crushing machines according to different requirement an save cost? European version jaw crusher feed port is of V-shaped, the actual material feed size is slightly larger than GM jaw crusher machines, the adjustment method is also different. Generally use Universal broken jaw adjust discharge range adopt drawing and push rod. Jaw crusher PE900, PE 1200 and other have hydraulic adjustment set; European version jaw breaking machines use of wedges and hydraulic adjustment. European version jaw crusher’s productions are between 10-600 tons per hour.

Final Crushing Particle Percentage Range is?

Compound fixed stone production line, different particle size has different percentage in the final material file? For example: the limestone 200TPH production line, kefid company plant design is ZSW960X3800 + PE750X1060 + PF1315, among the discharging material whose size is less than 50mm, discharging 0-6mm accounted for about 25%,6-13mm accounted for 15%, 13-19mm accounted for 25%, 19-25 accounting for 10%. But different material have different final size range, if need more technical support, please feel free to contact with our engineer.

The Stone Crushing Line Dust Removal Method is?

In a traditional stone production line, jaw crushing process has little dust and impact crushing process has large scale dust due to the powerful stone impact. Mist sprinkler equiopment should be equipped in material inlet position so as to reduce dust. The output material has not much dust after absorbing moisture in impact crushing process. Screening part no need to add water. It should be noted that the amount of water must be injected into the impact crusher in right amount. If the water is too small, there will also has dust; if the water is excessive, it will prone to clogging vibrating screen whose aperture is of 5 mm or less. Both of these action will reduce the screening effect. Some customer also choose the fans and cyclone dust collectors to remove dust, but it can not get good effect.

Crushing Machine Series

1. Ask:The advantage of wheel type mobile crusher?

Answer: There are several advantages of the wheel type mobile crusher : It is very convenient to move from the sites to sites, and do not need too much foundation; It can take less land than the stationary one; it will take less time to build at the site.

2. Ask: I want to crush limestone, which type crusher should I get?

Answer: Usually impact crusher is very suitable for crushing limestone, please kindly tell the feeding size and final size you need to confirm whether you also need primary jaw crusher and tertiary crusher.

3. Ask: What is the final size after crushed by your impact crusher?

Answer: There is not so much 50mm after crushed by our impact crusher. And you can adjust the gap between impact plate and rotor in order to control the final size. Forexample, when the raw material is limestone, 0-6mm can reach 25%, 6-12mm can reach 15%, 12-20 can reach 25%, 20-30 can reach 10%, bigger than 30mm can reach 25%.

4. Ask: Could you please recommend us a production line for highway construction?

Answer: For construction of highway, high-speed railway and hydropower, standard of concrete aggregate is very high, such as grain shape, and equipments standard, especially for crushing of basalt(Diabase, limestone). In the traditional two-step crushing, much material of flakiness shape will be generated, which will not be able to meet the very requirements. To solve this problem, we have got deep cavity vertical shaft impact crusher, JC series jaw crusher, European tech impact crusher and hydraulic cone crusher, which are specially designed to match the requirements with good grain shape and less content of flakiness materials below 5% and have successfully served many highway constructions both at home and abroad.

5. Ask: Which equipments can be used in sand making plant of your company？

Answer: The sand production line is generally composed of vibrating feeder, jaw crusher, sand making machine, vibration screen, sand washing machine, belt conveyor, assemble electricity control; In KEFID MACHINERY the full set sand production line will offer you with comprehensive technological support, the general capacity is 50-500t/h. The internationally advanced VSI crusher researched and developed by our company matched with the other series of products forms an internationally leading position in this industry.

Grinding Machine Series

1.  Ask: Please send me the price of Raymond mill to grind phosphate to 600 mesh?

Answer: According to your demand, Raymond mill is not suitable as the final size you need is very fine, HGM micro powder grinding mill is needed, the catalogue is attached, please check it. By the way, please kindly tell me the capacity you need per hour, then the best solution will be provided accordingly.

 2. Ask: Could you supply a ceramic lined mill to produce high purity silica flour? What grinding media would you recommend?

Answer: We do manufacture ceramic lined mill which can produce high purity silica flour, which grind material with ceramic balls, which is generally called ball mill. If you want more information, please contact us, we are always ready for you.

3. Ask: How about fineness of mineral powder made by mill from Kefid?

Answer: Kefid has dozens of kinds of mills and hundreds of models in total. Different mill can make mineral powder of different fineness. Kefid can provide mill to make mineral powder from 3mm into as fine as 5microns.

4. Ask: Must the air heating furnace of Vertical grinding mill be configured? How to confirm its model?

Answer: As to the natural storage materials, the air heating furnace of vertical grinding mill must be configured, unless the materials are dried. It is better to use an air heating furnace to dry the materials so that the  fine powder after grinding will be flew out quickly to improve the capacity. It is decided by the structure of grinding pan. If the wet materials are not dried, the capacity will be reduced, and it also will influence the operating stablity of the vertical grinding mill.

5. Ask: I want to grind quartz 150- 350 mesh for 2 ton per hour, which machine is suitable for me?

Answer: If you need the final product without iron , I recommend you ball mill . if there is no demand of the iron content in the final product, I recommend you our TGM grinding mill , which is lower investment cost and operation cost.
