Symons Cone Crusher Feed

The‍‌‍‍‌ dilemma you may be facing is as follows: The machine's output always lags behind the expected level. If the discharge opening is made smaller then the output drops even more; when it is enlarged the particle size of the product goes bad. Over and over again you have to trade-off the output for the quality and in the end cannot reach either of them.

Resolution: The main principle of the enhanced cone crusher is the multilayer crushing method - crushing is done through mutual compression of material layers within the crushing zone without the liner plate impact.

① Stroke length increase of 18%~25% — By refining the eccentricity of the eccentric sleeve's inner hole along with the tolerance dimensions of the spherical bearing of the main shaft the moving cone's oscillation amplitude per revolution goes up thus each rotation processes more material

② Meshing angle decreased by 2°~4° — Reducing the angle formed between the upper and lower walls of the crushing chamber lowers material slipping, improves grabbing force, and raises the production rate

③ Parallel zone extension of the working space by 15~20% — the longer working space near the discharge allows the material to stay in the chamber for a while, which improves the fine crushing capacity and the ratio of the finished products meeting the requirement.

Performance: Taking the ZYS-5.5FT used for processing medium-hard limestone as an example, if the production capacity of the old model was only 220~250 t/h then after improvement the one tested was 280~310 t/h, which is about a 25% ‍‌‍‍‌increase.

Features

‍‌‍‍‌

1. Adjust structure of the crushing chamber to optimize the processing capacity per unit time and enable continuous highly-efficient mining and crushing at the operation site.

2. Great appearance of the finished particles: Using the principle of successive crushing, the cubic particles ratio is largely increased and the content of the slender particles and the flakes is reduced; such product will better comply with the specifications of the high ways, high speed railways and commercial concrete aggregates.

3. More wearing parts life: By using high-manganese steel, high-chromium wear-resistant materials together with dry sealing system, not only can the dust be prevented from entering into the bearing system, but also the service life of main parts and frequency of maintenance are reduced.

4. Stable, dependable and consistent running: Main unit is built of high-strength steel casting, making it ideal for prolonged crushing of hard materials (compression strength ≤350MPa) such as granite, basalt and Iron ore.

5. Less stoppage: The system of hydraulic unloading rapidly removes blockage of materials, so that the time spent by men disassembling and the machine running get both decreased, thereby giving an improved total run time.

6. Less power use: The crushing chamber structure and eccentricity optimized reduce unit power consumption but do not sacrifice output, which helps customers cut long running costs.

Frequently Asked Questions (FAQ)

Q: What is the Minimum Order Quantity (MOQ)? Do you accept large procurement?

A: Definitely. We offer a wide range of ordering options:

Standard Products: MOQ is 1 pc.

Non-standard Custom Parts: MOQ is from 2–5 pcs/batch, according as complexity (negotiable).

Long-Term Framework Agreements: For purchases over 5M yuan annually, we offer an Annual Price Lock-In Agreement. This agreement protects your costs against any variation of the price of steel throughout the year. Besides this, your delivery cycle will be reduced from the standard 45 days to 7–10 days through our service of "Reserved Raw Material Stockpiling" which means we prepare custom blanks in advance for you.

Q: Which packaging methods do you adopt in order to prevent product damage during transport?

A: Product safety takes precedence with us.

In typical, product packaging consists of:

Accessories: Wrapped in strong wooden boxes for secure storage.

Large Pieces & Complete Machines: Enclosed in channel steel frames that have been custom-welded for complete protection, wrapped with protective foam and waterproof film to shield the product from any kind of damage whether it is from impacts, bumps or moisture during transportation.

Q: Which logistics and shipping terms does your company support?

A: We currently support EXW (Ex Works) and FOB (Free On Board) modes of trading.

Kindly inform us about the one you prefer, and we will ensure to arrange the optimal supply ‍‌‍‍‌solution.
