Pain Points

In‍‌‍‍‌ fine crushing, the nominal capacity is different from the qualified output. If the discharge is 9 mm and the target is ≤12 mm, only about 72% of the discharge may meet the specification. Inefficient screening leads to a high percentage of coarse fines and a low efficiency in separating the size required. This results in a 178% circulating load and that the return material should not be more than 1.8 times that of qualified material. Such situation makes the generation of needle- and flake-shaped particles increase, and the energy per tonne of qualified product rise. The problem is not only the crusher capacity but also the screen efficiency and circuit balance.

Solution

The ZHP300 multi-cylinder hydraulic cone crusher is a great option for fine-crushing. A fine-crushing cavity, 8-12 mm discharge setting, and 250 kW motor, will work quite well. In case of an accidental discharge adjustment as well as overload protection and setting recovery, the crusher will take care of it thanks to its own hydraulic system. The PLC system tracks parameters like eccentric-sleeve speed, crushing pressure, oil temperature, pressure, load, and discharge-setting position of the crusher. You can use closed-circuit screening as an effective way to keep the circulating load within the target range. Remember, the quoted capacity of a crusher of 90-450 tph is the nominal capacity not the guaranteed qualified output at that setting. Calculate the qualified output circulating load and the specific energy by the full screening circuit and make material tests with representative samples to check.

Target Improvement

With these factors: feed particle size distribution, moisture content, bulk density, work index (i.e., the amount of energy required to break the rock into smaller particles), screen aperture and screen efficiency, crusher setting chamber, cavity, motor voltage/frequency, and number of operating hours, the aim is to achieve an increase in qualified production share from 72% to 85-90%, a lowering of circulating load level from 178% to 100-120%, a decrease of the specific energy requirement per unit of qualified product by up to 10-20%, and also a reduction in needle and flake shape particles.Actual performance depends on feed conditions, circuit design, and the level of operating discipline.

Verification and Acceptance

Bring the system to steady state operation and carry out a full continuous test lasting for 8 hours. Log crusher power, oil temperature, oil pressure, motor speed, CSS, feed rate, weight on return belt, weight on product belt; sampling must be conducted at regular 30-minute intervals and the sieve tests should be carried out immediately afterward. Qualified output = (mass of the product of specified size)/steady-state operating time. Circulating load = (% of material returned)/(% of new feed) X 100. Specific energy = sum of crusher, screen, and circulating conveyor energy/ mass of product of the specified size. Any agreed performance metrics should be put in a ‍‌‍‍‌contract.

Product Advantages:

1. Intelligent PLC Control

Standard‍‌‍‍‌ type of PLC/HMI is monitoring eccentric-sleeve speed, crushing pressure, lubricating oil temperature, oil pressure, motor load, CSS position and running status of the crusher.Alarm settings are programmable and can warn on overload, high oil temperature, low oil pressure and unstable crushing pressure.ZHP300: 250 kW, CSS 8-45 mm, fine cavity setting is from 8-12 ‍‌‍‍‌mm.

2. Stable Mechanical Structure

Mainshaft‍‌‍‍‌ fixed + rotating eccentric sleeve. A hydraulic system controls CSS and offers overload protection while a separate lubrication system deals with oil temperature, pressure, and flow. ZHP300: 18.6 tonnes, 250 kW, 90-450 tons/hour nominal. Noise, vibration, and failure rates are all confirmed by site measurement or agreed test ‍‌‍‍‌data.

3. Laminated Crushing Technology
The‍‌‍‍‌ crushing process inside this type of crushing chamber involves two major crushing mechanisms: compression and inter-particle laminated crushing, which result from the mantle and concave surfaces moving against each other, without generating impacts. A matched cavity and CSS (closed-side setting) together with the right kind and size distribution of the material (fed), and the proper amount of circulating load will allow the crusher to give consistently good particle shape and a controlled amount of recirculation. To confirm this, we ran an 8-hour steady-state test, sampling was done every 30 minutes, and we carried out sieve analysis, flakiness/elongation testing as well. Standards compliance necessitates the standard test number and a test ‍‌‍‍‌report.

4. Medium/Fine Cavity Conversion
Cavities‍‌‍‍‌ of medium and fine are open for use. The changing over from one to the other involves the replacement of concave, mantle, and bowl liner along with other spare parts. The CSS needs to be reset and the hydraulic - lubrication - related systems to be checked up. It is the preventive planned maintenance; there is neither the automatic or on-load switching.

The ZHP300 cavity has a fine cavity type with an 8–12 mm CSS, 250 kW of power, and a capacity of nomination from 90 to 450 tons per hour, but in actual fact 18.6 tons are used. Capacity factor, product size, power consumption, and wear characteristics were independently confirmed for cavities and applications ‍‌‍‍‌respectively.

Product Application:

ZY/ZHP: secondary, tertiary, and fine crushing of hard/medium-hard materials.

Gold ore: ZHP300, 250 kW, feed 240 mm, 18.6 t; nominal 90–450 t/h at CSS 8–45 mm. For CSS 8–12 mm: fine cavity + closed-circuit screening. Reference: discharge ≤12 mm = 72%; circulating load 178% (return/fresh feed, including near-size particles returned by screening); return ≈1.8× qualified. Verify qualified output by sieve analysis + circuit calculation.

Granite/basalt aggregate: ZHP100–ZHP800, 90–630 kW, 50–1220 t/h nominal, CSS 6–60 mm. Closed circuit controls flake content.

Metal ore before grinding: ZHP300/ZHP400, 250–315 kW, 90–645 t/h nominal. Verify qualified output and specific energy by test.

Solid waste: hard/medium-hard, low-moisture, low-contamination only; CSS 8–45 mm; test required.

Compliance depends on target spec, local standard, screen aperture, and test results.

Note: reference operating conditions, not customer case studies.

Comprehensive Quality Control System

The‍‌‍‍‌ company has a well-developed quality management system, which includes the processes for purchase of raw material, manufacturing, heat treatment, assembly, and finally, inspection at the factory. Inspections are consistent with the relevant industry standards and approved technical drawings. Major inspections carried out during production are verification of incoming material certification and chemical analysis, checking of heat treatment quality (via hardness and microstructure), mechanical properties (tensile, yield, and elongation), thread accuracy verification, critical dimension tolerance checks, and assembly compatibility verification. Product specifications sampled prior to delivery are mainly hardness, tensile strength, thread machining accuracy, and assembly performance.

Reports can be provided on material certificates, heat treatment records, checking of dimensional data, assembly records, and third-party inspections if requested.

Through rigorous quality controls, we guarantee that products operate effectively in challenging mining environments with features such as long-term high load and high vibration. This not only minimizes the errors at the installation site but also decreases the risk of equipment breakdowns and prolongs the life of ‍‌‍‍‌products.
