Technological Transformation Project of 1000 Ton/Hour Limestone Production Line in Nanyang, Henan
2019-08-01

After purchasing one Allis Saga MH600 cone crusher in 2016, the customer of the 1000 t/h production line technological transformation project in Nanyang, Henan, purchased two additional units of the same model in June 2019 to replace the original impact crushers, aiming to achieve economical operation of the production line while increasing the original capacity.

3 Units of MH600 Cone Crushers (Fine Crushing)

MH600 Cone Crusher
### 01 Production Line Information
- Ore Type: Limestone
- Design Capacity: 1000 tons/hour
- Product Size: 0-5mm, 5-10mm, 11-22mm, 11-28mm
- Equipment Configuration: 3 units of MH600 Cone Crushers
### 02 Project Advantages
1) Wide Applicability:
Suitable for crushing various ores including limestone, dolomite, granite, basalt, tuff, diabase, etc., with hardness ranging from 80MPa to 200MPa.
2) High Reliability:
Liner replacement is required only once every six months; lubricating oil and filter elements are replaced at regular intervals; weekly inspections are conducted, ensuring trouble-free operation.
3) Low Operating Costs:
- The power consumption per ton of products is only one-third of that of conventional impact crushers;
- Saves nearly RMB 4 million in electricity fees annually;
- The replacement frequency of wear parts is half that of conventional impact crushers;
- Reduces maintenance workload by 50%, ensuring continuous production.

### 03 Customer Testimonial
Compared with conventional impact crushers, the MH600 cone crusher delivers similar particle shape, significantly lower power consumption, simple operation, and low maintenance costs. Although the initial investment is slightly higher than that of impact crushers, the savings in electricity fees are extremely considerable, far exceeding the equipment purchase cost. Therefore, two additional units of the same model were purchased to replace the original equipment.
### 04 Equipment Overview
Allis Saga’s MH/MS series cone crushers are mainly used for secondary crushing, fine crushing, and ultra-fine crushing in mining, construction (aggregates), and industrial (slag, etc.) applications.
They are suitable for processing materials ranging from relatively brittle limestone to extremely hard chert, and from relatively coarse ballast to finer manufactured sand. Whether for fixed crushing or mobile crushing plants in metal mines, and for applications from conventional crushing to autogenous mill pebble crushing, the MS & MH series cone crushers deliver exceptional performance in secondary, fine, and ultra-fine crushing operations.
Featuring a single-cylinder hydraulic design, the MH and MS cone crushers are simple, reliable, efficient, and fully automatic. They feature easy operation and maintenance, lower operating costs, and superior crushed product quality, making them highly adaptable to a wide range of crushing conditions.

### Performance Features
1. Wide Applicability
Suitable for various crushing applications such as secondary crushing, fine crushing, and ultra-fine crushing in mining, construction, and industrial sectors.
2. High Reliability
Through continuous optimization and innovation, product structure, material quality, and assembly processes have all been enhanced. Combined with the independently developed advanced CIS automatic control system, the reliability of equipment is guaranteed.
3. Easy Operation and Maintenance
- The CIS automatic control system allows operators to monitor the crusher’s operating parameters in real time, minimizing downtime and labor costs.
- The positive-pressure air sealing system, combined with the internal sealing structure of the crusher, minimizes damage from fine particles and dust, extending its service life and reducing maintenance workload.
- The optimized design of components such as the hydraulic station makes operation and maintenance simpler, easier, and safer.
