400 Ton/Hour High-Quality Aggregate Production Line in Northern Ireland
2019-07-24

After viewing Allis Saga’s equipment at the 2018 HILLHEAD UK Machinery Exhibition, the customer of the 400 ton/hour production line project in Northern Ireland decided to purchase equipment for its new high-quality aggregate production line designed according to top European standards.
Based on the customer’s production requirements and product size specifications, Allis Saga offered a tailored production line solution and supplied corresponding crushing equipment.

Secondary Crushing: MS300C Cone Crusher

Fine Crushing: MH300MF & MH400M Cone Crushers
#### 01 Production Line Information
- Ore Type: Coarse Sandstone, Hard Sandstone (similar to tuff in China)
- Design Capacity: 400 tons/hour
- Product Size: More than 7 sizes
- 20/32mm, 16/22mm, 10/22mm,
- 11/16mm, 8/14mm, 8/11mm,
- 6.3/10mm, 4/10mm, 5/8mm,
- 2/6.3mm, 2/5mm, 0/4mm, 0/2mm
- Equipment Configuration: MS300C + MH400MF + MH300MF
- Technological Process:
Primary crushing is carried out directly at the quarry blasting face using a mobile jaw crusher, crushing the stone to below 300mm. The crushed stone is then transported to the processing plant by mining trucks. After being discharged from the mining trucks, the material is fed to the MS300C (secondary crushing) via a feeder and a variable-speed belt to achieve full-load feeding. Fine crushing is handled by one MH400MF and one MH300MF.

### 02 Project Advantages
The production line is designed to top European standards and features an exceptionally high degree of automation (the entire processing plant is managed and operated by only 2 personnel).
### 03 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.
