ROITECH horizontal screens for efficient classification of abrasive ores
ROITECH RT-HS series horizontal screens were put into operation at the processing plant in Kazakhstan. The equipment is successfully used in the processing of chrome ore, a material with high density and increased abrasiveness.
ROITECH has produced 2 RT-HS series horizontal screens made of high-strength steel. The equipment is optimally suited for wet screening processes, where high classification efficiency is critical, as well as resistance to wear and adhesion of the screening surface.
Scope of delivery and design features
The following products were produced for the enterprise:
- RT-HSS1836 screen with a capacity of 160 t/h;
- RT-HSS2448 screen with a capacity of 280 t/h, designed for simultaneous operation with two classes of material.
A special feature of the RT-HSS 2448 screen is the split screening surface: the loading and unloading are completely independent for the two streams – the ferrosilicon slurry and the tailings.
Taking into account the different bulk densities of the materials, the body and walls of the screen were additionally reinforced to a thickness of 12 mm.
Engineering adaptation to the existing line
One of the key requirements of the customer was the integration of the equipment into the existing technological chain without modification of the supporting metal structures and foundations.
Despite the strict restrictions on geometry and configuration, additional solutions were implemented in the design to increase the reliability of the equipment:
- lining of areas of increased wear with polyurethane with a thickness of 6 mm, which is especially important when working in wet screening conditions.
- A redesigned type of fasteners that simplifies maintenance and reduces downtime.
Proven Performance in Real-World Conditions
The screens have been designed and manufactured with high precision, in full compliance with the specified dimensions and reliability requirements. The customer received a solution that does not require additional costs for adaptation of production and works efficiently in difficult operating conditions.
The equipment has already passed the stage of commissioning at the enterprise: the units have been checked, the modes have been set up and the load tests have been carried out. The screens have successfully reached the design indicators and demonstrate stable operation.
Successful operation is confirmed by a repeat order – ROITECH has already started production of two similar screens for this customer.
ROITECH vibration equipment is a solution for the classification, separation and dewatering of materials in mining and processing plants and related industries. The portfolio includes screens (extra-heavy, standard and ETO solutions for specific tasks), as well as vibration exciters and centrifuges.
ROITECH screens are designed to withstand high impact and abrasive loads and combine:
• Robust construction – high-strength steel, wall thickness up to 22 mm, HUCK bolt connections;
• capacity – up to 15,000 t/h;
• Screening efficiency – up to 98%.
The ROITECH Power System allows you to abandon the vibration isolation frame, reduce the load on the foundation and ensure smooth operation of the equipment, reducing operating costs by up to 20%.
ROITECH SmartSystem intelligent monitoring with digital twin elements allows you to monitor the status of equipment and loads in real time.
More than 200 units of vibration equipment were delivered in Russia, Kazakhstan and Uzbekistan. Production sites are in China, South Africa and Turkey.
