Product overview

Roller press is a pre grinding equipment for cement and mining grinding systems, which has the advantages of reducing power consumption, increasing production, saving investment, and easy operation and maintenance. Its energy-saving, environmentally friendly, and convenient development towards large-scale direction have been unanimously recognized by the industry. With the implementation of national energy-saving and emission reduction policies, roller presses have been widely used in the cement industry, especially in the mining sector. The roller press in the grinding system adopts a roller press based on material layer grinding technology and a matching powder selector that integrates dispersion, grading, and drying. It can be combined with ball mills or form its own system to form various process flows, such as pre grinding, mixed grinding, semi final grinding, and final powder grinding systems. Due to changes in the grinding mechanism, the "Pengfei" roller press and its system technology can reduce energy consumption by 20-50% and increase production by 30-70% in the grinding system.

Application area

In the mining field, roller presses mainly replace cone crushers for fine crushing or ball mills for coarse crushing. Due to the high technological content of mining roller presses, enterprises need to have strong independent research and innovation capabilities. Pengfei Group is committed to providing the best solutions for grinding systems in cement, mining and other fields. The "Pengfei" roller press grinding technology has rapidly expanded from the cement industry to the mining industry, achieving breakthrough growth in its application in the mining industry.

FEATURES

The wear resistance of roller surface materials is a key factor determining the application of roller presses. With the continuous breakthrough of roller surface material wear resistance, roller presses are gradually expanding from the field of cement grinding to various metal ore grinding fields. The application proportion of roller presses in the field of cement clinker grinding is about 20%. In the field of mining grinding, the application of roller presses is just beginning. The ore grinding of nearly ten thousand metal mines and metallurgical enterprises in China is the key demand for roller presses for sales in the future. High pressure roller mills will be increasingly widely used in the mining industry. The roller press has obvious advantages in energy saving, consumption reduction, and efficiency improvement, which is superior to traditional production processes. Compared with traditional crushers, roller presses can save 20% -50% electricity, with significant energy-saving effects; Increase production by 30% -70% and improve the production efficiency of the system; It can save civil engineering investment, facilitate the transformation of the original grinding system, and facilitate the development of enterprises towards large-scale direction.

Advantages of high-pressure roller mill

Flexible configuration: The process system has flexible configuration and strong adaptability.
Large crushing ratio: can crush iron ore with a diameter of ≤ 60mm to ≤ 3mm.
Wear resistance of roller surface: The roller surface has high hardness, strong wear resistance, and long service life.
Large processing capacity: The single machine processing capacity of the high-pressure roller mill can reach 50-2500t/h.
Environmentally friendly and efficient: The equipment has low noise and dust pollution, the rollers run smoothly, and the effective utilization rate reaches over 95%.
Energy saving: The high-pressure roller mill ultra fine crushing process replaces the traditional crushing grinding process, reducing total energy consumption by more than 50%.
Steel consumption reduction: The high-pressure roller mill ultra fine crushing process replaces the traditional crushing grinding process, reducing total steel consumption by more than 40%.
Widely applicable: High pressure roller mills based on the principle of material bed crushing are ideal equipment for achieving energy conservation and consumption reduction, which is conducive to the large-scale, high-efficiency, energy-saving and automation development of mineral processing technology. They have become the main equipment for ore crushing and grinding systems

Characteristic comparison

Compared with traditional processes, the ultra fine crushing of ores significantly saves electricity and steel consumption, has a large crushing ratio, a large single machine processing capacity, a wider product particle size distribution, and more fine powder, effectively improving the recovery rate of extremely poor iron ores and the quality of iron coarse powder. It has a high dynamic conversion rate, low operating costs, and significantly reduces production costs. The pellet feeding is finely ground, and the unit electricity consumption is significantly reduced compared to the wet mill. It greatly increases the specific surface area of iron fine powder, effectively improves the fineness and balling quality of iron fine powder, significantly enhances production capacity, has a high operating rate, low operating costs, and significantly reduces production costs. Metal ores are dissociated, selectively crushed, and the bed grinding technology is used to squeeze lean ores, greatly improving the recovery rate. A large number of microcracks promote leaching. Liquid entry and mineral dissociation are beneficial for dissociating target minerals before re-election or flotation.
