High pressure olle mil is a kind of simple structure. Reliable performance can be broken, ultra-fine broken operation can control the fineness of Modulus of equipment.The company in the design of special consideration of the market for hard material c-rushing requirements, relative to other high-pressure Roller Mill, crushing capacity is greatly enhanced. Suitable for fine crushing of medium hard materials with compre-ssive strength less than 250MPA and moisture content less than 8%. Such as river pebbles, ceramic raw materials, quartz stone, limestone, slag, feldspar and other solid materials. The machine has the features of low maintenance cost. high crushing ratio,reliable performance, small vibration, less dust and low noise. The high pressure roler mill can also be used for fine crushing of materials below medium hardness in industrial sectors such as mineral processing, electric power, chemical industry cement, Refractory. Abrasives, construction, etc. especially in building materials, power lindustry to produce Guamishi, coal gangue and other products, there is more excellentthan the general high-pressure roller mill, but also can be widely used in the crush-ing industry.

Principle of High Pressure Roller Grinding Sand Making Machineand lts Difference from Roller Grinding Machine

Many people mistakenly believe that high pressure roller mills have the same disadvantages as traditional roller mills. in essence, high pressure roller mills are fundament

ally different from traditional roller mills.

Firstly, the high-pressure roller mill is a type of roller with high pressure andlow speed, which is used for laminating and crushing stones; A roller crusher is a high-speed operation of rollers, a hammer crushing method, and an iron stone crusher. The quasi-static pressure crushing method of the high-pressure roller grinding sand machine saves about 30% of energy consumption compared to the impact crushing method ofthe roller machine;

Secondly, the high-pressure roller mill performs layer crushing on materials, which involves mutual crushing between materials. There is a large gap between the two rollers, resulting in a high throughput and output; There is no gap between the two rollers of the roller machine, resulting in significant wear and tear. The crushing efficiency of high-pressure roller grinding sand making machine is significantly improved comparedto traditional roller crushing and rod grinding techniques, with wear reduced by more than 50% lt also has a large throughput, high output, and good particle size. The squeezing stress between materials can be automatically adjusted by hydraulic cylinder pressure. The entire roller grinding process is achieved through two rollers rotating in opposite directions, with one roller fixed and the other roller movable.

Advantages of the product

1、Equipment in the sand making industry can increase production by 30% -40% and reducetotal energy consumption by 20%-30%.

2、The structure is simple and reasonable, the operating cost is low, the operation issmooth, efficient and energy-saving, the crushing efficiency is high, and the crushingratio is large.

3、Compact structure, light weight, small volume, and easy operation and maintenance. For sand making systems with the same production capacity requirements, hydraulic roller crushers can significantly save investment.

4、The roller crusher is equipped with a hydraulic safety protection device. When unexpected metal or iron parts enter the crushing chamber and exceed the set rated pressure protection device, the iron parts will leak out and the equipment will operate normally.

5、 The gap between the roller body of the roller crusher can be adjusted arbitrarily between 1mm and 20mm. After adjusting the gap according to the requirements of the crushing particle size, the crushing particle size can be reliably controlled and discharged from below the crushing chamber at the ideal particle size.
