Product Description
Product Introduction:
High pressure roller grinding machine has simple structure and reliable performance.Its high pressure can grind material to fine,superfine products with the fineness modulus under control.Our company specially considered the needs for shattering rigid material in design,so the grinding machine has higher crushing capacity compared with other high pressure roller grinding machines.It is applicable to crushing material with medium and high hardness and pressure strength of lower than 250Mpa and humidity of lower than 10%, such as cobbles,coke,coal,ceramics,quartz, limestone,muddy shale,chalkstone,gypsum,edible salt and chemical material.This machine is characterized by low maintenance cost,large crushing ratio, reliable performance,small vibration,and less dust and low noise.
High pressure roller grinding machine can be used to moderately crush single-component material with high or medium density,like ore,rock and industrial slag in a wide variety of fields,such as ore dressing,electricity,chemical industry,cement,fire retardant material,grinding material and construction.In particular,it can be used to produce melon stone,coal and coal gangue in building material and electricity industry with better results than normal high pressure roller grinder.It can also be used for crushing steel grit.
Working Principle:
The roller crushing machine has two rollers rotating in the opposite position.Brittle material is sent to a weighing hopper with weighting sensor by a transference mechanism and passes through the feeding mechanism until it enters into a place between two rollers of the same sizes standing in the opposite position.The side of the roller draws the material into the roller crevice with high pressure in between,which compresses the material into compact cake-like product that drops down.The product is then moved out at the hopper by the transference mechanism,and will be separated or ground in the following process.
Product Characteristics:
1.The hydraulic system makes it easy to adjust the roller crevice while protecting the machine.
2.The roller and its surface are fitted with hard alloy studs that increase its service life by 2000-20000 hours.
Sand making process
Technology characteristics:
This technique is designed for sand making production line.The design production capacity is 50-500t/h. Advanced PYY single-cylinder hydraulic cone machine is used for secondary crushing.PCL vertical shaft impact crusher is used for sand sizing and making, specifically designed for production of artificial sand;it is characterized by good sizing, high sand making ratio,low operational cost and rational graduation.It has been successfully applied in crushing of a lot of raw materials, such as granite, basalt,cobbles,bauxite,cement clinker,quartz,emery,ores and iron ores,and the products meet the national standard of Sand Used in Construction.It finds application in many projects such as water conservancy,bridge engineering,high-grade highways and high-rise buildings.
Stone making production line
Technology characteristics:
This technique is designed for stone making production line.With large crushing ratio,high productivity,high handling capacity,uniform fineness,good sizing shape,convenient maintenance,small losses,and long service life,it has been successfully applied in crushing and processing of limestone,basalt,granite and cobbles.Crushed aggregates fully meet the national standard of Cobbles and Gravels Used in Construction,and used in such areas as high grade highways,railways,water conservancy and concrete mixing station.
Accessories Service:
The company upholds a business philosophy of "creating benefits for customers" and sticks to the principle of "service first".With professional, fast,and premium service,it offers comprehensive service services for sand making and components around the clock.
