Three roll Mill

The full hydraulic three-roll mill is applied in the printing ink,paint and other similar chemcial products,all of which are of

Features of the three-roll mill

We are professional manufacturer of hydraulic three roller machine, hydraulic system adopt PLC to control, ensure the accuracy of the roller pressure, and the left and the right pressure balance, so that material to be more uniform and smooth. Ultra thin wall of the roller, Can make the roller intermediate small height,the roller cooling water in small height, the effect is more obvious.

The welding type structure is adopted by the frame.The highly hard and cold molded alloy roll cylinder is driven and rotated by motor.The cylinder,gearing wheel and belt pulley are adjusted by dynamic balance so it operates with the lowest noise.The advanced double cylinder is designed for hydraulic system and the key hydraulic parts are chosen from Parker(U.S.A).So the mill has the advantages that it is highly sensitive in movement and its hydralic is greatly reliable.When the cooling water stops or temperature of the cylinder is too high or the current overloads or something drops into the cylinders ,the mill will stop automatically.The highly sensitive super-sonic sensor can watch the materials surface and the system will stop working when the quantity of the material is below the level of material surface designed.In this way,the safety of equipments can be guaranteed.

The three-roll mill is able to match feeder,bead mill,etc. to be the efficient and continuous processing uit.

  

The three-roll mills working principle

  

1. Each cylinder is matched with independent cooling system,which is accurately controlled.The working temperature required by the material can be set and kept evenly and steadily.2.  There are three operation positions for the three rolls of the three rolls:Each other separated for cleaningTwo rolls are clamped,the third one is separated for mixing the material.Three rolls are clamped for dispersing and discharging.The fineness of the roll in the SGG-1300 full hydraulic three-roll millRoll grinder with high fineness and laser barrelling measurer with high definition ensure that the rolls middle or high smoothness level can reach m level.
