 Plastic mixing mill machine

 

 

Machine Overview:

 

Two roll Mixing Mills are designed to ensure perfect and uniform blending of natural and synthetic rubber with other raw materials. These mills provide uniform mixing of the material to the desired level. Most of the mixing mills are driven by electronic motor and different models have different output

 

Main features:

 

Roll bearing

Two rigid pillars with removable tops carry the rolls, which are placed either in friction/bush bearings or high quality anti-friction roller bearings. Roller bearings are pretty much standard nowadays, as they allow for 20 – 30 % in power-savings. A lubrication system is no longer required.

 

Roll nip setting

Adjustment of the front roll used to be made by hand (manual by ratchet) or later motorized by worm gear.

 

Nowadays hydraulic pistons adjust the rolls and also protect rolls from high forces that can build up in between the rolls (roll safety). They also open roll gap immediately when pushing the safety bar in front or back in case of emergency (required by European Safety standards CE).

 

Rolls

A mixing mill has 2 horizontal rolls set up back to back. They are made of ground chilled cast iron, with surface hardness ranging from 475 – 520 HV (Vickers hardness) up to 520 – 580 HV (or 68 - 72 HSD). The depth of hardened layer ranges from 10 to 16 mm.

 

Rolls are made with a central bore for cooling through a spray-type lance (low cost type cooling) or peripheral drills, where bores are closer to the surface for better cooling and more equal distribution.

 

The rotary joints connected to the spraying lance are supplied from tempering units to provide constant temperature during the mixing process.

 

Material Guides or Compound guides

At the ends of the roll faces the roll nip is being limited by the compound guide cheeks. The compound guide cheeks of split design with “centre tongue” avoid lateral escape of compound from the working area in any case.

 

Friction

The standard drive provides fixed speed and fixed friction ratio. The front roll typically runs slower than the back roll. Depending on the compound mixed the friction can range from 1:1.1 for a standard mixing mill, 1:1.25 for silicone or plastics mills, 1:1.8 for breaker mills for new rubber, 1:2.5 for refiner mills with narrow gap of 0.05 mm, up to 1:3.2 for breaker mills for old rubber. A variable speed motor on each roll is required for infinitely variable friction ratio.

Version : xk-160 xk-230 xk-250 xk-300 xk-360 xk-400 xk-450 xk-560

 

Certificate and identification: ISO 9001, CE , SGS

Application : The mill is used for rubber plasticating, mixing, warming and sheeting.

General design:

1. The mill consists mainly for rolls, frame, bearing, roll nip adjusting, screw, heating and cooling device, emergency stop, lubrication system and such sections as electrical controls and, etc.

2. The main electric motor arrives the front and rear rolls to rotate oppositely through reduar, driving geras and friction gears.

Features:                                                                                                       

1. The rolls are made of chilled alloyed castiron. Their working surfaces are of high hardness and wear-resistant. The working temperature of the bored roll is controllable by steam, cooling water or oil that pass through them thus, to meet the requirements of milling process.

2. Roll nip adjustment is realized by hand or electricity which can obtain high accuracy and sensitivity

 

Others                                                                                                         

 

Roller bearing can be divided into 3 kinds, nylon bush , bearing bush and copper bush .

Nip adjustment can be divided into manual and electric .

Stock blender can be added in light of your needs
