Features of Cement Ball Mill/Grinding Mill/Roller Mill :

1)Double-row self-aligning spherical roller bearing replaces babbit-lined bearing. Friction resistance is greatly lowered down, easy to start and 20-30% of energy is saved.

2)Grooved and ringed liner increases contacting surface between balls and ores, improving milling effect and saving energy through its lifting effect to the materials.

3)All-in-one frame is used in middle-sized or small-sized machinery, facilitating engineering construction and equipment installation.

4)Large discharging outlet and high capacity,discharge coarse particles,usually used in first stage milling.

5)It can be used for grinding particles in the process of metal mineral resouces, such as gold, silver, iron, copper, lead, zinc etc., and non-metal mineral resources.

Application of Cement Ball Mill/Grinding Mill/Roller Mill :

The Energy Saving ball mill is a key equipment to grind the crushed materials, and the ball mill is widely used in powder-making production line including cement, silicate, new-type building material, refractory material, fertilizer, ore dressing of ferrous metal and non-ferrous metal, glass ceramics, etc, and the ball mill can grind various ores and other materials with dry type and wet type. There are two kinds of ball mill, grate type and overfall type due to different ways of discharging material.

Working Principle of Cement Ball Mill/Grinding Mill/Roller Mill :

This machine changes the intrinsic grinding machine structure. Its body and ground plank are an integral whole, so when fixing, it can be lowered on a plane surface once only. Using double tiered roller axletree with centripetal spherical surface as the support of the host axletree can reduce energy cost by 30%.The intrinsic grille pattern forcing evacuation is instead by overfall pattern controlling one. It can improve the milling of the granule and the capacity be increased by 15-20%.

Structure of Cement Ball Mill/Grinding Mill/Roller Mill :

The machine is composed by feeding part, discharging part, rotation part and driving part (reducer, small driving gear, electric motor and electric control). The quill shaft adopts cast steel part and the liner is detachable. The rotation big gearwheel is made by cast hobbling processing and the drum is equipped with wear-resistant liner, which has good wear-resistance. The machine is with stable and reliable working condition.

Basic Principle of Steel Ball Selection:

1.The diameter of the steel ball is mainly based on the hardness of the materials. If the ball mill has large diameter, it will has huge impact, so we can choose the smaller steel ball.

2. The small ball mill uses double storehouse clapboard should have smaller steel ball compared with the single one.

3. Generally, we keep to the level four principles, there are little large and small steel balls, that is, we mainly use middle size as the grinding medium.
