Grid type ball mill

1. Stable performance

2. Equal product size

3. Low invest, low energy consumption

Working Principle of grid type ball mill

This ball mill is horizontal type and tubular running device, has two warehouses. This machine is grid type and its outside runs along gear. The material enters spirally and evenly the first warehouse of the milling machine along the input material hollow axis by input material device. In this warehouse, there is a ladder scaleboard or ripple scaleboard, and different specification steel balls are installed on the scaleboard, when the barrel body rotates and then produces centrifugal force, at this time, the steel ball is carried tosome height and falls to make the material grinding and striking. After grinded coarsely in the first warehouse, the material then enters into the second warehousefor regrinding with the steel ball and scaleboard. In the end, the powder is discharged by output material board andthe end products are completed.

The grid type ball mill

The grid type 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.

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%.

The Features and Benefits of grid type Ball 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.
