    Lattice ball mill is the key equipment for crushing materials. The ball mill is widely used in cement, silicate products, new building materials, refractory materials, fertilizers, ferrous and non-ferrous metal beneficiation, and glass ceramics. It is used for dry or wet grinding of various ores and other grindable materials. .

    

    Working principle of lattice ball mill

    This machine is a horizontal cylindrical rotating device, driven by external gears, two bins, lattice ball mill. The material enters the first silo of the mill spirally through the feeding device through the hollow shaft of the feeding material. There is a stepped lining or a corrugated lining in the hopper, which contains steel balls of different specifications. The centrifugal force generated by the rotation of the cylinder brings the steel balls to a certain height. After falling, it has a heavy impact and grinding effect on the material. After the material is coarsely ground in the first bin, it enters the second bin through a single-layer compartment board. This bin is inlaid with a flat liner and steel balls inside to further grind the material. The powder is discharged through the discharge grate plate to complete the grinding operation.

    Internal structure of lattice ball mill

    Performance advantages of lattice ball mill

     Good spindle performance and high throughput

    The main bearing uses a large-diameter double-row self-aligning stick bearing instead of the original sliding bearing, which reduces friction and energy consumption, and the mill is easy to start.

    The structure of the end cover of the ordinary mill is retained, and the large-diameter inlet and outlet ports have a large processing capacity.

     Simple structure and smooth operation

    The feeder is divided into a combined feeder and a drum feeder, which has a simple structure and is installed separately.

    There is no inertial impact, the equipment runs smoothly, and the mill shutdown and maintenance time is reduced, and the efficiency is improved.

    Solving Method of Lattice Ball Mill's Empty Shaft Lubrication

    The diameter of the place where the rolling bearing is mounted on the hollow shaft of the bearing lattice ball mill is thickened, and the thin oil cooled by the hollow shaft of the lattice ball mill reduces the temperature of the hollow shaft to the bearing within the normal range below 60 °. The advantages of this bearing seat are as follows:

    1. Thin oil lubrication is superior to grease lubrication, which reduces the friction coefficient of the bearing and saves electricity better.

    2. The normal operating temperature of the bearing is much lower than that of dry oil lubricated bearings, which prolongs the service life of the bearing.

    3. There is an oil level observation oil level in the lower seat of the bearing. The operator can see the oil level at any time, and can replenish the oil quantity in time to prevent poor lubrication due to lack of oil and avoid bearing damage.
