The structure of the overflow ball mill is basically the same as that of the lattice ball mill, except that there is no discharge lattice at the discharging end of the cylinder. Furthermore, the surface of the hollow journal bushing is equipped with an inverse spiral blade, which can return the spilt balls and coarse ores from the slurry to the mill. The grinding product of the overflow ball mill is free overflow through the discharge hollow journal. For this reason, the level of slurry in the cylinder must be higher than the lowest busbar level of the discharge shaft neck.
Overflow Type Ball Mill
Overflow Type Ball Mill Overview:
The main component of wet overflow ball mill is a cylinder with bigger diameter and smaller length which is revolved by transmitting machinery. Materials are put in cylinder through the feed opening and then thoroughly grinded. The falling course of iron balls and ores can produce huge falling impact and autogenous grinding.
Overflow Type Ball Mill Features:
1. The jack-up device of wet grate ball mill makes maintenance easy.
2. The hydrostatic and hydrodynamic bearings ensure the smooth operation of wet grate ball mill.
3. The low speed transmission of wet grate ball mill contributes to easy overhaul and maintenance.
4. The oil-mist lubrication device guarantees reliable performance of bearings.
5. The gas clutch adopts the flexible start-up model.
Working Principle :
Principle of overflow ball mill: the main component is a cylinder with diameter and length at a reasonable proportion. Driven by the transmission device, the cylinder rotates with the materials fed from the cylinder inlet and crushed by the falling impacts and autogenous grinding of the steel balls and ores in the cylinder. Due to the continuously feeding materials, the pressure pushes materials to the outlet and the grinded materials are discharged from the cylinder outlet. Qualified materials flow from the cylinder outlet. In wet grinding, the materials are taken out by the water flow. There are backpitch impellers in the hollow shaft, which can make the balls and coarse ores in the overflow return to the mill. With simple structure, higher operation rate, and rolling bearing, the energy conservation is significant.
¡¾Overview of Overflow Type Ball Mill:
Normally, overflow type ball mill adopts wet production structure, which is one of the most widely used ball mill equipments. The finished ore pulp is discharged from the output end by flooding and with a high capacity. Besides, we add grinding head sieve in the grinding end for preventing big materials and grinding mediums from discharging.
Compared with grid ball mill, the ore grinding time of over-flow type mill during production is longer, which makes ore grinded more fully in the machine. And the grinding products granularity is finer and the unit capacity is little less than the grate ball mill of same type. It is generally applicated in the secondary grinding work. Flow type ball mill is composed of shell, head, bearing, driving parts, gearwheel and feeding and discharging devices.
Besides, our company manufactured over-flow type ball mills with different dealing abilities and types of liner plate. Our products types are the most completed and products applications are the most widely in China. We are the manufacture with the most types of products, which can satisfy customers different requirements for ore production.
¡¾Working principle of Overflow Type Ball Mill:
The ball mill is horizontal cylindrical rotation device, driven by brim gearwheel. There are two chambers and grid. Material goes into the first chamber through the feeding inlet. Inside the first chamber, there are stage liners and ripple liners as well as steel balls. The shell rotates so as to generate electricity, and this force brings ball to a certain height and then balls drop down by gravity, the impact is the grinding force to the material. After the primary grinding, materials go into the second chamber through segregate screen. In the second chamber, there are flat liners and steel ball, after the secondary grinding, material is discharged from the discharging.
¡¾Features of Overflow Type Ball Mill:
1. Wide usage, simple structure, convenient maintenance;
2. Big capacity, continuous working;
3. Body liners and grinding medium could be made of various of materials, good corrosion resistance,;
4. Easy installation, adjustment, and operation

Mill scale, is formed on the outer surfaces of plates, sheets or profiles when they are being produced by rolling hot iron or steel billets in rolling or steel mills.
It looks like a hard brittle sand and is mainly composed of iron oxides, mostly ferric, and is bluish black in color.
Being produced during the reheating, conditioning and hot rolling operation for the production of steel articles, the mill scale initially adheres to the steel surface and protects it from atmospheric corrosion, provided no break occurs in this coating.
From the chemical and physical analysis performed on the scrap, and according to the european environmental rules, the material has been classified as a special non dangerous waste, listed in green list
In particular the mill scale can be classified as follows:
Einecs (european commission no.): 266-007-8
Waste code: 10 02 10
Basel code: b 12 30
Hs code: 2619.00
We are glad to propose 500 MT of stain less steel mill scale.
Mill scale is formed on the outer surfaces during by the hot rolling lamination of stainless-steel products.
At a visual inspection the material is a hard brittle sand and is mainly composed of iron oxides, mostly ferric, and is bluish black in colour, but it also contains considerable alloying elements such as chromium and nickel.
The recovery ratio after melting in furnace for the most valuable alloy elements is:
- Ni: 3.5 - 4.5%
- Cr: 6-8%
From the chemical and physical analysis performed on the scrap, and according to the European environmental rules, the material has been classified as a special non dangerous waste, listed in green list. In particular the mill scale can be classified as follows:
Waste code: 10 02 10
The material is stored on cemented flooring, and it can be loaded loose in tipper trucks or containers.
Chemical analysis of the material is available on request.
