1. Rubber liners physical density is only about one-sixth of manganese steel, it greatly reduces the weight of ball mill, so when the rubber lining ball mill works, it needs lower the power. Saving electric energy means saving production cost and investment.

3. Low noise. Rubber itself has function of soundproofing, it reduces the noise when rubber liner ball mill works. In a certain way inspires the enthusiasm of the staff, indirectly improves the enterprises production efficiency.

5. Rubber liner ball mill also has features of corrosion resistance. Manganese steel liners create reactions with acid, alkali, salt and other chemicals, it accelerates the wearing of liner, while rubber liner itself is made by special anti-corrosion, thereby extending wearing time.

6. Rubber liner ball mill also saves grinding media. Based on the actual work estimates, compared with manganese steel liner, mineral processing plant with capacity of 100,000 tons per year, rubber linings can save 150,000 tons steel balls.

Normal life time for rubber liner ball mill 1. in the gold ore mill, lining life time reaches 3 to 4 years 2. in the ceramic industry, rubber lining life can be used up to 5 years 3. in cement industry, rubber liner ball mill liners can be used up to 4 years

Ball milling is a size reduction technique that uses media in a rotating cylindrical chamber to mill materials to a fine powder. As the chamber rotates, the media is lifted up on the rising side and then cascades down from near the top of the chamber. With this motion, the particles in between the media and chamber walls are reduced in size by both impact and abrasion. In ball milling, the desired particle size is achieved by controlling the time, applied energy, and the size and density of the grinding media. The optimal milling occurs at a critical speed. Ball mills can operate in either a wet or dry state. While milling without any added liquid is commonplace, adding water or other liquids can produce the finest particles and provide a ready-to-use dispersion at the same time.

Grinding media comes in many shapes and types with each having its own specific properties and advantages. Key properties of grinding media include composition, hardness, size and density. Some common types include alumina, stainless steel, yttria stabilized zirconia and sand. Ball milling will result in a ball curve particle size distribution with one or more peaks. Screening may be required to remove over or undersized materials.

Ball mills are also classified by the nature of the discharge. They may be simple trunnion over-flow mills, operated in open or closed circuit, or grate discharge (low-level discharge) mills. The latter type is fitted with discharge grates between the cylindrical mill body and the discharge trunnion. The pulp can flow freely through the openings in the grate and is then lifted up to the level of the discharge trunnion. These mills have a lower pulp level than overflow mills, thus reducing the dwell time of particles in the mill. Very little over grinding takes place and the product contains a large fraction of coarse material, which is returned to the mill by some form of classifying device. Closed-circuit grinding, with high circulating loads, produces a closely sized end product and a high output per unit volume compared with open circuit grinding. Grate discharge mills usually take a coarser feed than overflow mills and are not required to grind so finely, the main reason being that with many small balls forming the charge the grate open area plugs very quickly. The trunnion overflow mill is the simplest to operate and is used for most ball mill applications, especially for fine grinding and regrinding. Energy consumption is said to be about 15% less than that of a grate discharge mill of the same size, although the grinding efficiencies of the two mills are the same.

Particular care is taken when processing furnace linings, graphite crucibles and borax slag containing metallic gold and silver. Not only do we homogenize the by-product materials by crushing to reduce the particle size to less than 10 mm (1/4 inch) in size for sampling purposes, we proceed to feed the crushed materials through a rubber lined, vibratory, ball mill. We reduce the material size to less than minus 60 mesh.

The jaw crusher reduces the slag as it passes through the crushing plates. Feeding action is moving the material through the crusher. The cheek plates reduce material instantly, most of it to spec size. Feeding action is moving the material from a hopper to the crusher.

In processing materials such as slags, crucibles, furnace linings, etc. the gold and silver minerals must be released from the surrounding host before the gold and silver minerals can be captured during the sampling process.

Milling: Particular care is taken when processing furnace linings, graphite crucibles and borax slag containing metallic gold and silver.

We reduce the material size to less than minus 60 mesh. All of the material are screened through a Sweco vibratory screen, separating the metallic oversize from the milled material. The metallic oversize is melted in the JRI induction furnaces.

Just Refiners has the capacity to crush 10 tons of borax slag to minus half inch per day. Each batch of slag is weighed before sampling. The mine, or a representative of the mine is present during weigh-in and sampling. After crushing the entire lot of borax slag, it is passed through a 3 tier riffle splitter to obtain a representative sample for evaluation purposes. The customer receives a sealed sample to have their materials analyzed independently.

Just Refiners (USA) Inc was incorporated in 1993. Just Refiners is situated in Sparks, Nevada and is currently expanding into processing spent carbon in house. The main core of Just Refiners is to provide a service to the mining industry by receiving, preparing, sampling, and processing their by-product materials.
