Mineral milling is the process of grinding minerals into a fine powder. It is different from the process of granulation or crushing which is about the reduction of the size of a mineral to the size of a grain. Before milling a mineral, it is important to first determine its characteristics which include its hardness, brittleness, toughness, stickiness, melting or softening temperature, structure, abrasiveness, chemical stability, purity, homogeneity, free moisture content and structure.

The hardness of the mineral determines the specialization as well as cost of the type of mill that will be used. Brittleness is the ease with which a material will break. The free moisture content of a mineral should be low in order to ensure that the milling process takes place without any problems while the size and the degree of fineness of the mineral is required in order to know which mill to use.

There are various types of mills that can be used in the milling process including roller mills, hammer mills, pin mills, turbo mills, ball mills and vibrating mills. Each type of mill has different features and it is suitable for milling minerals with specific characteristics. For example, autogenous mills mill minerals that are fairly coarse into products that are relatively fine.

Mining of substances like minerals is usually done on a large scale and from many meters underneath the ground. The material mined are very heavy and brining them up in this status could require a lot of very heavy machines and in most cases they can’t with stand the weight so they spoil fast. Technology has made al this easier by providing milling options and it’s called mineral milling. As the professional manufacturer of complete sets of mining machinery, such as sand washer, Henan Hongxing is always doing the best in products and service. ball mill：http://www.hx-crushers.com/

Mineral milling is whereby grinding machines are used to grind the raw materials to finer forms for easy transport. Also even for easy means for transforming to an end product. This process is reversible to those particles that are not fine enough. Solid matter are ground using string mechanical forces that are used to trench internal forces that are holding the material together and break them. There are other grinding mineral millings that are used to produce manufacturing products.

Mineral milling is mainly done by large companies since it requires a lot of big machineries which are very expensive to purchase as an individual. These machines are usually transported in pieces and then they are reassembled at the plant where they will be used to grind. Each machine has a manual to help determine how each material can be grinded. This is because different rotation power is required to be used. Different mediums are also used to grind different raw materials. All these requires trained personnel to ensure the machines are working and are well maintained.
