Diamond introduction

The diamond is an extremely rare mineral composed of pure carbon. It is well known for its extreme hardness, brilliance, and thermal and electrical characteristics. Natural diamond has been discovered in approximately 35 different countries. Because of their beauty and physical characteristics, diamonds have been regarded as symbols of love, beauty and eternity.The following countries produce industrial grade diamonds: Australia, Botswana, Brazil, China, Congo, Russia and South Africa.

The application of diamond

Because it is the hardest substance known, diamond will cut through any material. The principal use of diamonds is in jewellery, with the market increasing over 250% over the past 15 years. However, not all diamonds are of gem quality, in fact most diamond deposits contain a varying proportion of industrial and gem quality stones.

Diamond crushing process

in diamond crushing and grinding process, the most commonly used crushers and grinding mills are jaw crusher, cone crusher, hammer crusher and ball mill, ultrafine grinding mill, etc. It is usually a complete production line for diamond crushing.

Diamond crushing begins with the communition of extracted ore in preparation for further activities to achieve ore values. Crushing operations are designed to produce uniform size particles by crushing, grinding,and wet or dry classification. The capital investment and operation costs of milling equipment are high. For this reason, it is important for us to choose the suitable crushing equipment. Factors that decide the choosing of crushing machine include the value concentration of the ore, its mineralogy, hardness, and moisture content.

Crushing is a multistaged process and may use dry or wet ore feed. Typically, primary crushing take place at the mine site. Primary crushing is accomplished by using jaw crusher or cone crushers. Primary crushing yields chunks of ore ranging in size from 6 to 10 inches.Oversize material is passed through additional crushers and classifiers to achieve the desired particle size. The ore is then crushed and sized at a secondary milling facility.

Jaw crusher for diamond: Jaw crusher is used in primary crushing station. It can crush diamond into smaller sizes. Thus, these small diamond can be fed into mill such as ball mill for grinding.

impact crusher is generally used after jaw crusher, and can crush hard stones, not only the diamond, but also other ores such as copper, bauxite, antimony, Kaolinite, gold etc.

Secondary milling (comminution) further reduces particle size and prepares the ore for beneficiation processes that require finely ground ore feed. The product gold ore from this additional crushing is usually less than 1 inch (1/2 to 3/4 inches). Secondary crushing, if necessary and economical, is accomplished by using standard cone crushers or impact crusher.

Cone crusher is the most common fine crusher, and usually used as final crushing machine. It has four types: spring cone crusher, CS cone crusher, hydraulic cone crusher, hcs90 cone crusher. Each cone crusher has their different applications.

Subsequent fine grinding further reduces the ore particles to the consistency of fine powder (325 mesh,0.0017 inches, 0.44 microns). The choice of grinding circuit is based on the density and hardness of the ore to be ground.Ball mill was used as diamond grinding mill. In diamond concentrator, it was used to grind diamond into fine powder.

Vibrating diamond feeder and screening machine used in diamond crushing process

Vibrating diamond feeder is used to feed diamond evenly to diamond crushing and grinding machine.

Vibrating diamond screen is the screening machine. It screens out the appropriate diamond particles, these particles enter into ball mill for grinding.
