Because the mineral resources development and utilization of available resources,decreases, resulting in ore mining taste gradually reduced, smelting and other subsequent processing of mineral products is also increasing quality requirements. At the same time,the human environmental protection consciousness strengthens day by day. The reality has put forward higher requirements on mineral processing equipment, prompting themineral processing equipment continuously to develop more, better and efficient energy saving direction.

Introduction

Development of mineral processing equipment and beneficiation process is synchronous,technology is the leading, equipment is the foundation. The birth of a new type of mineral processing equipment, often bring technological transformation. The technical level of equipment is not only the premise of the technical level, but also directly affects the smoothproduction process and application. The progress of science and technology, the scienceof mutual integration of mutual infiltration and among industries emerge in an endless stream, new structure, new material, new technology and new processing technology,electromechanical integration and the extensive application of automatic control technology, promote innovation of mineral processing equipment and to high efficiency and energy saving direction.

The 3 way of dressing

Edit

There are many kinds of mineral processing equipment, dry, wet separation, gravity separation, magnetic separation, flotation and so on many kinds of mineral processing method. The following is the introduction of different dressing method:

Selected iron: 1, 2, ore crushing; grinding process; 3, beneficiation technology; 4, sintering and pelletizing technology;

Choose manganese: mechanical selecting (including dressing, screening, gravity separation, high intensity magnetic separation and flotation separation), and Deputy setfire method, chemical processing method etc..

Chromium selecting: first use jump titanium machine, shaking table, spiral separator,centrifugal separator and belt chute beneficiation, also use hydraulic sorting don't havetable middlings

Choose titanium vanadium magnetite: in the period of it by grinding, a coarse, fine, asweep of the magnetic separation flowsheet of magnetic separation of magnetite concentrates after a magnetic tail.

Selection of copper flotation, magnetic separation, gravity separation: or wet methods such as smelting.

Selection of lead and zinc: combined beneficiation general magnetic - floating, floating,heavy - weight - magnetic - floating method.

Aluminum: choose general selected by hand.

Nickel: 1 election, flotation; 2, using crushing, pre screening processes to remove differentiation is weak, low bulk nickel containing bedrock.

Selected cobalt: general use of flotation.

Choose tungsten ore types: according to tungsten wolframite and scheelite is divided into.Processing methods are hand selected, gravity separation, flotation, magnetic separation,and electrostatic separation method.

Select SN: mineral processing method for gravity separation, flotation process.

Molybdenum: mainly flotation method.

Selected mercury: a hand selected, gravity separation and flotation, which is widely used to flotation is the most effective.

Choose sb: mainly hand selected, gravity concentration, flotation method.

Choose platinum: 1, the reasonable milling, the use of appropriate cyclone classification; 2,recovery rate;

Gold: gold in mineral content is extremely low, the extraction of gold ore crushing and grinding needs to be dressing method by using the gold separation. Is mainly the gravity separation and flotation.

Selection of silver: 1, the combined process of flotation; 2, a single flotation and flotationgravity separation, flotation cyanidation method, of which the most important in flotation.

Selection of niobium and tantalum lithium beryllium: hand picking method, the flotation method, chemical or chemical - the flotation method, warm election law, choice of law,radioactive particle flotation method.

The most common method of selecting SR: she witherite celestite beneficiation, the most popular structure process is in jigging - wave as the main body of the process.

Rare metal: choose general concentrate containing rare earth oxides by about 60% usingmagnetic separation, flotation

Boiling type concentrator uses centrifugal force to sedimentation flotation jumped a newtitanium addition of mineral processing equipment miscellaneous recovery rate up to 99%

Ball mill

After the ball mill is the material being broken, and then smash the key equipment.

Mineral processing equipment

Ball mill is one of the high fine mechanical grinding is widely used in industrial production.

There are many kinds, such as handball mill, ball mill, ceramic ball mill, ball mill bearing,energy saving ball mill, the overflow type ball mill, ball mill, ball mill enamel.
