Metallic and Nonmetallic Ore Crushing and Powdering Production Line
Mining machinery and equipment in the crushing, pulverizing, beneficiation process with the development of the mining economy, has gradually highlighted its dominant position. At present, China's mining production is mainly for a variety of metal and non-metallic ores for a series of crushing, milling, beneficiation and other processes, including ore crushing, milling is widely used.
There are many ways to classify minerals, the current commonly used classification method has three kinds of industrial classification, genesis classification and crystal chemical classification. According to the different properties and uses of minerals, the industrial classification of minerals, divided into metal minerals and non-metallic minerals. According to the cause of minerals, minerals are classified into three categories: endogenous cause minerals, exogenous cause minerals and metamorphic cause minerals. According to the chemical composition and crystal structure of minerals, minerals are divided into five categories, namely, natural elements, sulfides and their analogues, oxides and hydroxides, oxygen-containing salts and halides.
In the processing of metallic and nonmetallic ore beneficiation plant, crushing and grinding undertake the task of providing candidate materials for subsequent sorting operations. Sent from the mining ore dressing plant is the upper limit of the raw ore particle size 1500-lOOOmm (open pit mining) to 600-400mm (underground mining) of the loose mixed particle group, and the selection requirements of the candidate particle size is usually 0.2 -0.1mm or finer, which suggests that the crushing and grinding process is to reduce the particle size of the process is for the subsequent selection operation to provide materials.
A variety of powdering, beneficiation production process, in production are affected by the particle size, that is to say, too coarse particle size selection can not be up, too fine particle size is also difficult to recover. It is worth noting that. Grinding products in the coarse particle size there is the opportunity to be ground again (if it is a closed-circuit grinding or more than two grinding). And over-crushed minerals have no chance of recovery. It can be said that over-crushing not only increases the power consumption and steel consumption in the grinding process, but also deteriorates the selection process and causes a waste of mineral resources, in the grinding process should minimize the generation of over-crushing particle size.
Crushing, grinding two production processes interact with each other, carry on the next, for the development of grinding, powder industry plays a key role. Users in the purchase of powder production line during the mining machinery manufacturers to give the production program is particularly important, the user to read carefully, a set of excellent production line configuration, but also need your pair of eyes. Various types of crushing, grinding, beneficiation production program, you can click on the website customer service immediately consulting, we will provide you with a professional technical team for your service, 24 hours online.
