Crushing ratio competition of different crushers

When it come to the field of barite crushing machine, we may be familiar with one phrase crushing ratio. So, what exactly does this mean? How to caculate this ratio? What is the mineral's largest size and how to measure it? Here we're going to make it more clear in detail. Crushing ratio refers to the average number of pieces the raw feed rock is reduced into. Usually, there are two kinds of crushing ratio, one is total crushing ratio, the other is gradual crushing ratio; the former one equals the multiplication of different gradual crushing ratio.

The impact crusher operates much in the same method as a single impeller, with counter-rotating (two) impellers which not only impel the material against the breaker bars, but also impel material high inside the chamber to be fractured on other incoming feed. Uses impact to crush material.

The roll crusher is a crusher that breaks material by squeezing it between two revolving metal cylinders, with axes parallel to each other and separated by a space equal to the desired maximum size of the finished product. Uses compression to crush material. There are also triple roll crushers able to handle larger feed sizes. They also produce fewer fines per pass than do cone type crushers. Roll crushers are good for producing road chips. Not recommended for abrasive rock, but very good crushing limestone.

A hammer crusher is a crusher that employs hammers or flails on a rapidly rotating axis. The hammers are usually made of manganese. Uses impact and attrition to crush material. These series products is character as high crushing ratio, uniform production, simple structure, reliable function, easy maintenance, economical working and so on. We use the superior to make the main part, especially the perishable parts.

Detailed explanation of ore grinding process

In the ore grinding process, the most widely used machine is cylinder grinding mill whose grinding process goes like this: materials are sent to the continuously rotating cylinder in which there are a certain amount of grinding bodies with different shapes, like balls, rods, short columns, large ores and gravels. When the barrel rotates with a certain speed, these grinding media will be pushed to produce impacting and grinding force to grind the materials. For this reason, the crushing force of cylinder grinding mill comes from the external force that are exercised to the grinding body and transmit the crushing force to the materials to be grinded.

Generally speaking, grinding is to get fine particles or super-fine products. Other than cylinder ore grinding mill which can also be called media mill, the grinding force of some machines can be directly put on the crushed materials to get products with fine granularity, so this also belongs to the grinding field, such as Raymond mill, colloid mill and air-flow mill. The ore grinding process directly influences the technical indexes of the ore beneficiation plant, for example, the weak single separation degree of useful minerals will reduce the grade of concentrate and the recovery rate; or over crushing or over grinding will not only increase the consumption of electricity and steel, but aggravate the beneficiation process and reduce the beneficiation index. According to the fineness differences of the final products, the ore grinding process can be divided into: 1. coarse grinding: the granularity of the final products is 0.15~3.0mm; 2. fine grinding: the granularity of the final products is 0.02~0.15mm; 3. superfine grinding: the granularity of the final products is small than 10um and even 0.05~1um.

Technical efficiency improvement of the stone grinding plant

In the stone grinding production line or stone grinding plant, to improve the technical efficiency means much for the improvement of ore beneficiation indicators. So how can we improve the technical efficiency of the SBM grinding plant? The answer is to adopt the closed circuit grinding technological process.

The reasonable grinding flow means that mineral grains should be discharged quickly from the grinder once they are ground and separated. For the existing stone grinders, its very difficult to realize the material grain gradation. Therefore, we usually adopt the classifier or fine screener to gain the qualified granularity grade and those coarse material grains will return to the grinding machine again. This process is called sand return.

In the closed circuit grinding flow, the grinder will add returning sand to the new materials. When more materials pass through the grinding machine, the grinder will run faster and the grinding time will be shortened. The closed circuit grinding process requires the unqualified materials moves into and out of the grinding machine again and again till they become qualified ones.

With a large amount of coarse sand fed into the grinder, the closed circuit grinding flow increases the coarse fraction content of the feeding materials. Besides, the proper sand return will remove the vibration of the new materials and bad influence on the granularity of minerals.
