Properties and uses of the aggregate crushing machine

The aggregate crusher has been widely used for crushing job of various ores in industrial sectors such as cement, building materials, coal and chemical as well as beneficiation industry; it is also can be used as coarse crushing equipment. The reasons for the rapid development of aggregate quarry crushing plant lie in the following important features:

  • (1) Great breaking ratio. Usually, the crushing ratio of ordinary crusher does not exceed 10, while aggregate crusher crushing ratio is generally 30-40, and even can be up to 150, thus greatly simplifying the production process and saving investment costs.
  • (2) High crushing efficiency and low power consumption. Having been affected by the high speed function and repeated impact of blow board, the ore along powder jointed interface and the part of organizational vulnerability is first broken. So the kind of crusher has high efficiency and low power consumption.
  • (3) Uniform particle size and less over-crushing phenomenon. The kinetic energy of ore is proportional to its nature; so in the ore crushing process, larger block gets a greater degree breaking and smaller ore will be not broken under certain conditions. Therefore, the particle size is uniform and it produces over-crushing phenomenon barely.
  • (4) Selective breaking. In crushing process, useful minerals and gangue first ruptures along the jointed surface, facilitating useful minerals achieve monomer separation.
  • (5) Strong adaptability. This crusher enables to crush brittle, fibrous, medium and below hard ores, particularly suitable for limestone and other brittle ore crushing. Cement and chemical industries adopting aggregate crusher is appropriate.
  • (6) The equipment has small size, light weight, simple structure, easy manufacturing and easy maintenance.

Peculiar Features and Application of Overflow grinding Mill

According to the different ore discharging method, SBM grinding mill can be divided into lattice grinding grinder and overflow grinding mill which is the most widely used ore grinder in the current iron ore concentration plant. Inside the cylinder of overflow grinding mill, a certain amount of steel grindings are loaded as the ore grinding medium. Materials are crushed and grinded by the steel grinding grindings and then discharged out of the machine through the hollow shaft neck at the ore discharging end. As the ground products are overflowly discharged from the hollow shaft neck, this type of grinding mill machine is called overflow grinding mill which is widely used in various industries.

An overflow grinding mill machine is mainly composed of cylindrical cylinder, end cap, bearing and driving gear ring. The internal cylinder is covered by wear-resisting lining boards fastened with bolts. Inside the cylinder, there are grinding media which are usually steel grinding grindings. When the main motor drives, the internal steel grindings will stick onto the lining boards and rotate with the cylinder under inertia, centrifugal force and frictional force. After being brought to a certain height, under the gravity, the steel grindings will fall down. The falling steel grindings will form fierce impact force on the ores. In the meantime, steel grinding grindings will rotate around the cylinder axis and produce squeezing and grinding force on the ores among the steel grindings and in the contact area of the cylinder, thus crushing and grinding the ores to complete the grinding process.

Overflow grinding mill is a crushing mill working under the wet state. The biggest difference from the dry type grinding mill is that the end cap is taper type, and on the end cap, there is only one crest lining board. The overflow grinding aking machine produced by SBM adopts high-quality lining board made of high manganese, with high wear resistance, low noise and high working efficiency. The biggest advantage of our overflow grinding mill is that it is able to separate low-grade magnetic iron ore with high precision, choose any granularity and get rid of coarse tailings at any time. This equipment has low investment and quick effect. It is mainly used in industrial production, especially in the ore beneficiation industry.
