construction waste crusher

A grinding mill is a unit operation designed to break solid materials into smaller pieces. There are many types of grinding mill, such as construction waste crusher, Raymond mill, MTM trapezium grinding machine, high pressure suspension grinding mill and so on. As an ideal grinding mill for secondary crushing, construction waste crusher is an efficient pulverize machine for fine powder grinding. construction waste crusher is widely used in many fields. This durable construction waste crusher can grind many kinds of mine and other materials, such as the cement, the silicate product, new type building material, fire-proof material, chemical fertilizer, black and non-ferrous metal, glass, ceramics and etc.
The abrasion of the steel ball of construction waste crusher is an irreversible process of physics to machine and physics to chemical that happens on the surface of the solids. The abrasion of the steel ball is mainly divided into mechanical abrasion and corrosive wear these two types, and the former is caused by impact, grinding, friction and fatigue, and the latter is caused by the effects of ion and chemical agents in the rock slurry.
Mechanical abrasion: The factors that influence the mechanical abrasion include the material quality and weight of the steel ball, the size and working condition of the grinding machine, the granularity distribution of materials feeding and final products, the hardness of the rocks and the temperature of the rock slurry. Generally speaking, increasing the metal content in the steel ball will decrease the mechanical abrasion, for example, the stainless steel ball is more durable than the common carbon steel ball. The impact and grinding occurring between the steel ball and steel ball, steel ball and rock materials and steel and the lining board will be consumed with the transfer of the energy. Krushcho assumes that only about 10% to 20% of the energy consumed by the impact force is used for rock crushing. The rest energy is consumed in such aspects that lead to the abrasion and damage of the steel ball such as plastic deformation of the steel ball, metal cutting and move, transformation of the organizational structure of the steel ball, Increase of the surface residual stress, recrystallization of subsurface stratum metal.
The abrasion speed influenced by impacting and grinding is mainly determined by the impacting energy, which are the weight of the steel ball and the size of the grinding machine. In the moment of impacting touch, the touching point will produce highly concentrated stress, which will cause the plastic deformation of the surface of the steel ball, for this reason, the steel ball surface will form cracks with different shape and depth. In the rock grinding process, after the steel ball suffers several times of impacting and grinding effect, the cracks will constantly deepen and widen, and finally part of the fragment will break away from the ball.
