Double Roller crusher is a commonly used medium and fine crushing equipment

The roller crusher is a medium-to-fine crushing device commonly used for crushing raw materials in construction materials, mining, chemical, cement, refractory and other industries. The crushed material of the roller crusher is crushed by a roll and ground to crush the material. The crushing roller is in direct contact with the material and is prone to wear. It is a consumable part and is a part that needs to be repaired during use. When purchasing a roller crusher, experienced customers often ask for more information about the crusher, such as what the crusher is, how long the crusher can be used, and how to replace the crusher. Currently, there are two types of roll crusher crushing rolls on the market. One is a high manganese steel casting roll and the other is a carbon steel casting roll. Currently, most roller crusher manufacturers use high manganese steel casting rolls and there are fewer manufacturers using surface rolls. Gongyi Furui Machinery Factory is a manufacturer of early roll crushers using surfacing rolls. The length of use of the crushing rolls of the roller crusher varies depending on the strength of the different crushing materials, and the hard materials are destroyed and used in a short time; the broken brittle materials are used for a long time. Production practice has proved that the service life of the surfacing roll is about 2-3 times that of the high manganese steel roll.
The roller crusher is a commonly used medium and fine crushing device. The crushing and grinding action of the relatively rotating crushing rolls is the decomposition of the material, and the broken material naturally falls from the discharge port due to gravity. The speed of the crushing roller of the roller crusher affects the processing capacity of the equipment. The higher the rotational speed of the crushing roller, the larger the amount of material produced and the corresponding increase in processing capacity. The rotational speed of the crushing roller also affects the feed to the roller crusher. If the speed is too high, the material will slide between the two rollers.
