Double-roll crusher with rollers with fixed shaft support structure

Abstract

The invention belongs to the technical field of crushers, and in particular relates to a counter-roll crusher with grinding rollers with a fixed-axis support structure. The invention includes a crusher frame, the crusher frame is provided with a fixed roller part and a movable roller part, a crushing discharge port is formed between the fixed roller part and the movable roller part, and the crusher frame is provided with There are drivers. In the present invention, by setting the discharge port adjustment component, when crushing ore of different sizes, the discharge port adjustment component drives the moving roller part to move to the end close to or away from the fixed roller part, so as to adjust the size of the crushing discharge port, which can reduce the work intensity of the staff. , Precisely adjust the size of the discharge port, ensure that the size of the discharge port is consistent within the full length of the roller, and maintain the crushing discharge port, which can overcome the disadvantages of traditional models that cannot crush hard ores, and can be used in the production of metal mines, greatly reducing The cost of crushing metal mines, and at the same time, it can pass through the iron regulator during crushing. Accurately determine whether the iron is too high to ensure the safety of the equipment.

Description

technical field [0001] The invention belongs to the technical field of crushers, and relates to a pair-roll crusher with grinding rollers with a fixed-axis support structure. Background technique [0002] At present, the domestic equipment used for construction waste crushing mainly includes jaw crusher, hammer crusher, impact crusher, roller crusher, etc., and jaw crusher is the preferred equipment for pre-crushing construction waste. Crusher, impact crusher and roller crusher are suitable for the production of segment sand, and are used for secondary crushing of bulky materials obtained by primary crushing, classification and screening of construction waste. Traditional roller crushers are generally only used for construction aggregate production, and are difficult to be used for ore crushing in metal mines. The crushing cost of metal mines is high, and it is difficult to accurately determine whether iron is over, which cannot guarantee the safety of equipment. [0003] I...

Problems solved by technology

However, this solution is not suitable for ore crushing in metal mines, which makes the crushing cost of metal mines still high, and it is difficult to accurately judge whether the iron is too high, and there is a defect that the safety of the equipment cannot be guaranteed.
