Automatic classification jaw crusher and application method

Abstract

The invention belongs to the technical field of crushers, and particularly relates to an automatic classification jaw crusher. The jaw crusher comprises a movable jaw, a main fixed jaw, a multi-stagefixed jaw, a power mechanism, a reciprocating mechanism, a vibration mechanism and a rack, wherein the movable jaw, the main fixed jaw, the power mechanism, the reciprocating mechanism and the vibration mechanism are all arranged on the rack. The crusher disclosed by the invention can classify stones according to sizes before the stones are crushed, and crushes the stones according to the sizes ofthe stones; the movable jaw swings once to crush the stones for multiple times; and after the stones are crushed for multiple times, flaky stones can be reduced. The invention further provides an application method of the crusher. The application method comprises the steps of adjusting a second crushing gap, locking the second crushing gap, swinging the movable jaw, vibrating the main fixed jaw and the like. The method is convenient to operate, simple and easy to understand and high in automation degree, the stone size classification standard can be changed, classified crushing is conducted according to the stone size, the crushing efficiency is high, the crushing effect is good, and the operability is high.

Description

technical field [0001] The invention belongs to the technical field of crushers, and in particular relates to an automatic sorting jaw crusher and a usage method. Background technique [0002] Jaw crushers are widely used in mining and smelting, building materials, highways, railways, water conservancy and chemical industries to crush various ores and bulk materials. The working parts include static jaws and movable jaws. The static jaws are vertical or the upper end is slightly outward. The ground is fixed on the front wall of the machine body, and the position of the movable jaw is skewed, forming a crushing cavity with a large upper part and a smaller lower part with the static jaw. Driven by the eccentric shaft (main shaft), the movable jaw reciprocates periodically relative to the static jaw, sometimes separating and sometimes approaching, simulating the movement of the two jaws of animals to complete the material crushing operation. The movable jaw is installed on the...

Problems solved by technology

[0009] Aiming at the above-mentioned deficiencies in the prior art, the present invention provides a jaw crusher with automatic classification, which is used to solve the problem that the existing jaw crushers in the prior art cannot classify stones by size before crushing them, and Crushing is carried out according to the size of the stone; the existing jaw crusher can only crush the stone once with one movement of the motorized jaw, and the crushing efficiency is low; the stone after crushing by the existing jaw crusher is easy to become flakes, and the crushing quality is low; and, The jaw plate of the existing jaw crusher is not uniformly worn, and it needs to be replaced up and down, which consumes manpower, material resources, time and cost, and the utilization rate of the jaw plate is insufficient. The present invention also provides the use method of the crusher.
