Jaw crusher

Abstract

The invention provides a jaw crusher, and relates to the technical field of crushing equipment. The jaw crusher solves the technical problem of a limited granularity adjustment range. The jaw crushercomprises a rack, a movable jaw, a fixed jaw, a rotary driving device, a first toothed plate, a second toothed plate and a pushing device. The movable jaw and the fixed jaw are oppositely arranged onthe rack, a crushing area is formed between the movable jaw and the fixed jaw, and the first toothed plate and the second toothed plate are arranged on the sides, opposite to each other, of the fixedjaw and the movable jaw respectively; the rotary driving device is in transmission connection with the upper portion of the movable jaw and is used for driving the movable jaw to move close to, away from and up and down relative to the fixed jaw; and one end of the pushing device is fixed to the rack, and the other end of the pushing device rotationally abuts against the lower portion of the movable jaw. The jaw crusher also comprises a distance reducing assembly arranged between the fixed jaw and the first toothed plate, and the width of the crushing area between the movable jaw and the fixedjaw is reduced through the reducing assembly. The jaw crusher is used for material crushing, can adjust the discharge particle size through the distance reducing assembly, and has the characteristicof being large in adjustment range because the distance reducing assembly is arranged on one side of the fixed jaw.

Description

technical field [0001] The invention relates to the technical field of crushing equipment, in particular to a jaw crusher. Background technique [0002] Jaw crusher is the most commonly used crusher. It is widely used in mining, metallurgy, construction, chemical industry and other departments to crush hard and medium hard materials. Machines are widely used because of their simple structure, reliable operation, easy manufacture, convenient maintenance and low cost. In the existing construction waste disposal line, the first process is to use a jaw crusher for primary crushing. This link is very important and directly affects the efficiency of subsequent processes. In the compound pendulum jaw crusher commonly used in the market at present, the movable jaw is directly suspended on the eccentric shaft and directly driven by the eccentric shaft. The bottom of the movable jaw is supported on the rear wall of the machine frame with a thrust bracket. When the eccentric shaft r...
