V-shaped jaw crusher

Abstract

The invention relates to a V-shaped jaw crusher with a small driving angle, a large stroke, a reasonable rotate speed, and capabilities of realizing larger feeding granularity, higher yield, more uniform granularity and low jaw plate wear rate. The V-shaped jaw crusher comprises a jaw crusher. A distance between a supporting point position of a wrist plate in the jaw crusher and a suspension pointposition of a movable jaw is 1477+ / -0.5mm; a meshing angle between a fixed plate and a movable plate is alpha 22+ / -0.5 degrees; a crushing cavity is a V-shaped cavity with a lower opening and has theheight being 2100+ / -0.5mm; a feed inlet is 950+ / -0.5mm; a minimum discharge opening is 100+ / -0.5mm; a horizontal stroke of a discharge opening is 39+ / -0.5mm; and the discharge opening discharges for290 tons to 800 tons per hour. The V-shaped jaw crusher has the advantages of (1) small driving angle, large stroke and reasonable rotate speed; and (2) larger feeding granularity, higher yield, moreuniform granularity and low jaw plate wear rate.

Description

technical field [0001] The invention relates to a V-shaped cavity jaw crusher with a small transmission angle, a large stroke, and a reasonable rotating speed, which can make the feed particle size larger, the output higher, the particle size more uniform, and the jaw plate wear rate is low, which belongs to the crusher manufacturing industry. field. Background technique [0002] In terms of structural design, the traditional compound pendulum jaw crusher adopts a design with a transmission angle of about 50-52 degrees. Since the transmission angle has an impact on the movement track and transmission efficiency of the movable jaw, increasing the transmission angle will improve the transmission efficiency. , but with the increase of the transmission angle, it will lead to power loss; secondly, due to the large transmission angle, the design of the fulcrum position must be low, accounting for about 75% of the height of the crushing chamber, which will affect the stroke at the ...

[0002] In terms of structural design, the traditional compound pendulum jaw crusher adopts a design with a transmission angle of about 50-52 degrees. Since the transmission angle has an impact on the movement track and transmission efficiency of the movable jaw, increasing the transmission angle will improve the transmission efficiency. , but with the increase of the transmission angle, it will lead to power loss; secondly, due to the large transmission angle, the design of the fulcrum position must be low, accounting for about 75% of the height of the crushing chamber, which will affect the stroke at the discharge port. It has a great impact, and the stroke at the discharge port is about 28mm. According to the movement rules, it can be clearly seen that the long ellipse long track at the discharge port of the traditional jaw crusher is steeper, and the corresponding horizontal stroke will be reduced, leading to The output is reduced, about 150 tons to 310 tons per hour; the third is that due to the increase in height stroke, the rapid wear of the lower discharge port is accelerated
