Test apparatus of crusher

Abstract

The invention discloses a test apparatus of a crusher. The test apparatus comprises a test motor, a mobile mechanism and a fixation mechanism. The output end of the test motor is sleeved by a main belt wheel, the mobile mechanism comprises an installation plate, the test motor is flatly placed on the installation plate, the installation plate is provided with rollers for movement, and the installation plate is provided with support bars; and the fixation mechanism comprises bases, each base comprises a base slope section, a base intermediate section and a base rear section, the base intermediate sections and the base slope sections are provided with tracks for movement of the rollers, at the same time, the depth of each track ranges from one fourth to one third of the diameter of each roller, the joint positions between base rear sections and the base intermediate sections are hinged to arc-shaped cover plates for fixing the rollers, and the arc-shaped cover plates are fixed to the base intermediate sections through fixation pins. According to the invention, whether a crushing rotor is stably installed after assembling can be tested, and an inner liner of the crusher is prevented from severe wear caused by a quartering hammer due to shake of the crushing rotor.

Description

technical field [0001] The invention relates to the field of correcting devices for crushers, in particular to testing devices for crushers. Background technique [0002] Mining crushers are also called stone crushers, which refer to crushing machines in which the particle size of the discharge is greater than 3mm, accounting for more than 50% of the total discharge volume; mining crushers are widely used in mining, smelting, building materials, roads, railways, Many departments such as water conservancy and chemical industry. [0003] Existing mining crushers include hammer crushers, jaw crushers, etc., wherein the hammer crusher is mainly composed of a crusher shell, a feed chamber located on the upper part of the crusher shell, a crushing chamber located in the middle of the crusher shell and a crushing chamber located in the middle of the crusher shell. The screening room at the lower part of the crusher shell is composed of; and the crushing rotor in the crushing chamb...

Problems solved by technology

[0003] Existing mining crushers include hammer crushers, jaw crushers, etc., wherein the hammer crusher is mainly composed of a crusher shell, a feed chamber located on the upper part of the crusher shell, a crushing chamber located in the middle of the crusher shell and a crushing chamber located in the middle of the crusher shell. The screening room at the lower part of the crusher shell is composed of; and the crushing rotor in the crushing chamber is the core of the crusher; since the crushing rotor works in a high-speed environment, it will generate strong centrifugal force, and the stability requirements for the crushing rotor are very strict. If the crushing rotor Due to the unbalanced placement position, when rotating at high speed, it is very easy to cause the crushing rotor to shake, so that the crushing hammer connected to the crushing rotor will cause serious wear to the inner lining of the crusher, and the crushing effect is not ideal.
