188.8.131.52 Primary Crusher. Primary crushers are heavy-duty rugged machines used to crush ROM ore of 1.5 m size. These large-sized ores are reduced at the primary crushing stage for an output product dimension of 1020 cm. The common primary crushers are of jaw and gyratory types.
Apr 03, 2015 Types of crushers. Crushers are classified into three types based upon the stage of crushing they accomplish. These are i primary crusher, ii secondary crusher, and iii tertiary crusher. The primary crusher receives material directly from run of mine ROM after blasting and produces the first reduction in size.
5.1 Introduction. Gyratory crushers were invented by Charles Brown in 1877 and developed by Gates around 1881 and were referred to as a Gates crusher 1. The smaller form is described as a cone crusher. The larger crushers are normally known as primary crushers as they are designed to receive run-on-mine ROM rocks directly from the mines.
To get the fine product from the crusher. We need to pass it through three types of crushers in stage-wise. First Primary Crusher in that direct material comes from mines. Secondary crusher process the primary crusher material that already crushed at material size reduced and tertiary crusher which reduces the material size further.

Aug 11, 2021 Cone crushers tend to produce more elongated particles because of their high reduction ratios and ability of such particles to pass through the chamber unbroken. In an impact crusher, all particles are subjected to impact and the elongated particles, having a lower strength due to their thinner cross section, would be broken. Construction amp Working

Aug 01, 2019 Jaw Crusher, also known as concrete crusher, is usually used as the primary equipment for concrete crushing. It is also suitable for metallurgy, mining, construction, chemical, water conservancy and railway sectors, and used as a device for fine and medium crushing of ores and rocks with compressive strength below 250 Mpa.
The beauty of impact crushers is their versatility in terms of input material and output size. There are many different designs out there but generally speaking impact crushers can produce material from 3 down. The smaller the input material the harder it gets to crush. The output gradation can be adjusted through various settings.
