A jaw crusher is a robust, essential and rugged crusher used primarily in mining and construction for the initial crushing of large rocks and ore. Positioned at the start of the crushing process, it uses compressive force between two jaw plates to break down large materials into smaller, manageable pieces.
The attack on rolls for fine-crushing by tube-mills, etc., is to my mind justifiable, since, below 20-mesh, the capacity of the roll becomes too small for general mill-practice, in proportion to its installation- and operating-cost; and the capacity diminishes very rapidly with the fineness of the crushing.
The purpose of the primary crusher is to reduce the ROM ore to a size amenable for feeding the secondary crusher or the SAG mill grinding circuit. The ratio of reduction through a primary crusher can be up to about 8:1. Feed: ROM up to 1.5 m. Product: -300mm (for transport) to -200mm (for SAG mill) Feed Rate:

There are two types of fine crushing equipment: impact crusher, VSI sand maker and double roller crusher. 1. The impact crusher is a commonly used secondary crusher, which is generally used to crush marble stones again after the jaw crusher. Using the deep cavity crushing method, the stones falling into the crushing cavity are …
The crushing process is commonly conducted in several stages. Each stage of the crushing process implements a different type of crusher to gradually reduce the size of the material. The first step is crushing the material by using larger crushers that can reduce the material into smaller sizes that will be used in the next stage. Following this, …
During the process of crushing, the crushing clearance of rolls is set to 0.6 to 2.4 times 80% passing size of feed material, and feed rate is limited so that passing rate of the material ranges 0.5 to 0.8 times the theoretical throughput capacity of the crusher, which remarkably increases the actual throughput of the roll crusher.
