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. The output of the primary crusher is fed to a secondary crusher, which further reduces the size of
A gyratory crusher includes a solid cone set on a revolving shaft and placed within a hollow body, which has conical or vertical sloping sides. Material is crushed when the crushing surfaces approach each other and the crushed products fall through the discharging opening. Hammer crushers are used either as a one-step primary crusher or as a secondary crusher for products from a primary crusher.
The term “secondary crushing” has become well established and familiar through long usage; it applies to the crushing stage, either single or multiple, which follows immediately after the primary crusher, taking all or a portion of the product of the primary crushing stage as its feed. The term should not be used, as it sometimes is, to designate a particular type or size of crusher
A main motion introduces a new subject for discussion and action. A main motion says: Let’s do this about that. The main motion is the starting point on the way to making a group decision. Secondary motions offer different approaches to consider in the discussion of the main motion. A secondary motion says: Let’s do that this way.

Aug 26 2015Grinding 1 Grinding and Grinding Machine 2 Grinding Grinding is a process of removing material by abrasive action of a revolving wheel on the surface of a work-piece in order to bring it to required shape and size The wheel used for performing the grinding operation is known as grinding wheel It consists of sharp crystal called
ABC Circuit: A two-stage grinding circuit composed of an Cascading: The motion of the charge in a tumbling mill which occurs when the Choke Feed: Crusher operation where the crusher cavity is kept full. . Motor power is transferred to the main shaft assembly through this .. Secondary
Table Source: Wikipedia (Crushers) Cone crushers use a spinning cone that gyrates in the bowl in an eccentric motion to crush the rock between the cone surface, referred to as the mantle, and the crusher bowl liner.Gyratory crushers are very similar to cone crushers, but have a steeper cone slope and a concave bowl surface. As the gap between the bowl liner and the mantle narrows, the rock is
A gyratory crusher includes a solid cone set on a revolving shaft and placed within a hollow body, which has conical or vertical sloping sides. Material is crushed when the crushing surfaces approach each other and the crushed products fall through the discharging opening. Hammer crushers are used either as a one-step primary crusher or as a secondary crusher for products from a primary crusher.
The moving jaw dies are mounted on a pitman that has a reciprocating motion. The jaw dies must be replaced regularly due to wear. Figure 8.1 shows two basic types of jaw crushers: single toggle and double toggle. In the single toggle jaw crusher, an eccentric shaft is installed on the top of the crusher.
Most secondary motions can be used regardless of main motion and also applies to several secondary motions. detailing a set of rules for process and conduct Milling, Shaping and Grinding

Main motion in machining Machining is any process in which a cutting tool is used to remove small chips of material from the workpiece (the workpiece is often called the "work"). To perform the operation, relative motion is required between the tool and the work. This relative motion is achieved in most machining operation by means of a primary
A main motion is a motion that brings business before the assembly. Main motions are made while no other motion is pending. Any of the subsidiary, incidental and privileged motions may be made while the main motion is pending, and in many cases these motions, if passed, will affect the assembly's consideration of the main motion.
But, part B of this one-thing-at-a-time rule does allow for secondary motions to pause the main-motion process, if needed. Using the above example again, a member could propose a delay of the parks and rec discussion by suggesting, “I move that we table the main motion regarding the parks pavilion refurbishing until there the city’s annual
Secondary motions may be subdivided into (1) subsidiary, (2) incidental, and (3) privileged. Subsidiary motions are applicable to other motions for the purpose of modifying the main question or affecting its consideration and disposition. The subsidiary motion to lay on the table is, in American usage, a motion to suspend consideration of the
Jan 25, 2019· When a meeting attendee wants to introduce a matter for consideration, a motion is made. Usually a motion needs to be seconded -- meaning another attendee agrees the matter should be considered-- to have the motion move forward and discussed. If the motion is not seconded, it is called a failed motion.Even a failed motion should be documented in the minutes, however.
Their main purpose is to reduce the material to a small enough size that it can be transported by conveyors to the next crushing stages. As the name suggest, jaw crushers reduce rock and other materials between a fixed and a moving jaw. The moving jaw is mounted on a pitman that has a reciprocating motion, and the fixed jaw stays put.

A crusher is a machine designed to reduce large rocks into smaller rocks, gravel, sand or rock dust.. Crushers may be used to reduce the size, or change the form, of waste materials so they can be more easily disposed of or recycled, or to reduce the size of a solid mix of raw materials (as in rock ore), so that pieces of different composition can be differentiated.
