The primary impact crushers are used to process from 200 t/h up to 1900 t/h and feed sizes of up to 1830 mm (71") in the largest model. Primary impact crushers are generally used in nonabrasive applications and where the production of fines is not a problem. Of all primary crushers, the impactor is the crusher that gives the best cubical product.
The primary crusher mainly refers to the jaw crusher and impact crusher. They reduce 1.5 meter feed to approximately 10-20 cm particles.In the designing of a crushing plant of any nature and size, to select the right type and size of primary gyratory crusher is of great significance. Generally speaking, this machine is the largest and most ...
Jaw Crushers 7 The BB 50 is designed for a very efficient and convenient size reduction pro-cess. The variable speed can be set between 550 and 950 min-1 to adapt the crushing process to sample requirements. The possibility to reverse the rotat- ing direction is helpful if too much sample material has been fed to the crusher causing it to block.
A gyratory crusher is one of the main types of primary crushers in a mine or ore processing plant. Gyratory crushers are designated in size either by the gape and mantle diameter or by the size of the receiving opening. Gyratory crushers can be used for primary or secondary crushing.

Primary and Secondary DDC-Sizers feature a unique hydraulic product size adjustment, which allows producers versatility if the product size requirements change. This feature allows producers not only the option of maintaining original size specifications, but also gives them the ability to adjust to meet changes in product size requirements.
Figure 5.1 Schematic diagram of a crusher showingg the open- and closed-side settings. 5.1 Jaw and Gyratory Crushers. Jaw and gyratory crushers are used mostly for primary crushing. They are characterized by wide gape and narrow discharge and are designed to handle large quantities of material. The capacity of the crusher is determined by its size.
All Shumar Crushers have two machined rolls to which the crusher segments are bolted. Each Roll is generally fitted with six crusher segments; some large roll diameter primary crushers do have more segments per roll. Manganese Steel segments are used in all Primary …
How you select your primary crusher will be based on factors like moisture content, maximum rock lump size, material density SG, abrasion index, degradability and it being prone to dusting or not. The crusher capacities given by manufacturers are typically in tons of 2,000 lbs. and are based on crushing limestone weighing loose about 2,700 lbs. per yard3 and having a specific gravity of 2.6.
22.214.171.124 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 10–20 cm. The common primary crushers are of jaw and gyratory types.

Primary Plant is an export led company and has been a leading exporter of both new and used mobile crushing and screening equipment throughout the world since its inception.
The raw coal in the power generation station is generally at 300mm, usually adopting coal sizer crusher as primary crusher, and ring hammer crusher, four tooth roll crusher or reversible hammer crusher as secondary crusher, to crushing the raw coal to be 10-30mm for the fuel of circulating fluidized bedboiler or the raw material of coal powder ...
Primary Impact Crushers are preferred for their high performance on crushing soft character substances like gypsum & limestone. Their huge feeding capacity and adjustable closed side settings control the crushing process. Due to the working principle of crushing, degradation ratio is higher than the jaw crushers.
Apr 03, 2015· 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.
