Dec 26, 2015 Primary crushers are designed so that the maximum size that can be presented to the crusher is approximately 80% of the gape. Jaw crushers are operated to produce a size reduction ratio between 4 1 and 9 1. Gyratory crushers can produce size reduction ratios over a somewhat larger range of 3 1 to 10 1.
Apr 18, 2018 These primary daughter fragments are given as the primary breakage distribution parameter set bij. The bij give the weight fraction of size j material which is broken to size i as a result of primary breakage. Daughter fragment material can in turn bypass through the crusher or be selected for another fracture, with a fraction ai broken.

Jan 17, 2014 There are five crushers consisting of primary crusher, secondary crusher, tertiary crusher, and two crawler crushers at this crushing facility. The ore coming from the quarry is passed from the grid with a clearance of 150 mm and the material above a grain size of 150 mm are conveyed to jaw crusher with a capacity of 400 tonne/h.
Sep 21, 2021 The output fragments of the jaw crushers are then fed to conical crushers and impact crushers depending on the desired products. Two different crushers are used for primary crushing. One of the crushers is coded as K07 with the sizes of 1100850 and the other is K11 with the size of 13001100.
a) Primary crusher The raw material from mines is processed first in primary crushers. The input of these crushers is relatively wider and the output products are coarser in size. Example - Jaw crusher, Gyratory crusher, Impact Crushers, etc. b) Secondary crusher- The crushed rocks from primary crusher are sent to these secondary

When choosing crusher machines, a comparison should be conducted according to different situations. Generally, jaw crusher is used for primary crushing, and for second crushing or fine crushing, a large ore-dressing plant always chooses the cone crusher, and a medium or small plant chooses the impact crusher. Comparison of investment cost
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 81. Feed ROM up to 1.5 m. Product -300mm (for transport) to -200mm (for SAG mill) Feed Rate
Thanks to its robust and resistant structure, the crusher is designed for primary crushing of casted convertor slag. The largest iron pieces are removed from the slag at the previous devices, then it goes through entry gratings and separation screens. The technical parameters of crushers, size and stiffness of the structure may be adjusted ...
In any operation that incorporates size reduction, selecting the primary crusher is vital to the overall success. The main parameters to first decide on a general type of crusher are the impact strength, product size and material hardness. The final design for a crusher will be selected primarily based on required capacity, feed and product size.
