{"id":131,"count":692,"description":"These crushers are used as a primary stage of aggregate size reduction due to the large feed opening. For these crushers we offer a large range of wear parts to cover all the main needs :\r\n<ul>\r\n \t<li>Swing jaws or mantles<\/li>\r\n \t<li>Fixed jaws or concave segments<\/li>\r\n \t<li>Fastening items<\/li>\r\n \t<li>Fixing wedges and fixing bolts<\/li>\r\n \t<li>Upper and lower cheek plates<\/li>\r\n \t<li>Spider caps and feed liners<\/li>\r\n<\/ul>\r\nThe type of rocks or raw material to be crushed will determine the type of grade we will offer. Generally, for primary crushers, we mainly offer 2 types of grades :\r\n\r\n<u>12-14% of Manganese <\/u>\u00a0: Non-abrasive area \u2013 Soft aggregates (LOS \u2265 25 \u2264 40)\r\n\r\n<u> 18-20% of Manganese<\/u>\u00a0: Abrasive area \u2013 Hard aggregates (LOS \u2265 15 \u2264 25).\r\n\r\n<u>LOS ANGELES<\/u> test will allow to measure the choc and wear resistance of the aggregates. If the measured LOS in an area is &lt; to 40, the aggregates are not very resistant to chocs. On the contrary, a measured LOS \u2265 to 15, the aggregates are very resistant to the chocs.\r\n\r\n<i>*NB : Due to the thickness of the primary jaws, the 21% manganese is not recommended if the abrasiveness of the aggregates is important.<\/i>","link":"https:\/\/minerals.smdo-industrie.com\/en\/product-category\/manganese-wear-parts-for-crushers\/jaw-and-gyratory-crushers\/","name":"Gyratory and jaw crushers","slug":"jaw-and-gyratory-crushers","taxonomy":"product_cat","parent":129,"meta":[],"menu_order":0,"acf":[],"_links":{"self":[{"href":"https:\/\/minerals.smdo-industrie.com\/en\/wp-json\/wp\/v2\/product_cat\/131","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/minerals.smdo-industrie.com\/en\/wp-json\/wp\/v2\/product_cat"}],"about":[{"href":"https:\/\/minerals.smdo-industrie.com\/en\/wp-json\/wp\/v2\/taxonomies\/product_cat"}],"up":[{"embeddable":true,"href":"https:\/\/minerals.smdo-industrie.com\/en\/wp-json\/wp\/v2\/product_cat\/129"}],"wp:post_type":[{"href":"https:\/\/minerals.smdo-industrie.com\/en\/wp-json\/wp\/v2\/product?product_cat=131"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
