1 adjustable fine crusher the adjustable fine crusher mainly consists of a rotary part, guard plate, crushing chamber.The latest fine crusher equipped with a hydraulic device can be very convenient to maintain, save time cost.2 jaw crushing type jaw crusher, is the first choice for primary crushing equipment, with large crushing ratio, uniform product size, simple structure, the relatively small volume can be installed in the tiny space, etc.Therefore, it is widely used in mines, metallurgy, construction material, water conservancy and chemical industries.Compared with cone crusher, jaw type crusher has less investment, less finished flake and lower production cost.Compared with hammer crusher, the wear resistant parts have longer service time, high production efficiency and fewer maintain fees.The common jaw crusher has single toggle type and double toggle type, the former one also called as simple swing crusher, the latter one is called as complex swing crusher.3.Gyratory crusher the gyratory crusher is a large scale crushing machine which uses the gyratory movement of the crushing cone in the crushing cavity to extrude, squeeze and bend the materials.When the shaft sleeve rotates, the crushing cone is moving in eccentric around the center line of the machine continuously.The productivity of gyratory crusher is higher than that of jaw crusher.There are two types of discharging material and overload insurance, one is mechanical type, by adjusting the nuts on the top of the main shaft to lift up or down the crushing cone, thus change the discharge outlet width, and by cutting the safety pin on the driving pulley to stop overload.Another way is hydraulic gyratory crusher type, by changing the plunger under the hydraulic oil volume can adjust the crushing cone position, thus changing the size of the discharge port.4 cone crusher cone crusher widely used in the metal and mon-metal mines, cement, sand & gravel, aggregate, quarry, metallurgy and other industries.It is suited for fine crushing all kinds of ores and rocks with hardness 5 ~ 16, such as iron ore, non-ferrous metal ore, granite, limestone, quartzite, sandstone, cobblestone, etc.The working principle of cone crusher is the same as that of gyratory crusher, but it is only suitable for medium-sized crushing or fine crushing.The requirements of uniformity of particle size distribution in medium and fine crushing operations are generally higher than that in the coarse crushing operation.Therefore, a section of the parallel zone should be set at the lower part of the crushing cavity.In addition, the rotating speed of the crushing cone should be accelerated so that the material can be squeezed more than once in the parallel zone.The crushing of fine crushing operation is larger than that of coarse crushing operation, so the loose volume after crushing increases greatly.In order to prevent the crushing chamber from blocking, the total discharging cross section must be increased by increasing the diameter of the lower part of the crushing cone without increasing the discharging opening to ensure the required discharging granularity.When the simon spring safety cone crusher overloads, the cone-shaped shell forces the spring to compress and raise itself in order to enlarge the discharge port and discharge the non-broken material.The adjustment of the discharge opening is carried out by the adjusting cover, and the adjusting cover fixed with the shell can be rotated to drive the shell up or down by the thread on the outer circle, so as to change the size of the discharge opening.The safety and adjustment mode of hydraulic cone crusher is the same as that of hydraulic gyratory crusher.Maintenance of cone crusher 1, ensure full load production, avoid too coarse product granularity.2, optimize the cone crusher productivity by setting reasonable crushing ratio.3, it is necessary that equipped with an iron removal device.4, the spring cannot be too heavy pressured, the large pressure may occur shaft broke, light pressure may cause spring vibrating, influence the crushing efficiency.
Fixed jaw crusher: noise reduction noise is also a factor affecting energy conservation and environmental protection.According to the environmental protection survey report of 2015, noise not only threatens the living environment of human beings all the time but also harmsthe physical and mental health of human beings.Therefore, the radical treatment of noise is urgent to be solved.The emergence of noise cancellation circuitinstalled on the fixed jaw crusherimmediately attracts more attention from miners,because it not only fundamentally solves thenoise problem, but also improvesthe reliabilityonenergy conservation and environmental protection.the noise cancellation circuit is very flexible and it can be set on different parts of a jaw crusher according to the noise degree.
Single and double toggle jaw crushers are constructed of heavy duty fabricated plate frames with reinforcing ribs throughout.Manganese steel is used for both fixed and movable jaw faces.Heavy flywheels allow crushing peaks on tough materials.Double toggle jaw crushers may feature hydraulic toggle adjusting mechanisms.
(5) in the mineral processing reagents, truth-value development of all kinds of ores adaptable, high efficiency, low temperature resistance, non-toxic potions; the study also preparation, and adding the blends with elixir;mobile jaw crusher at present should focus on developed can not quartz silicate flotation of gangue minerals, high efficiency of collector, expand the application range of the reverse flotation technology.
As is known to all the heavy machinery crusher manufacturers, we all learn that mobile jaw crushers price is different according to a different specification, in turn, thediversemining industrieshave various needs and different productivity requirements.Science, mobile jaw crushers are widely used in the mining machinery market now.Therefore, china hongxing would arrange the tailor-made mobile jaw crusher plant for customers.
