Jaw crusher is a main type of rock crusher used to crush minerals or stones into smaller sizes. It is an essential machine in a wide range of fields such as mining, quarrying and construction industries. Jaw crushers are usually used together with cone crushers, impact crushers and sand making machines to form a sandstone production line. Jaw crusher is used to crush various mineral rocks with compressive strength not exceeding 320MPa, such as cobblestone, calcite,granite, aggregate,quartz, concrete, dolomite, blue stone, iron ore, limestone, construction waste, etc.Details+

Jan 01, 2012 · In Grate-Kiln process, green pellets are fed on oil or gas-fired endless Straight Grate machine where they are dried and preheated. The preheated pellets are then fed to a rotary kiln where their temperature is raised in oxidizing atmosphere to 1290–1400 °C. In induration, ore grains are sintered together with oxidation and slag-forming bondsMore Details
For both processes the plants consist of many pieces of equipment. The major areas or processes in the plant are mixing, balling, indurating and product handling. Mixing is where the properly ground ore is combined with binding agents like Bentonite or organic binders, fluxing agents like limestone or dolomite, and if the ore is a Hematite withMore Details
Pelletizing disc is the most commonly used balling equipment in iron ore pelletizing plants. Materials on pelletizing disc are mixed with an appropriate amount of water to be processed into green pellets. Once pellets have reached the desired size, they leave the pelletizing disc and proceed to the next stepMore Details
The grate is used to dry, preheat, oxidize and solidify the green pellets by using the residual heat of the ring cooler and the hot air discharged from the rotary kiln on the grate plate with the ball cloth containing iron. Then it is directly sent to the rotary kiln for roastingMore Details
Apr 15, 2020 · 1. Introduction. Green iron ore pellets are nearly spherical agglomerates produced in balling discs or drums from a mixture of fine iron ore concentrate, agglomerating agents and water .These pellets are then indurated, typically in horizontal travelling grate furnaces, reaching their hardened state which allows handling without significant mechanical degradation from the pelletizing …More Details

Plastic pellet making machine is widely used in granulation of PET sheet, HDPE, LDPE, PP, and other plastic films after washing. Plastic pellet making machine has a very promising future, not only for it can improve the environment, but also bring large profits to us in the market. If playback doesn't begin shortly, try restarting your deviceMore Details
A process for producing fired pellets by granulating finely-ground iron ore and subjecting the resulting granules sequentially to drying, dehydration, preheating, and firing, wherein said process comprises adding an additive to said finely-ground iron ore at the time of granulation, said additive reacting with iron ore to form a compound which has a melting point lower than the preheatingMore Details
At the time of preheating treatment of a green pellet, the liquid-phase sintering of the iron ore powder, is executed. The additive is reacted with the iron ore to produce the low m.p. compound, and this low m.p. compound develops a liquid-phase sintering at the contacting points among the iron ore particles and the iron ore particles are joinedMore Details
There are three kinds of roasting equipment for pellet: shaft furnace, belt type roasting machine and grate - rotary kiln.Roasting with shaft furnace, small capacity, uneven heating, poor adaptability to raw materials;But the equipment is simple and easy to operate.China has made a breakthrough in the roasting technology of shaft furnace.The belt type roasting machine is mainly dravo-lurgi, which has the …More Details
Energy efficiency The Grate-Kiln® induration machine is composed of three separate process pieces of equipment. The traveling grate is used primarily to dry and preheat green balls for feeding into the rotary kiln, where they are indurated. Once the green balls are made they are spread out evenly across the grateMore Details
Operation. Outotec's traveling grate pelletizing process consists of a green balling section where, after the mixing stage, green pellets are formed either by rolling on discs or in drums. The green pellets are then screened and heat-hardened in the indurating furnace. The process comprises four steps:More Details
Feb 23, 2013 · Disc pelletizer is preferred for the production of the quality green pellets since in the disc pelletizer it is easy to control the operation with minimum of foot space. The disc pelletizer is an inclined pan having around 5 metres (m) to 7.5 m diameter. It rotates at around 6 …More Details
Mar 08, 2021 · Types of skillets. Preheating an empty skillet is most straightforward when it comes to cast iron or other uncoated metal, such as stainless steel. What about nonstick? Depends who you askMore Details
Jun 08, 2019 · High-LOI iron ore fines are required for detailed laboratory pelletization studies and are used in pellet making. The received iron ore is martite–goethitic and hematite–goethitic form of ore with high LOI content. The iron ore consists of 57.7% Fe, 6.19% SiO2, 2.69% Al2O3, 8.80% moisture and 8.85% LOI. From thermo-gravimetric analysis, theMore Details
Mar 21, 2015 · In this process, balling equipment produces green balls from the pre-wetted material prepared in the previous process. The balling drum and the disc pelletizer are the most widely used devices for forming green balls. Both of the units utilize centrifugal force to …More Details
