The mini stone crusher from SBM refers to the roller jaw crusher to process coal gangue. The roller jaw rock crusher melds the concepts of jaw crushing and roll crushing long employed in the mining and rock-crushing industries. A single roller jaw rock crusher would be less complex and would weigh about half as much as does an equivalent conventional combination of a jaw crusher and a roller crusher. In the mining and rock-crushing industries, it is widely recognized that in order to reduce the particle size of minerals, it is often necessary to employ a succession of comminution machines. Jaw crushers are generally used for coarse crushing, cone crushers for intermediate crushing, and roll crushers for producing finer particles.
A mini stone coal gangue roller jaw crusher would include a single actuator and processing wedge gap to perform the functions of a jaw crusher and a roll crusher. The wedge gap would be formed between an actuated jaw-plate and floating jaw plate equipment with a roller at its lower motor- and gearbox drive that would turn a cam to produce an eccentric motion of the actuated-jaw-crusher.

How many types of ball mill 1. Based on the axial orientation a. Horizontal ball mill. It is the most common type supplied from ball mill manufacturers in China. Although the capacity, specification, and structure may vary from every supplier, they are basically shaped like a cylinder with a drum inside its chamber. As the name implies, it comes in a longer and thinner shape form that vertical ball mills. Most horizontal ball mills have timers that shut down automatically when the material is fully processed. b. Vertical ball mills are not very commonly used in industries owing to its capacity limitation and specific structure. Vertical roller mill comes in the form of an erect cylinder rather than a horizontal type like a detachable drum, that is the vertical grinding mill only produced base on custom requirements by vertical ball mill manufacturers. 2. Base on the loading capacity Ball mill manufacturers in China design different ball mill sizes to meet the customers from various sectors of the public administration, such as colleges and universities, metallurgical institutes, and mines. a. Industrial ball mills. They are applied in the manufacturing factories, where they need them to grind a huge amount of material into specific particles, and alway interlink with other equipment like feeder, vibrating screen. Such as ball mill for mining, ceramic industry, cement grinding. b. Planetary Ball Mills, small ball mill. They are intended for usage in the testing laboratory, usually come in the form of vertical structure, has a small chamber and small loading capacity. Ball mill for sale In all the ore mining beneficiation and concentrating processes, including gravity separation, chemical, froth flotation, the working principle is to prepare fine size ores by crushing and grinding often with rock crushers, rod mill, and ball mils for the subsequent treatment. Over a period of many years development, the fine grinding fineness have been reduced many times, and the ball mill machine has become the widest used grinding machine in various applications due to solid structure, and low operation cost. The ball miller machine is a tumbling mill that uses steel milling balls as the grinding media, applied in either primary grinding or secondary grinding applications. The feed can be dry or wet, as for dry materials process, the shell dustproof to minimize the dust pollution. Gear drive mill barrel tumbles iron or steel balls with the ore at a speed. Usually, the balls filling rate about 40%, the mill balls size are initially 3080 cm diameter but gradually wore away as the ore was ground. In general, ball mill grinder can be fed either wet or dry, the ball mill machine is classed by electric power rather than diameter and capacity. JXSC ball mill manufacturer has industrial ball mill and small ball mill for sale, power range 18.5-800KW. During the production process, the ball grinding machine may be called cement mill, limestone ball mill, sand mill, coal mill, pebble mill, rotary ball mill, wet grinding mill, etc. JXSC ball mills are designed for high capacity long service, good quality match Metso ball mill. Grinding media Grinding balls for mining usually adopt wet grinding ball mills, mostly manganese, steel, lead balls. Ceramic balls for ball mill often seen in the laboratory. Types of ball mill: wet grinding ball mill, dry grinding ball mill, horizontal ball mill, vibration mill, large ball mill, coal mill, stone mill grinder, tumbling ball mill, etc. The ball mill barrel is filled with powder and milling media, the powder can reduce the balls falling impact, but if the power too much that may cause balls to stick to the container side. Along with the rotational force, the crushing action mill the power, so, it is essential to ensure that there is enough space for media to tumble effectively. How does ball mill work The material fed into the drum through the hopper, motor drive cylinder rotates, causing grinding balls rises and falls follow the drum rotation direction, the grinding media be lifted to a certain height and then fall back into the cylinder and onto the material to be ground. The rotation speed is a key point related to the ball mill efficiency, rotation speed too great or too small, neither bring good grinding result. Based on experience, the rotat
ion is usually set between 4-20/minute, if the speed too great, may create centrifuge force thus the grinding balls stay with the mill perimeter and dont fall. In summary, it depends on the mill diameter, the larger the diameter, the slower the rotation (the suitable rotation speed adjusted before delivery). What is critical speed of ball mill? The critical speed of the ball mill is the speed at which the centrifugal force is equal to the gravity on the inner surface of the mill so that no ball falls from its position onto the mill shell. Ball mill machines usually operates at 65-75% of critical speed. What is the ball mill price? There are many factors affects the ball mill cost, for quicker quotations, kindly let me know the following basic information. (1) Application, what is the grinding material? (2) required capacity, feeding and discharge size (3) dry or wet grinding (4) single machine or complete processing plant, etc.

Phosphorite is widely used in the fertilizer industry, aviation, food, medical, defense and other sectors. With the rising demand for phosphorite and rapid exploration of phosphorus-rich ore in recent years, phosphorus-rich ore becomes less and less. Therefore, how to explore phosphorus lean ore arise more attention, which also prompts the innovation and development of phosphorite ore dressing technology and equipment
Most phosphate ore has the lower hardness that is easy to crush. Therefore, Xinhai usually uses two stage a closed circuit or two opening crushing. Xinhai jaw crusher is used for coarse crushing, cone crusher is used for secondary crushing, and then round vibrating screen and linear vibrating screen are generally used for screening equipment.
Phosphorite has high grindability, so Xinhai often adopts a closed-circuit or two stage a closed-circuit grinding process. In general, conventional ball mill (grid type ball mill or overflow type ball mill) has great energy consumption, large steel consumption and high grinding cost. Then Xinhai especially improved each type of ball mill that makes steel consumption decrease by 20% ~ 30%. In addition, Xinhai especially adopts super wear-resistant rubber liner, which can effectively improve the service life of liner and improve operating rate of ball mill.
Common phosphorite beneficiation processes include scraping-desliming process, heavy medium separation process, flotation process, gravity separation + magnetic separation + flotation process, roasting-digestion process, microbiological treatment process, dry electrostatic separation and magnetic coating process. In general, Xinhai often adopts flotation process and heavy medium separation + flotation process in phosphorite beneficiation process.
Direct-reverse flotation and double reverse flotation process can beneficiate phosphate minerals by eliminating silicate minerals and carbonate minerals, which can handle refractory sedimentary type silicon calcium (magnesium) phosphate rock;
Main Flotation Equipment: Common floatation cells are self-induced mechanical agitation type, air-inflation mechanical agitation type, air-lift flotation cell. At present, Xinhai has developed various flotation equipment with full specifications (applied in the large, medium and small plant), high operation efficiency, low maintenance rate, low energy consumption and good flotation index, which greatly reduce the flotation costs.
Advantages: this process is widely used in the separation of silicon calcareous phosphate ore. Phosphorus concentrate grade reaches 30%~ 41% and phosphorus recovery rate is up to 75%~ 90%. Heavy medium separation has low cost and small environmental pollution. Heavy medium separation can discharge most tailings, which greatly reduce flotation agents and equipment and save ore dressing cost.
Heavy Medium Separation and Flotation Equipment: Xinhai usually adopts heavy medium cyclone and jig as heavy medium separation equipment and various flotation equipment. The common heavy medium includes silicon iron, magnetite, pyrite and so on. Xinhai has developed various diaphragm jig, sawtooth wave jig and flotation cell that can provide the most suitable equipment for all kinds of phosphate ore separation, and achieve the best separation indexes.
