1. The 1st step — Crushing. The Raw rock minerals will be fed into the crushers to get the discharge size less then 25mm. Usually it will need 2 crushers, the primary crusher is for cutting down the big size of rocks, and the second crushers is for getting the size of -25mm. 2. The 2nd step — Grinding. The grinding machine will be ball mill

Nov 18, 2008 Basic principle Ball mill is generally used to grind material 1/4 inch and finer, down to the particle size of 20 to 75 microns. To achieve a reasonable efficiency with ball mills, they must be operated in a closed system. There is a specific operating speed for most efficient grinding.

Grate ball mill (grate discharge ball mill) is a ball milling machine used to grind various ores and other materials. Grate type ball mill is a traditional ball milling equipment for forced ore discharge by ore discharge grate.. Its basic structure and grinding process are basically the same as the overflow type ball mill, but the structure of the ore discharge part is different.

Jun 29, 2021 The difference in structure. 1. Dry type. The ball mill is equipped with a cylindrical rotating device and two bins, which can rotate by gears. The discharge port is straight, and there are also air intake devices, dust exhaust pipes, and dust collectors. 2. Wet type. The structure of the ball mill

Mill orientation. For smaller plant, the mills can be arranged in parallel if the products feed the same discharge hopper. This is more difficult for larger mills as the diameter of the mills drives the height required to maintain the discharge launder slope. In this situation the mills

Feb 08, 2017 The operating principle of the ball mill consists of following steps. In a continuously operating ball mill, feed material fed through the central hole one of the caps into the drum and moves therealong, being exposed by grinding media. The material grinding occurs during impact falling grinding balls and abrasion the particles between the balls. Then, discharge of ground material performed

8.3.2.2 Ball mills. The ball mill is a tumbling mill that uses steel balls as the grinding media. The length of the cylindrical shell is usually 1–1.5 times the shell diameter ( Figure 8.11). The feed can be dry, with less than 3% moisture to minimize ball coating, or slurry containing 20–40% water by weight.

The ball mill discharge pumps (one operating, one spare) will pump the combined SAG mill cyclone overflow and the ball mill discharge to the secondary mill cyclones. Cyclone underflow flows to the ball mill feed. Dry lime will be fed from a silo adjoining the ball mill pump box directly into the pump box. Cyclone overflow will flow to a trash

ball mill discharge launder how does a grate discharge mill work . how a grate discharge ball mill works. how a grate discharge ball mill works. as a leading global manufacturer of crushing, grinding and mining equipments, we offer advanced, reasonable solutions for any size-reduction requirements including quarry, aggregate, and different

For overflow ball mills, the charge should not exceed 45% of the mill volume . For grate discharge mills, the charge should occupy about 50% of the mill volume . Bond developed a relationship that can be used to determine the percent charge by volume as a function of the vertical height above the charge, He, and the radius of the mill, R, i.e.,

SAG mill discharge, together with the ball mill discharge, is diluted with mill water in the cyclone feed sump and pumped to a cyclone cluster. Cyclone underflow flows by gravity to feed the ball mill. with screen underflow returned to the No 1 CIL tank discharge launder by gravity. Water sprays on the screen wash most of the adhering ore

A Ball Mill Discharge Pump Box (not shown on Figure 6-6) receives ball mill discharge product with a P80 of 0.00787 in (65mesh), cyclone bank from each mill is combined in a launder and then divided into two streams of approximately equal volume, which

Aug 19, 2021 Assembly drawing of Grate discharge ball mill. The structure of various specifications of ball mill is basically the same, the following is an example of 2700x3600mm grate ball mill produced by Henan Deya Machinery Co., Ltd. The following figure shows the assembly drawing of 2700x3600mm grate ball mill produced by Henan Deya Machinery Co., Ltd.

Aug 30, 2019 1 Calculation of ball mill capacity. The production capacity of the ball mill is determined by the amount of material required to be ground, and it must have a certain margin when designing and selecting. There are many factors affecting the production capacity of the ball mill, in addition to the nature of the material (grain size, hardness, density, temperature and humidity), the degree of

A wet ball mill 1 m 1 m was This is more difficult for larger mills as the diameter of the mills drives the height required to maintain the discharge launder slope. In this situation the mills are often located at right angles. Alternatively, a transfer hopper can be used. This decision is usually based on the difference in cost and

Discharge of pebbles, finer rock, ball scats and slurry from mills and its flow through trommels, and into other processing operations has strong impacts on overflow ball mill performance.

Optimization of the single stage SAG mill circuit at the . - zenith. implemented which allowed the SAG mill to operate similarly to a large ball mill .. the second CIC plant is used in the mill for process and CCD wash water as the . media size plus interaction with discharge grates and classification efficiency.

Trommels remain widely and often work with the screening of mill discharge streams. Tumbling mill (AG, SAG, rod, and ball mills) discharge streams usually pass through a trommel screen attached to the mill outlet to prevent grinding media scats from reaching subsequent processing equipment, and the case of AG/SAG mills, to extract pebbles to

Jun 23, 2020 Converting a ball mill from overflow to grate discharge involves installing a grate inside the mill at the discharge end. The grate holds the balls inside the mill but allows the slurry to pass through, and it is then pumped out of the mill by the pulp lifters. This is different to an overflow mill which holds the slurry and balls inside until
