    Product brief introduction: wet ball mill in China's processing industry in an extremely broad scope of application, the wet ball mill and ball mill, high energy consumption, accounting for more than 50%, thus exploring the characteristics and control strategies of ball mill is very important. And the wet ball mill internal working mechanism is very complex.

    Wet ball mill product introduction:

    ( includes 1 wet ball mill; basic characteristics of 2 wet ball mill applied to industry; 3 the equipment applications )

    Wet ball mill is mainly used for wet plant finished product and raw material grinding, also applies to the metallurgical, chemical, electric power and other industrial and mining enterprises grinding all kinds of ores and other abrasive material. Can be used to open the flow grinding, also applies with the powder selecting machine consisting of a circular ring flow grinding. Wet grinding of strong material adaptability, continuous production, broken than large, easy to control the grinding fineness of product features. Wet ball mill can dry production can also be wet production. Can also be grinding and drying at the same time.

    Ball mill is the key equipment of grinding material, using dry and wet ball mill grinding all kinds of ores and other materials. According to the different ways of ball mill discharge can be divided into two types: the grid and the overflow type.

    The performance characteristics of wet ball mill:

    ( 1) the transmission adopts the rolling bearing instead of sliding bearing, thereby greatly reducing the friction force, easy start, notable energy saving.

    ( 2) discharge end of the cone design, both to increase the volume, forcing cone end materials and steel grade, more close to the outlet, ball diameter and smaller, increases the repeated grinding effect;

    ( 3) the use of trench lining board of ball ring, increases the contact surface, mine, strengthen the role of ore grinding, and the ability to ascend, the energy consumption is reduced

    (4 ) using the whole frame, convenient construction ( construction of a cement foundation. ) and equipment installation.

    Wet ball mill and dry compared advantages:

    Wet ball mill system and dry ball mill, from mining to lime stones into the grinding process is the same, according to foreign experts: from the ground to the slurry made of wet grinding, significant investment to save more. Despite the wet grinding dry mill of high power consumption, but the whole system or a small power consumption, low running cost. Wet grinding operation cost is only 1 / 3 of dry grinding system. The scheme of wet grinding process is simple and reliable, and can avoid the dry grinding system in the pulverized coal lift and noise on the influence.

    Wet ball mill process flow diagram:

    By weighing belt feeder conveyor to lime with Shi Hui by the filtrate pumped to filtrate water ( or water ) and limestone cyclone underflow coarse slurry together by ball mill 's entrance into the ball mill cylinder body, the cylinder of ball mill limestone by ball impact, pressing and milling and the filtrate water ( or water ) to form a slurry. Then enters the discharge slurry tank, a slurry pump into the cyclone hydrocyclone separation of slurry thickness, large particles is screwed onto the hydrocyclone underflow slurry at the bottom of the form, returns to the ball mill grinding entrance was once again, and the slurry in the small particles from the top spin out overflow into the limestone slurry tank standby. Then through the limestone slurry pump to the absorption column.

    According to the design requirements, to ensure the system material balance, concentration of slurry and fineness of products qualified, in discharge slurry tank is provided with a liquid level measurement, cyclone station with online pressure measurement instrument. Slurry pipeline is provided with a slurry density measurement online, such as electric valve. Mill entrance and discharge slurry tank water system with on-line flow measurement, automatic adjusting valve. The system is also provided with a flushing water device used to stop or when switching flushing pump, pipeline and cyclone.

    Wet ball mill structure:

    ( 1) 1 belt driving device of wet ball mill, ( including the tube body, end cover, a feeding opening, a material outlet, liner, bearing, gear lubrication system, installation lubricants, couplings, gear motor, initial ball )

    ( 2) 1 sets of machine tools

    ( 3) 1 sets of equipment debugging of lubricating oil

    ( 4) 1 limestone slurry hydrocyclone station

    ( 5) 1 Taiwan products distribution box

    ( 6) 1 sets of wet ball mill discharging slurry tank

    ( 7) 1 sets of wet ball mill discharging slurry agitator ( belt driving device )

    ( 8) 2 belt driving device of wet ball mill discharging slurry tank pump ( one with a preparation )

    ( 9 ) 1 sets of process instrumentation

    ( 10 ) 1 sets of valve technology

    ( 11) 1 sets of equipment inside pipeline

    ( 12) 1 sets of the stochastic spare parts

    All ancillary equipment plate, anchor bolts, nuts and washers

    The working principle of wet ball mill:

    Wet ball mill working principle is a motor through a speed reduction device to drive the rotating cylinder, cylinder cents broken ore and steel ball in the rotating cylinder by the friction force and centrifugal force was liner to a certain height through the action of gravity, is falling and cascading, ore in shock and grinding effect gradually be smash. Crushed ore discharging portion of the discharge cylinder. Discharge of minerals in the spiral classifier in the grading of qualified products, coarse sand through the United feeder back to grinding in ball mill. Feeder for continuous feeding evenly, ore combined feeder continuous evenly into the mill, is the ground material from the mill everfount discharge. The ball mill is a day 24 hours of continuous work grinding equipment.
