SBM is a manufacturer of crusher plant in China, and supplies all kinds of crushers and grinding mills such as jaw crusher, impact crusher, cone crusher, vsi crusher, raymond mill, ball mill, vertical mill for sale. They have a feature of advanced structure, reliable operation, high quality and easy in use.

Combining these machines, SNM can supply various complete plants to satisfy different quarry operation. It is also capable to provide the quarry design, facilities installation and regulation as a coordinated service process. There are two types of complete sets: stationary, and mobile with productive capacity from 50t/h-500t/h..

Crushing Plant Process:

Big materials are fed to the jaw crusher evenly and gradually by vibrating feeder through a hopper for primary crushing. After first crush, the material will transferred to impact crusher by belt conveyor for secondary crush; the crushed materials will then transferred to vibrating screen for separating. After separating, the parts that can meet standard will be transferred away as final products, while the other parts will be returned to impact crusher, thus forming a closed circuit. Size of final products can be combined and graded according to customer’s specific requirement. We can also equip dust catcher system to protect environment.

The design of a stone crushing production line is usually decided by several factors:

1) raw materials to be crushed

2) The hardness, percentage of Si, moisture percentage of the raw materials

3) The average size of the raw materials before entering into the crushing system

4）Requested product sizes, percentage of the sizes, and their usage

5) hour capacity of the crushing line

Aoocrding to the different raw materials, we can design different crushing production line, such as # Granite crushing plant

# Limestone crushing plant

# Basalt crushing plant

# River stone crushing plant

Ball mill operation and maintenance:

Ball mill is a used widely grinding mill in mining industry, it's operation and maintenance is essential for miner.

To make the ball mill operate good, we must strictly abide by the operation and maintenance procedures.

Before starting the ball mill, check whether the connecting bolt, gears, couplings are tightening;

Check whether the oil of the oil tank and the reducer is in the adequacy, and Whether the lubricating device and instrumentation have problems. Determines the flow of pipeline. Check whether there are ore to prevent the ball mill machine running. Check the ring gear and pinion gear case with or without abnormal noise.

The order start machine is:First start the ball mill oil pump. When the oil pressure reach 1.5 ~ 2.0 kg / cm2, it is allowed to start the ball mill, and then start the grading machine. All are functioning properly, then start grinding.

In operation, we must always pay attention to bearing temperature. The temperature shall not exceed 50 ~ 65℃. We also always pay attention to motors, voltage, current, temperature, sound, etc. And pay attention to lubrication system. The temperature of the oil tank shall not exceed 35 ~ 40 ℃, the pressure to the pipeline should be maintained at 1.5 ~ 2.0 kg / cm2. Check the lubrication of transmission components such as  gear, main bearing, grading machine reducer. Constantly pay attention to the change of nature of ore, and to take appropriate measures in a timely manner under the circumstances.

When stopping ball mill, First stop the feeder machine, then stop the ball mill machine until the ore has been dealt with. The last is pump. With grading machine screw lifting equipment to raise sand surface, and then stop grading machine.

the main components of jaw crusher

1.         Rack

The rack is the opening framefor supporting the eccentric shaft and bear fragmentation reaction of materials, require sufficient strength and stiffness, which is often cast as a whole cast, minimal machine can also be used iron steel instead of high-quality cast. Sub-frame cast mainframe. and then bolt firmly linked into the overall, it is a complex casting process.

2.         jaw plate and check plate

Both fixed jaw plate and movable jaw plate are consist of jaw plate and jaw bed. They should have sufficient strength and rigidity to withstand fragmentation reactions, which are mostly cast steel or cast iron.

3.         Jaw Crusher transmission parts

Eccentric shaft is crusher machine spindle, bent by the enormous torque, cast high carbon steel. Eccentric part required fine finishing, heat treatment. one end of eccentric shaft is mounted pulley, the other end with the flywheel installed.

4.         conditioning

Conditioning installations have wedge, plate type and the hydraulic type, and other kinds, generally is wedge. wedge is formed by the two, the former wedge can move easily withstand push back plate; wedge after the wedge for the adjustment can be up and down Mobile, the screw force it to move up or down to adjust the size of the discharge port.

5.         Flywheel

The flywheel is cast iron or cast steel. the minicomputer often has integral flywheel.  When flywheel manufacture, installation, pay attention to static balance.

6.         Jaw Crusher Lubrication Device

Eccentric shaft bearing lubrication cycle is usually concentrated. Spindle and thrust plate bearing surface generally use the grease gun oil to the oil by hand. the swing angle of fixed jaw plate is small, so that lubrication between the spindle and bearing is difficulty. open a number of oil groove, open a ring at middle part to connecte the oil groove. and then forced into the dry butter oil pump lubrication.
