The disadvantage of the gyratory crusher is no reliable insurance device and convenient discharging mouth adjusting device. At present, the domestic commonly used hydraulic gyratory crusher. This series cone crusher is the production of 1400/170 of the hydraulic gyratory crusher in our country. The structure of the crusher and ordinary gyratory crusher basic same, the difference is its adjustment and insurance device is controlled by hydraulic cylinder.The hydraulic cylinder is installed at the bottom of the frame, the broken cone bearing in the upper part of the hydraulic cylinder. The upper part of the hydraulic cylinder has three friction plates. The lower friction plate fixed on the spindle;The friction plate fixed to the column fortress;In the friction disk surface is spherical, the surface is flat. However, are you familiar with the lubrication system of cone crushers?

As insurance device of crusher, hydraulic equipment is safe, reliable and convenient quickly.When crushing cavity into the broken item, due to the crushing force, broken cone downward pressure plunger, namely make the oil pressure inside the hydraulic cylinder suddenly increases, when the oil pressure exceeds the gas pressure in the accumulator, hydraulic cylinder oil was crowded people in the accumulator. Thus broken cone with the plunger to drop, increase discharging mouth, until the broken out.Not broken after discharge, under the action of accumulator, oil by one-way throttle valve slow ground pressure in the hydraulic cylinder, which makes automatic reset broken cone smoothly. When a gouge size is too big and not through the discharging mouth, the hydraulic system will continue to rise, to the electric contact pressure gauge setting value, the control system can automatically to stop the main motor, to ensure the safety of the equipment.

The lubrication system of cone crushers is as follows: Gyratory crusher in thin oil and dry oil for lubrication.What they need and supply of lubricating oil by special hydraulic pump station. Oil along the pipeline from base oil hole on the cover under into the bottom space of eccentric shaft sleeve, and thus along the clearance between shaft and eccentric shaft sleeve, and the gap between eccentric shaft sleeve and the sleeve up.After lubrication the friction surface, a rise in oil to the eccentric shaft sleeve thrust disc.Another oil rising oil baffle ring meet on the way and flow to bevel gears.Lubricating oil components, the oil drain out. Crusher shaft bearing has a single feed and discharge tubing.Spindle suspension is by manual dry oil lubricating device note dry lubrication on a regular basis.

Rotary kiln is a combustion equipment, can use the solid, liquid and gas fuel, the cement plant is given priority to with the use of solid fuel in our country, because of the need to spray combustion, so the solid fuel made into powder.Pulverized coal pulverized coal into coal after drying, after warehouse, with the blower from the kiln head injection into the stove.Combustion air is made up of two parts, part in advance and conveying pulverized coal mixing and the function of the air, called 'air', generally accounts for 15% of the total air - 15%, most of the air through the cooling machine clinker cooling, at the same time itself be preheated to a certain temperature, into the furnace, this part is called 'secondary air'. However, do you know the belting Leather of rotary kiln?

The based information on belting leather of rotary kiln is as follows:

Belting leather is a solid circle rims, installed on the cylinder, the full weight of the rotary kiln, passed to roller belting leather.Belting leather with the cylinder on the wheel rolling, its itself also increase cylinder rigid role. Belting leather is in cast iron or steel, forging belting leather its cross section is solid structure, good quality service life long, but the heat dissipation is poor, poor rigidity, manufacture process is complex, cross section size larger belting leather, generally using the casting, the cross section has a solid rectangle and hollow box type two kinds

Belting leather on the cylinder of rotary kiln (http://www.sell-crusher.com/pro/p29.html) installation method has two kinds, the general is fixed, the belting leather rivet directly by plate on the cylinder.This kind of installation method limits the free expansion of cylinder, the thermal stress of shell and belting leather is bigger, so rarely used, the other is a loop on the cylinder, riveting or welding plate on the cylinder, belting leather and leave appropriate gap between plate, general for 3-6 mm, it is controllable heating stress and can make full use of the rigidity of belting leather, to reinforce the effect to the cylinder, therefore, is more commonly used methods.

With the continuous increase of the rotary kiln size, to perfect rigid demand is higher and higher, because of the mechanical manufacturing technology constantly improve current foreign some use belting leather with integration of cylinder structure, its structure characteristics, belting leather as support both parts, but also a part of the cylinder.The fixed shell and at the same time with the method of welding connection, instead of a suit, in order to improve the cylinder's rigidity.
