What kind of machine is used to break large stones to about 15 cm? 5

Generally speaking, there are three kinds of crushers for crushing stones: jaw crusher, hammer crusher, cone crusher, and two kinds of crushers are generally used to crush large stones, that is, jaw crusher and hammer crusher, and the combination of these two crushers can crush large stones to the required size. Hammer breaking is also called counterattack breaking here, and the function is to crush the stone from the jaw break (also called a break) for a second time to achieve the required stone size.

Jaw crusher can choose the appropriate feed port size according to the size of the big stone, to crush for the first time, because the size of the big stone is different, the required production efficiency is also different, so the specific type of jaw broken according to their actual needs, impact breaking, can handle a variety of coarse, medium and fine materials (granite, limestone, concrete, etc.) with a side length of no more than 500mm and a compressive strength of no more than 250MPa. Its unique structure adopts keyless connection, high-chromium sheet hammer, and unique impact lining; Simplify the crushing process, high efficiency and energy saving; The finished product is in the form of a cube; The size of the discharge particle size can be adjusted.

Large stones can be crushed to about 15cm, and a jaw crusher can be used. Or with a box crusher.

Heavy hammer crusher or box crusher with large inlet, and the discharge can be adjusted no more than 15. The yield is high and practical, and the key is that it is not expensive.

How is a stone crusher made to break large stones into small, equal pieces?

Clause. First, the crusher manufacturing starts from the cover, the CNC plasma spray gun cuts the iron sheet in the water, and the water can prevent the smoke from being generated when the spray gun is cutting accurately. The steel plate moves back and forth between the two rollers, bends the steel plate to form the main body of the stone crusher, bends a little bit every time the steel plate is rotated, and finally when the two sides are closed, the steel plate forms a cylindrical shape, and is still on the roller, in fact, it is positioned and welded at both ends to maintain the shape, and then welded together completely.

Now it is ready to install the main body of the stone crusher, put it on the base with a crane and weld it with the placing motor and bearings, paint the exterior of the main body and install small accessories.

Clause. Second, the next is the internal assembly, the worker uses bolts to install the steel casting on the inner wall, when the big stone is hit everywhere in the crushing process, the strong steel casting can prevent the machine from being damaged, and the worker fixes the steel casting through the outside bolts. Now start assembling the bearings and shafts of the crusher, start with the bearings, carefully align them and start heating, the bearings will continue to expand after being heated, and when the diameter of the bearings becomes large enough, they will be put down into the shafts, and the bearings will shrink after cooling.

The spindles are tightly knit and this process takes several hours. Below, the workers heat up the opening of the bearing, let it expand, put the merged spindle and the bearing into it, and the bearing does cooling and shrinking, and fits it tightly.

Clause. 3. The other end of the spindle is also installed with a bearing and a bearing belt. Then there is the commissioning, where each housing must run for two hours so that the test machine can fully evaluate the indicators.

After passing the test, the bearing will be installed in the stone crusher, the installer drives six bolts to fix the bearing as a component, places the heated parts on the convex bearing, fixes it after cooling, and then uses two lock nuts to further fix the mechanical arm, weld the wheel on the steel plate, this is the impeller in the stone crusher, the similar turntable will be rotated to crush the large stone iron needle, the worker installs metal protection parts on the wheel, and the impeller is placed in the stone crusher and fixed in the center. Then the falling iron castings are installed, these are iron needles, which are placed in a circular shape and are used to crush large stones. Workers place the needle at an angle and fix it.

The crane puts the iron needle into the stone crusher, assembles it around the impeller and puts a lid on the stone crusher, and the worker puts the mark with brand information on the outside of the stone crusher. Once the motor is installed, the crusher is ready to start crushing the stones.

This stone crusher has a wide variety of pinions, made of the strongest stainless steel material, with strong screws that hold the plates together.

First of all, the drawings will be planned, then the drawings will be customized to other factories according to the drawings, and finally shipped back for assembly.

The factory procures parts from foundries and parts factories around the country and transports them to the assembly line to assemble them into crushers.
