Five star heavy industry: instruction for cone crusher

1、 The purpose of the machine

Cone crusher is widely used in metallurgical industry, construction industry, chemical industry and silicate industry. It is suitable for crushing various ores and rocks with medium and above hardness.

2、 Structure and composition of the machine

1. When the cone crusher is working, the motor drives the eccentric shaft sleeve to rotate through the elastic coupling device, transmission shaft and a pair of bevel gears. The broken cone axis line rotates under the forced action of the eccentric shaft sleeve, so that the crushing wall and the rolling mortar wall are sometimes close and sometimes far away, and the ore is continuously squeezed and impacted in the crushing chamber and is broken.

2. The machine is composed of frame, transmission shaft, eccentric sleeve, bowl bearing, broken cone, supporting sleeve, adjusting sleeve, feeding, spring, elastic coupling device, lubrication and electrical appliances.

3、 Installation of the machine

1. In the workshop where the cone crusher is installed, there should be lifting equipment so that it can be used during the installation and maintenance of the machine. The lifting capacity is shown in the table below

2. There should be enough space under the foundation to install transportation equipment.

3. In order to prevent the foundation from being damaged, the upper part of the foundation must be covered with a guard board, which shall be provided by the user.

4. The user can change the position of lubrication system and electrical operation according to the situation, but the sequence shall not be changed.

5. Installation of rack

(1) When installing the frame, adjust the levelness and perpendicularity with 8-12 groups of base plates and wedge iron supports near the anchor bolts. The levelness is based on the annular machining surface of the frame, and the deviation is not more than 0.1 mm / M measured with a level instrument. The perpendicularity is measured with the suspension hammer method with the bushing center of the frame as the benchmark.

(2) After the frame is adjusted and tightened, the base plates shall be assembled and welded together to avoid movement.

(3) After the equipment is fully installed, the second pouring shall be carried out.

(4) Keeping the levelness of the frame can ensure the reliable operation of the machine. Otherwise, it is easy to cause local wear of the bushing and affect the abnormal dust setting of the spindle and water seal.

6. Installation of transmission shaft

(1) When installing the transmission shaft, the gasket should be padded between the frame and the flange of the transmission shaft frame. Axial displacement 0.4-0.8 mm

(2) The center deviation between motor shaft and transmission shaft shall not be less than 0.15mm

7. Installation of eccentric sleeve

(1) Before installing the eccentric sleeve, the gasket shall be assembled on the bottom support cover, and the bottom tray shall be installed at the lower end of the frame with the hook (installation tool). Then, the round plate, the middle disc and the lower disc shall be installed on the bottom tray successively with the hook, and the bulge of the lower disc and the concave part of the bottom support cover shall be clamped.

(2) Match the eccentric sleeve, and then put the eccentric sleeve into the center hole of the frame. When installing, the bevel gear should be stable, and the bevel gear should not be impacted. The lifting lug of bevel gear shall be used during hoisting.

(3) After the eccentric sleeve is completed, the outer end faces of the big and small bevel gears must be aligned, and the tooth clearance of bevel gears shall be checked. Bevel gear tooth side clearance a = 2.6-3.2mm, tooth tip clearance B = 4mm

8. Installation of bowl bearing

(1) The bowl bearing frame shall fit closely with the machine, and the tightness of the horizontal contact surface shall be checked with a feeler gauge.

(2) When installing the bowl bearing, attention should be paid to protecting the water inlet pipe, drainage pipe, protective ring and dust ring, so as to avoid damage during installation.

9. Installation of crushing cone

(1) Remove the protective oil layer on the spindle and body spherical surface, and blow the lubricating oil hole and oil groove with wind.

(2) Apply a layer of grease on the cone of the spindle and a layer of mechanical oil on the spherical surface of the body.

(3) When the cone is broken, it should be put into the eccentric sleeve gently to make the spherical surface contact with the bowl shaped bearing bush, and pay attention to avoid damaging the ring ring ring and the protection ring.

10. Installation of support sleeve

Before installing the support sleeve, remove the dirt in the serrated thread, and check whether there is any damage on the thread. If any, correct it immediately.

11. Spring installation

Adjust the working height of spring H = 372mm

12. Installation of water seal dust-proof device

(1) When installing water pipes, it is necessary to avoid being hit and worn by ore.

(2) The inlet and outlet pipes should be installed tightly and easy to remove.

(3) There should be a valve to adjust the water quantity on the water inlet pipe.

(4) When the machine stops working, the water inlet pipe should be equipped with a device that can discharge all the water in the water tank.

(5) A bell mouth connecting pipe for easy inspection shall be set at the place where the drain pipe is close to the water storage tank.

13. Installation of lubricating device

Before installing the broken cone, the installation of the lubricating device should be completed to facilitate the test of the lubricating device. If the lubrication fails, it is convenient to disassemble and repair.

Installation adjustment set

(1) Before installation, the dirt in the serrated thread must be removed. Repair the damaged parts during transportation, and check the soundness of mortar wall and zinc alloy.

(2) The pulley can be used when installing the adjusting ring into the serrated thread of the supporting sleeve.

(3) The user can adjust the clearance of ore discharge outlet as required, but the gap size must be within the specified range, and then tighten the tension bolt connecting the adjusting ring.

15. Installation of feeding device

In order to make the ore enter the crushing space evenly, the feeding device must be installed correctly. The feeding device is provided by the user.
