PLFC Vertical Shaft Hammer Crusher

Working Principle:

After the material enters the body from the feeding port, it falls on the surface of the rotor. Because the rotor rotates with the spindle at high speed, the material rotates synchronously with the spindle through the raised spreading plate on the rotor and throws the material to the counterattack plate. Due to the special structure of the counterattack plate, the material is rebounded and has a downward and inward gathering movement, so as to enter the breakage. After being hit by the impact plate and the counterattack plate, the broken cavity moves in a circular motion in a “Z” shape around the rotor until it is broken to a certain particle size and the cavity is discharged from the discharge port.

Product Instructions for Use:

1. Installation: Check the size of the anchor bolt hole and correct it; hoist the mainframe and motor to the foundation respectively, adjust the vertical and pulley level, and fix the feed hopper; after the second grouting solidification, accurately adjust the pulley level and tighten the triangular belt; before installing the hopper, unscrew the bottom bolt of the bearing seat and install the “U” oil drain pipe; electricity The machine needs to be well grounded.
2. Test operation of the empty car: check the tightness of the bolt, add lubricating oil, manually move the pulley to confirm that there is no impact sound; start the power and irdle for 0.5-1 hours, and after the shutdown is fully checked for any abnormalities, the load operation can be carried out (mainly clockwise rotation, reverse is also possible).
3. Load operation: After 24 hours of load operation, start the machine and fasten all the bolts, and deal with abnormalities found in production in time.

Product Maintenance:

1. After the machine runs smoothly, add the material, feed evenly, do not overload, and pay attention to the current change.
2. The feed needs to meet the requirements. Remove large ores and metal blocks. It is recommended to install an iron remover.
3. When the discharge particle size is abnormal, stop the machine to check the wear of the impact plate, the counterattack plate and the elasticity of the belt, and adjust or replace it in time.
4. Avoid blockage of the discharge port, and prevent it from affecting the discharge and damaging the discharge pipe.
5. Add No. 3 composite calcium-based grease to each shift; if the bearing is overheated, it will be stopped immediately for troubleshooting.
6. Stop feeding before shutting down, drain the materials in the cavity and then shut down.
7. When the speed and sound are abnormal, stop the material immediately and turn it on after troubleshooting.
8. Regularly check and maintain, and replace consumable parts in time to ensure the normal operation of the equipment.

Application scenario:

PLFC vertical shaft hammer crusher is mainly used for medium and fine crushing of medium and low hardness materials, and is widely used in the fields of sand and stone aggregate production lines, building materials processing and resource reuse. This equipment is suitable for crushing and processing materials such as limestone, coal tar, shale and some construction waste, and can further crush medium-grained raw materials to a particle size suitable for screening or sandmaking.

(1) In the sand and stone production line, PLFC is usually used in the middle crushing or fine crushing link. It is located after the jaw crusher and is used to further refine the material and provide suitable feeding conditions for the screening or sandmaking process. In small and medium-sized sand and stone factories, this equipment is also often used as the main crushing equipment.

(2) In cement plants, building materials industry and construction waste resource treatment projects, PLFC vertical shaft hammer crusher is also widely used, especially suitable for production scenarios that are sensitive to investment costs but need to stabilise production capacity. It is one of the important equipments to realise recycled aggregate processing.

FAQ：

Q：Which scenario is the priority to choose PLFC vertical shaft hammer crusher?

A：It is suitable for production scenarios that require high fine sand yield, round grain shape, and low needle sheet shape: boutique mechanism sand processing, highway/water conservancy high-standard aggregates, solid waste recycled sand production, building materials raw materials fine crushing, slag clinger deep processing. With simple structure, uniform discharge and low investment cost, it is a cost-effective preferred model for small and medium-sized sand production lines.

Q：What are the core advantages of PLFC vertical shaft hammer breaker compared with ordinary crushers?

A：This machine integrates hammer crushing, roller shaping and ultra-fine crushing, with large crushing ratio, fine material output, good grain shape, low dust and low noise. The design of no sieve bottom completely eliminates the problem of material blockage, and wet materials and mixed materials can be produced stably. The energy consumption of the whole machine is low, which can effectively improve the production capacity of subsequent grinding and sand-making equipment by 30%-50%, and the comprehensive production efficiency is higher.

Q：What is the role of PLFC vertical shaft hammer crusher in the production line?

A：PLFC vertical shaft hammer crusher is usually used in the middle crushing or fine crushing stage of the crushing production line, and can also replace counter-fracting under some working conditions. In the whole sand and stone production line, it is mainly used to further crush medium-grained materials to finer-grained materials to provide suitable raw materials for subsequent screening or sand-making processes.

Q：How stable is the operation of the equipment? Is the failure rate high?

A：The vertical compact structure of the whole machine, the rotor dynamic balance is optimised, the operation vibration is small, the sealing is strong, and there is less dust. The core components are heat-treated and tuned + hydraulic correction technology of our factory. The fuselage is not easy to deform, withstand heavy loads and continuous operation, with a solid structure, few failures, and simple daily maintenance.

Q：Can non-standard size vertical shaft hammer breaking accessories be customised?

A：Support drawing customisation, sample reproduction, 3D modelling customisation of all kinds of non-standard wear-resistant parts, shaped liners, special hammers, can be adapted to new and old models, modified equipment, special working conditions production lines, and solve the problem of difficult procurement of special-shaped accessories on the market.

Q：What trade terms are used for export? Are the packaging and logistics safe?

A：Our company has a unified FOB trade mode, and the equipment adopts professional anti-rust treatment, waterproof winding, and reinforced packaging of export wooden boxes to prevent sea freight rust, bumping and deformation. It can provide packing real shots, shipping videos and a full set of customs clearance documents, and the export process is mature and stable.
