Large crushing ratio, high output, 1.4 times higher than domestic similar products, high efficiency, energy saving, wearing parts with high hardness, high toughness, multi-alloy wear-resistant material, life expectancy increased by 2-3 times, hammer and counterattack The gap between the plates is adjustable to meet a variety of material conditions;

2. The composite crusher is a combination of similar crusher technology at home and abroad, with the advantages of impact breaking and hammer breaking. The new fine crushed and coarsely ground products are optimized and designed for the main technical parameters. They are mainly used for medium and small crushed cement raw materials and clinker. They are used in construction sand, iron ore, sandstone, gypsum, coal gangue and lump coal. And other medium hard ore crushing;

3. It has the characteristics of large crushing ratio, low energy consumption, stable operation, simple structure, convenient operation and maintenance, etc. It is a kind of new multi-purpose, high-efficiency and low-cost new crushing equipment.

Five, compound crusher maintenance

The three-level maintenance system of the composite crusher embodies the shift of the focus of equipment maintenance management in China from repair to maintenance, and the maintenance management policy based on prevention is more clear. The three-stage maintenance system of the composite crusher includes: daily maintenance of the crusher equipment; primary maintenance and secondary maintenance. The three-level maintenance system is a mandatory maintenance system in which the operator is mainly responsible for the protection of the equipment and the warranty is important. The three-level maintenance system relies on all employees, giving full play to the enthusiasm of all members, implementing group management, combining groups, and improving the effective maintenance of equipment.

1, daily maintenance

The daily maintenance of the composite crusher equipment generally has daily maintenance and weekly maintenance, also known as daily maintenance and weekly maintenance;

2, first-level maintenance

The first-level maintenance of the composite crusher is based on the operator, the maintenance worker assists, partially disassembles and inspects the equipment according to the plan, cleans the specified parts, clears the oil circuit, pipeline, replaces or cleans the oil line, felt and oil filter. Adjust the matching clearance of each part of the equipment and fasten the various parts of the equipment. The time for the first-level maintenance is 2-4h. After the completion of the first-guarantee, the record should be recorded and the defects that have not been cleared should be recorded. The mechanical and electrical equipment department should check and accept the operation. Fill in the maintenance record in detail, and submit the acceptance form to the equipment department for filing;

3, secondary maintenance

The secondary maintenance of the composite crusher equipment is mainly based on maintenance workers, the operation workers participate in the completion, the secondary maintenance is included in the equipment maintenance plan, the equipment is partially disassembled and repaired, the worn parts are replaced or repaired, and the oil is cleaned and changed. Check and repair the electrical parts so that the technical condition of the equipment fully meets the requirements of the required equipment integrity standards. The time for secondary maintenance is about 1-3 days. After the secondary maintenance is completed, the maintenance workers should fill in the maintenance records in detail, and the mechanical and electrical equipment department Acceptance with the operator, the acceptance form is handed over to the Equipment Section for filing.

Sixth, troubleshooting

1, the phenomenon of failure: fine-grained

reason: more hammers;

Solution: Reduce one or two layers of hammers;

2, failure phenomenon: coarse grain size

Reason: loose belt or low speed;

Solution: tighten the belt and check if the voltage is 380V;

3, failure phenomenon: broken body swing

Reason: The centrifugal force of the rotor is not balanced;

Solution: Replace the new hammer or adjust the weight of the pusher.

Seven, composite crusher repair

1. The vertical composite crusher has a large crushing ratio, and the maximum crushing ratio can reach the discharge granularity and can be adjusted arbitrarily, which is not affected by the wear of the hammer and the lining;
