Box type crusher

Box type crusher, also known as heavy hammer crusher and square box crusher, is a new generation of crusher products, which absorbs advanced technologies at home and abroad and integrates ordinary heavy hammer crusher, impact crusher, vertical shaft heavy hammer crusher and various machines that use hammer head (plate hammer) to strike and crush stone. In principle, after optimized design, it has manufactured and produced the latest generation of crusher products, changing the method of controlling the size of discharged particles with grate bar, The wear of the hammer head in the crushing chamber is reduced, and the service life of the hammer head is increased by 4-6 times. Each pair of hammer head can crush 30000-40000 tons of stone, realizing a major breakthrough in crushing technology and truly achieving twice the result with half the effort.
Product overview
The single hammer head of the box crusher has large weight, high rotor speed and large moment of inertia, which fully reflects the advantages of large breaking and small, heavy crushing and light crushing, and has the unique ability of nibbling crushing of super large stones.
working principle
The stone falls directly into the high-speed rotating rotary table from the upper part of the machine. Under the action of high-speed centrifugal force, it produces high-speed impact and high-density crushing. After hitting each other, the stone will form eddy motion between the rotary table and the casing, resulting in repeated mutual hitting, friction and powder crushing until it is crushed to the required particle size.
product mix
The frame part of the box crusher is a three-part structure. Just open the rear shell of the crusher to replace the plate hammer, crushing plate, lining plate and other maintenance operations. The box crusher has strong interchangeability and few varieties of vulnerable parts, which is convenient for the procurement and management of spare parts. The hydraulic opening device is used for opening and closing the casing, which can effectively reduce the maintenance labor intensity, improve the maintenance efficiency and shorten the maintenance time. The monitoring system of the box crusher can monitor the operation status of the crusher at any time, and the monitoring signal can be interlocked with the main control system to ensure the safe and reliable operation of the machine. The drive system of the box crusher adopts the mode of motor + mechanical coupling + V-belt + crusher, which can effectively improve the starting performance of the motor and make the motor start and run smoothly. The belt drive mode can play a dual function of overload protection. The motor power required by the drive system is low, which greatly reduces the operation cost. This driving scheme is economical, practical, excellent performance, safe and reliable.
Fold and edit the performance characteristics of this section
The development of new medium and fine gravel equipment is widely used to replace cone crusher, counter roller mill and ball mill in the world. Novel and unique structure and stable operation. It has the shaping function, and the product is square and has high stacking density. In the production process, the stone can form a protective bottom layer, and the body is wear-free and durable. A small number of easily worn parts are made of extra hard wear-resistant materials, with small volume and light weight, which is easy to replace parts. After the large materials are stacked in the crushing chamber along the tangent direction of the hammer, the large materials will be driven to the crushing plate in the middle of the crusher, and finally the materials will be stacked along the tangent direction of the crusher, so as to meet the requirements of the whole crushing plate.
Performance features
1. Large feed particle size, large crushing ratio and uniform discharge.
2. High yield, granular products account for about 85%, which fully meet the use requirements.
3. The installation of hammer shaft of box crusher is adjustable and the service life of hammer head is long.
4. The grid size is adjustable, the product particle size is controllable and the particle shape is good.
5. The case of box crusher can be turned over, which is more convenient for maintenance.
6. Square shank bolt, impact and wear resistance.
7. High output and stable performance.
8. Coarse and medium crushing are in place in one step, and the process flow is simplified.
9. The hammer head, grate plate and counterattack plate made of high wear-resistant materials have a longer service life.
10. Low supporting power, low energy consumption, simple maintenance and few vulnerable parts.
Scope of application
1. It is applicable to the primary and secondary crushing of various materials with compressive strength below medium and upper hardness.
2. It is especially suitable for crushing materials used in mining, building materials, chemical and metallurgical industries.
3. The compressive strength of the material shall not exceed 100 MPa and the humidity shall not be greater than 15%.

Maintenance outline
The accessories of box crusher shall adhere to the "cross" working method of cleaning, lubrication, adjustment, tightening and anti-corrosion, implement daily maintenance and regular maintenance system, and strictly check and repair the engineering manual according to the specified cycle.
Maintenance I: general cleaning, tightening and lubricating oil business, and in part adjust the operation and maintain the complete state technology of the crusher. The unit asset management machine is repaired and lubricated, and the operation team that realizes the maintenance procedure will control the equipment.
Repair 2: all contents, including repair and inspection, adjustment and maintenance, crusher assembly, mechanism and some parts have good working performance. For the lubrication and maintenance of the crusher, a notice is issued to the asset management company of the user unit to realize the operation team. I have completed the operator.

Development trend
With the continuous increase of mining machinery products, people's demand for mining equipment has also increased. The use of box crusher in society and PCL sand making machine have also increased slightly. And gradually become the main product of some enterprises. With the continuous progress of the economy and the continuous improvement of the social form, the box crusher meets the major needs of economic construction and successfully realizes the continuous progress of the economy. In addition, because of the pollution to the environment, the box crusher plays an important role in the environment. The cone crusher effectively reduces people's labor level.
Under the effect of high-speed separation of the box crusher, after the stones are pressed against each other, eddy current movement will be formed between the rotary table and the casing, resulting in repeated mutual pressure, friction and crushing until they are crushed to the required particle size. It is a production system of box crusher.
The belt transmission form of box crusher can play a dual function of reprinting, and the driving operation of box crusher can greatly reduce the operation cost. The mechanization degree of box crusher in Carboniferous, copper mine, zinc mine and other mines has been greatly improved, which has continuously strengthened the market volume of mining machinery and facilities.
Product structure of box crusher jaw crusher the frame of the box crusher is partially a three-part structure. The inspection, repair and protection operations such as changing plate hammer, crushing plate and lining plate can be carried out only by opening the shell at the rear of the crusher. The perfection of the box crusher improves the strength of the parts.
The box crusher is a stone breaking machine that our company absorbs the advanced technology at home and abroad, integrates the advantages of jaw crusher, hammer crusher, impact crusher and snail crusher, and integrates the advantages of jaw crusher, hammer crusher, impact crusher and snail crusher. The large stone is broken directly, fed automatically, and operated in a full-automatic flow. It saves people and labor, is efficient and energy-saving, and has a daily output of more than 1000 tons. It is the most advanced and applicable stone equipment in China at present, and is highly praised by users.
