Unparalleled anchor digger MB670-1 in sandvik

The anchor digger produced by sandvik Company has proved itself in the harsh continuous coal mining application for more than 30 years. sandvik MB670-1 is the latest generation anchor digger produced by the company, which has made many improvements in production efficiency and environment, health and safety (EHS).

Sandvik MB670 anchor digger is the flagship product of sandvik Company, which is used for roadway development in long-arm face mining. This kind of mechanical continuous coal mining operation, together with hydraulic roof support and long arm shearer, is mainly used for coal mining in Russian, Indian, Australian and China countries. In fact, the use of long-arm coal mining equipment in China accounts for more than 90% of the world. Sandvik is the leader in the global anchor digger market, and our customers are all over the world. They have nearly 300 Taishan Tevik anchor diggers.

Sandvik has been deeply involved in the field of long-arm mining equipment for more than 20 years, and its global sales volume has reached hundreds. It is a leading supplier of long-arm mining equipment. However, even the best equipment needs continuous upgrading to meet the evolving needs of customers. Sandvik is committed to actively maintaining and strengthening the position of its products relative to other advanced anchor diggers, and helping new customers and markets to improve safety and production efficiency. Modularization of electro-hydraulic system between different fire protection standards and machine products is also one of the goals pursued by sandvik.

Sandvik MB670-1 and all traditional models are based on the patented design concept of cut structure, which integrates cutting and bolt support, and can carry out full-face excavation independently of the main frame and crawler, and also support the roof and side of roadway.

According to the feedback of customers' on-site opinions, sandvik summarized customers' needs into the following five aspects: the equipment should have the functions of data recording and automatic cutting cycle; Reducing process cost and total operating cost is the eternal need of customers; Equipment mean time between failure must be extended; Customers have stricter requirements for safety performance; There is always pressure to improve production efficiency.

Sandvik has always been committed to systematically satisfying various demands put forward by customers, and constantly improving machine performance, thus bringing tangible benefits to mining companies, contractors, individual operators and maintenance personnel.

Sandvik MB670-1 is equipped with automatic cutting cycle function for the first time, and the cutting head of this machine can move to the predetermined coordinate axis within a predetermined time window. The same cutting process is repeated repeatedly, which makes the coal mining operation more efficient. A flatter roadway floor can reduce the damage to machinery and improve safety. The adjustable water bin improves the accuracy of coal screening. The anchor digger itself only produces less wear. These works

Performance characteristics can not only improve production efficiency, but also reduce total operating costs.

In addition, the electro-hydraulic system of the new sandvik MB670-1 has also been upgraded, including the adoption of new simplified hoses, contact arrangement and a more compact new power pack, as well as a new switchboard, display and remote control system.

Compared with the original products, the two most important improvements of the new generation anchor digger should be the new spool monitoring system and the strategically introduced emergency stop function. The spool monitoring system is essentially a safety device. If the spool is detected to be in the open position, it can automatically prevent the machine from starting, which will cause the parts to move instantly.

In addition, in the process of upgrading and improvement, the company has also paid great attention to mechanical parts and systems. The performance improvement includes: removing the tooth sleeve of the cutting drum by injecting oil into the tooth seat; Using new wear-resistant materials to prolong the service life of anchor rod, sliding and loading device; And a large number of unique improvements in structure and maintenance. Because it doesn't need much manual work, the improved anchor digging machine not only improves the safety performance, but also improves the production efficiency and reduces the total operating cost by simplifying the maintenance.

The most important innovation of MB670-1 subsystem in sandvik is the new wet dust removal fan system. Compared with the previous generation, the redesigned dust removal fan releases lower noise. The noise value is reduced by more than 10% on average, from 90-100 decibels to 77-90 decibels, depending on the type of dust removal fan.

Like other industries, coal miners are eager to use modern data acquisition and transmission systems. Sandvik MB670-1 can display data in real time. This function can read the status, running time, counters and other customized contents of the machine independently of the equipment, and it can be done through any computer connected to the mine network without installing any software. The data provided by the machine enters the mine network through OPC data interface.
