LM series vertical shaft impact crusher has a long history of design and production in China, which has the characteristics of high reliability, convenient use, installation and maintenance, and various crushing forms (stone to stone, stone to iron, iron to iron) to meet different crushing needs of users. A variety of components are optional, and the key components are well-known foreign brands; The area of materials suitable for crushing is large; Low operation and maintenance cost and good economy; Energy saving, environmental protection, no need for any additional equipment, etc. Not only widely used in extremely hard materials. It is also suitable for fine grinding and ultra-fine grinding in industries with great differences in material properties such as artificial sand making, pre-grinding cement and refractory materials. Such as granite, basalt, limestone, quartzite, gneiss, cement clinker, concrete aggregate, ceramic raw materials, iron ore, gold mine, copper mine, corundum, bauxite, silica, etc.

The production of rotary crusher has a history of 100 years. Compared with the hammer crusher, the product has the advantages of uniform particle size, small abrasion of crushing wall, high working rate and production capacity as high as 3-4 times. Because the direct-turning feeding can be used, when it is selected as the crushing production process, the production facilities such as raw ore bin and feeder can be omitted. It is the first choice for coarse crushing of various hard materials in large and medium-sized mines and other industries.

Usually, the hydraulic gyratory crusher is produced, that is, a hydraulic device is installed at the lower part of the frame to support the crushing hammer. By using the energy storage hydraulic system, the safety of the crusher and the adjustment of the ore outlet are realized, which overcomes the shortcomings of the original hanging shaft gyratory crusher safety device that is unreliable and the adjustment of the ore outlet is troublesome, and makes gyratory crusher rejuvenate.

LM series fine sand recovery device is a fine sand recovery machine with international advanced level, which is designed by our company by absorbing foreign advanced technology and combining with China's actual situation. It is widely used in mud purification, sand and gravel aggregate system of hydropower station, glass raw material processing system, artificial sand production line and coarse slime recovery and environmental protection engineering of coal preparation plant, and dry discharge treatment (mud purification) of nonmetallic concentrator tailings in metal box of shield machine.

Advantages and characteristics:

1 in the process of wet production of artificial sand, the loss of a large amount of sand brings great pressure to the environment. In order to solve this problem, the LM fine sand recovery system produced by our company can effectively reduce the loss of fine particles and solve the problems of high fineness modulus and low stone powder content of finished products.

Using fine sand recovery system can not only make full use of resources, but also reduce the pollution of working environment and the workload of sedimentation tank. The fine materials in the total discharge can be recovered as high as 85%, which has incomparable technical and economic advantages compared with other equipment.

In the traditional mineral processing technology, most of the raw ore is crushed to below 0.2 mm by crusher, and the concentrate is extracted by water-soluble magnetic separation or shaking table, while most of the tailings are solved by damming and stacking. According to the above situation and national requirements for the environment, our company has designed a dry tailings discharge system, through which tailings can be directly stacked and discharged, which greatly reduces the production cost of mineral processing, effectively controls the water content in the mineral processing process, and well solves the problem of tailings discharging to the environment, which meets the requirements of environmental protection.

According to the field situation, the size of dewatering screen can be increased to increase the water content of tailings.

LMZ series dewatering screen is a continuous screening equipment developed by our company for dewatering, removing medium and mud of slurry materials. The trajectory of the screen box is roughly straight.

There are two types of power devices for LMZ series dewatering screen: directly driven by vibrating motor (smaller model) and driven by ordinary motor through coupling. The screen surface is made of stainless steel, nylon and polyurethane, which can be selected according to the actual situation of users.

The installation methods of LMZ series screen machines include pedestal type, suspension type and suspension seat combination type. Unless otherwise specified by the user, it defaults to pedestal type.
