GJ series sealed assay sample preparation grinder is mainly used for pulverizing raw materials for assay use such as coal, coke, gangue, various ores, etc. Its working mode is vibration grinding type. The particle size of the ground material is less than 13 mm. The compressive strength of the ground material is 800kg/cm2.

      This machine has been widely used in construction industry, metallurgical industry, mining industry, coal, coking, chemical industry, non-ferrous metal smelting and other industries.

Sealed sample preparation crusher, working principle and structural characteristics:

      This machine is mainly composed of: shell, base, shock absorption part, power part, grinding part, pressing part, etc.

      The shell is made of cold-rolled steel plate, which wraps the whole machine and plays a sealing, safety and aesthetic role. The base is made of good shock-absorbing material, which can effectively contain the instability and vibration of the machine when it is working.

      The shock absorption part is composed of superior springs and rubber. The spring has the advantages of high strength, high performance and high elasticity, which can effectively reduce the vibration to a low point and then transmit it to the base. The bottom of the base is equipped with shock-absorbing rubber piers to form a double-acting shock absorption effect, which can make the machine operate smoothly and reduce vibration and noise.

      The power part is composed of a motor, an eccentric hammer, a supporting steel cylinder, etc. When the motor is started, it drives the eccentric hammer to rotate. Due to the action of different centers and eccentric hammers, a high-speed peripheral body movement is formed, and this movement is transmitted to the grinding part. The support cylinder is used in conjunction with the top and bottom. Since the support cylinder is a closed device, it also plays a role in controlling unsafe accidents caused by eccentric violent vibrations.

      The grinding part is mainly composed of a pot seat, a crushing pot, a crushing ring, a crushing hammer, etc. After the grinding part receives the power of the power part, the crushing ring and the crushing hammer are frequently impacted and ground in the crushing pot under the high-speed peripheral body operation. Under this action, the material is impacted and ground into the required fine powder.

      The pressing device is composed of a pressing lever and a pressing screw, and its function is to firmly fix the grinding machine parts on the vibrating disc, so that the power can be effectively transmitted and it can play a safe role.
