technical field

The utility model relates to the field of mining machinery, in particular to a crushing and screening machine for nickel alloy raw materials.

Background technique

Nickel ore crushing is an important process step in the field of nickel alloy metallurgy. According to different product particle size requirements, different crushing equipment is used. In order to meet the requirements for material particle size in the production process of the industry, roller mills are gradually researched and applied. Type crushers can crush larger materials. If you want to crush smaller sizes, you need to go through multiple grindings. The efficiency is not high. Roller mills have high efficiency, but they cannot crush larger materials. When the size of the ore is crushed to a small size, different pulverizers are required to classify the raw materials for processing and the crushing efficiency is low, and a large amount of dust is generated during the crushing process.

The screening system is respectively arranged at the bottom of the feed hopper and the bottom of the jaw crusher. A primary hopper and a secondary hopper are arranged obliquely below the screening system, a jaw crusher is provided at the bottom of the primary hopper, a roller crusher is provided at the bottom of the secondary hopper, and a jaw crusher is provided at the bottom of the secondary hopper. The machine includes a fixed jaw and a movable jaw.

As an optimization, the screening system includes a screening machine, a storage plate arranged at the bottom of the screening machine, and a sprayer arranged obliquely above the screening machine.

As an optimization, the sieving machine includes a sieving machine wall, a gear, a rotating shaft, a support arm, and a screen, the sieving machine wall is cylindrical, the top surface of the sieving machine wall is a curved surface, and the sieving machine wall is curved. A screen is arranged inside the wall, gears are arranged on the side wall of the sieving machine wall, support arms perpendicular to each other are arranged on the bottom surface of the sieving machine wall, and a rotating shaft is arranged on the support arm.

As an optimization, the gear is driven by a driving gear, the screening machine rotates around the shaft, and the bottom surface of the shaft is provided with an elastic device.

detailed description

In the embodiment shown in Figure 1, a nickel alloy raw material crushing and screening machine includes two screening systems 1, a material transportation system, and a crushing system. The material transportation system includes a feed hopper 2, a primary hopper 4, The secondary hopper 5 and the discharge hopper 3, the crushing system is composed of a jaw crusher 6 and a roller crusher 7, and the screening system 1 is respectively arranged at the bottom of the feeding hopper 2 and the bottom of the jaw crusher 6 A primary hopper 4 and a secondary hopper 5 are arranged obliquely below the two screening systems 1, a jaw crusher 6 is provided at the bottom of the primary hopper 4, and a jaw crusher 6 is provided at the bottom of the secondary hopper 5. Roller crusher 7 , the jaw crusher includes a fixed jaw 61 and a movable jaw 62 .

In the specific implementation process, the ore raw material enters the primary screening system 1 through the feed hopper 2, and the dust generated is removed by the water sprayed by the sprinkler 12. The ore falls into the primary hopper 4 and then enters the jaw crusher 6 for crushing. The crushed ore enters the secondary screening system 1, the dust generated is removed by the water sprayed by the sprinkler 12, and the ore that meets the specifications is screened into the The material storage plate 13, the ore with large particles enters the roller crusher 7 for crushing through the secondary hopper 5, and the final finished product flows out through the discharge hopper 3.

In the embodiment shown in Figure 2, the screening machine 11 is placed in an inclined shape, and the material falls into the higher point of the inclined screen 115. The screening machine 11 is driven by the driving gear to drive the gear 112 to rotate to achieve a good screening effect. When the ore Falling into the screening machine 11 causes an impact on the screen 115, which is supported by the support arm 114. At the same time, the elastic device arranged at the bottom of the rotating shaft 113 also plays a good buffering role, protecting the screening machine 11, and the vibration generated has also played a better role. Screening effect.
