Scope of application:

GJ-series sealed test sample preparation machine is applied to coal, electric power, scientific research and other industries or departments to pulverize the coal, ore, rock or medium hard non-metallics and brittle metallics.

Main features:

1.Uniform granularity during sample preparation, fast speed and reliable operation, typically complying with international standards.
2.Direct sample preparation without sieving, fewer process flow and high production efficiency.
3.No dust pollution because of sealed design of pulverizing room, conforming to environmental requirements.
4.Stable operation and little noise, satisfying requirements of safety production.
5.Steel optimal, bowls, shock, shock, gland, using manganese steel, corrosion resistant to grind.
6.The sample granularity, made with GB474 < representative national coal sample - 1996 Making declarations >, < scheme GB1997-89 coke sample preparation and adopt >.
7. Process, sample preparation (grinding) fast, short time, high efficiency, timing, fully adjustable without dust outside Excessive.
8. Advanced design, beautiful shape, structure, smooth operation, solid noise, high safety coefficient and longevity Life long, reliable operation, convenient operation and maintenance, and is superior to other similar products.

Overview of the structure

This machine is mainly composed of: shell, base, shock absorption part, power part, grinding part, pressing part and so on.
1. The shell is made of cold-rolled plates. The whole machine parts are packaged to be sealed, safe and secure Aesthetic effect.
2. The base is cast from a good shock-absorbing material, which can effectively curb the instability and vibration when the machine is working.
3. The shock absorbing part is composed of high-quality springs and rubber, and the springs have the advantages of high strength, high performance and high elasticity, which can effectively reduce the vibration to the lowest 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-absorbing effect, which can make the machine run smoothly and reduce vibration and noise.
4. The power part is composed of a motor, an eccentric hammer, a support cylinder, etc., and when the motor is started, the eccentric hammer is driven to rotate. Due to the action of the misalignment and eccentric hammers, a high-speed circumferential motion is formed, And this movement is transmitted to the grinding part. The support steel cylinder is used in an upward and downward connection, because the support cylinder is a closed device, and it plays a role in controlling the unsafe accidents caused by the violent vibration of the eccentricity.
5. 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, driven by the high-speed circumferential operation, the crushing ring and the crushing hammer frequently hit and grind in the crushing pot, and the material is hit and ground into the required fine powder under this action.
6. The hold-down device is composed of a hold-down lever, a press-down crankwheel or a quick press-in, and its function is to fix the grinding machine parts tightly on the vibrating plate, so that the power can be transmitted effectively and can play a safe role. The pressing part of this machine is advanced, which is different from other machines, and has the advantages: fast and safe, simple operation, adjustable up and down, which solves the phenomenon of unsafe and slow compression.

Installation and commissioning

The machine should be installed in a sheltered place from the rain, not in the open air. The machine is not fixed with anchor screws, but it should be placed on a flat ground, and the four anchor piers should be stable to avoid vibration and displacement. The power cord should be firmly connected, and the grounding wire should be safely grounded. Before starting the machine, it is necessary to carefully understand the performance of the machine, and be familiar with the structure, transmission characteristics and operating procedures of the machine. Check whether the bolts of each part of the casing are tightened, whether the motor power cord is leaking, the crushing pot body should be firmly placed, whether the pressing part is compacted reliably, and the shell lock should be locked.

Precautions for use

1. Before starting the machine, it is necessary to carefully check whether the bolts of each part of the casing are tightened, whether the motor power cord is leaking, the crushing pot body should be firmly placed, and whether the pressing part is compacted reliably.
2. Always check whether the crushing pot, crushing ring and crushing hammer are smooth, and replace them in time if there is a deep pit. 3. When the machine is running, pay close attention to whether there is abnormal noise, violent vibration, loose bolts and other phenomena, such as abnormal phenomena, must be stopped for inspection, maintenance, and normal trial operation.
4. When replacing the broken spring, it is necessary to replace 6 together or replace 2 separately, not only one, which will cause re-fracture and accident due to the uneven strength of the old and new springs.
