1. It is suitable for crushing medium hardness materials with compressive strength less than or equal to 220. Such as coal, metallurgy, ceramic raw materials potassium sodium feldspar, quartz stone and other solid materials in the fine crushing operation. Reliable performance, low power consumption, low maintenance cost (almost no daily maintenance) and so on.

2. The two motors are driven separately, with low failure rate, stable operation, low vibration, low noise and less dust.

3. The equipment is equipped with an automatic cleaning function, and the requirement for the moisture content of the material is low.

4. The equipment material box is high quality Q235B, and the main shaft material is 40Cr, all of which have been quenched and tempered by aging to ensure that the service life is not less than 20 years.

5. It adopts the high-quality bearing of the genuine tile shaft, the labyrinth design, and the oil seal of the double-layer skeleton bearing frame, so that the possibility of dust never entering the bearing seat is zero. With the rubber seal on the equipment box and the dust self-cleaning design, the possibility of dust entering the bearing seat and damaging the bearing is zero.

6. The equipment is equipped with automatic lubrication facilities, which can easily complete the daily maintenance work.

5. Manufacturing process

1. Structural parts manufacturing standards

Plasma cutting and carbon dioxide automatic protection welding are used, post-weld tempering heat treatment to eliminate stress, non-machined surface shot peening, surface painting is performed according to JB/T5000.12-1998, high-grade anti-corrosion primer is used, and enamel paint is applied on the surface.

2. Equipment quality standards, testing standards and testing methods

The quantity standard and testing standard adopt the national standard and industry standard JB/T 10245-2001 "roller crushing

Machine", JB/T and 11116-2010 "Roller Crusher" two industry standards, the test method is carried out according to the relevant technical conditions in the national standard and the corresponding national standard.

3. Features Overview

1) Effectively crush mineral materials, increase the agglomeration rate, and reduce the over-crushing rate.

2) The roller diameter of the crusher is large, and the angle between the two rollers is large, so as to ensure that the bulk materials are bitten and broken at one time.

3) Low roll speed and high torque are combined with special plane design and roll arrangement to obtain product particle size, so that the over-grinding rate is minimized. Due to its low rotational speed, the following characteristics are achieved:

Under field conditions (such as ore doped with iron, bolts and other sundries), the crusher has a good self-protection function and will not suffer serious damage, because:

① Low roll speed and heavy duty roll surface structure

② Stall protection

③ Secondary thermal trip switch

7) Equipment structure

① In the traditional structure, under the conditions of large feeding size and high hardness, the bearing positioning is not strong, and there is a problem of skipping and shifting shafts, which affects the service life of the bearing and fails to achieve the expected use function; and this innovative structure It The bearing and the box are organically combined, and the bearing is positioned reliably, which effectively solves the problem of skipping and shifting shafts, improves the service life of the bearing, and ensures the reliability of equipment operation.

② The traditional structural shell and the shaft are sealed by a rubber sealant plate. During the use process, the rubber plate is very easy to wear, resulting in dusty and harsh on-site environment at the crushing site. Our overall box structure effectively solves the problem. To solve this problem, the crushing space is a closed space as a whole, the crushing dust cannot fly out of the box, the crushing site is clean and tidy, and the environment is protected.

③ The overall box-type structure has a compact structure and beautiful appearance. It is equipped with a grinding roller that can repair the roller surface. After the roller surface is worn, it can be repaired, which greatly prolongs the service life of the broken box.

④ Application of sparse tooth net roll structure. The viscous and wet materials with large water content are easy to stick between the crushing teeth during the crushing process, resulting in the reduction of the crusher's ability to bite the material, and even unable to bite the material in severe cases, resulting in the accumulation of materials in the crushing cavity, resulting in a boring machine accident. Use the unit to cause economic losses. In response to this situation, the crusher is equipped with a sparse-toothed clean roller structure, which not only ensures the crusher's biting ability, but also ensures the particle size requirements of the product by forcibly removing the sticky and wet materials, and the sticky and wet materials are normally crushed.

⑤ The advanced sealing system ensures that the crusher operates in a harsh environment, and the bearing will not be damaged by dust, water, oil, etc. entering the bearing cavity.

⑥ The automatic dry oil lubrication equipment can carry out oil supply operation for a long time without interruption; the oil supply pressure is large, the oil supply speed is fast, and it is multi-point lubrication, which can fully lubricate the bearing and prolong the service life of the bearing.

8) Electrical control mode: local control box.
