Service Assurance

Our service commitment is not a slogan but a firm action. To this end, we have established enormous, systematic, and standardized service assurance system to ensure timely and proper handling of each service item.

How to get better product size

Good product size shall ensure that the ratio of the maximum size to the minimum size of more than 90% of the product is less than 3 (the smaller the ratio, the better the particle size). Product size is affected by many factors, the main influencing factors are feed, crushing chamber type, discharge port, crushing equipment and crushing process.

Correct feeding

The Second Hand Stone Crusher Equipment must be fully charged. The stable continuous grading material avoids the change of crushing force and feed grade, and maintains relatively stable crushing chamber and discharge outlet.

The product provided by wide graded feed is better than that of narrow graded feed. This part of material smaller than the discharge port in the raw material will increase the extrusion between the materials and have a good filling effect on the crushing chamber. Do not be too thin, it is better to be slightly less than or equal to the size of the outlet, and the ratio should not exceed 20%.

A large discharge port will bring more flaky products, so in order to obtain a good product size, a smaller discharge port is required, and the crushing ratio is controlled to 3 to 3.5. This requires controlling the feed size, preferably no more than 50 mm. Improper feeding will affect the production capacity of Second Hand Stone Crusher Equipment, and may lead to a series of problems, such as adjusting ring runout, shortening service life of bushing and poor grain size of crushed products.

Reasonable selection of Second Hand Stone Crusher Equipment and crushing chamber

Choose reliable Second Hand Stone Crusher Equipment and crushing chamber. Power, crushing force and discharge are three factors that determine the output and discharge size of Second Hand Stone Crusher Equipment. The way to increase the power is to increase the feed rather than decrease the discharge port. The best crushing force is about 80% of the rated power.

Adjusting the loop jump means that the crushing force exceeds the design limit. If the crushing force of Second Hand Stone Crusher Equipment is too large, the discharge port can be adjusted by 1mm-2mm. Adjusting the ringing and power peak will exert extra pressure on the Second Hand Stone Crusher Equipment, which will eventually cause serious damage to the Second Hand Stone Crusher Equipment.

Closed loop crushing system

Second Hand Stone Crusher Equipment is a part of the crushing system, other equipment will also affect the whole crushing system. The conveyor system must have sufficient conveying capacity. Whether the bin is buffered in front of the Second Hand Stone Crusher Equipment is very important to stabilize the filling of the Second Hand Stone Crusher Equipment.

The screening efficiency also has a great influence on the crushing system. Insufficient screening, on the one hand, will lead to too much fine material in the return, which is easy to cause overload of Second Hand Stone Crusher Equipment; on the other hand, too much qualified fine material will be returned to Second Hand Stone Crusher Equipment, which will reduce the production capacity of the crushing system.

The uncrushed foreign matter in the crushing system is very harmful to the Second Hand Stone Crusher Equipment. For example, iron may cause the copper crusher of Second Hand Stone Crusher Equipment, the frame to break and the main shaft to break seriously. In the second stage of crushing, the closed-circuit circulation crushing can provide accurate feeding size for the fine crushing and avoid too much fine material entering the crushing chamber, so that the crushing chamber can achieve the ideal filling effect.

Material properties and product granularity

Generally, the softer the rock is, the coarser the crystal particles of the rock are, and the thicker the product is, the better the shape of the broken particles is. For example, a product of 6-15mm is obtained. The second stage is broken by the closed circuit to break to less than 50 mm, and materials less than 6 mm are screened out to ensure relatively stable 6-50 mm continuous graded feeding.

Second Hand Stone Crusher Equipment has a great advantage in the field of crushing. Reasonable crushing system, correct equipment and cavity selection, and standard operation and maintenance habits can maximize the performance of Second Hand Stone Crusher Equipment.
