stone production line also recognized as sand producing production line. it is the unique production line for generating sand and stone utilized in construction, road, and railway industries. the stone crushing equipments consist of jaw crusher, stone crusher, impact crusher, vibrating feeder, vibrating screen, sand washer, and belt conveyor and so on. the equipments manufactured by our business have the benefits of dependable performance, affordable design, straightforward operation, and high efficiency.

Rock broken is the craft and theory that make part of rock mass in mining assignments break away from matrix and then crushed into rocks. In stone production line there are usually four methods as follows.

1. Shooting water type flow broken method including high flow rate with low pressure and high pressure with small flow rate. The former pressure is not more than 2 x 107 Pa, which is used more for hydraulic mining or coal mining; The latter pressure can reach several hundred million palmer (Pa) or above, which is used for cutting rock. In addition, there is the pulsed jet technology with which solid rocks can be effectively broken without a great power. Currently the highest instant pressure has reached 5.6 GPa.

2. Thermal type broken method, which can create high temperature gradient in the rock, make use of various components of the thermal expansion coefficient and produce thermal stress, so that make rock flake or crisp fragile. The method is more helpful for rocks including many quartz. To a service-oriented brand integrity,As the professional manufacturer of complete sets of mining machinery,

3. Explosive broken method. It crushes rocks with the great energy released at eh moment from explosive or other explosives.

As a manufacturer of mining machinery and equipment industry, Hongxing Mining Machinery has made the business idea that we strive to be your most satisfied partner since the company was established. We try to fulfill our social obligations with the excellent quality and make great contribution to the society to build a strong brand in mining machinery industry. Hongxing Mining Machinery active participates the machinery and equipment seminars and exhibitions to display Hongxing brand strength for the public. As a member of the Council of the China Association of gravel, Henan Hongxing Mining Machinery actively participates all the activities of the associations, pays attention to the sand and gravel production market, adheres to the aim of the association, assists the government to improve industry management, regulates the industry fair competition order, maintains industry legitimate rights and interests and promotes industry innovation and development to promote the sustained, orderly and healthy development of the industry and assume the responsibilities for the development of the industry.

4. Mechanical broken method. There are four ways: cutting, blunt cutting, roller compaction and grinding. When rock broken, thesand maker is used into rock, and close-grained nuclear appears in the mass in the front of moving rock fragmenttation tools. There are large broken body around the close-grained nuclear.

This production line is able to crush various kinds of rocks, sand and river cobble into building-used sand with diverse granularities, and the final sand is even in granularity and high in compression strength so that is can better improve the quality of the buildings. This machine has many advantages such as reliable performance, reasonable design, convenient operation and high working efficiency. Hongxing Machinery has work-class production lines and modern test base and all the products are designed, produced, assembled and tested according to the ISO9001:2000 international quality certification system standard. The crushing equipment and industrial powder grinding machine series of products have been widely used in power station, mining, metallurgy, construction, chemistry, steel and oil and other industries.
