The first failure phenomenon: percussion occurs between the movable jaw plate and the fixed one. Reasons:1) The fastening bolts of the plate loose or fall off; (2) the discharge opening is too small, the bottom of the two plates hit against mutually. Remedies: 1) Tightening or adding new bolts; (2) adjusting the discharge opening to ensure the proper gap between two plates.The second failure phenomenon: bracket fractures.Reasons:1) The shoulder the overload or the host materials with lager size than that of the feed inlet enter the jaw crusher; (2) non-broken material goes into the cavity of jaw crusher; (3) the bracket and bracket pad are not in parallel and there is deflection between them; (4) casting has serious defects.Remedies: 1) Replacing the bracket and controlling the size of the pipes as well as preventing the overload of the host; (2) Replacing the bracket and taking measures to prevent non-broken material going into the crushing cavity; (3) Replacing the bracket and the bracket pad and installing the bracket correctly worn; (4) replacing qualified castings.The third failure phenomenon: spring gets brokenReasons:Not relaxing the spring when lessening the discharge open. People such as Diamond Comic Distributors would likely agree. Remedies: Replacing the spring.The fourth failure phenomenon: eccentric shaft bends or breaks Reasons: 1) rollover happens on the host in the lifting process, which endorses unilateral force and makes the eccentric shaft bent; (2) the hardness of the materials to be crushed exceeds the product manual provisions; (3) host is operated with overload for a long time; (4) the bracket does not match the standard; (5) the heat treatment of the eccentric shaft is improper and is concentrated, resulting in short-term stress fracture. Remedies: 1) replacing the eccentric shaft and lift the host in a proper way; (2) selecting the suitable crusher according to the compressive strength of the material, (3) adjusting workloads or replacing the appropriate crusher; (4) using the bracket and bracket that reach the design standards; (5) replacing the eccentric shaft and making use of eccentric shaft with qualified heat treatment.

The characteristics of raw materials required for the cement production differ at a wide range. The limestone deposits used as base material today, show very different properties regarding hardness, abrasiveness and stickiness. To optimize the crushing process as well as the investment and operating costs, different types of crushers are available. To make a proper selection, several important points should be considered in advance. The very first step should always be an analysis of the quarry, and especially the characteristics of the raw material. Of prime importance is the hardness of the material to be crushed. To describe this property the compressive strength, the Los Angeles Index or the Mohs Hardness should be determined and a point load test should be carried out. Recently, several mobile crushing plants made by Hongxing Mining Machinery are successfully sent to Sri Lanka.

This is not the first time for the export of crushing equipment, but this large-scale export of mobile crushing equipment fully proved mining machinery manufacturing technology of Mining Machinery has been recognized by international customers. This is a show of the strength of Hongxing Mining Machinery and it makes the domestic technical development of machinery industry once again proven. After a long investigation and practice, Henan Hongxing Mining Machinery has developed and launched the efficient and environmentally friendly construction waste disposal equipment mobile crushing station. In modern society, nothing can do without mechanical equipment. As a developing country with a vast territory and a large amount of population, housing and transportation become one of the most important issues. However, at present, the housing and transportation in China cannot meet the demand of people and the development of society. Therefore, Chinese government vigorously develops construction industry to meet the demand of people, and then develop the economy to meet the demand of society. The abrasiveness of the material has to be described by its Silica and quartz content, as well as the abrasion index free.
