Description

Crushing and screening device for mine stone processing

Technical Field

The invention relates to the related technical field of mining machinery equipment, in particular to a crushing and screening device for processing mine stones.

Background

The crusher is a machine for crushing large-size solid raw materials to required sizes, the crusher comprises devices such as coarse crushing, fine crushing, wind power conveying and the like, the purpose of the crusher is achieved in a high-speed impact mode, wind power is utilized for one-time crushing, a traditional screening program is cancelled, a stone processing crusher for ores is a device for crushing stones, and the stones can be classified into a coarse crusher, a medium crusher, a fine grinder and an ultra-fine grinder according to the sizes of crushed materials or crushed materials after being crushed. The external force applied to the solid in the crushing process comprises four kinds of pressing, shearing, impacting and grinding. The rolling is mainly used for coarse crushing and medium crushing, and is suitable for crushing hard materials and large lump materials; the shearing is mainly used for fine crushing and is suitable for crushing of tough materials; the impact is mainly used for medium crushing, fine grinding and superfine grinding, and is suitable for crushing brittle materials; the grinding is mainly fine grinding and superfine grinding, and is suitable for crushing small blocks and fine particles.

The crusher can be applied to different fields by different models, and the coarse crusher is mainly used for crushing pretreatment operation of various industries and mainly has the function of processing materials with larger diameter of 5-10cm to granular materials with smaller diameter of 5-10 mm. The pulverizer is mainly used for medium-fineness pulverizing operation in various industries and has the function of processing granular materials into medium-fineness powder with required diameter so as to carry out subsequent treatment or serve as a finished product. The ultrafine grinder is mainly used for ultrafine grinding operation in most industries, and is mainly used for processing raw materials of high-end products by grinding materials after grinding operation again to reach required material diameters. The small-sized pulverizer is mainly suitable for material pulverizing treatment in the industries of food, chemical industry, medicine, greening, environmental sanitation and the like on the premise of the same pulverizing fineness.

In the building stones processing in mine, we need use the building stones rubbing crusher, smash the back to building stones through the building stones rubbing crusher, again process the building stones after smashing, but the building stones rubbing crusher who uses commonly now is all about as much as the crushing effect of building stones, can not guarantee that the hundred percent smashes into the appearance that wants to reach, so will filter the building stones after smashing, but the ten thousand net designs of whole filter sieve tray are fixed unmovable form among the existing equipment, filter the sieve tray and to the screening operating efficiency of building stones low, smash the action and screen the action and can not carry out effectual "linkage" cooperation, traditional mode has two kinds of design drawbacks that move independently alone, the screening efficiency is low, it is poor to screen the effect.
