Our advantages: 1. High efficiency: in crushing, it adopts traditional two-stage and a closed circuit system for ideal fineness. Besides, jaw crushers have large crushing capacity. 2. Saving energy in grinding and classification, with characteristics of large processing capacity and small floor area, superfine lamination autogenous mill can save energy by more than 85%. 3. Good classifying effects :in classification, hydrocyclone and vibrating screen can enhance the classifying effects. 4. Environmental protection :i t adopts the third generation tailings dry stacking technology, which can save energy by 60-80%. Furthermore, it can also protect the environment and build a base for green mine. Production technology: Raw material ores is exploited from mountain are big size, so it is necessary to crush firstly, in this process, the raw materials will be feed into primary crusher by feeder, then come into secondary crusher.The materials will go into screen after first and secondary crusher, the suitable size material (â?¤25mm) will go to next step. Oversize(ï¼?25mm) material will go back to secondary crusher to crush again. This forms a closed crush circuit. In this process, material will be grinded into suitable sizes (about 200 mesh) for beneficiation.After grinding material will come to classifier. In classifier, suitable size material will go to next step. Coarse material will go back to ball mill for grind again. This process is a closed grind circuit. In this process, materials will be separated by flotation, magnetic separator or gravity concentrating machine. We will get the materials that we need. Process introduction: after beneficiation, there are some residual water in ore concentration. So we have to carry on concentrate dehydration to meet the requirements of transportation and smelting.

Equipment introduction 1. Current situation of granulating equipment At present, traditional disc granulator is mainly used in the domestic ceramic sand production. The price of this kind of equipment is low, but its capacity is small, pelletization rate is low and added ingredient is required.Especially, it leads to severe dust pollution, occupies a large plant area and labor intensity is large. Under the trend of increasingly high requirements and strict management of environment and labor protection in our country, it has become an inevitable choice for the healthy development of industry to eliminate this kind of granulating equipment out of time. In view of this, carbo corporate has pioneered in introducing german eirich rv15 granulators, achieving good economic and social benefits, drawing great attention from the domestic ceramic sand industry. However, eirich granulator is very expensive, which limits its widespread use in our country. Aiming at the urgent demands of technological upgrading in domestic ceramic sand industry, henan zhengzhou mining machinery co., ltd.Has successfully developed a similar kind of advanced granulator by the way of collaborative research and innovation. It is capable of fully meeting the requirements for clean and efficient production of a variety of ceramic sands 2. Highly effective and clean granulating system Zk-15 granulator is composed of main hopper, reversible spiral, main measuring bin and auxiliary measuring bin, constant dosing water tank, powder recycling processor, air fan, granulating host and complete control system. 3.Sample products of zk-15 After 8000 times of trial production as long as six months, zk-15 granulator developed by henan zhengzhou mining machinery co., ltd.Has achieved mixing uniformity of 99.9%, pelletization rate 16-80 mesh â?¥ 90%, discharging every 5-10 minutes.
Spiral classifier also can be called spiral separator, screw classifier or screw separator. It is widely used in the concentrator and make up a closed-loop with ball mill. We produce high weir type classifier, single and double spiral type classifier and immersed single and double spiral classifiers. Our spiral classifiers are widely used in the separation of ore in closed circuits with ball mills for the grading of ores and metal ore-dressing and other operations. This product is featured with simple structure, reliable working condition and convenient operation. Because different grains have different specific gravity and sedimentation rates in liquid, this product allows the fine ore to float in the water, while coarse ore sinks to the bottom. Features and benefits 1. Can be very convenient to control the content of sand powder and to meet usersâ?? requirements. 2. Spiral classifier has advanced technology, simple process, particularly suitable for large and medium-sized sand making production line. 3. The content of powder with size of 0.00--0.75mm is between 2%-15% and can be adjusted. 4. The quality of powder is easy to control. The adjustment of fine is convenient, flexible, and reliable. Working principle The principle used in spiral classifier is that different sizes of crushers have different weights, so their sedimentation rates are also different. In the working process, fine ore grains float on the surface of water, and rough grains sink on the bottom of the cell. Screw grader can classify materials from mill, and then bring the rough grains to the entrance mouth of mill with the help of flights, and discharge the fine ore grins though pipe. The pedestal spiral classifier is made of box iron. The body is made of welding steel plates. The faucet and spindle nose of screw shaft are made of pig iron set which is wear-resisting durable. The take-up sets include two types power-driven and manual operation.
A cone crusher is generally used as a secondary crusher in a crushing circuit. Pre-crushed product (usually 3in minus depending on the cone crusher model) is fed through the top of the cone crusher and flows over the mantle.

Two basic styles of stacker reclaimers utilizing three different configurations of trailing tripper structures typically meet most storage requirements for bulk ports, terminals, electric power stations and other facilities where efficient stockpile management of raw materials is essential. Trench-type stacker reclaimer is ideal for installations with low-volume, high-active storage pile capacities between 30, 000 and 60, 000 tons, where reclaiming operations are accomplished by a longitudinal pass through the pile. Reclaim rates usually vary from 2, 000 to 4, 500 tons. Slewing-type stacker reclaimers are typically used where large quantities of material must be readily available, where blending of grades of material is required or where available yard length is limited.
