Product Description

Energy-saving grate ball mill for mineral processing plant

Working principle
the transmission device drives cylinder to rotate. materials and water are fed from the feeding end of cylinder and materials are grinded by impact and grinding of steel balls and ores into fine particles. the continuous grinding compels the slurry to move from feeding end to discharging end. grate type discharging device compels the grinded slurry outside the cylinder to avoid the over-grinding fault. compared with the same size overflow ball mill, the grade ball mill can achieve more capacity and obtain bigger particle-size products. adopting rolling bearing can reduce the starting energy and is convenient for maintenance. 



Features
large double row self-aligning rolling bearings or hybrid bearings are used to reduce the friction force which is easy for starting and the energy is saved by 20-30%. 
grooved ring high manganese steel liners are used to increase the contact surface of ball and ore, strength the grinding, lift the ores, and reduce the energy consumption. 
the steel frame can be used for the ball mills with diameter 2.7 meters or less in order to design and manufacture the modular plant, reduce the amount of civil construction and install the machine easily. 
large discharging outlet is designed for more capacity. 
depending on the customer's site conditions and demands, the electric motor is selected high-voltage or low-voltage type, and the liner materials can be high manganese steel or wear-resistant rubber. the brand of the motor or reducer can be chosen by the customer freely. 
it is recommended that the ball mills equipped the hybrid bearings should have the hydraulic jacks to lift the cylinder easily for installation and service. 
the ball mill runs smoothly and reliably. 
the big diameter ball mills have the inching driving device for easy starting and convenient maintenance. 
the air forced grease spaying atomizer ensures the perfect lubrication of the pinion and girth gear. 



Application scope
generally is used for the primary grinding or the product size -200 mesh less than 70%. 
ball mill is one of the most commonly used mining equipment, which is widely used in mineral processing, construction materials, silicate and chemical industries. in the production of small scale, medium scale or large scale mineral processing plants, it is generally used as the grinding machine for metal ores of gold, silver, copper, lead, zinc, nickel, manganese, iron, molybdenum, chromium, tin and others, as well as limestone, barite, quartz, graphite, feldspar, fluorspar, etc.

1. what is the main business scope of your company? 
hze is a company with r&d center, design institute, manufacturing factories, installation and commissioning teams. our customers are in the mining and mineral processing fields. our major businesses include mineral processing epc (engineering, procurement and construction), project consultation, engineering design, mineral processing equipment manufacturing, on-site installation, commissioning, staff training, customer project operation management, spare parts supply and technical support. customers are free to choose any one or any combination of our services. 


2. what are the outstanding advantages of your company? 
the one-stop service of mineral processing engineering project and equipment is our core competitiveness.
