Longyi New-type grinding roller mill series is a new grinder depending on its technology R&D capability and referring to similar products' advantages home and abroad. It has comprehensive mechanical crushing properties such as rolling, grinding and impacting. According to clients' different requirements to finished powder, our company can provide diverse and customized solutions to help clients produce customized powder products. This series has such features as large output, lower energy-consumption, long operating Life and easy to maintenance. It is a perfect option for customers who prefer high return from investment.

After absorbing advantages from foreign superfine vertical mills and considering analysis of domestic clients' needs, Longyi makes targeted improvements on existing vertical mill's technology to develop a new-type vertical mill fit for superfine grinding of nonmetallic minerals. Self developed upgraded multi-head vertical classifier structure, Longyi classifier perfectly slove particle cutting point high and low sieving rate, compare with the traditional classifier, it fully ensure the powder quality that the finished  powder fineness could  reach 30%-60%  (particle size <2um, Detection machine: Malvern Micro laser particle size analyzer).After years of research and development Longyi new abrasion-resisting alloy steel is successfully applied in grinding rollers, grinding bearing and other parts, and it extremely endows the wear-resistant parts long service life, promoting the wear parts replacement cycle.

Longyi ultrafine impact mill is our self-developed powder equipment with high-efficiency and multi-purpose,which has the significant technical advantages of low energy consumption, accuracy fineness, abrasion resistance, and full functionality, and has become the preferred equipment for many industries. This machine is widely used in powder material ultrafine powder crushing, dispersing,modifying, the whole process of minerals crushing and modifying or pin-like fiber material processing.

Longyi powder coating machine is composed of three modificating cylinders, the material and modifier are continuously input into the cylinder automatically, the vortex two-phase flow will disperse them by the heat generated by the physical action between the rotor and the material, so that the material and modifier evenly speard over the surface of the powder, and modify the surface of the particles.

It is a deep processing powder-making machine, which is developed by Longyi R&D Team based on the requirements and opinions of domestic and foreign clients. It is a kind of mechanical and airflow- type mill. It is a multi-functional machine that integrates the functions of depolymerization, drying, powder coating and surface modification. It can flexibly match all kinds of mills and greatly increase the added value of powder products, and can be widely used in the field of powder deep processing.

It is a new type of powder processing equipment developed by Longyi based on its existing technology research and development capability and combined with user requirements. Longyi de polymerizing machine adopts continuous operation, which is mainly aimed at the increase of particle size of powder due to powder encapsulation and agglomeration of modified materials in the reactor, so it can depolymerize and break up the powder without destroyingthe original particle size. At the same time, this equipment can be used for material surface modification and shaping to improve the density of vibration and change the shape of the particles.

In order to meet clients' requirements for different fineness, Longyi R&D team developed the new upgraded classifier to classifying powder. It adopts direct-connected motor style impeller classifying system technology, also could collocates with electronic frequency converter to achieve step less speed adjustment to suitable for classifying different fineness powder, after that to realize high degree automation. Longyi air classifier with a compact structure could save space, even could match with different kinds grinding mills flexibly such as (grinding roller mills, ball mills, Raymond mills) etc, and works in a closed circuit system.

Longyi color sand making machine is a new machine depending on its technology R&D capacity. It has comprehensive mechanical crushing properties such as shearing, grinding, impacting. With uniqe designed grille, it could reduce the repeated grinding for finished products and increase the yield, it is an ideal sand making machine.

Longyi wet mill is large superfine grinding equipment developed by our company after improvements. It can crush materials into powders at level of 2000-6000 mesh or even finer through scientific grinding medium ratio, longyi wet mill works continuously by feeding materials from the base through pump, after which frequency conversion motor drives main shaft at stable speed to grind the ball and materials and generate high-energy movement among materials and medium ball, creating crash, shear and friction so as to meet best powder requirement. Longyi wet mill can operate independently for processing nonmetallic minerals including calcium carbonate, barite ,clay, gypsum and talc etc.

The LYZX series Shaping Machine is a new type of powder shaping equipment independently developed by Longyi, integrating mechanical and airflow methods. It is a versatile machine that combines shaping and dispersion functions into one. The shaping machine can flexibly match various grinding machines and significantly improve the performance of powder products. It can be widely applied in the field of shaping negative electrode material powders.
