Abstract
The utility model provides a MC dustpan shaped lining plate provided on the ball mill end cover, which is a group of dustpan shaped lining plates made of polymer synthetic material that is called MC coherent with a ball mill end cover. The shape of the utility model matches that of the ball mill end cover; each dustpan shaped lining plate is an integration or a combination of two parts. The tension intensity of the MC material is from 75 to 100 MPa; the intensity against bending is from 140 to 170 MPa; the intensity against compression is from 100 to 130 MPa; the intensity against impaction is from 7 to 9.6 MPa; the Brinell-hardness is from 14 to 21. The utility model has the advantages of solid connection between the MC dustpan shaped lining plate and the end cover, good sealing performance, abrasion durability, impaction prevention, light self weight and no environmental pollution. The utility model insures quality and accuracy of ore powder; lowers working intensity for workers and is convenient for maintenance and self-inspection.
Description
Technical field
The utility model belongs to the dustpan-shaped liner plate of MC of preparation equipment spare part, particularly a kind of end cover of ball mill.
Background technology
Ball mill is a kind of important preparation equipment, and in order to prevent the end cover of ball mill that weares and teares, the surface adds one deck liner plate within it.Conventional liner plate does not have enough strength and stiffness, can't bear the fierce impact of ore, and its abrasion resistance properties is poor simultaneously, often causes the breakage of end cover of ball mill body, increases maintenance and changes workload; Weight is big when adopting the irony liner plate, makes equipment self-weight big, easily causes self-inflicted injury in operation process; Because sealing is bad between end cap and the liner plate, has the slit, in the breeze flow process, spills a large amount of breezes, has reduced the quality and the precision of breeze, and serious environment pollution, therefore exhausts and wait to improve.
Summary of the invention
The purpose of this utility model provides a kind of brand-new end cover of ball mill liner plate, and this liner plate should have enough strength and stiffness, and has excellent abrasion resistance, can reach good sealing simultaneously and between the end cap.
According to the utility model, the dustpan-shaped liner plate of the MC of described end cover of ball mill is characterized in that this liner plate is that one group and the bonding employing of end cover of ball mill are called as the dustpan-shaped liner plate that the macromolecule polymeric material of MC is made, and its profile and end cover of ball mill match.
As a whole or formed according to each dustpan-shaped liner plate described in the utility model by two parts.
The tensile strength of described MC is 75～100MPa, and flexural strength is 140～170MPa, and incompressible intensity is 100～130MPa, and impact strength is 7～9.6MPa, and Brinell hardness is 14～21.
Because dustpan-shaped liner plate profile of the present utility model and end cap shape match, and bond together, so sealing is very good between end cap and the liner plate.Because whole liner plate is made up of one group of dustpan-shaped liner plate; and adopted the intensity height; the MC macromolecule polymeric material that anti-wear performance is good, every block of liner plate present dustpan-shaped, and this just makes whole liner plate have enough strength and stiffness; and has good decay resistance; therefore can play a good protection to end cover of ball mill, prevent that thoroughly dust from leaking, and protected environment; alleviate labor strength, reduced the maintenance load of ball mill significantly.
Description of drawings
Accompanying drawing 1 is for being installed in the structural representation of one group of dustpan-shaped liner plate on the end cover of ball mill.
Accompanying drawing 2 is the longitudinal sectional view of Fig. 1.
The specific embodiment
Below in conjunction with the description of drawings specific embodiment of the present utility model.
As shown in Figure 1 and Figure 2, the dustpan-shaped liner plate of the MC of end cover of ball mill is characterized in that this liner plate is that one group and the bonding employing of end cover of ball mill are called as the dustpan-shaped liner plate that the macromolecule polymeric material of MC is made, and its profile and end cover of ball mill match.
In the embodiment shown in Figure 1, one group of dustpan-shaped liner plate is 12, according to the ball mill concrete condition, and also can be with more or less liner plate number.
The profile of dustpan-shaped liner plate and end cover of ball mill body match as shown in Figure 2.
In specific embodiment, each dustpan-shaped liner plate is as a whole or be made up of two parts.
Adopt the dustpan-shaped liner plate of MC of end cover of ball mill of the present utility model, the tensile strength of described MC macromolecule polymeric material is 75～100MPa, and flexural strength is 140～170MPa, and incompressible intensity is 100～130MPa, impact strength is 7～9.6MPa, and Brinell hardness is 14～21.
Adopt the dustpan-shaped liner plate of MC of this end cover of ball mill of the present utility model and end cap in conjunction with firm, good seal performance, wear-resistant, shock resistance from heavy and light, does not have environmental pollution, not only guarantee the quality and the precision of breeze, also alleviated working strength of workers, be convenient to maintenance and self check.
Claims (3)
